In Our Time

Melvyn Bragg and guests discuss the 2000-year-old device which transformed our understanding of astronomy in ancient Greece. In 1900 a group of sponge divers found the wreck of a ship off the coast of the Greek island of Antikythera. Among the items salvaged was a corroded bronze object, the purpose of which was not at first clear. It turned out to be one of the most important discoveries in marine archaeology. Over time, researchers worked out that it was some kind of astronomical analogue computer, the only one to survive from this period as bronze objects were so often melted down for other uses. In recent decades, detailed examination of the Antikythera Mechanism using the latest scientific techniques indicates that it is a particularly intricate tool for showing the positions of planets, the sun and moon, with a complexity and precision not surpassed for over a thousand years.With Mike Edmunds Emeritus Professor of Astrophysics at Cardiff UniversityJo Marchant Science journalist and author of 'Decoding the Heavens' on the Antikythera MechanismAnd Liba Taub Professor Emerita in the Department of History and Philosophy of Science at the University of Cambridge and Visiting Scholar at the Deutsches Museum, MunichProducer: Simon Tillotson In Our Time is a BBC Studios Audio ProductionReading list:Derek de Solla Price, Gears from the Greeks: The Antikythera Mechanism (American Philosophical Society Press, 1974)M.

Melvyn Bragg and guests discuss the poet George Herbert (1593-1633) who, according to the French philosopher Simone Weil, wrote ‘the most beautiful poem in the world’. Herbert gave his poems on his relationship with God to a friend, to be published after his death if they offered comfort to any 'dejected pour soul' but otherwise be burned. They became so popular across the range of Christians in the 17th Century that they were printed several times, somehow uniting those who disliked each other but found a common admiration for Herbert; Charles I read them before his execution, as did his enemies. Herbert also wrote poems prolifically and brilliantly in Latin and these he shared during his lifetime both when he worked as orator at Cambridge University and as a parish priest in Bemerton near Salisbury. He went on to influence poets from Coleridge to Heaney and, in parish churches today, congregations regularly sing his poems set to music as hymns.

Melvyn Bragg and guests discuss the remarkable rise of Venice in the eastern Mediterranean. Unlike other Italian cities of the early medieval period, Venice had not been settled during the Roman Empire. Rather, it was a refuge for those fleeing unrest after the fall of Rome who settled on these boggy islands on a lagoon and developed into a power that ran an empire from mainland Italy, down the Adriatic coast, across the Peloponnese to Crete and Cyprus, past Constantinople and into the Black Sea. This was a city without walls, just one of the surprises for visitors who marvelled at the stability and influence of Venice right up to the 17th Century when the Ottomans, Spain, France and the Hapsburgs were to prove too much especially with trade shifting to the Atlantic.With Maartje van Gelder Professor in Early Modern History at the University of AmsterdamStephen Bowd Professor of Early Modern History at the University of EdinburghAndGeorg Christ Senior Lecturer in Medieval and Early Modern History at the University of ManchesterProducer: Simon TillotsonReading list:Michel Balard and Christian Buchet (eds.), The Sea in History: The Medieval World (Boydell & Brewer, 2017), especially ‘The Naval Power of Venice in the Eastern Mediterranean’ by Ruthy GertwagenStephen D.

Melvyn Bragg and guests discuss Louisa May Alcott's 1868 novel, credited with starting the new genre of young adult fiction. When Alcott (1832-88) wrote Little Women, she only did so as her publisher refused to publish her father's book otherwise and as she hoped it would make money. It made Alcott's fortune. This coming of age story of Meg, Jo, Beth and Amy March, each overcoming their own moral flaws, has delighted generations of readers and was so popular from the start that Alcott wrote the second part in 1869 and further sequels and spin-offs in the coming years. Her work has inspired countless directors, composers and authors to make many reimagined versions ever since, with the sisters played by film actors such as Katherine Hepburn, Elizabeth Taylor, Winona Ryder, Claire Danes, Kirsten Dunst, Saoirse Ronan and Emma Watson.

Melvyn Bragg and guests discuss the Austrian-British economist Friedrich Hayek's The Road to Serfdom (1944) in which Hayek (1899-1992) warned that the way Britain was running its wartime economy would not work in peacetime and could lead to tyranny. His target was centralised planning, arguing this disempowered individuals and wasted their knowledge, while empowering those ill-suited to run an economy. He was concerned about the support for the perceived success of Soviet centralisation, when he saw this and Fascist systems as two sides of the same coin. When Reader's Digest selectively condensed Hayek’s book in 1945, and presented it not so much as a warning against tyranny as a proof against socialism, it became phenomenally influential around the world. With Bruce Caldwell Research Professor of Economics at Duke University and Director of the Center for the History of Political EconomyMelissa Lane The Class of 1943 Professor of Politics at Princeton University and the 50th Professor of Rhetoric at Gresham College in LondonAndBen Jackson Professor of Modern History and fellow of University College at the University of OxfordProducer: Simon TillotsonReading list:Angus Burgin, The Great Persuasion: Reinventing Free Markets Since the Depression (Harvard University Press, 2012)Bruce Caldwell, Hayek’s Challenge: An Intellectual Biography of F.A.

Melvyn Bragg and guests discuss the author of 'I, Claudius' who was also one of the finest poets of the twentieth century. Robert Graves (1895 -1985) placed his poetry far above his prose. He once declared that from the age of 15 poetry had been his ruling passion and that he lived his life according to poetic principles, writing in prose only to pay the bills and that he bred the pedigree dogs of his prose to feed the cats of his poetry. Yet it’s for his prose that he’s most famous today, including 'I Claudius', his brilliant account of the debauchery of Imperial Rome, and 'Goodbye to All That', the unforgettable memoir of his early life including the time during the First World War when he was so badly wounded at the Somme that The Times listed him as dead.

Melvyn Bragg and guests discuss the notorious attack of 4th of May 1886 at a workers rally in Chicago when somebody threw a bomb that killed a policeman, Mathias J. Degan. The chaotic shooting that followed left more people dead and sent shockwaves across America and Europe. This was in Haymarket Square at a protest for an eight hour working day following a call for a general strike and the police killing of striking workers the day before, at a time when labour relations in America were marked by violent conflict. The bomber was never identified but two of the speakers at the rally, both of then anarchists and six of their supporters were accused of inciting murder. Four of them, George Engel, Adolph Fischer, Albert Parsons, and August Spies were hanged on 11th November 1887 only to be pardoned in the following years while a fifth, Louis Ling, had killed himself after he was convicted. The May International Workers Day was created in their memory.With Ruth Kinna Professor of Political Theory at Loughborough UniversityChristopher Phelps Associate Professor of American Studies at the University of NottinghamAnd Gary Gerstle Paul Mellon Professor of American History Emeritus at the University of CambridgeProducer: Simon TillotsonReading list:Paul Avrich, The Haymarket Tragedy (Princeton University Press, 1984)Henry David, The History of the Haymarket Affair (Collier Books, 1963)James Green, Death in the Haymarket: A Story of Chicago, the First Labor Movement and the Bombing that Divided Gilded Age America (Pantheon, 2006)Carl Levy and Matthew S.

Melvyn Bragg and guests discuss the tantalising idea that there are shortcuts between distant galaxies, somewhere out there in the universe. The idea emerged in the context of Einstein's theories and the challenge has been not so much to prove their unlikely existence as to show why they ought to be impossible. The universe would have to folded back on itself in places, and there would have to be something to make the wormholes and then to keep them open. But is there anywhere in the vast universe like that? Could there be holes that we or more advanced civilisations might travel through, from one galaxy to another and, if not, why not?

Melvyn Bragg and guests discuss one of the major figures in Victorian British politics. Disraeli (1804 -1881) served both as Prime Minister twice and, for long periods, as leader of the opposition. Born a Jew, he was only permitted to enter Parliament as his father had him baptised into the Church of England when he was twelve. Disraeli was a gifted orator and, outside Parliament, he shared his views widely through several popular novels including Sybil or The Two Nations, which was to inspire the idea of One Nation Conservatism. He became close to Queen Victoria and she mourned his death with a primrose wreath, an event marked for years after by annual processions celebrating his life in politics.WithLawrence Goldman Emeritus Fellow in History at St Peter's College, University of OxfordEmily Jones Lecturer in Modern British History at the University of ManchesterAnd Daisy Hay Professor of English Literature and Life Writing at the University of ExeterProducer: Simon TillotsonReading list:Robert Blake, Disraeli (first published 1966; Faber & Faber, 2010)M.

Melvyn Bragg and guests discuss the most abundant lifeform on Earth: the viruses that 'eat' bacteria. Early in the 20th century, scientists noticed that something in their Petri dishes was making bacteria disappear and they called these bacteriophages, things that eat bacteria. From studying these phages, it soon became clear that they offered countless real or potential benefits for understanding our world, from the tracking of diseases to helping unlock the secrets of DNA to treatments for long term bacterial infections. With further research, they could be an answer to the growing problem of antibiotic resistance.With Martha Clokie Director for the Centre for Phage Research and Professor of Microbiology at the University of LeicesterJames Ebdon Professor of Environmental Microbiology at the University of BrightonAnd Claas Kirchhelle Historian and Chargé de Recherche at the French National Institute of Health and Medical Research’s CERMES3 Unit in Paris.Producer: Simon TillotsonIn Our Time is a BBC Studios Audio ProductionReading list: James Ebdon, ‘Tackling sources of contamination in water: The age of phage’ (Microbiologist, Society for Applied Microbiology, Vol 20.1, 2022) Thomas Häusler, Viruses vs. Superbugs: A Solution to the Antibiotics Crisis?

Melvyn Bragg and guests discuss the work of the great French Impressionist Claude Monet (1840-1926) in London, initially in 1870 and then from 1899. He spent his first visit in poverty, escaping from war in France, while by the second he had become so commercially successful that he stayed at the Savoy Hotel. There, from his balcony, he began a series of almost a hundred paintings that captured the essence of this dynamic city at that time, with fog and smoke almost obscuring the bridges, boats and Houses of Parliament. The pollution was terrible for health but the diffraction through the sooty droplets offered an ever-changing light that captivated Monet, and he was to paint the Thames more than he did his water lilies or haystacks or Rouen Cathedral. On his return to France, Monet appeared to have a new confidence to explore an art that was more abstract than impressionist.WithKaren Serres Senior Curator of Paintings at the Courtauld Gallery, London Curator of the exhibition 'Monet and London.

Melvyn Bragg and guests discuss the doctrine of Karma as developed initially among Hindus, Jains and Buddhists in India from the first millennium BCE. Common to each is an idea, broadly, that you reap what you sow: how you act in this world has consequences either for your later life or your future lives, depending on your view of rebirth and transmigration. From this flow different ideas including those about free will, engagement with the world or disengagement, the nature of ethics and whether intention matters, and these ideas continue to develop today.With Monima Chadha Professor of Indian Philosophy and Tutorial Fellow at Lady Margaret Hall, University of OxfordJessica Frazier Lecturer in the Study of Religion at the University of Oxford and a Fellow of the Oxford Centre for Hindu StudiesAndKaren O’Brien-Kop Lecturer in Asian Religions at Kings College LondonProducer: Simon TillotsonIn Our Time is a BBC Studios Audio ProductionReading list:J.

Melvyn Bragg and guests discuss "The History of Tom Jones, A Foundling" (1749) by Henry Fielding (1707-1754), one of the most influential of the early English novels and a favourite of Dickens. Coleridge wrote that it had one of the 'three most perfect plots ever planned'. Fielding had made his name in the theatre with satirical plays that were so painful for their targets in government that, from then until the 1960s, plays required approval before being staged; seeking other ways to make a living, Fielding turned to law and to fiction. 'Tom Jones' is one of the great comic novels, with the tightness of a farce and the ambition of a Greek epic as told by the finest raconteur. While other authors might present Tom as a rake and a libertine, Fielding makes him the hero for his fundamental good nature, so offering a caution not to judge anyone too soon, if ever.With Judith Hawley Professor of 18th Century Literature at Royal Holloway, University of LondonHenry Power Professor of English Literature at the University of ExeterAndCharlotte Roberts Associate Professor of English Literature at University College LondonProducer: Simon TillotsonIn Our Time is a BBC Studios Audio ProductionReading list:Martin C.

This was the story of arguably the most important, strategically, of all the islands in the British Viking world, when the Earls controlled Shetland, Orkney and Caithness from which they could raid the Irish and British coasts, from Dublin round to Lindisfarne. The Saga combines myth with history, bringing to life the places on those islands where Vikings met, drank, made treaties, told stories, became saints, plotted and fought.With Judith Jesch Professor of Viking Studies at the University of NottinghamJane Harrison Archaeologist and Research Associate at Oxford and Newcastle UniversitiesAnd Alex Woolf Senior Lecturer in History at the University of St AndrewsProducer: Simon TillotsonIn Our Time is a BBC Studios Audio ProductionReading list:Theodore M.

Melvyn Bragg and guests discuss one of the canonical figures from the history of political thought. Marsilius of Padua (c1275 to c1343) wrote 'Defensor Pacis' (The Defender of the Peace) around 1324 when the Papacy, the Holy Roman Emperor and the French King were fighting over who had supreme power on Earth. In this work Marsilius argued that the people were the source of all power and they alone could elect a leader to act on their behalf; they could remove their leaders when they chose and, afterwards, could hold them to account for their actions. He appeared to favour an elected Holy Roman Emperor and he was clear that there were no grounds for the Papacy to have secular power, let alone gather taxes and wealth, and that clerics should return to the poverty of the Apostles. Protestants naturally found his work attractive in the 16th Century when breaking with Rome. In the 20th Century Marsilius has been seen as an early advocate for popular sovereignty and republican democracy, to the extent possible in his time.With Annabel Brett Professor of Political Thought and History at the University of CambridgeGeorge Garnett Professor of Medieval History and Fellow and Tutor at St Hugh’s College, University of OxfordAnd Serena Ferente Professor of Medieval History at the University of AmsterdamProducer: Simon Tillotson In Our Time is a BBC Sounds Audio ProductionReading list: Richard Bourke and Quentin Skinner (eds), Popular Sovereignty in Historical Perspective (Cambridge University Press, 2016), especially 'Popolo and law in Marsilius and the jurists' by Serena FerenteJ.

Melvyn Bragg and guests discuss the woman who, for almost fifty years, was the most powerful figure in the Chinese court. Cixi (1835-1908) started out at court as one of the Emperor's many concubines, yet was the only one who gave him a son to succeed him and who also possessed great political skill and ambition. When their son became emperor he was still a young child and Cixi ruled first through him and then, following his death, through another child emperor. This was a time of rapid change in China, when western powers and Japan humiliated the forces of the Qing empire time after time, and Cixi had the chance to push forward the modernising reforms the country needed to thrive. However, when she found those reforms conflicted with her own interests or those of the Qing dynasty, she was arguably obstructive or too slow to act and she has been personally blamed for some of those many humiliations even when the fault lay elsewhere.

Melvyn Bragg and guests discuss one of the most significant philosophers of the twentieth century, Philippa Foot (1920 - 2010). Her central question was, “Why be moral?” Drawing on Aristotle and Aquinas, Foot spent her life working through her instinct that there was something lacking in the prevailing philosophy of the 1950s and 1960s which held that values could only be subjective. Could there really be no objective response to the horrors of the concentration camps that she had seen on newsreels, no way of saying that such acts were morally wrong? Foot developed an ethics based on virtues, in which humans needed virtues to flourish as surely as plants needed light and water. While working through her ideas she explored applied ethics and the difference between doing something and letting it happen, an idea she illustrated with what became The Trolley Problem.With Anil Gomes Fellow and Tutor in Philosophy at Trinity College, University of OxfordSophie Grace Chappell Professor of Philosophy at the Open UniversityAnd Rachael Wiseman Reader in Philosophy at the University of LiverpoolProducer: Simon Tillotson In Our Time is a BBC Studios Audio ProductionReading list:Philippa Foot, Virtues and Vices (Oxford University Press, 1978)Philippa Foot, Moral Dilemmas (Oxford University Press, 2002)Philippa Foot, Natural Goodness (Oxford University Press, 2001)John Hacker-Wright, Philippa Foot's Moral Thought (Bloomsbury, 2013)Benjamin Lipscomb, The Women Are Up To Something (Oxford University Press, 2021)Clare Mac Cumhaill and Rachael Wiseman, Metaphysical Animals: How Four Women Brought Philosophy Back to Life (Chatto, 2022)Dan Russell (ed.), The Cambridge Companion to Virtue Ethics (Cambridge University Press), especially ‘Virtue Ethics in the Twentieth Century’ by Timothy (now Sophie Grace) Chappell

Melvyn Bragg and guests discuss 'the greatest poet of his age', Thomas Wyatt (1503 -1542), who brought the poetry of the Italian Renaissance into the English Tudor world, especially the sonnet, so preparing the way for Shakespeare and Donne. As an ambassador to Henry VIII and, allegedly, too close to Anne Boleyn, he experienced great privilege under intense scrutiny. Some of Wyatt's poems, such as They Flee From Me That Sometime Did Me Seek, are astonishingly fresh and conversational and yet he wrote them under the tightest constraints, when a syllable out of place could have condemned him to the Tower.

Melvyn Bragg and guests discuss the planet which is closest to our Sun. We see it as an evening or a morning star, close to where the Sun has just set or is about to rise, and observations of Mercury helped Copernicus understand that Earth and the other planets orbit the Sun, so displacing Earth from the centre of our system. In the 20th century, further observations of Mercury helped Einstein prove his general theory of relativity. For the last 50 years we have been sending missions there to reveal something of Mercury's secrets and how those relate to the wider universe, and he latest, BepiColombo, is out there in space now.

Melvyn Bragg and guests discuss one of the greatest European playwrights of the twentieth century. The aim of Bertolt Brecht (1898-1956) was to make the familiar ‘strange’: with plays such as Mother Courage and The Caucasian Chalk Circle he wanted his audience not to sit back but to engage, observe and discover the contradictions in life, and act on what they learnt. He developed this approach in turbulent times, from Weimar Germany to the rise of the Nazis, to exile in Scandinavia and America and then post-war life in East Berlin, and he has since inspired dramatists around the world.WithLaura Bradley Professor of German and Theatre at the University of EdinburghDavid Barnett Professor of Theatre at the University of YorkAnd Tom Kuhn Professor of Twentieth Century German Literature, Emeritus Fellow of St Hugh's College, University of OxfordProducer: Simon Tillotson In Our Time is a BBC Studios Audio productionReading list: David Barnett, Brecht in Practice: Theatre, Theory and Performance (Bloomsbury, 2014)David Barnett, A History of the Berliner Ensemble (Cambridge University Press, 2015)Laura Bradley and Karen Leeder (eds.), Brecht and the GDR: Politics, Culture, Posterity (Camden House, 2015)Laura Bradley, ‘Training the Audience: Brecht and the Art of Spectatorship’ (The Modern Language Review, 111, 2016)Bertolt Brecht (ed.

Melvyn Bragg and guests discuss Napoleon Bonaparte's temporary return to power in France in 1815, following his escape from exile on Elba . He arrived with fewer than a thousand men, yet three weeks later he had displaced Louis XVIII and taken charge of an army as large as any that the Allied Powers could muster individually. He saw that his best chance was to pick the Allies off one by one, starting with the Prussian and then the British/Allied armies in what is now Belgium. He appeared to be on the point of victory at Waterloo yet somehow it eluded him, and his plans were soon in tatters. His escape to America thwarted, he surrendered on 15th July and was exiled again but this time to Saint Helena. There he wrote his memoirs to help shape his legacy, while back in Europe there were still fears of his return.With Michael Rowe Reader in European History at Kings College LondonKatherine Astbury Professor of French Studies at the University of WarwickAndZack White Leverhulme Early Career Research Fellow at the University of PortsmouthProducer: Simon Tillotson In Our Time is a BBC Studios Audio production.Reading list:Katherine Astbury and Mark Philp (ed.), Napoleon's Hundred Days and the Politics of Legitimacy (Palgrave, 2018)Jeremy Black, The Battle of Waterloo: A New History (Icon Books, 2010)Michael Broers, Napoleon: The Decline and Fall of an Empire: 1811-1821 (Pegasus Books, 2022)Philip Dwyer, Citizen Emperor: Napoleon in power 1799-1815 (Bloomsbury, 2014)Charles J.

Melvyn Bragg and guests discuss Aristophanes' comedy in which the women of Athens and Sparta, led by Lysistrata, secure peace in the long-running war between them by staging a sex strike. To the men in the audience in 411BC, the idea that peace in the Peloponnesian War could be won so easily was ridiculous and the thought that their wives could have so much power over them was even more so. However Aristophanes' comedy also has the women seizing the treasure in the Acropolis that was meant to fund more fighting in an emergency, a fund the Athenians had recently had to draw on. They were in a perilous position and, much as they might laugh at Aristophanes' jokes, they knew there were real concerns about the actual cost of the war in terms of wealth and manpower.

Melvyn Bragg and guests discuss the Serbian-American inventor Nikola Tesla (1856-1943) and his role in the development of electrical systems towards the end of the nineteenth century. He made his name in New York in the contest over which current should flow into homes and factories in America. Some such as Edison backed direct current or DC while others such as Westinghouse backed alternating current or AC and Nikola Tesla’s invention of a motor that worked on AC swung it for the alternating system that went on to power the modern age. He ensured his reputation and ideas burnt brightly for the next decades, making him synonymous with the lone, genius inventor of the new science fiction.

Melvyn Bragg and guests discuss the Finnish epic poem that first appeared in print in 1835 in what was then the Grand Duchy of Finland, part of the Russian Empire and until recently part of Sweden. The compiler of this epic was a doctor, Elias Lönnrot (1802-1884), who had travelled the land to hear traditional poems about mythical heroes being sung in Finnish, the language of the peasantry, and writing them down in his own order to create this landmark work. In creating The Kalevala, Lönnrot helped the Finns realise they were a distinct people apart from Sweden and Russia, who deserved their own nation state and who came to demand independence, which they won in 1917.

Melvyn Bragg and guests discuss the last pagan ruler of the Roman Empire. Fifty years after Constantine the Great converted to Christianity and introduced a policy of tolerating the faith across the empire, Julian (c.331 - 363 AD) aimed to promote paganism instead, branding Constantine the worst of all his predecessors. Julian was a philosopher-emperor in the mould of Marcus Aurelius and was noted in his lifetime for his letters and his satires, and it was his surprising success as a general in his youth in Gaul that had propelled him to power barely twenty years after a rival had slaughtered his family. Julian's pagan mission and his life were brought to a sudden end while on campaign against the Sasanian Empire in the east, but he left so much written evidence of his ideas that he remains one of the most intriguing of all the Roman emperors and a hero to the humanists of the Enlightenment.

Melvyn Bragg and guests discuss the dance which, from when it reached Britain in the early nineteenth century, revolutionised the relationship between music, literature and people here for the next hundred years. While it may seem formal now, it was the informality and daring that drove its popularity, with couples holding each other as they spun round a room to new lighter music popularised by Johann Strauss, father and son, such as The Blue Danube.

Melvyn Bragg and guests discuss the revolt that broke out in 1871 in Algeria against French rule, spreading over hundreds of miles and countless towns and villages before being brutally suppressed. It began with the powerful Cheikh Mokrani and his family and was taken up by hundreds of thousands, becoming the last major revolt there before Algeria’s war of independence in 1954. In the wake of its swift suppression though came further waves of French migrants to settle on newly confiscated lands, themselves displaced by French defeat in Europe and the loss of Alsace-Lorraine, and their arrival only increased tensions. The Mokrani Revolt came to be seen as a watershed between earlier Ottoman rule and full national identity, an inspiration to nationalists in the 1950s.WithNatalya Benkhaled-Vince Associate Professor of the History of Modern France and the Francophone World, Fellow of University College, University of OxfordHannah-Louise Clark Senior Lecturer in Global Economic and Social History at the University of GlasgowAnd Jim House Senior Lecturer in French and Francophone History at the University of Leeds Producer: Simon Tillotson Reading list: Mahfoud Bennoune, The Making of Contemporary Algeria: 1830-1987 (Cambridge University Press, 1988)Julia Clancy-Smith, Rebel and Saint: Muslim Notables, Populist Protest, Colonial Encounters, Algeria and Tunisia 1800–1904 (University of California Press, 1994) Hannah-Louise Clark, ‘The Islamic Origins of the French Colonial Welfare State: Hospital Finance in Algeria’ (European Review of History, vol. 28, nos 5-6, 2021)Hannah-Louise Clark, ‘Of jinn theories and germ theories: translating microbes, bacteriological medicine, and Islamic law in Algeria’ (Osiris, vol. 36, 2021)Brock Cutler, Ecologies of Imperialism in Algeria (University of Nebraska Press, 2023) Didier Guignard, 1871: L’Algérie sous Séquestre (CNRS Éditions, 2023)Idir Hachi, ‘Histoire social de l’insurrection de 1871 et du procès de ses chefs (PhD diss., University of Aix-Marseille, 2017) Abdelhak Lahlou, Idir Hachi, Isabelle Guillaume, Amélie Gregório and Peter Dunwoodie, ‘L'insurrection kabyle de 1871’ (Etudes françaises volume 57, no 1, 2021)James McDougall, A History of Algeria (Cambridge University Press (2017)John Ruedy, Modern Algeria: The Origins and Development of a Nation (Indiana University Press, 2005, 2nd edition)Jennifer E Sessions, By Sword and Plow: France and the Conquest of Algeria (Cornell University Press, 2011)Samia Touati, ‘Lalla Fatma N’Soumer, 1830–1863: Spirituality, Resistance and Womanly Leadership in Colonial Algeria (Societies vol. 8, no. 4, 2018)Natalya Vince, Our Fighting Sisters: Nation, Memory and Gender in Algeria, 1954-2012 (Manchester University Press, 2015)

Melvyn Bragg and guests discuss the German physicist who, at the age of 23 and while still a student, effectively created quantum mechanics for which he later won the Nobel Prize. Werner Heisenberg made this breakthrough in a paper in 1925 when, rather than starting with an idea of where atomic particles were at any one time, he worked backwards from what he observed of atoms and their particles and the light they emitted, doing away with the idea of their continuous orbit of the nucleus and replacing this with equations. This was momentous and from this flowed what’s known as his Uncertainty Principle, the idea that, for example, you can accurately measure the position of an atomic particle or its momentum, but not both.With Fay Dowker Professor of Theoretical Physics at Imperial College LondonHarry Cliff Research Fellow in Particle Physics at the University of CambridgeAnd Frank Close Professor Emeritus of Theoretical Physics and Fellow Emeritus at Exeter College at the University of OxfordProducer: Simon TillotsonReading list:Philip Ball, Beyond Weird: Why Everything You Thought You Knew about Quantum Physics Is Different (Vintage, 2018)John Bell, ‘Against 'measurement'’ (Physics World, Vol 3, No 8, 1990)Mara Beller, Quantum Dialogue: The Making of a Revolution (University of Chicago Press, 2001)David C.

Melvyn Bragg and guests discuss the infamous assault of an army of the Holy Roman Emperor on the city of Rome in 1527. The troops soon broke through the walls of this holy city and, with their leader shot dead early on, they brought death and destruction to the city on an epic scale. Later writers compared it to the fall of Carthage or Jerusalem and soon the mass murder, torture, rape and looting were followed by disease which was worsened by starvation and opened graves. It has been called the end of the High Renaissance, a conflict between north and south, between Lutherans and Catholics, and a fulfilment of prophecy of divine vengeance and, perhaps more persuasively, a consequence of military leaders not feeding or paying their soldiers other than by looting.

Melvyn Bragg and guests discuss Lewis Carroll's book which first appeared in print in 1865 with illustrations by John Tenniel. It has since become one of the best known works in English, captivating readers who follow young Alice as she chases a white rabbit, pink eyed, in a waistcoat with pocket watch, down a rabbit hole that becomes a well and into wonderland. There she meets the Cheshire Cat, the Hatter, the March Hare, the Mock Turtle and more, all the while growing smaller and larger, finally outgrowing everyone at the trial of Who Stole the Tarts from the Queen of Hearts and exclaiming 'Who cares for you? You’re nothing but a pack of cards!'WithFranziska Kohlt Leverhulme Research Fellow in the History of Science at the University of Leeds and the Inaugural Carrollian Fellow of the University of Southern CaliforniaKiera Vaclavik Professor of Children’s Literature and Childhood Culture at Queen Mary, University of LondonAndRobert Douglas-Fairhurst Professor of English Literature at Magdalen College, University of OxfordProducer: Simon TillotsonReading list:Kate Bailey and Simon Sladen (eds), Alice: Curiouser and Curiouser (V&A Publishing, 2021)Gillian Beer, Alice in Space: The Sideways Victorian World of Lewis Carroll (University of Chicago Press, 2016)Will Brooker, Alice's Adventures: Lewis Carroll and Alice in Popular Culture (Continuum, 2004)Humphrey Carpenter, Secret Gardens: A Study of the Golden Age of Children’s Literature (first published 1985; Faber and Faber, 2009)Lewis Carroll (introduced by Martin Gardner), The Annotated Alice: The Definitive Edition, (W.

Melvyn Bragg and guests discuss some of the chemical signals coursing through our bodies throughout our lives, produced in separate areas and spreading via the bloodstream. We call these 'hormones' and we produce more than 80 of them of which the best known are arguably oestrogen, testosterone, adrenalin, insulin and cortisol. On the whole hormones operate without us being immediately conscious of them as their goal is homeostasis, maintaining the levels of everything in the body as required without us having to think about them first. Their actions are vital for our health and wellbeing and influence many different aspects of the way our bodies work.WithSadaf Farooqi Professor of Metabolism and Medicine at the University of CambridgeRebecca Reynolds Professor of Metabolic Medicine at the University of EdinburghAndAndrew Bicknell Associate Professor in the School of Biological Sciences at the University of ReadingProduced by Victoria BrignellReading list:Rachel Carson, Silent Spring (first published 1962; Penguin Classics, 2000)Stephen Nussey and Saffron Whitehead, Endocrinology: An Integrated Approach (BIOS Scientific Publishers; 2001)Aylinr Y.

Melvyn Bragg and guests discuss the Hanseatic League or Hansa which dominated North European trade in the medieval period. With a trading network that stretched from Iceland to Novgorod via London and Bruges, these German-speaking Hansa merchants benefitted from tax exemptions and monopolies. Over time, the Hansa became immensely influential as rulers felt the need to treat it well. Kings and princes sometimes relied on loans from the Hansa to finance their wars and an embargo by the Hansa could lead to famine. Eventually, though, the Hansa went into decline with the rise in the nation state’s power, greater competition from other merchants and the development of trade across the Atlantic.

Melvyn Bragg and guests discuss the idea that some kind of consciousness is present not just in our human brains but throughout the universe, right down to cells or even electrons. This is panpsychism and its proponents argue it offers a compelling alternative to those who say we are nothing but matter, like machines, and to those who say we are both matter and something else we might call soul. It is a third way. Critics argue panpsychism is implausible, an example of how not to approach this problem, yet interest has been growing widely in recent decades partly for the idea itself and partly in the broader context of understanding how consciousness arises.WithTim Crane Professor of Philosophy and Pro-Rector at the Central European University Director of Research, FWF Cluster of Excellence, Knowledge in CrisisJoanna Leidenhag, Associate Professor in Theology and Philosophy at the University of LeedsAnd Philip Goff Professor of Philosophy at Durham UniversityProducer: Simon TillotsonReading list:Anthony Freeman (ed.), Consciousness and Its Place in Nature: Does Physicalism Entail Panpsychism?

Melvyn Bragg and guests discuss the woman who inspired one of the best known artefacts from ancient Egypt. The Bust of Nefertiti is multicoloured and symmetrical, about 49cm/18" high and, despite the missing left eye, still holds the gaze of onlookers below its tall, blue, flat topped headdress. Its discovery in 1912 in Amarna was kept quiet at first but its display in Berlin in the 1920s caused a sensation, with replicas sent out across the world. Ever since, as with Tutankhamun perhaps, the concrete facts about Nefertiti herself have barely kept up with the theories, the legends and the speculation, reinvigorated with each new discovery.

Melvyn Bragg and guests discuss Nicolas de Condorcet (1743-94), known as the Last of the Philosophes, the intellectuals in the French Enlightenment who sought to apply their learning to solving the problems of their world. He became a passionate believer in the progress of society, an advocate for equal rights for women and the abolition of the slave trade and for representative government. The French Revolution gave him a chance to advance those ideas and, while the Terror brought his life to an end, his wife Sophie de Grouchy 91764-1822) ensured his influence into the next century and beyond.

Melvyn Bragg and guests discuss one of Shakespeare’s great comedies, which plays in the space between marriage, love and desire. By convention a wedding means a happy ending and here there are three, but neither Orsino nor Viola, Olivia nor Sebastian know much of each other’s true character and even the identities of the twins Viola and Sebastian have only just been revealed to their spouses to be. These twins gain some financial security but it is unclear what precisely the older Orsino and Olivia find enduringly attractive in the adolescent objects of their love. Meanwhile their hopes and illusions are framed by the fury of Malvolio, tricked into trusting his mistress Olivia loved him and who swears an undefined revenge on all those who mocked him.With Pascale Aebischer Professor of Shakespeare and Early Modern Performance Studies at the University of ExeterMichael Dobson Professor of Shakespeare Studies and Director of the Shakespeare Institute at the University of BirminghamAnd Emma Smith Professor of Shakespeare Studies at Hertford College, University of OxfordProduced by Simon Tillotson, Victoria Brignell and Luke MulhallReading list:C.L.

Melvyn Bragg and guests discuss the Dutch artist famous for starry nights and sunflowers, self portraits and simple chairs. These are images known the world over, and Vincent van Gogh (1853-1890) painted them and around 900 others in the last decade of his short, brilliant life and, famously, in that lifetime he made only one recorded sale. Yet within a few decades after his death these extraordinary works, with all their colour and life, became the most desirable of all modern art, propelled in part by the story of Vincent van Gogh's struggle with mental health.With Christopher Riopelle The Neil Westreich Curator of Post 1800 Paintings at the National GalleryMartin Bailey A leading Van Gogh specialist and correspondent for The Art NewspaperAnd Frances Fowle Professor of Nineteenth Century Art at the University of Edinburgh and Senior Curator at National Galleries ScotlandProducer: Simon TillotsonReading list: Martin Bailey, Living with Vincent Van Gogh: The Homes and Landscapes that shared the Artist (White Lion Publishing, 2019)Martin Bailey, Studio of the South: Van Gogh in Provence (Frances Lincoln, 2021)Martin Bailey, Van Gogh’s Finale: Auvers and the Artist’s Rise to Fame (Frances Lincoln, 2021)Nienke Bakker and Ella Hendriks, Van Gogh and the Sunflowers: A Masterpiece Examined (Van Gogh Museum, 2019)Nienke Bakker, Emmanuel Coquery, Teio Meedendorp and Louis van Tilborgh (eds), Van Gogh in Auvers-sur-Oise: His Final Months (Thames & Hudson, 2023)Frances Fowle, Van Gogh's Twin: The Scottish Art Dealer Alexander Reid, 1854-1928 (National Galleries of Scotland, 2010) Bregje Gerritse, The Potato Eaters: Van Gogh’s First Masterpiece (Van Gogh Museum, 2021)Steven Naifeh and Gregory White Smith, Van Gogh: The Life (Random House, 2012)Leo Jansen, Hans Luijten and Nienke Bakker (eds), Vincent van Gogh: The Letters: The Complete Illustrated and Annotated Edition (Thames and Hudson Ltd, 2009)Leo Jansen, Hans Luijten and Nienke Bakker (eds), Vincent van Gogh, A Life in Letters (Thames and Hudson Ltd, 2020)Hans Luitjen, Jo van Gogh Bonger: The Woman who Made Vincent Famous Bloomsbury, 2022Louis van Tilborgh, Martin Bailey, Karen Serres (ed.), Van Gogh Self-Portraits (Courtauld Institute, 2022)Ingo F.

Melvyn Bragg and guests discuss the Roman emperor Tiberius. When he was born in 42BC, there was little prospect of him ever becoming Emperor of Rome. Firstly, Rome was still a Republic and there had not yet been any Emperor so that had to change and, secondly, when his stepfather Augustus became Emperor there was no precedent for who should succeed him, if anyone. It somehow fell to Tiberius to develop this Roman imperial project and by some accounts he did this well, while to others his reign was marked by cruelty and paranoia inviting comparison with Nero.WithMatthew Nicholls Senior Tutor at St. John’s College, University of OxfordShushma Malik Assistant Professor of Classics and Onassis Classics Fellow at Newnham College at the University of CambridgeAnd Catherine Steel Professor of Classics at the University of GlasgowProducer: Simon TillotsonReading list:Edward Champlin, ‘Tiberius the Wise’ (Historia: Zeitschrift für Alte Geschichte, 57.4, 2008)Alison E.

Melvyn Bragg and guests discuss one of the most influential theologians of the twentieth century. Karl Barth (1886 - 1968) rejected the liberal theology of his time which, he argued, used the Bible and religion to help humans understand themselves rather than prepare them to open themselves to divine revelation. Barth's aim was to put God and especially Christ at the centre of Christianity. He was alarmed by what he saw as the dangers in a natural theology where God might be found in a rainbow or an opera by Wagner; for if you were open to finding God in German culture, you could also be open to accepting Hitler as God’s gift as many Germans did.

Melvyn Bragg and guests discuss Poe (1809-1849), the American author who is famous for his Gothic tales of horror, madness and the dark interiors of the mind, such as The Fall of the House of Usher and The Tell-Tale Heart. As well as tapping at our deepest fears in poems such as The Raven, Poe pioneered detective fiction with his character C. Auguste Dupin in The Murders in the Rue Morgue. After his early death, a rival rushed out a biography to try to destroy Poe's reputation but he has only become more famous over the years as a cultural icon as well as an author.WithBridget Bennett Professor of American Literature and Culture at the University of LeedsErin Forbes Senior Lecturer in 19th-century African American and US Literature at the University of BristolAndTom Wright Reader in Rhetoric at the University of SussexProducer: Simon TillotsonReading list: Peter Ackroyd, Poe: A Life Cut Short (Vintage, 2009)Amy Branam Armiento and Travis Montgomery (eds.), Poe and Women: Recognition and Revision (Lehigh University Press, 2023)Joan Dayan, Fables of Mind: An Inquiry into Poe's Fiction (Oxford University Press, 1987)Erin Forbes, ‘Edgar Allan Poe in the Great Dismal Swamp’ (Modern Philology, 2016)Kevin J.

Melvyn Bragg and guests discuss Marguerite, Queen of Navarre (1492 – 1549), author of the Heptaméron, a major literary landmark in the French Renaissance. Published after her death, The Heptaméron features 72 short stories, many of which explore relations between the sexes. However, Marguerite’s life was more eventful than that of many writers. Born into the French nobility, she found herself the sister of the French king when her brother Francis I came to the throne in 1515. At a time of growing religious change, Marguerite was a leading exponent of reform in the Catholic Church and translated an early work of Martin Luther into French. As the Reformation progressed, she was not afraid to take risks to protect other reformers.With Sara Barker Associate Professor of Early Modern History and Director of the Centre for the Comparative History of Print at the University of LeedsEmily Butterworth Professor of Early Modern French at King’s College LondonAnd Emma Herdman Lecturer in French at the University of St AndrewsProducer: Simon TillotsonReading list: Giovanni Boccaccio (trans.

Melvyn Bragg and guests discuss the most influential work of Thorstein Veblen (1857-1929). In 1899, during America’s Gilded Age, Veblen wrote The Theory of the Leisure Class as a reminder that all that glisters is not gold. He picked on traits of the waning landed class of Americans and showed how the new moneyed class was adopting these in ways that led to greater waste throughout society. He called these conspicuous leisure and conspicuous consumption and he developed a critique of a system that favoured profits for owners without regard to social good. The Theory of the Leisure Class was a best seller and funded Veblen for the rest of his life, and his ideas influenced the New Deal of the 1930s. Since then, an item that becomes more desirable as it becomes more expensive is known as a Veblen good.

Melvyn Bragg and guests discuss the North African privateers who, until their demise in the nineteenth century, were a source of great pride and wealth in their home ports, where they sold the people and goods they’d seized from Christian European ships and coastal towns. Nominally, these corsairs were from Algiers, Tunis or Tripoli, outreaches of the Ottoman empire, or Salé in neighbouring Morocco, but often their Turkish or Arabic names concealed their European birth. Murad Reis the Younger, for example, who sacked Baltimore in 1631, was the Dutchman Jan Janszoon who also had a base on Lundy in the Bristol Channel. While the European crowns negotiated treaties to try to manage relations with the corsairs, they commonly viewed these sailors as pirates who were barely tolerated and, as soon as France, Britain, Spain and later America developed enough sea power, their ships and bases were destroyed.

Melvyn Bragg and guests discuss Aristotle's ideas on what happiness means and how to live a good life. Aristotle (384-322BC) explored these almost two and a half thousand years ago in what became known as his Nicomachean Ethics. His audience then were the elite in Athens as, he argued, if they knew how to live their lives well then they could better rule the lives of others. While circumstances and values have changed across the centuries, Aristotle's approach to answering those questions has fascinated philosophers ever since and continues to do so.With Angie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldRoger Crisp Director of the Oxford Uehiro Centre for Practical Ethics, Professor of Moral Philosophy and Tutor in Philosophy at St Anne’s College, University of OxfordAnd Sophia Connell Senior Lecturer in Philosophy at Birkbeck, University of LondonProducer: Simon TillotsonReading list:J.L.

Melvyn Bragg and guests discuss Emile Zola's greatest literary success, his thirteenth novel in a series exploring the extended Rougon-Macquart family. The relative here is Etienne Lantier, already known to Zola’s readers as one of the blighted branch of the family tree and his story is set in Northern France. It opens with Etienne trudging towards a coalmine at night seeking work, and soon he is caught up in a bleak world in which starving families struggle and then strike, as they try to hold on to the last scraps of their humanity and the hope of change.WithSusan Harrow Ashley Watkins Chair of French at the University of BristolKate Griffiths Professor in French and Translation at Cardiff UniversityAndEdmund Birch Lecturer in French Literature and Director of Studies at Churchill College & Selwyn College, University of CambridgeProducer: Simon TillotsonReading list:David Baguley, Naturalist Fiction: The Entropic Vision (Cambridge University Press, 1990)William Burgwinkle, Nicholas Hammond and Emma Wilson (eds.), The Cambridge History of French Literature (Cambridge University Press, 2011), particularly ‘Naturalism’ by Nicholas WhiteKate Griffiths, Emile Zola and the Artistry of Adaptation (Legenda, 2009)Kate Griffiths and Andrew Watts, Adapting Nineteenth-Century France: Literature in Film, Theatre, Television, Radio, and Print (University of Wales Press, 2013) Anna Gural-Migdal and Robert Singer (eds.), Zola and Film: Essays in the Art of Adaptation (McFarland & Co., 2005)Susan Harrow, Zola, The Body Modern: Pressures and Prospects of Representation (Legenda, 2010)F.

Melvyn Bragg and guests discuss the anchoress and mystic who, in the late fourteenth century, wrote about her visions of Christ suffering, in a work since known as Revelations of Divine Love. She is probably the first named woman writer in English, even if questions about her name and life remain open. Her account is an exploration of the meaning of her visions and is vivid and bold, both in its imagery and theology. From her confined cell in a Norwich parish church, in a land beset with plague, she dealt with the nature of sin and with the feminine side of God, and shared the message she received that God is love and, famously, that all shall be well and all manner of things shall be well.WithKatherine Lewis Professor of Medieval History at the University of HuddersfieldPhilip Sheldrake Professor of Christian Spirituality at the Oblate School of Theology, Texas and Senior Research Associate of the Von Hugel Institute, University of CambridgeAnd Laura Kalas Senior Lecturer in Medieval English Literature at Swansea UniversityProducer: Simon TillotsonReading list:John H.

Melvyn Bragg and guests discuss Alexander Hamilton, James Madison and John Jay's essays written in 1787/8 in support of the new US Constitution. They published these anonymously in New York as 'Publius' but, when it became known that Hamilton and Madison were the main authors, the essays took on a new significance for all states. As those two men played a major part in drafting the Constitution itself, their essays have since informed debate over what the authors of that Constitution truly intended. To some, the essays have proved to be America’s greatest contribution to political thought.WithFrank Cogliano Professor of American History at the University of Edinburgh and Interim Saunders Director of the International Centre for Jefferson Studies at MonticelloKathleen Burk Professor Emerita of Modern and Contemporary History at University College LondonAndNicholas Guyatt Professor of North American History at the University of CambridgeProducer: Simon TillotsonReading list: Bernard Bailyn, To Begin the World Anew: The Genius and Ambiguities of the American Founders (Knopf, 2003)Mary Sarah Bilder, Madison’s Hand: Revising the Constitutional Convention (Harvard University Press, 2015)Noah Feldman, The Three Lives of James Madison: Genius, Partisan, President (Random House, 2017)Jonathan Gienapp, The Second Creation: Fixing the American Constitution in the Founding Era (Harvard University Press, 2018)Alexander Hamilton, John Jay, James Madison (eds.

Melvyn Bragg and guests discuss the tiny drifting organisms in the oceans that sustain the food chain for all the lifeforms in the water and so for the billions of people who, in turn, depend on the seas for their diet. In Earth's development, the plant-like ones among them, the phytoplankton, produced so much oxygen through photosynthesis that around half the oxygen we breathe today originated there. And each day as the sun rises, the animal ones, the zooplankton, sink to the depths of the seas to avoid predators in such density that they appear on ship sonars like a new seabed, only to rise again at night in the largest migration of life on this planet.WithCarol Robinson Professor of Marine Sciences at the University of East AngliaAbigail McQuatters-Gollop Associate Professor of Marine Conservation at the University of PlymouthAndChristopher Lowe Lecturer in Marine Biology at Swansea UniversityProducer: Simon TillotsonReading list: Juli Berwald, Spineless: The Science of Jellyfish and the Art of Growing a Backbone (Riverhead Books, 2018)Sir Alister Hardy, The Open Sea: The World of Plankton (first published 1959; Collins New Naturalist Library, 2009) Richard Kirby, Ocean Drifters: A Secret World Beneath the Waves (Studio Cactus Ltd, 2010)Robert Kunzig, Mapping the Deep: The Extraordinary Story of Ocean Science (Sort Of Books, 2000)Christian Sardet, Plankton: Wonders of the Drifting World (University of Chicago Press, 2015) Helen Scales, The Brilliant Abyss: True Tales of Exploring the Deep Sea, Discovering Hidden Life and Selling the Seabed (Bloomsbury Sigma, 2022)

In an extended version of the programme that was broadcast, Melvyn Bragg and guests discuss the influential book John Maynard Keynes wrote in 1919 after he resigned in protest from his role at the Paris Peace Conference. There the victors of World War One were deciding the fate of the defeated, especially Germany and Austria-Hungary, and Keynes wanted the world to know his view that the economic consequences would be disastrous for all. Soon Germany used his book to support their claim that the Treaty was grossly unfair, a sentiment that fed into British appeasement in the 1930s and has since prompted debate over whether Keynes had only warned of disaster or somehow contributed to it.WithMargaret MacMillan Emeritus Professor of International History at the University of OxfordMichael Cox Emeritus Professor of International Relations at the London School of Economics and Founding Director of LSE IDEASAnd Patricia Clavin Professor of Modern History at the University of OxfordProducer: Simon TillotsonReading list:Manfred F.

In the 1000th edition of In Our Time, Melvyn Bragg and guests discuss arguably the most celebrated film of the Swedish director Ingmar Bergman (1918-2007). It begins with an image that, once seen, stays with you for the rest of your life: the figure of Death playing chess with a Crusader on the rocky Swedish shore. The release of this film in 1957 brought Bergman fame around the world. We see Antonius Block, the Crusader, realising he can’t beat Death but wanting to prolong this final game for one last act, without yet knowing what that act might be. As he goes on a journey through a plague ridden world, his meeting with a family of jesters and their baby offers him some kind of epiphany.

To mark his 1000th episode of In Our Time, Melvyn Bragg talks to Mishal Husain for Radio 4's Today programme.

Melvyn Bragg and guests discuss the man who, in 1905, produced several papers that were to change the world of physics and whose name went on to become a byword for genius. This was Albert Einstein, then still a technical expert at a Swiss patent office, and that year of 1905 became known as his annus mirabilis ('miraculous year'). While Einstein came from outside the academic world, some such as Max Planck championed his theory of special relativity, his principle of mass-energy equivalence that followed, and his explanations of Brownian Motion and the photoelectric effect. Yet it was not until 1919, when a solar eclipse proved his theory that gravity would bend light, that Einstein became an international celebrity and developed into an almost mythical figure.With Richard Staley Professor in History and Philosophy of Science at the University of Cambridge and Professor in History of Science at the University of CopenhagenDiana Kormos Buchwald Robert M.

Jupiter is the largest planet in our solar system, and it’s hard to imagine a world more alien and different from Earth. It’s known as a Gas Giant, and its diameter is eleven times the size of Earth’s: our planet would fit inside it one thousand three hundred times. But its mass is only three hundred and twenty times greater, suggesting that although Jupiter is much bigger than Earth, the stuff it’s made of is much, much lighter. When you look at it through a powerful telescope you see a mass of colourful bands and stripes: these are the tops of ferocious weather systems that tear around the planet, including the great Red Spot, probably the longest-lasting storm in the solar system. Jupiter is so enormous that it’s thought to have played an essential role in the distribution of matter as the solar system formed – and it plays an important role in hoovering up astral debris that might otherwise rain down on Earth. It’s almost a mini solar system in its own right, with 95 moons orbiting around it. At least two of these are places life might possibly be found.

In 1956 Oxford University awarded an honorary degree to the former US president Harry S. Truman for his role in ending the Second World War. One philosopher, Elizabeth Anscombe (1919 – 2001), objected strongly. She argued that although dropping nuclear bombs on Hiroshima and Nagasaki may have ended the fighting, it amounted to the murder of tens of thousands of innocent civilians. It was therefore an irredeemably immoral act. And there was something fundamentally wrong with a moral philosophy that didn’t see that. This was the starting point for a body of work that changed the terms in which philosophers discussed moral and ethical questions in the second half of the twentieth century. A leading student of the philosopher Ludwig Wittgenstein, Anscombe combined his insights with rejuvenated interpretations of Aristotle and Thomas Aquinas that made these ancient figures speak to modern issues and concerns. Anscombe was also instrumental in making action, and the question of what it means to intend to do something, a leading area of philosophical work.

Death in Venice is Thomas Mann’s most famous – and infamous - novella. Published in 1912, it’s about the fall of the repressed writer Gustav von Aschenbach, when his supposedly objective appreciation of a young boy’s beauty becomes sexual obsession. It explores the link between creativity and self-destruction, and by the end Aschenbach’s humiliation is complete, dying on a deckchair in the act of ogling. Aschenbach's stalking of the boy and dreaming of pederasty can appal modern readers, even more than Mann expected.

Sophocles’ play Oedipus Rex begins with a warning: the murderer of the old king of Thebes, Laius, has never been identified or caught, and he’s still at large in the city. Oedipus is the current king of Thebes, and he sets out to solve the crime. His investigations lead to a devastating conclusion. Not only is Oedipus himself the killer, but Laius was his father, and Laius’ wife Jocasta, who Oedipus has married, is his mother. Oedipus Rex was composed during the golden age of Athens, in the 5th century BC. Sophocles probably wrote it to explore the dynamics of power in an undemocratic society. It has unsettled audiences from the very start: it is the only one of Sophocles’ plays that didn’t win first prize at Athens’ annual drama festival. But it’s had exceptionally good write-ups from the critics: Aristotle called it the greatest example of the dramatic arts. Freud believed it laid bare the deepest structures of human desire.

Melvyn Bragg and guests discuss the power-packs within cells in all complex life on Earth. Inside each cell of every complex organism there are structures known as mitochondria. The 19th century scientists who first observed them thought they were bacteria which had somehow invaded the cells they were studying. We now understand that mitochondria take components from the food we eat and convert them into energy. Mitochondria are essential for complex life, but as the components that run our metabolisms they can also be responsible for a range of diseases – and they probably play a role in how we age. The DNA in mitochondria is only passed down the maternal line. This means it can be used to trace population movements deep into human history, even back to an ancestor we all share: mitochondrial Eve.

In 1661 the 23 year-old French king Louis the XIV had been on the throne for 18 years when his chief minister, Cardinal Mazarin, died. Louis is reported to have said to his ministers, “It is now time that I govern my affairs myself. You will assist me with your counsels when I ask for them [but] I order you to seal no orders except by my command… I order you not to sign anything, not even a passport, without my command, and to render account to me personally each day”So began the personal rule of Louis XIV, which lasted a further 54 years until his death in 1715. From his newly-built palace at Versailles, Louis was able to project an image of himself as the centre of gravity around which all of France revolved: it’s no accident that he became known as the Sun King. He centralized power to the extent he was able to say ‘L’etat c’est moi’: I am the state. Under his rule France became the leading diplomatic, military and cultural power in Europe.WithCatriona Seth Marshal Foch Professor of French Literature at the University of OxfordGuy Rowlands Professor of Early Modern History at the University of St AndrewsandPenny Roberts Professor of Early Modern History at the University of WarwickProducer: Luke Mulhall

In the year 29 BC the great Roman poet Virgil published these lines: Blessed is he who has succeeded in learning the laws of nature’s working, has cast beneath his feet all fear and fate’s implacable decree, and the howl of insatiable Death. But happy too is he who knows the rural gods…They’re from his poem the Georgics, a detailed account of farming life in the Italy of the time. ‘Georgics’ means ‘agricultural things’, and it’s often been read as a farming manual. But it was written at a moment when the Roman world was emerging from a period of civil war, and questions of land ownership and management were heavily contested. It’s also a philosophical reflection on humanity’s relationship with the natural world, the ravages of time, and the politics of Virgil’s day. It’s exerted a profound influence on European writing about agriculture and rural life, and has much to offer environmental thinking today.

Melvyn Bragg and guests discuss the Christian uprising in Japan and its profound and long-term consequences. In the 1630s, Japan was ruled by the Tokagawa Shoguns, a military dynasty who, 30 years earlier, had unified the country, ending around two centuries of civil war. In 1637 a rebellion broke out in the province of Shimabara, in the south of the country. It was a peasants’ revolt, following years of bad harvests in which the local lord had refused to lower taxes. Many of the rebels were Christians, and they fought under a Christian banner. The central government’s response was merciless. They met the rebels with an army of 150 000 men, possibly the largest force assembled anywhere in the world during the Early Modern period. Once the rebellion had been suppressed, the Shogun enforced a ban on Christianity and expelled nearly all foreigners from the country. Japan remained more or less completely sealed off from the rest of the world for the next 250 years.

Melvyn Bragg and guests discuss the revelatory collection of Biblical texts, legal documents, community rules and literary writings. In 1946 a Bedouin shepherd boy was looking for a goat he’d lost in the hills above the Dead Sea. He threw a rock into a cave and heard a hollow sound. He’d hit a ceramic jar containing an ancient manuscript. This was the first of the Dead Sea Scrolls, a collection of about a thousand texts dating from around 250 BC to AD 68. It is the most substantial first hand evidence we have for the beliefs and practices of Judaism in and around the lifetime of Jesus. The Dead Sea Scrolls have transformed our understanding of how the texts that make up the Hebrew Bible were edited and collected. They also offer a tantalising window onto the world from which Christianity eventually emerged.

Melvyn Bragg and guests discuss the highly influential American poet Walt Whitman. In 1855 Whitman was working as a printer, journalist and property developer when he published his first collection of poetry. It began:I celebrate myself, And what I assume you shall assume For every atom belonging to me as good belongs to you. The book was called Leaves of Grass. In it, Whitman set out to break away from European literary forms and traditions. Using long lines written in free verse, he developed a poetry meant to express a distinctively American outlook. Leaves of Grass is full of verse that celebrates both the sovereign individual, and the deep fellowship between individuals. Its optimism about the American experience was challenged by the Civil War and its aftermath, but Whitman emerged as a celebrity and a key figure in the development of American culture.

Melvyn Bragg and guests discuss the life, ideas and legacy of the pioneering Swedish botanist Carl Linnaeus (1707 – 1778). The philosopher Jean-Jacques Rousseau once wrote: "Tell him I know no greater man on earth". The son of a parson, Linnaeus grew up in an impoverished part of Sweden but managed to gain a place at university. He went on to transform biology by making two major innovations. He devised a simpler method of naming species and he developed a new system for classifying plants and animals, a system that became known as the Linnaean hierarchy. He was also one of the first people to grow a banana in Europe.

Melvyn Bragg and guests discuss the brutal events of 26 August 1346, when the armies of France and England met in a funnel-shaped valley outside the town of Crécy in northern France. Although the French, led by Philip VI, massively outnumbered the English, under the command of Edward III, the English won the battle, and French casualties were huge. The English victory is often attributed to the success of their longbowmen against the heavy cavalry of the French. The Battle of Crécy was the result of years of simmering tension between Edward III and Philip VI, and it led to decades of further conflict between England and France, a conflict that came to be known as the Hundred Years War.

Melvyn Bragg and guests discuss the Danish prince who became a very effective King of England in 1016. Cnut inherited a kingdom in a sorry state. The north and east coast had been harried by Viking raiders, and his predecessor King Æthelred II had struggled to maintain order amongst the Anglo-Saxon nobility too. Cnut proved to be skilful ruler. Not only did he bring stability and order to the kingdom, he exported the Anglo-Saxon style of centralised government to Denmark. Under Cnut, England became the cosmopolitan centre of a multi-national North Atlantic Empire, and a major player in European politics.

Melvyn Bragg and guests discuss Virginia Woolf's highly influential essay on women and literature, which considers both literary history and future opportunity. In 1928 Woolf gave two lectures at Cambridge University about women and fiction. In front of an audience at Newnham College, she delivered the following words: “All I could do was offer you an opinion upon one minor point - a woman must have money and a room of her own if she is to write fiction; and that, as you will see, leaves the great problem of the true nature of woman and the true nature of fiction unsolved”. These lectures formed the basis of a book she published the following year, and Woolf chose A Room Of One’s Own for its title. It is a text that set the scene for the study of women’s writing for the rest of the 20th century. Arguably, it initiated the discipline of women’s history too.

Melvyn Bragg and guests discuss Solon, who was elected archon or chief magistrate of Athens in 594 BC: some see him as the father of Athenian democracy. In the first years of the 6th century BC, the city state of Athens was in crisis. The lower orders of society were ravaged by debt, to the point where some were being forced into slavery. An oppressive law code mandated the death penalty for everything from murder to petty theft. There was a real danger that the city could fall into either tyranny or civil war.Solon instituted a programme of reforms that transformed Athens’ political and legal systems, its society and economy, so that later generations referred to him as Solon the Lawgiver.

Melvyn Bragg and guests discuss how, between the 16th and 18th centuries, Europe was dominated by an economic way of thinking called mercantilism. The key idea was that exports should be as high as possible and imports minimised. For more than 300 years, almost every ruler and political thinker was a mercantilist. Eventually, economists including Adam Smith, in his ground-breaking work of 1776 The Wealth of Nations, declared that mercantilism was a flawed concept and it became discredited. However, a mercantilist economic approach can still be found in modern times and today’s politicians sometimes still use rhetoric related to mercantilism.

Melvyn Bragg and guests discuss the Ramayana, the ancient Hindu epic which is regarded as one of the greatest works of world literature. Its importance in Indian culture has been compared to that of the Iliad and Odyssey in the West, and it’s still seen as a sacred text by Hindus today. Written in Sanskrit, it tells the story of the legendary prince and princess Rama and Sita, and the many challenges, misfortunes and choices that they face. About 24,000 verses long, the Ramayana is also one of the longest ancient epics. It’s a text that’s been hugely influential and it continues to be popular in India and elsewhere in Asia.

Melvyn Bragg and guests discuss megaliths - huge stones placed in the landscape, often visually striking and highly prominent. Such stone monuments in Britain and Ireland mostly date from the Neolithic period, and the most ancient are up to 6,000 years old. In recent decades, scientific advances have enabled archaeologists to learn a large amount about megalithic structures and the people who built them, but much about these stones remains unknown and mysterious.

Paul Erdős (1913 – 1996) is one of the most celebrated mathematicians of the 20th century. During his long career, he made a number of impressive advances in our understanding of maths and developed whole new fields in the subject. He was born into a Jewish family in Hungary just before the outbreak of World War I, and his life was shaped by the rise of fascism in Europe, anti-Semitism and the Cold War. His reputation for mathematical problem solving is unrivalled and he was extraordinarily prolific. He produced more than 1,500 papers and collaborated with around 500 other academics. He also had an unconventional lifestyle. Instead of having a long-term post at one university, he spent much of his life travelling around visiting other mathematicians, often staying for just a few days.

In 1957 Stevie Smith published a poetry collection called Not Waving But Drowning – and its title poem gave us a phrase which has entered the language. Its success has overshadowed her wider work as the author of more than half a dozen collections of poetry and three novels, mostly written while she worked as a secretary. Her poems, printed with her pen and ink sketches, can seem simple and comical, but often beneath the surface lurk themes of melancholy, loneliness, love and death.

On 21 May 1838 an estimated 150,000 people assembled on Glasgow Green for a mass demonstration. There they witnessed the launch of the People’s Charter, a list of demands for political reform. The changes they called for included voting by secret ballot, equal-sized constituencies and, most importantly, that all men should have the vote. The Chartists, as they came to be known, were the first national mass working-class movement. In the decade that followed, they collected six million signatures for their Petitions to Parliament: all were rejected, but their campaign had a significant and lasting impact.

Melvyn Bragg and guests discuss the pioneering Danish astronomer Tycho Brahe (1546 – 1601) whose charts offered an unprecedented level of accuracy.In 1572 Brahe's observations of a new star challenged the idea, inherited from Aristotle, that the heavens were unchanging. He went on to create his own observatory complex on the Danish island of Hven, and there, working before the invention of the telescope, he developed innovative instruments and gathered a team of assistants, taking a highly systematic approach to observation. A second, smaller source of renown was his metal prosthetic nose, which he needed after a serious injury sustained in a duel. The image above shows Brahe aged 40, from the Atlas Major by Johann Blaeu.

Melvyn Bragg and guests discuss the discovery made in 1911 by the Dutch physicist Heike Kamerlingh Onnes (1853-1926). He came to call it Superconductivity and it is a set of physical properties that nobody predicted and that none, since, have fully explained. When he lowered the temperature of mercury close to absolute zero and ran an electrical current through it, Kamerlingh Onnes found not that it had low resistance but that it had no resistance. Later, in addition, it was noticed that a superconductor expels its magnetic field. In the century or more that has followed, superconductors have already been used to make MRI scanners and to speed particles through the Large Hadron Collider and they may perhaps bring nuclear fusion a little closer (a step that could be world changing).The image above is from a photograph taken by Stephen Blundell of a piece of superconductor levitating above a magnet.With Nigel Hussey Professor of Experimental Condensed Matter Physics at the University of Bristol and Radbout UniversitySuchitra Sebastian Professor of Physics at the Cavendish Laboratory at the University of CambridgeAndStephen Blundell Professor of Physics at the University of Oxford and Fellow of Mansfield CollegeProducer: Simon Tillotson

Melvyn Bragg and guests discuss A Theory of Justice by John Rawls (1921 - 2002) which has been called the most influential book in twentieth century political philosophy. It was first published in 1971. Rawls (pictured above) drew on his own experience in WW2 and saw the chance in its aftermath to build a new society, one founded on personal liberty and fair equality of opportunity. While in that just society there could be inequalities, Rawls’ radical idea was that those inequalities must be to the greatest advantage not to the richest but to the worst off.

Melvyn Bragg and guests discuss Donne (1573-1631), known now as one of England’s finest poets of love and notable in his own time as an astonishing preacher. He was born a Catholic in a Protestant country and, when he married Anne More without her father's knowledge, Donne lost his job in the government circle and fell into a poverty that only ended once he became a priest in the Church of England. As Dean of St Paul’s Cathedral, his sermons were celebrated, perhaps none more than his final one in 1631 when he was plainly in his dying days, as if preaching at his own funeral.The image above is from a miniature in the Royal Collection and was painted in 1616 by Isaac Oliver (1565-1617)With Mary Ann Lund Associate Professor in Renaissance English Literature at the University of LeicesterSue Wiseman Professor of Seventeenth Century Literature at Birkbeck, University of LondonAnd Hugh Adlington Professor of English Literature at the University of Birmingham

Melvyn Bragg and guests discuss the stench from the River Thames in the hot summer of 1858 and how it appalled and terrified Londoners living and working beside it, including those in the new Houses of Parliament which were still under construction. There had been an outbreak of cholera a few years before in which tens of thousands had died, and a popular theory held that foul smells were linked to diseases. The source of the problem was that London's sewage, once carted off to fertilise fields had recently, thanks to the modern flushing systems, started to flow into the river and, thanks to the ebb and flow of the tides, was staying there and warming in the summer sun. The engineer Joseph Bazalgette was given the task to build huge new sewers to intercept the waste, a vast network, so changing the look of London and helping ensure there were no further cholera outbreaks from contaminated water.The image above is from Punch, July 10th 1858 and it has this caption: The 'Silent Highway'-Man.

Melvyn Bragg and guests discuss Jane Austen’s last complete novel, which was published just before Christmas in 1817, five months after her death. It is the story of Anne Elliot, now 27 and (so we are told), losing her bloom, and of her feelings for Captain Wentworth who she was engaged to, 8 years before – an engagement she broke off under pressure from her father and godmother. When Wentworth, by chance, comes back into Anne Elliot's life, he is still angry with her and neither she nor Austen's readers can know whether it is now too late for their thwarted love to have a second chance.The image above is from a 1995 BBC adaptation of the novel, with Amanda Root and Ciarán Hinds WithKaren O’Brien Vice-Chancellor of Durham UniversityFiona Stafford Professor of English Language and Literature at the University of OxfordAndPaddy Bullard Associate Professor of English Literature and Book History at the University of ReadingProducer: Simon Tillotson

Melvyn Bragg and guests discuss Orson Welles' film, released in 1941, which is widely acclaimed as one of the greatest, if not the greatest, films yet made. Welles plays the lead role of Charles Foster Kane, a newspaper magnate, and Welles directed, produced and co-wrote this story of loneliness at the heart of a megalomaniac. The plot was partly inspired by the life of William Randolph Hearst, who then used the power of his own newspapers to try to suppress the film’s release. It was to take some years before Citizen Kane reached a fuller audience and, from that point, become so celebrated.The image above is of Kane addressing a public meeting while running for Governor.With Stella Bruzzi Professor of Film and Dean of Arts and Humanities at University College LondonIan Christie Professor of Film and Media History at Birkbeck, University of LondonAnd John David Rhodes Professor of Film Studies and Visual Culture at the University of CambridgeProducer: Simon Tillotson

Melvyn Bragg and guests discuss the momentum behind rebellion in Ireland in 1798, the people behind the rebellion and the impact over the next few years and after. Amid wider unrest, the United Irishmen set the rebellion on its way, inspired by the French and American revolutionaries and their pursuit of liberty. When it broke out in May the United Irishmen had an estimated two hundred thousand members, Catholic and Protestant, and the prospect of a French invasion fleet to back them. Crucially for the prospects of success, some of those members were British spies who exposed the plans and the military were largely ready - though not in Wexford where the scale of rebellion was much greater. The fighting was initially fierce and brutal and marked with sectarianism but had largely been suppressed by the time the French arrived in August to declare a short-lived republic. The consequences of the rebellion were to be far reaching, not least in the passing of Acts of Union in 1800.The image above is of Theobald Wolfe Tone (1763 - 1798), prominent member of the United IrishmenWith Ian McBride Foster Professor of Irish History at Hertford College, University of OxfordCatriona Kennedy Senior Lecturer in Modern History at the University of YorkAnd Liam Chambers Head of Department and Senior Lecturer in History at Mary Immaculate College, LimerickProducer: Simon Tillotson

Melvyn Bragg and guests discuss The Song of the Nibelungs, a twelfth century German epic, full of blood, violence, fantasy and bleakness. It is a foundational work of medieval literature, drawing on the myths of Scandinavia and central Europe. The poem tells of two couples, Siegfried and Kriemhild and Gunther and Brunhilda, whose lives are destroyed by lies and revenge. It was extremely popular in its time, sometimes rewritten with happier endings, and was rediscovered by German Romantics and has since been drawn from selectively by Wagner, Fritz Lang and, infamously, the Nazis looking to support ideas on German heritage.The image above is of Siegfried seeing Kriemhild for the first time, a miniature from the Hundeshagenschen Code manuscript dating from 15th Century.WithSarah Bowden Reader in German and Medieval Studies at King’s College LondonMark Chinca Professor of Medieval German and Comparative Literature at the University of CambridgeAndBettina Bildhauer Professor of Modern Languages at the University of St AndrewsProducer: Simon Tillotson

Melvyn Bragg and guests discuss the voyage of HMS Challenger which set out from Portsmouth in 1872 with a mission a to explore the ocean depths around the world and search for new life. The scale of the enterprise was breath taking and, for its ambition, it has since been compared to the Apollo missions. The team onboard found thousands of new species, proved there was life on the deepest seabeds and plumbed the Mariana Trench five miles below the surface. Thanks to telegraphy and mailboats, its vast discoveries were shared around the world even while Challenger was at sea, and they are still being studied today, offering insights into the ever-changing oceans that cover so much of the globe and into the health of our planet.The image above is from the journal of Pelham Aldrich R.N. who served on the Challenger Surveying Expedition from 1872-5.WithErika Jones Curator of Navigation and Oceanography at Royal Museums GreenwichSam Robinson Southampton Marine and Maritime Institute Research Fellow at the University of SouthamptonAndGiles Miller Principal Curator of Micropalaeontology at the Natural History Museum LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the speeches that became a byword for fierce attacks on political opponents. It was in the 4th century BC, in Athens, that Demosthenes delivered these speeches against the tyrant Philip II of Macedon, father of Alexander the Great, when Philip appeared a growing threat to Athens and its allies and Demosthenes feared his fellow citizens were set on appeasement. In what became known as The Philippics, Demosthenes tried to persuade Athenians to act against Macedon before it was too late; eventually he succeeded in stirring them, even if the Macedonians later prevailed. For these speeches prompting resistance, Demosthenes became famous as one of the Athenian democracy’s greatest freedom fighters. Later, in Rome, Cicero's attacks on Mark Antony were styled on Demosthenes and these too became known as Philippics.The image above is painted on the dome of the library of the National Assembly, Paris and is by Eugene Delacroix (1798-1863). It depicts Demosthenes haranguing the waves of the sea as a way of strengthening his voice for his speeches.With Paul Cartledge A. G.

Melvyn Bragg and guests discuss the Bauhaus which began in 1919 in Weimar, Germany, as a school for arts and crafts combined, and went on to be famous around the world. Under its first director, Walter Gropius, the Bauhaus moved to Dessau and extended its range to architecture and became associated with a series of white, angular, flat-roofed buildings reproduced from Shanghai to Chicago, aimed for modern living. The school closed after only 14 years while at a third location, Berlin, under pressure from the Nazis, yet its students and teachers continued to spread its ethos in exile, making it even more influential.The image above is of the Bauhaus Building, Dessau, designed by Gropius and built in 1925-6WithRobin Schuldenfrei Tangen Reader in 20th Century Modernism at The Courtauld Institute of ArtAlan Powers History Leader at the London School of ArchitectureAnd Michael White Professor of the History of Art at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss the rebellion that broke out in Jamaica on 11th October 1865 when Paul Bogle (1822-65) led a protest march from Stony Gut to the courthouse in nearby Morant Bay. There were many grounds for grievance that day and soon anger turned to bloodshed. Although the British had abolished slavery 30 years before, the plantation owners were still dominant and the conditions for the majority of people on Jamaica were poor. The British governor suppressed this rebellion brutally and soon people in Jamaica lost what right they had to rule themselves. Some in Britain, like Charles Dickens, supported the governor's actions while others, like Charles Darwin, wanted him tried for murder. The image above is from a Jamaican $2 banknote, printed after Paul Bogle became a National Hero in 1969.With Matthew J Smith Professor of History and Director of the Centre for the Study of the Legacies of British Slavery at University College LondonDiana Paton The William Robertson Professor of History at the University of EdinburghAndLawrence Goldman Emeritus Fellow in History at St Peter’s College, University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss the celebrated British poet of World War One. Wilfred Owen (1893-1918) had published only a handful of poems when he was killed a week before the end of the war, but in later decades he became seen as the essential British war poet. His works such as Anthem for Doomed Youth, Strange Meeting and Dulce et Decorum Est went on to be inseparable from the memory of the war and its futility. However, while Owen is best known for his poetry of the trenches, his letters offer a more nuanced insight into him such as his pride in being an officer in charge of others and in being a soldier who fought alongside his comrades.WithJane Potter Reader in The School of Arts at Oxford Brookes UniversityFran Brearton Professor of Modern Poetry at Queen’s University BelfastAndGuy Cuthbertson Professor of British Literature and Culture at Liverpool Hope UniversityProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of the greatest changes in the history of life on Earth. Around 400 million years ago some of our ancestors, the fish, started to become a little more like humans. At the swampy margins between land and water, some fish were turning their fins into limbs, their swim bladders into lungs and developed necks and eventually they became tetrapods, the group to which we and all animals with backbones and limbs belong. After millions of years of this transition, these tetrapod descendants of fish were now ready to leave the water for a new life of walking on land, and with that came an explosion in the diversity of life on Earth.The image above is a representation of Tiktaalik Roseae, a fish with some features of a tetrapod but not one yet, based on a fossil collected in the Canadian Arctic.WithEmily Rayfield Professor of Palaeobiology at the University of BristolMichael Coates Chair and Professor of Organismal Biology and Anatomy at the University of ChicagoAnd Steve Brusatte Professor of Palaeontology and Evolution at the University of EdinburghProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of the influential painters at the heart of the French Impressionist movement: Berthe Morisot (1841-1895). The men in her circle could freely paint in busy bars and public spaces, while Morisot captured the domestic world and found new, daring ways to paint quickly in the open air. Her work shows women as they were, to her: informal, unguarded, and not transformed or distorted for the eyes of men. The image above is one of her few self-portraits, though several portraits of her survive by other artists, chiefly her sister Edma and her brother-in-law Edouard Manet.

Melvyn Bragg and guests discuss the military order founded around 1119, twenty years after the Crusaders captured Jerusalem. For almost 200 years the Knights Templar were a notable fighting force and financial power in the Crusader States and Western Europe. Their mission was to protect pilgrims in the Holy Land, and they became extremely wealthy yet, as the crusader grip on Jerusalem slipped, their political fortune declined steeply. They were to be persecuted out of existence, with their last grand master burned at the stake in Paris in 1314, and that sudden end has contributed to the strength of the legends that have grown up around them.WithHelen Nicholson Professor of Medieval History at Cardiff UniversityMike Carr Lecturer in Late Medieval History at the University of EdinburghAnd Jonathan Phillips Professor of Crusading History at Royal Holloway, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss an atomic particle that's become inseparable from modernity. JJ Thomson discovered the electron 125 years ago, so revealing that atoms, supposedly the smallest things, were made of even smaller things. He pictured them inside an atomic ball like a plum pudding, with others later identifying their place outside the nucleus - and it is their location on the outer limit that has helped scientists learn so much about electrons and with electrons. We can use electrons to reveal the secrets of other particles and, while electricity exists whether we understand electrons or not, the applications of electricity and electrons grow as our knowledge grows. Many questions, though, remain unanswered.With Victoria Martin Professor of Collider Physics at the University of EdinburghHarry Cliff Research Fellow in Particle Physics at the University of CambridgeAndFrank Close Professor Emeritus of Theoretical Physics and Fellow Emeritus at Exeter College at the University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss Plato's account of the once great island of Atlantis out to the west, beyond the world known to his fellow Athenians, and why it disappeared many thousands of years before his time. There are no sources for this story other than Plato, and he tells it across two of his works, the Timaeus and the Critias, tantalizing his readers with evidence that it is true and clues that it is a fantasy. Atlantis, for Plato, is a way to explore what an ideal republic really is, and whether Athens could be (or ever was) one; to European travellers in the Renaissance, though, his story reflected their own encounters with distant lands, previously unknown to them, spurring generations of explorers to scour the oceans and in the hope of finding a lost world.The image above is from an engraving of the legendary island of Atlantis after a description by Athanasius Kircher (1602-1680).With Edith Hall Professor of Classics at Durham UniversityChristopher Gill Emeritus Professor of Ancient Thought at the University of ExeterAndAngie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldProducer: Simon Tillotson

Melvyn Bragg and guests discuss George Orwell's (1903-1950) final novel, published in 1949, set in a dystopian London which is now found in Airstrip One, part of the totalitarian superstate of Oceania which is always at war and where the protagonist, Winston Smith, works at the Ministry of Truth as a rewriter of history: 'Who controls the past,' ran the Party slogan, 'controls the future: who controls the present controls the past.' The influence of Orwell's novel is immeasurable, highlighting threats to personal freedom with concepts he named such as doublespeak, thoughtcrime, Room 101, Big Brother, memory hole and thought police.With David Dwan Professor of English Literature and Intellectual History at the University of OxfordLisa Mullen Teaching Associate in Modern Contemporary Literature at the University of CambridgeAndJohn Bowen Professor of English Literature at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss the origin of this personification of the English everyman and his development as both British and Britain in the following centuries. He first appeared along with Lewis Baboon (French) and Nicholas Frog (Dutch) in 1712 in a pamphlet that satirised the funding of the War of the Spanish Succession. The author was John Arbuthnot (1667-1735), a Scottish doctor and satirist who was part of the circle of Swift and Pope, and his John Bull was the English voter, overwhelmed by taxes that went not so much into the war itself but into the pockets of its financiers. For the next two centuries, Arbuthnot’s John Bull was a gift for cartoonists and satirists, especially when they wanted to ridicule British governments for taking advantage of the people’s patriotism. The image above is by William Charles, a Scottish engraver who emigrated to the United States, and dates from 1814 during the Anglo-American War of 1812.

Melvyn Bragg and guests discuss the largest and arguably the most astonishing religious structure on Earth, built for Suryavarman II in the 12th Century in modern-day Cambodia. It is said to have more stone in it than the Great Pyramid of Giza, and much of the surface is intricately carved and remarkably well preserved. For the last 900 years Angkor Wat has been a centre of religion, whether Hinduism, Buddhism or Animism or a combination of those, and a source of wonder to Cambodians and visitors from around the world.WithPiphal Heng Postdoctoral scholar at the Cotsen Institute and the Programme for Early Modern Southeast Asia at UCLAAshley Thompson Hiram W Woodward Chair of Southeast Asian Art at SOAS University of LondonAndSimon Warrack A stone conservator who has worked extensively at Angkor WatProducer: Simon Tillotson

Melvyn Bragg and guests discuss the celebrated Welsh poet, Dylan Thomas (1914 - 1953). He wrote some of his best poems before he was twenty in the first half of his short, remarkable life, and was prolific in the second half too with poems such as those set in London under the Blitz and reworkings of his childhood in Swansea, and his famous radio play Under Milk Wood (performed after his death). He was read widely and widely heard: with his reading tours in America and recordings of his works that sold in their hundreds of thousands after his death, he is credited with reviving the act of poetry as performance in the 20th century.WithNerys Williams Associate Professor of Poetry and Poetics at University College DublinJohn Goodby Professor of Arts and Culture at Sheffield Hallam UniversityAndLeo Mellor The Roma Gill Fellow in English at Murray Edwards College, University of CambridgeProducer: Simon Tillotson

Melvyn Bragg and guests discuss the abrupt transformation of stars after shining brightly for millions or billions of years, once they lack the fuel to counter the force of gravity. Those like our own star, the Sun, become red giants, expanding outwards and consuming nearby planets, only to collapse into dense white dwarves. The massive stars, up to fifty times the mass of the Sun, burst into supernovas, visible from Earth in daytime, and become incredibly dense neutron stars or black holes. In these moments of collapse, the intense heat and pressure can create all the known elements to form gases and dust which may eventually combine to form new stars, new planets and, as on Earth, new life.The image above is of the supernova remnant Cassiopeia A, approximately 10,000 light years away, from a once massive star that died in a supernova explosion that was first seen from Earth in 1690WithMartin Rees Astronomer Royal, Fellow of Trinity College, CambridgeCarolin Crawford Emeritus Member of the Institute of Astronomy and Emeritus Fellow of Emmanuel College, University of CambridgeAndMark Sullivan Professor of Astrophysics at the University of SouthamptonProducer: Simon Tillotson

Melvyn Bragg and guests discuss ideas of Georg Wilhelm Friedrich Hegel (1770 - 1831) on history. Hegel, one of the most influential of the modern philosophers, described history as the progress in the consciousness of freedom, asking whether we enjoy more freedom now than those who came before us. To explore this, he looked into the past to identify periods when freedom was moving from the one to the few to the all, arguing that once we understand the true nature of freedom we reach an endpoint in understanding. That end of history, as it's known, describes an understanding of freedom so far progressed, so profound, that it cannot be extended or deepened even if it can be lost.WithSally Sedgwick Professor and Chair of Philosophy at Boston UniversityRobert Stern Professor of Philosophy at the University of SheffieldAnd Stephen Houlgate Professor of Philosophy at the University of WarwickProducer: Simon Tillotson

Melvyn Bragg and guests discuss the Czech educator Jan Amos Komenský (1592-1670) known throughout Europe in his lifetime under the Latin version of his name, Comenius. A Protestant and member of the Unity of Brethren, he lived much of his life in exile, expelled from his homeland under the Catholic Counter-Reformation, and he wanted to address the deep antagonisms underlying the wars that were devastating Europe especially The Thirty Years War (1618-1648). A major part of his plan was Universal Education, in which everyone could learn about everything, and better understand each other and so tolerate their religious differences and live side by side. His ideas were to have a lasting influence on education, even though the peace that followed the Thirty Years War only entrenched the changes in his homeland that made his life there impossible.The image above is from a portrait of Comenius by Jürgen Ovens, 1650 - 1670, painted while he was living in Amsterdam and held in the RikjsmuseumWithVladimir Urbanek Senior Researcher in the Department of Comenius Studies and Early Modern Intellectual History at the Institute of Philosophy of the Czech Academy of SciencesSuzanna Ivanic Lecturer in Early Modern European History at the University of KentAndHoward Hotson Professor of Early Modern Intellectual History at the University of Oxford and Fellow of St Anne’s CollegeProducer: Simon Tillotson

Melvyn Bragg and guests discuss two of China’s greatest poets, Li Bai and Du Fu, who wrote in the 8th century in the Tang Era. Li Bai (701-762AD) is known for personal poems, many of them about drinking wine, and for finding the enjoyment in life. Du Fu (712-770AD), a few years younger, is more of an everyman, writing in the upheaval of the An Lushan Rebellion (755-763AD). Together they have been a central part of Chinese culture for over a millennium, reflecting the balance between the individual and the public life, and one sign of their enduring appeal is that there is rarely agreement on which of them is the greater.The image above is intended to depict Du Fu.With Tim Barrett Professor Emeritus of East Asian History at SOAS, University of LondonTian Yuan Tan Shaw Professor of Chinese at the University of Oxford and Professorial Fellow at University CollegeAndFrances Wood Former Curator of the Chinese Collections at the British LibraryProducer: Simon Tillotson

Melvyn Bragg and guests discuss the impact of David I of Scotland (c1084-1153) on his kingdom and on neighbouring lands. The youngest son of Malcolm III, he was raised in exile in the Anglo-Norman court and became Earl of Huntingdon and Prince of Cumbria before claiming the throne in 1124. He introduced elements of what he had learned in England and, in the next decades, his kingdom saw new burghs, new monasteries, new ways of governing and the arrival of some very influential families, earning him the reputation of The Perfect King.With Richard Oram Professor of Medieval and Environmental History at the University of StirlingAlice Taylor Professor of Medieval History at King’s College LondonAndAlex Woolf Senior Lecturer in History at the University of St AndrewsProducer: Simon Tillotson

Melvyn Bragg and guests discuss the accounts by Eusebius of Caesarea (c260-339 AD) and others of the killings of Christians in the first three centuries after the crucifixion of Jesus. Eusebius was writing in a time of peace, after The Great Persecution that had started with Emperor Diocletian in 303 AD and lasted around eight years. Many died under Diocletian, and their names are not preserved, but those whose deaths are told by Eusebius became especially celebrated and their stories became influential. Through his writings, Eusebius shaped perceptions of what it meant to be a martyr in those years, and what it meant to be a Christian.The image above is of The Martyrdom of Saint Blandina (1886) at the Church of Saint-Blandine de Lyon, FranceWith:Candida Moss Edward Cadbury Professor of Theology at the University of BirminghamKate Cooper Professor of History at Royal Holloway, University of LondonAndJames Corke-Webster Senior Lecturer in Classics, History and Liberal Arts at King’s College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the French playwright who, in 1791, wrote The Declaration of the Rights of Woman and of the Female Citizen. This was Olympe de Gouges (1748-93) and she was responding to The Declaration of the Rights of Man and of the Citizen from 1789, the start of the French Revolution which, by excluding women from these rights, had fallen far short of its apparent goals. Where the latter declared ‘men are born equal’, she asserted ‘women are born equal to men,’ adding, ‘since women are allowed to mount the scaffold, they should also be allowed to stand in parliament and defend their rights’. Two years later this playwright, novelist, activist and woman of letters did herself mount the scaffold, two weeks after Marie Antoinette, for the crime of being open to the idea of a constitutional monarchy and, for two hundred years, her reputation died with her, only to be revived with great vigour in the last 40 years.With Catriona Seth Marshal Foch Professor of French Literature at the University of OxfordKatherine Astbury Professor of French Studies at the University of WarwickAndSanja Perovic Reader in 18th century French studies at King’s College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of our ancestors, Homo erectus, who thrived on Earth for around two million years whereas we, Homo sapiens, emerged only in the last three hundred thousand years. Homo erectus, or Upright Man, spread from Africa to Asia and it was on the Island of Java that fossilised remains were found in 1891 in an expedition led by Dutch scientist Eugène Dubois. Homo erectus people adapted to different habitats, ate varied food, lived in groups, had stamina to outrun their prey; and discoveries have prompted many theories on the relationship between their diet and the size of their brains, on their ability as seafarers, on their creativity and on their ability to speak and otherwise communicate.The image above is from a diorama at the Moesgaard Museum in Denmark, depicting the Turkana Boy referred to in the programme.

Melvyn Bragg and guests discuss the influential novella of John Polidori (1795-1821) published in 1819 and attributed first to Lord Byron (1788-1824) who had started a version of it in 1816 at the Villa Diodati in the Year Without A Summer. There Byron, his personal physician Polidori, Mary and Percy Shelley and Claire Clairmont had whiled away the weeks of miserable weather by telling ghost stories, famously giving rise to Mary Shelley's 'Frankenstein'. Emerging soon after, 'The Vampyre' thrilled readers with its aristocratic Lord Ruthven who glutted his thirst with the blood of his victims, his status an abrupt change from the stories of peasant vampires of eastern and central Europe that had spread in the 18th Century with the expansion of the Austro-Hungarian empire. The connection with Lord Byron gave the novella a boost, and soon 'The Vampyre' spawned West End plays, penny dreadfuls such as 'Varney the Vampire', Bram Stoker’s 'Dracula', F.W Murnau's film 'Nosferatu A Symphony of Horror', and countless others.The image above is of Bela Lugosi (1882-1956) as Count Mora in Metro-Goldwyn-Meyer's 'Vampires of Prague' (1935)With Nick Groom Professor of Literature in English at the University of MacauSamantha George Associate Professor of Research in Literature at the University of HertfordshireAnd Martyn Rady Professor Emeritus of Central European History at University College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the astonishing work of Michelangelo (1477-1564) in this great chapel in the Vatican, firstly the ceiling with images from Genesis (of which the image above is a detail) and later The Last Judgement on the altar wall. For the Papacy, Michelangelo's achievement was a bold affirmation of the spiritual and political status of the Vatican, of Rome and of the Catholic Church. For the artist himself, already famous as the sculptor of David in Florence, it was a test of his skill and stamina, and of the potential for art to amaze which he realised in his astonishing mastery of the human form.WithCatherine Fletcher Professor of History at Manchester Metropolitan UniversitySarah Vowles The Smirnov Family Curator of Italian and French Prints and Drawings at the British MuseumAndMatthias Wivel The Aud Jebsen Curator of Sixteenth-Century Italian Paintings at the National GalleryProducer: Simon Tillotson

Melvyn Bragg and guests discuss what is reputedly the most performed of all Greek tragedies. Antigone, by Sophocles (c496-c406 BC), is powerfully ambiguous, inviting the audience to reassess its values constantly before the climax of the play resolves the plot if not the issues. Antigone is barely a teenager and is prepared to defy her uncle Creon, the new king of Thebes, who has decreed that nobody should bury the body of her brother, a traitor, on pain of death. This sets up a conflict between generations, between the state and the individual, uncle and niece, autocracy and pluralism, and it releases an enormous tragic energy that brings sudden death to Antigone, her fiance Haemon who is also Creon's son, and to Creon's wife Eurydice, while Creon himself is condemned to a living death of grief.WithEdith Hall Professor of Classics at Durham UniversityOliver Taplin Emeritus Professor of Classics, University of OxfordAndLyndsay Coo Senior Lecturer in Ancient Greek Language and Literature at the University of BristolProducer: Simon Tillotson

Melvyn Bragg and guests discuss the idea of charismatic authority developed by Max Weber (1864-1920) to explain why people welcome some as their legitimate rulers and follow them loyally, for better or worse, while following others only dutifully or grudgingly. Weber was fascinated by those such as Napoleon (above) and Washington who achieved power not by right, as with traditional monarchs, or by law as with the bureaucratic world around him in Germany, but by revolution or insurrection. Drawing on the experience of religious figures, he contended that these leaders, often outsiders, needed to be seen as exceptional, heroic and even miraculous to command loyalty, and could stay in power for as long as the people were enthralled and the miracles they had promised kept coming. After the Second World War, Weber's idea attracted new attention as a way of understanding why some reviled leaders once had mass support and, with the arrival of television, why some politicians were more engaging and influential on screen than others.

Melvyn Bragg and guests discuss the study of earthquakes. A massive earthquake in 1755 devastated Lisbon, and this disaster helped inspire a new science of seismology which intensified after San Francisco in 1906 and advanced even further with the need to monitor nuclear tests around the world from 1945 onwards. While we now know so much more about what lies beneath the surface of the Earth, and how rocks move and crack, it remains impossible to predict when earthquakes will happen. Thanks to seismology, though, we have a clearer idea of where earthquakes will happen and how to make some of them less hazardous to lives and homes.WithRebecca Bell Senior lecturer in Geology and Geophysics at Imperial College LondonZoe Mildon Lecturer in Earth Sciences and Future Leaders Fellow at the University of PlymouthAnd James Hammond Reader in Geophysics at Birkbeck, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the ancient Sanskrit text the Arthashastra, regarded as one of the major works of Indian literature. Written in the style of a scientific treatise, it provides rulers with a guide on how to govern their territory and sets out what the structure, economic policy and foreign affairs of the ideal state should be. According to legend, it was written by Chanakya, a political advisor to the ruler Chandragupta Maurya (reigned 321 – 297 BC) who founded the Mauryan Empire, the first great Empire in the Indian subcontinent. As the Arthashastra asserts that a ruler should pursue his goals ruthlessly by whatever means is required, it has been compared with the 16th-century work The Prince by Machiavelli. Today, it is widely viewed as presenting a sophisticated and refined analysis of the nature, dynamics and challenges of rulership, and scholars value it partly because it undermines colonial stereotypes of what early South Asian society was like.

Melvyn Bragg and guests discuss the Russian prince who became a leading anarchist and famous scientist. Kropotkin (1842 - 1921) was born into privilege, very much in the highest circle of Russian society as a pageboy for the Tsar, before he became a republican in childhood and dropped the title 'Prince'. While working in Siberia, he started reading about anarchism and that radicalised him further, as did his observations of Siberian villagers supporting each other without (or despite) a role for the State. He made a name for himself as a geographer but soon his politics landed him in jail in St Petersburg, from which he escaped to exile in England where he was fêted, with growing fame leading to lecture tours in the USA. His time in Siberia also inspired his ideas on the importance of mutual aid in evolution, a counter to the dominant idea from Darwin and Huxley that life was a gladiatorial combat in which only the fittest survived. Kropotkin became such a towering figure in public life that, returning to Russia, he was able to challenge Lenin without reprisal, and Lenin in turn permitted his enormous public funeral there, attended by 20,000 mourners.With Ruth Kinna Professor of Political Theory at Loughborough UniversityLee Dugatkin Professor of Biology at the University of LouisvilleAndSimon Dixon The Sir Bernard Pares Professor of Russian History at University College London

Melvyn Bragg and guests discuss William Shakespeare's famous tragedy, written in the early 1590s after a series of histories and comedies. His audience already knew the story of the feuding Capulets and Montagues in Verona and the fate of the young lovers from their rival houses, but not how Shakespeare would tell it and, with his poetry and plotting, he created a work so powerful and timeless that his play has shaped the way we talk of love, especially young love, ever since.The image above is of Mrs Patrick Campbell ('Mrs Pat') as Juliet and Johnson Forbes-Robinson as Romeo in a scene from the 1895 production at the Lyceum Theatre, LondonWithHelen Hackett Professor of English Literature at University College LondonPaul Prescott Professor of English and Theatre at the University of California MercedAndEmma Smith Professor of Shakespeare Studies at Hertford College, University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of the most celebrated thinkers of the twentieth century. Walter Benjamin (1892-1940) was a German Jewish philosopher, critic, historian, an investigator of culture, a maker of radio programmes and more. Notably, in his Arcades Project, he looked into the past of Paris to understand the modern age and, in The Work of Art in the Age of Mechanical Reproduction, examined how the new media of film and photography enabled art to be politicised, and politics to become a form of art. The rise of the Nazis in Germany forced him into exile, and he worked in Paris in dread of what was to come; when his escape from France in 1940 was blocked at the Spanish border, he took his own life.

Melvyn Bragg and guests discuss the momentum behind teetotalism in 19th Century Britain, when calls for moderation gave way to complete abstinence in pursuit of a better life. Although arguments for temperance had been made throughout the British Isles beforehand, the story of the organised movement in Britain is often said to have started in 1832 in Preston, when Joseph Livesey and seven others gave a pledge to abstain. The movement grew quickly, with Temperance Halls appearing as new social centres in towns in place of pubs, and political parties being drawn into taking sides either to support abstinence or impose it or reject it. The image above, which appeared in The Teetotal Progressionist in 1852, is an example of the way in which images contained many points of temperance teaching, and is © Copyright Livesey Collection at the University of Central Lancashire.

Melvyn Bragg and guests discuss one of the outstanding French writers of the twentieth century. The novels of Sidonie-Gabrielle Colette (1873 - 1954) always had women at their centre, from youth to mid-life to old age, and they were phenomenally popular, at first for their freshness and frankness about women’s lives, as in the Claudine stories, and soon for their sheer quality as she developed as a writer. Throughout her career she intrigued readers by inserting herself, or a character with her name, into her works, fictionalising her life as a way to share her insight into the human experience.With Diana Holmes Professor of French at the University of LeedsMichèle Roberts Writer, novelist, poet and Emeritus Professor of Creative Writing at the University of East AngliaAndBelinda Jack Fellow and Tutor in French Literature and Language at Christ Church, University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss the system that flourished from 1870 when gold became dominant and more widely available, following gold rushes in California and Australia. Banknotes could be exchanged for gold at central banks, the coins in circulation could be gold (as with the sovereign in the image above, initially worth £1), gold could be freely imported and exported, and many national currencies around the world were tied to gold and so to each other. The idea began in Britain, where sterling was seen as good as gold, and when other countries rushed to the Gold Standard the confidence in their currencies grew, and world trade took off and, for a century, gold was seen as a vital component of the world economy, supporting stability and confidence. The system came with constraints on government ability to respond to economic crises, though, and has been blamed for deepening and prolonging the Great Depression of the 1930s.

Melvyn Bragg and guests discuss Thomas Hardy (1840 -1928) and his commitment to poetry, which he prized far above his novels. In the 1890s, once he had earned enough from his fiction, Hardy stopped writing novels altogether and returned to the poetry he had largely put aside since his twenties. He hoped that he might be ranked one day alongside Shelley and Byron, worthy of inclusion in a collection such as Palgrave's Golden Treasury which had inspired him. Hardy kept writing poems for the rest of his life, in different styles and metres, and he explored genres from nature, to war, to epic. Among his best known are what he called his Poems of 1912 to 13, responding to his grief at the death of his first wife, Emma (1840 -1912), who he credited as the one who had made it possible for him to leave his work as an architect's clerk and to write the novels that made him famous.WithMark Ford Poet, and Professor of English and American Literature, University College London.Jane Thomas Emeritus Professor of English at the University of Hull and Senior Visiting Research Fellow at the University of LeedsAnd Tim Armstrong Professor of Modern English and American Literature at Royal Holloway, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the Austrian-born film director Fritz Lang (1890-1976), who was one of the most celebrated film-makers of the 20th century. He worked first in Weimar Germany, creating a range of films including the startling and subversive Mabuse the Gambler and the iconic but ruinously expensive Metropolis before arguably his masterpiece, M, with both the police and the underworld hunting for a child killer in Berlin, his first film with sound. The rise of the Nazis prompted Lang's move to Hollywood where he developed some of his Weimar themes in memorable and disturbing films such as Fury and The Big Heat.

Melvyn Bragg and guests discuss the empire that flourished in the Late Bronze Age in what is now Turkey, and which, like others at that time, mysteriously collapsed. For the next three thousand years these people of the Land of Hatti, as they called themselves, were known only by small references to their Iron Age descendants in the Old Testament and by unexplained remains in their former territory. Discoveries in their capital of Hattusa just over a century ago brought them back to prominence, including cuneiform tablets such as one (pictured above) which relates to an agreement with their rivals, the Egyptians. This agreement has since become popularly known as the Treaty of Kadesh and described as the oldest recorded peace treaty that survives to this day, said to have followed a great chariot battle with Egypt in 1274 BC near the Orontes River in northern Syria.

Melvyn Bragg and guests discuss Charles Dickens' novella, written in 1843 when he was 31, which has become intertwined with his reputation and with Christmas itself. Ebenezer Scrooge is the miserly everyman figure whose joyless obsession with money severs him from society and his own emotions, and he is only saved after recalling his lonely past, seeing what he is missing now and being warned of his future, all under the guidance of the ghosts of Christmases Past, Present and Yet To Come. Redeemed, Scrooge comes to care in particular about one of the many minor characters in the story who make a great impact, namely Tiny Tim, the disabled child of the poor and warm-hearted Cratchit family, with his cry, "God bless us, every one!"WithJuliet John Professor of English Literature and Dean of Arts and Social Sciences at City, University of LondonJon Mee Professor of Eighteenth-Century Studies at the University of YorkAndDinah Birch Pro-Vice-Chancellor for Cultural Engagement and Professor of English Literature at the University of LiverpoolProducer: Simon Tillotson

Melvyn Bragg and guests discuss the violent protests in China on 4th May 1919 over the nation's humiliation in the Versailles Treaty after World War One. China had supported the Allies, sending workers to dig trenches, and expected to regain the German colonies on its territory, but the Allies and China's leaders chose to give that land to Japan instead. To protestors, this was a travesty and reflected much that was wrong with China, with its corrupt leaders, division by warlords, weakness before Imperial Europe and outdated ideas and values. The movement around 4th May has since been seen as a watershed in China’s development in the 20th century, not least as some of those connected with the movement went on to found the Communist Party of China a few years later.The image above is of students from Peking University marching with banners during the May Fourth demonstrations in 1919.With Rana Mitter Professor of the History and Politics of Modern China and Fellow of St Cross College, University of OxfordElisabeth Forster Lecturer in Chinese History at the University of SouthamptonAnd Song-Chuan Chen Associate Professor in History at the University of WarwickProducer: Simon Tillotson

Melvyn Bragg and guests discuss the events of 21st October 1805, in which the British fleet led by Nelson destroyed a combined Franco-Spanish fleet in the Atlantic off the coast of Spain. Nelson's death that day was deeply mourned in Britain, and his example proved influential, and the battle was to help sever ties between Spain and its American empire. In France meanwhile, even before Nelson's body was interred at St Paul's, the setback at Trafalgar was overshadowed by Napoleon's decisive victory over Russia and Austria at Austerlitz, though Napoleon's search for his lost naval strength was to shape his plans for further conquests.The image above is from 'The Battle of Trafalgar' by JMW Turner (1824).WithJames Davey Lecturer in Naval and Maritime History at the University of ExeterMarianne Czisnik Independent researcher on Nelson and editor of his letters to Lady HamiltonAndKenneth Johnson Research Professor of National Security at Air University, AlabamaProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of Plato's most striking dialogues, in which he addresses the real nature of power and freedom, and the relationship between pleasure and true self-interest. As he tests these ideas, Plato creates powerful speeches, notably from Callicles who claims that laws of nature trump man-made laws, that might is right, and that rules are made by weak people to constrain the strong in defiance of what is natural and proper. Gorgias is arguably the most personal of all of Plato's dialogues, with its hints of a simmering fury at the system in Athens that put his mentor Socrates to death, and where rhetoric held too much sway over people.

Melvyn Bragg and guests discuss the British phase of a movement that spread across Europe in the mid-19th and early 20th centuries. Influenced by Charles Baudelaire and by Walter Pater, these Decadents rejected the mainstream Victorian view that art needed a moral purpose, and valued instead the intense sensations art provoked, celebrating art for art’s sake. Oscar Wilde was at its heart, Aubrey Beardsley adorned it with his illustrations and they, with others, provoked moral panic with their supposed degeneracy. After burning brightly, the movement soon lost its energy in Britain yet it has proved influential.The illustration above, by Beardsley, is from the cover of the first edition of The Yellow Book in April 1894.WithNeil Sammells Professor of English and Irish Literature and Deputy Vice Chancellor at Bath Spa UniversityKate Hext Senior Lecturer in English Literature at the University of ExeterAndAlex Murray Senior Lecturer in English at Queen’s University, BelfastProducer: Simon Tillotson

Melvyn Bragg and guests discuss William Herschel (1738 – 1822) and his sister Caroline Herschel (1750 – 1848) who were born in Hanover and made their reputation in Britain. William was one of the most eminent astronomers in British history. Although he started life as a musician, as a young man he became interested in studying the night sky. With an extraordinary talent, he constructed telescopes that were able to see further and more clearly than any others at the time. He is most celebrated today for discovering the planet Uranus and detecting what came to be known as infrared radiation. Caroline also became a distinguished astronomer, discovering several comets and collaborating with her brother.WithMonica Grady Professor of Planetary and Space Sciences at the Open UniversityCarolin Crawford Institute of Astronomy, Cambridge and an Emeritus Fellow of Emmanuel College, University of CambridgeAndJim Bennett Keeper Emeritus at the Science Museum in London.Studio producer: John Goudie

Melvyn Bragg and guests discuss an early masterpiece of French epic poetry, from the 12th Century. It is a reimagining of Charlemagne’s wars in Spain in the 8th Century in which Roland, his most valiant knight, chooses death before dishonour, guarding the army’s rear from a pagan ambush as it heads back through the Roncesvalles Pass in the Pyrenees. If he wanted to, Roland could blow on his oliphant, his elephant tusk horn, to summon help by calling back Charlemagne's army, but according to his values that would bring shame both on him and on France, and he would rather keep killing pagans until he is the last man standing and the last to die.The image above is taken from an illustration of Charlemagne finding Roland after the Battle of Roncevaux/Roncesvalles, from 'Les Grandes Chroniques de France', c.1460 by Jean Fouquet, Bibliotheque Nationale, Paris, Ms Fr 6465 f.113 With Laura Ashe Professor of English Literature and Fellow in English at Worcester College, University of OxfordMiranda Griffin Assistant Professor of Medieval French at the University of Cambridge and Fellow of Murray Edwards CollegeAndLuke Sunderland Professor in the School of Modern Languages and Cultures at Durham UniversityStudio producer: John Goudie

Melvyn Bragg and guests discuss the simple animals which informed Charles Darwin's first book, The Structure and Distribution of Coral Reefs, published in 1842. From corals, Darwin concluded that the Earth changed very slowly and was not fashioned by God. Now coral reefs, which some liken to undersea rainforests, are threatened by human activity, including fishing, pollution and climate change.

Melvyn Bragg and guests discuss the author and philosopher Iris Murdoch (1919 - 1999). In her lifetime she was most celebrated for her novels such as The Bell and The Black Prince, but these are now sharing the spotlight with her philosophy. Responding to the horrors of the Second World War, she argued that morality was not subjective or a matter of taste, as many of her contemporaries held, but was objective, and good was a fact we could recognize. To tell good from bad, though, we would need to see the world as it really is, not as we want to see it, and her novels are full of characters who are not yet enlightened enough to do that.WithAnil Gomes Fellow and Tutor in Philosophy at Trinity College, University of OxfordAnne Rowe Visiting Professor at the University of Chichester and Emeritus Research Fellow with the Iris Murdoch Archive Project at Kingston UniversityAndMiles Leeson Director of the Iris Murdoch Research Centre and Reader in English Literature at the University of ChichesterProducer: Simon Tillotson

Melvyn Bragg and guests discuss the republic that emerged from the union of the Kingdom of Poland and Grand Duchy of Lithuania in the 14th Century. At first this was a personal union, similar to that of James I and VI in Britain, but this was formalised in 1569 into a vast republic, stretching from the Baltic to the Black Sea. Kings and princes from across Europe would compete for parliament to elect them King and Grand Duke, and the greatest power lay with the parliaments. When the system worked well, the Commonwealth was a powerhouse, and it was their leader Jan Sobieski who relieved the siege of Vienna in 1683, defeating the Ottomans. Its neighbours exploited its parliament's need for unanimity, though, and this contributed to its downfall. Austria, Russia and Prussia divided its territory between them from 1772, before the new, smaller states only emerged in the 20th Century.

Melvyn Bragg and guests discuss the race to build an atom bomb in the USA during World War Two. Before the war, scientists in Germany had discovered the potential of nuclear fission and scientists in Britain soon argued that this could be used to make an atom bomb, against which there could be no defence other than to own one. The fear among the Allies was that, with its head start, Germany might develop the bomb first and, unmatched, use it on its enemies. The USA took up the challenge in a huge engineering project led by General Groves and Robert Oppenheimer and, once the first bomb had been exploded at Los Alamos in July 1945, it appeared inevitable that the next ones would be used against Japan with devastating results.The image above is of Robert Oppenheimer and General Groves examining the remains of one the bases of the steel test tower, at the atomic bomb Trinity Test site, in September 1945.WithBruce Cameron Reed The Charles A.

Melvyn Bragg and guests discuss Anne Bronte's second novel, published in 1848, which is now celebrated alongside those of her sisters but which Charlotte Bronte tried to suppress as a 'mistake'. It examines the life of Helen, who has escaped her abusive husband Arthur Huntingdon with their son to live at Wildfell Hall as a widow under the alias 'Mrs Graham', and it exposes the men in her husband's circle who gave her no choice but to flee. Early critics attacked the novel as coarse, as misrepresenting male behaviour, and as something no woman or girl should ever read; soon after Anne's death, Charlotte suggested the publisher should lose it for good. In recent decades, though, its reputation has climbed and it now sits with Jane Eyre and Wuthering Heights as one of the great novels by the Bronte sisters.The image above shows Tara Fitzgerald as Helen Graham in a 1996 BBC adaptation.WithAlexandra Lewis Lecturer in English and Creative Writing at the University of Newcastle (Australia)Marianne Thormählen Professor Emerita in English Studies, Lund UniversityAndJohn Bowen Professor of Nineteenth Century Literature at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss the Greek writer known as the father of histories, dubbed by his detractors as the father of lies. Herodotus (c484 to 425 BC or later) was raised in Halicarnassus in modern Turkey when it was part of the Persian empire and, in the years after the Persian Wars, set about an inquiry into the deep background to those wars. He also aimed to preserve what he called the great and marvellous deeds of Greeks and non-Greeks, seeking out the best evidence for past events and presenting the range of evidence for readers to assess. Plutarch was to criticise Herodotus for using this to promote the least flattering accounts of his fellow Greeks, hence the 'father of lies', but the depth and breadth of his Histories have secured his reputation from his lifetime down to the present day.WithTom Harrison Professor of Ancient History at the University of St AndrewsEsther Eidinow Professor of Ancient History at the University of BristolAndPaul Cartledge A.

Melvyn Bragg and guests discuss the remarkable diversity of the animals that dominated life on land in the Triassic, before the rise of the dinosaurs in the Jurassic, and whose descendants are often described wrongly as 'living fossils'. For tens of millions of years, the ancestors of alligators and Nile crocodiles included some as large as a bus, some running on two legs like a T Rex and some that lived like whales. They survived and rebounded from a series of extinction events but, while the range of habitats of the dinosaur descendants such as birds covers much of the globe, those of the crocodiles have contracted, even if the animals themselves continue to evolve today as quickly as they ever have.WithAnjali Goswami Research Leader in Life Sciences and Dean of Postgraduate Education at the Natural History MuseumPhilip Mannion Lecturer in the Department of Earth Sciences at University College London AndSteve Brusatte Professor of Palaeontology and Evolution at the University of EdinburghProducer Simon Tillotson

Melvyn Bragg and guests discuss the collection of poems published in 1609 by Thomas Thorpe: Shakespeare’s Sonnets, “never before imprinted”. Yet, while some of Shakespeare's other poems and many of his plays were often reprinted in his lifetime, the Sonnets were not a publishing success. They had to make their own way, outside the main canon of Shakespeare’s work: wonderful, troubling, patchy, inspiring and baffling, and they have appealed in different ways to different times. Most are addressed to a man, something often overlooked and occasionally concealed; one early and notorious edition even changed some of the pronouns.

Melvyn Bragg and guests discuss the life and ideas of one of the great historians, best known for his History of the Decline and Fall of the Roman Empire (published 1776-89). According to Gibbon (1737-94) , the idea for this work came to him on 15th of October 1764 as he sat musing amidst the ruins of Rome, while barefooted friars were singing vespers in the Temple of Jupiter. Decline and Fall covers thirteen centuries and is an enormous intellectual undertaking and, on publication, it became a phenomenal success across Europe.

Melvyn Bragg and guests discuss Charles Booth's survey, The Life and Labour of the People in London, published in 17 volumes from 1889 to 1903. Booth (1840-1916), a Liverpudlian shipping line owner, surveyed every household in London to see if it was true, as claimed, that as many as a quarter lived in poverty. He found that it was closer to a third, and that many of these were either children with no means of support or older people no longer well enough to work. He went on to campaign for an old age pension, and broadened the impact of his findings by publishing enhanced Ordnance Survey maps with the streets coloured according to the wealth of those who lived there.The image above is of an organ grinder on a London street, circa 1893, with children dancing to the Pas de QuatreWithEmma Griffin Professor of Modern British History at the University of East AngliaSarah Wise Adjunct Professor at the University of CaliforniaAndLawrence Goldman Emeritus Fellow in History at St Peter’s College, University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss the insight into our relationship with the world that Immanuel Kant (1724-1804) shared in his book The Critique of Pure Reason in 1781. It was as revolutionary, in his view, as when the Polish astronomer Copernicus realised that Earth revolves around the Sun rather than the Sun around Earth. Kant's was an insight into how we understand the world around us, arguing that we can never know the world as it is, but only through the structures of our minds which shape that understanding. This idea, that the world depends on us even though we do not create it, has been one of Kant’s greatest contributions to philosophy and influences debates to this day.

Melvyn Bragg and guests discuss the period between the execution of Charles I in 1649 and the unexpected restoration of his son Charles II in 1660, known as The Interregnum. It was marked in England by an elusive pursuit of stability, with serious consequences in Scotland and notorious ones in Ireland. When Parliament executed Charles it had also killed Scotland and Ireland’s king, without their consent; Scotland immediately declared Charles II king of Britain, and Ireland too favoured Charles. In the interests of political and financial security, Parliament's forces, led by Oliver Cromwell, soon invaded Ireland and then turned to defeating Scotland. However, the improvised power structures in England did not last and Oliver Cromwell's death in 1658 was followed by the threat of anarchy. In England, Charles II had some success in overturning the changes of the 1650s but there were lasting consequences for Scotland and the notorious changes in Ireland were entrenched.The Dutch image of Oliver Cromwell, above, was published by Joost Hartgers c1649With Clare Jackson Senior Tutor at Trinity Hall, University of CambridgeMicheál Ó Siochrú Professor in Modern History at Trinity College DublinAndLaura Stewart Professor in Early Modern History at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of the great novels of China’s Ming era, and perhaps the most loved. Written in 1592, it draws on the celebrated travels of a real monk from China to India a thousand years before, and on a thousand years of retellings of that story, especially the addition of a monkey as companion who, in the novel, becomes supersimian. For most readers the monk, Tripitaka, is upstaged by this irrepressible Monkey with his extraordinary powers, accompanied by the fallen but recovering deities, Pigsy and Sandy.The image above, from the caricature series Yoshitoshi ryakuga or Sketches by Yoshitoshi, is of Monkey creating an army by plucking out his fur and blowing it into the air, and each hair becomes a monkey-warrior.With Julia Lovell Professor of Modern Chinese History and Literature at Birkbeck, University of LondonChiung-yun Evelyn Liu Associate Research Fellow at the Institute of Chinese Literature and Philosophy, Academia Sinica, TaiwanAndCraig Clunas Professor Emeritus of the History of Art at Trinity College, University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss the search for Longitude while at sea. Following efforts by other maritime nations, the British Government passed the Longitude Act in 1714 to reward anyone who devised reliable means for ships to determine their longitude at sea. Mariners could already calculate how far they were north or south, the Latitude, using the Pole Star, but voyaging across the Atlantic to the Caribbean was much less predictable as navigators could not be sure how far east or west they were, a particular problem when heading for islands. It took fifty years of individual genius and collaboration in Britain and across Europe, among astronomers, clock makers, mathematicians and sailors, for the problem to be resolved.WithRebekah Higgitt Principal Curator of Science at National Museums ScotlandJim Bennett Keeper Emeritus at the Science MuseumAnd Simon Schaffer Professor of History and Philosophy of Science at the University of CambridgeProducer: Simon Tillotson

Melvyn Bragg and guests discuss the years of bloody conflict that saw Simon de Montfort (1205-65) become the most powerful man in England, with Henry III as his prisoner. With others, he had toppled Henry in 1258 in a secret, bloodless coup and established provisions for more parliaments with broader representation, for which he was later known as the Father of the House of Commons. When Henry III regained power in 1261, Simon de Montfort rallied forces for war, with victory at Lewes in 1264 and defeat and dismemberment in Evesham the year after. Although praised for supporting parliaments, he also earned a reputation for unleashing dark, violent forces in English politics and, infamously, his supporters murdered hundreds of Jewish people in London and elsewhere.With David Carpenter Professor of Medieval History at King’s College LondonLouise Wilkinson Professor of Medieval Studies at the University of LincolnAndSophie Thérèse Ambler Lecturer in Later Medieval British and European History at Lancaster UniversityProducer: Simon Tillotson

Melvyn Bragg and guests discuss the Roman poet Publius Ovidius Naso (43BC-17/18AD) who, as he described it, was destroyed by 'carmen et error', a poem and a mistake. His works have been preserved in greater number than any of the poets of his age, even Virgil, and have been among the most influential. The versions of many of the Greek and Roman myths we know today were his work, as told in his epic Metamorphoses and, together with his works on Love and the Art of Love, have inspired and disturbed readers from the time they were created. Despite being the most prominent poet in Augustan Rome at the time, he was exiled from Rome to Tomis on the Black Sea Coast where he remained until he died. It is thought that the 'carmen' that led to his exile was the Art of Love, Ars Amatoria, supposedly scandalising Augustus, but the 'error' was not disclosed.With Maria Wyke Professor of Latin at University College LondonGail Trimble Brown Fellow and Tutor in Classics at Trinity College at the University of OxfordAnd Dunstan Lowe Senior Lecturer in Latin Literature at the University of KentProducer: Simon Tillotson

Melvyn Bragg and guests discuss the treaties France entered into with the United States of America in 1778, to give open support to the USA in its revolutionary war against Britain and to promote French trade across the Atlantic. This alliance had profound consequences for all three. The French navy, in particular, played a decisive role in the Americans’ victory in their revolution, but the great cost of supporting this overseas war fell on French taxpayers, highlighting the need for reforms which in turn led to the French Revolution. Then, when France looked to its American ally for support in the new French revolutionary wars with Britain, Americans had to choose where their longer term interests lay, and they turned back from the France that had supported them to the Britain they had just been fighting, and France and the USA fell into undeclared war at sea.The image above is a detail of Bataille de Yorktown by Auguste Couder, with Rochambeau commanding the French expeditionary force in 1781With Frank Cogliano Professor of American History at the University of EdinburghKathleen Burk Professor Emerita of Modern and Contemporary History at University College LondonAndMichael Rapport Reader in Modern European History at the University of GlasgowProducer: Simon Tillotson

Melvyn Bragg and guests discuss the form of Christianity adopted by Ostrogoths in the 4th century AD, which they learned from Roman missionaries and from their own contact with the imperial court at Constantinople. This form spread to the Vandals and the Visigoths, who took it into Roman Spain and North Africa, and the Ostrogoths brought it deeper into Italy after the fall of the western Roman empire. Meanwhile, with the Roman empire in the east now firmly committed to the Nicene Creed not the Arian, the Goths and Vandals faced conflict or conversion, as Arianism moved from an orthodox view to being a heresy that would keep followers from heaven and delay the Second Coming for all.The image above is the ceiling mosaic of the Arian Baptistry in Ravenna, commissioned by Theodoric, ruler of the Ostrogothic Kingdom of Italy, around the end of the 5th centuryWithJudith Herrin Professor of Late Antique and Byzantine Studies, Emeritus, at King's College LondonRobin Whelan Lecturer in Mediterranean History at the University of LiverpoolAndMartin Palmer Visiting Professor in Religion, History and Nature at the University of WinchesterProducer: Simon Tillotson

Melvyn Bragg and guests discuss Laplace (1749-1827) who was a giant in the world of mathematics both before and after the French Revolution. He addressed one of the great questions of his age, raised but side-stepped by Newton: was the Solar System stable, or would the planets crash into the Sun, as it appeared Jupiter might, or even spin away like Saturn threatened to do? He advanced ideas on probability, long the preserve of card players, and expanded them out across science; he hypothesised why the planets rotate in the same direction; and he asked if the Universe was deterministic, so that if you knew everything about all the particles then you could predict the future. He also devised the metric system and reputedly came up with the name 'metre'.

Melvyn Bragg and guests discuss the conflict between Russia and Japan from February 1904 to September 1905, which gripped the world and had a profound impact on both countries. Wary of Russian domination of Korea, Japan attacked the Russian Fleet at Port Arthur and the ensuing war gave Russia a series of shocks, including the loss of their Baltic Fleet after a seven month voyage, which reverberated in the 1905 Revolution. Meanwhile Japan, victorious, advanced its goal of making Europe and America more wary in East Asia, combining rapid military modernisation and Samurai traditions when training its new peasant conscripts. The US-brokered peace failed to require Russia to make reparations, which became a cause of Japanese resentment towards the US.WithSimon Dixon The Sir Bernard Pares Professor of Russian History at University College LondonNaoko Shimazu Professor of Humanities at Yale NUS College, SingaporeAndOleg Benesch Reader in Modern History at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of the most influential economists from the age of Adam Smith and Thomas Malthus. Ricardo (1772 -1823) reputedly made his fortune at the Battle of Waterloo, and he made his lasting impact with his ideas on free trade. At a time when nations preferred to be self-sufficient, to produce all their own food and manufacture their own goods, and to find markets for export rather than import, Ricardo argued for free trade even with rivals for the benefit of all. He contended that existing economic policy unduly favoured landlords above all others and needed to change, and that nations would be less likely to go to war with their trading partners if they were more reliant on each other. For the last two hundred years, Ricardo’s Theory of Comparative Advantage in support of free trade has been developed and reinterpreted by generations of economists across the political spectrum.WithMatthew Watson Professor of Political Economy at the University of WarwickHelen Paul Lecturer in Economics and Economic History at the University of SouthamptonAndRichard Whatmore Professor of Modern History at the University of St Andrews and Co-Director of the St Andrews Institute of Intellectual HistoryProducer: Simon Tillotson

Melvyn Bragg and guests discuss Euripides' great tragedy, which was first performed in Athens in 405 BC when the Athenians were on the point of defeat and humiliation in a long war with Sparta. The action seen or described on stage was brutal: Pentheus, king of Thebes, is torn into pieces by his mother in a Bacchic frenzy and his grandparents condemned to crawl away as snakes. All this happened because Pentheus had denied the divinity of his cousin Dionysus, known to the audience as god of wine, theatre, fertility and religious ecstasy. The image above is a detail of a Red-Figure Cup showing the death of Pentheus (exterior) and a Maenad (interior), painted c. 480 BC by the Douris painter.

Melvyn Bragg and guests discuss the devastating mass extinctions of the Late Devonian Period, roughly 370 million years ago, when around 70 percent of species disappeared. Scientists are still trying to establish exactly what happened, when and why, but this was not as sudden as when an asteroid hits Earth. The Devonian Period had seen the first trees and soils and it had such a diversity of sea life that it’s known as the Age of Fishes, some of them massive and armoured, and, in one of the iconic stages in evolution, some of them moving onto land for the first time. One of the most important theories for the first stage of this extinction is that the new soils washed into oceans, leading to algal blooms that left the waters without oxygen and suffocated the marine life.

In this 900th edition of the programme, Melvyn Bragg and guests discuss one of the best known and most influential of the poems of the Romantic movement. Samuel Taylor Coleridge (1772-1834) wrote The Rime of the Ancient Mariner in 1798 after discussions with his friend Wordsworth. He refined it for the rest of his life, and it came to define him, a foreshadowing of his opium-addicted, lonely wandering and deepening sense of guilt. The poem tells of a sailor compelled to tell and retell the story of a terrible voyage in his youth, this time as guests are heading to a wedding party, where he stoppeth one of three.The image above is from Gustave Doré's illustration of the mariner's shooting of the albatross, for an 1877 German language edition of the poemWithSir Jonathan Bate Professor of Environmental Humanities at Arizona State UniversityTom Mole Professor of English Literature and Book History at the University of EdinburghAnd Rosemary Ashton Emeritus Quain Professor of English Language and Literature at University College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the man who, according to Machiavelli, was the last of the Five Good Emperors. Marcus Aurelius, 121 to 180 AD, has long been known as a model of the philosopher king, a Stoic who, while on military campaigns, compiled ideas on how best to live his life, and how best to rule. These ideas became known as his Meditations, and they have been treasured by many as an insight into the mind of a Roman emperor, and an example of how to avoid the corruption of power in turbulent times.The image above shows part of a bronze equestrian statue of Marcus Aurelius.With Simon Goldhill Professor of Greek Literature and Culture and Fellow of King’s College, CambridgeAngie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldAndCatharine Edwards Professor of Classics and Ancient History at Birkbeck, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the idea and experience of Christian pilgrimage in Europe from the 12th to the 15th centuries, which figured so strongly in the imagination of the age. For those able and willing to travel, there were countless destinations from Jerusalem, Rome and Santiago de Compostela to the smaller local shrines associated with miracles and relics of the saints. Meanwhile, for those unable or not allowed to travel there were journeys of the mind, inspired by guidebooks that would tell the faithful how many steps they could take around their homes to replicate the walk to the main destinations in Rome and the Holy Land, passing paintings of the places on their route. The image above is of a badge of St Thomas of Canterbury, worn by pilgrims who had journeyed to his shrine.WithMiri Rubin Professor of Medieval and Early Modern History at Queen Mary, University of LondonKathryn Rudy Professor of Art History at the University of St AndrewsAndAnthony Bale Professor of Medieval Studies and Dean of the School of Arts at Birkbeck, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of the most famous museum objects in the world, shown in the image above in replica, and dating from around 196 BC. It is a damaged, dark granite block on which you can faintly see three scripts engraved: Greek at the bottom, Demotic in the middle and Hieroglyphs at the top. Napoleon’s soldiers found it in a Mamluk fort at Rosetta on the Egyptian coast, and soon realised the Greek words could be used to unlock the hieroglyphs. It was another 20 years before Champollion deciphered them, becoming the first to understand the hieroglyphs since they fell out of use 1500 years before and so opening up the written culture of ancient Egypt to the modern age.With Penelope Wilson Associate Professor of Egyptian Archaeology at Durham UniversityCampbell Price Curator of Egypt and Sudan at the Manchester MuseumAndRichard Bruce Parkinson Professor of Egyptology and Fellow of The Queen’s College, University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of the outstanding French mathematicians and natural philosophers of the 18th Century, celebrated across Europe. Emilie du Châtelet, 1706-49, created a translation of Newton’s Principia from Latin into French that helped spread the light of mathematics on the emerging science, and her own book Institutions de Physique, with its lessons on physics, was welcomed as profound. She had the privileges of wealth and aristocracy, yet had to fight to be taken seriously as an intellectual in a world of ideas that was almost exclusively male.

Melvyn Bragg and guests discuss the Northumbrian man who, for 500 years, was the pre-eminent English saint, to be matched only by Thomas Becket after his martyrdom in 1170. Now at Durham, Cuthbert was buried first on Lindisfarne in 687AD, where monks shared vivid stories of his sanctifying miracles, his healing, and his power over nature, and his final tomb became a major site of pilgrimage. In his lifetime he was both hermit and kingmaker, bishop and travelling priest, and the many accounts we have of him, including two by Bede, tell us much of the values of those who venerated him so soon after his death.The image above is from a stained glass window in the south aisle of the nave in Durham Cathedral: 'St Cuthbert praying before his cell in the Farne Island'With Jane Hawkes Professor of Medieval Art History at the University of YorkSarah Foot The Regius Professor of Ecclesiastical History at the University of Oxford and Canon of Christ Church CathedralAnd John Hines Professor of Archaeology at Cardiff UniversityProducer: Simon Tillotson

Melvyn Bragg and guests discuss the plague that broke out in Constantinople 541AD, in the reign of Emperor Justinian. According to the historian Procopius, writing in Byzantium at the time, this was a plague by which the whole human race came near to being destroyed, embracing the whole world, and blighting the lives of all mankind. The bacterium behind the Black Death has since been found on human remains from that time, and the symptoms described were the same, and evidence of this plague has since been traced around the Mediterranean and from Syria to Britain and Ireland. The question of how devastating it truly was, though, is yet to be resolved.With John Haldon Professor of Byzantine History and Hellenic Studies Emeritus at Princeton UniversityRebecca Flemming Senior Lecturer in Classics at the University of CambridgeAndGreg Woolf Director of the Institute of Classical Studies, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss F Scott Fitzgerald’s finest novel, published in 1925, one of the great American novels of the twentieth century. It is told by Nick Carraway, neighbour and friend of the mysteriously wealthy Jay Gatsby. In the age of jazz and prohibition, Gatsby hosts lavish parties at his opulent home across the bay from Daisy Buchanan, in the hope she’ll attend one of them and they can be reunited. They were lovers as teenagers but she had given him up for a richer man who she soon married, and Gatsby is obsessed with winning her back.The image above is of Robert Redford as Gatsby in a scene from the film 'The Great Gatsby', 1974.

Melvyn Bragg and guests discuss solar eclipses, some of life’s most extraordinary moments, when day becomes night and the stars come out before day returns either all too soon or not soon enough, depending on what you understand to be happening. In ancient China, for example, there was a story that a dragon was eating the sun and it had to be scared away by banging pots and pans if the sun were to return. Total lunar eclipses are more frequent and last longer, with a blood moon coloured red like a sunrise or sunset. Both events have created the chance for scientists to learn something remarkable, from the speed of light, to the width of the Atlantic, to the roundness of Earth, to discovering helium and proving Einstein’s Theory of General Relativity.With Carolin Crawford Public Astronomer based at the Institute of Astronomy, University of Cambridge and a fellow of Emmanuel CollegeFrank Close Emeritus Professor of Physics at the University of OxfordAndLucie Green Professor of Physics and a Royal Society University Research Fellow at Mullard Space Science Laboratory at University College LondonProducers: Simon Tillotson and Julia Johnson

Melvyn Bragg and guests discuss Chairman Mao and the revolt he led within his own party from 1966, setting communists against each other, to renew the revolution that he feared had become too bourgeois and to remove his enemies and rivals. Universities closed and the students formed Red Guard factions to attack the 'four olds' - old ideas, culture, habits and customs - and they also turned on each other, with mass violence on the streets and hundreds of thousands of deaths. Over a billion copies of Chairman Mao’s Little Red Book were printed to support his cult of personality, before Mao himself died in 1976 and the revolution came to an end.The image above is of Red Guards, holding The Little Red Book, cheering Mao during a meeting to celebrate the Great Proletarian Cultural Revolution at Tiananmen Square, Beijing, August 1966 WithRana Mitter Professor of the History and Politics of Modern China and Fellow of St Cross College, University of OxfordSun Peidong Visiting Professor at the Center for International Studies at Sciences Po, ParisAndJulia Lovell Professor in Modern Chinese History and Literature at Birkbeck, University of LondonProduced by Simon Tillotson and Julia Johnson

Melvyn Bragg and guests discuss John Wesley (1703 - 1791) and the movement he was to lead and inspire. As a student, he was mocked for approaching religion too methodically and this jibe gave a name to the movement: Methodism. Wesley took his ideas out across Britain wherever there was an appetite for Christian revival, preaching in the open, especially the new industrial areas. Others spread Methodism too, such as George Whitefield, and the sheer energy of the movement led to splits within it, but it soon became a major force.

Melvyn Bragg and guests discuss the Portuguese poet Pessoa (1888-1935) who was largely unknown in his lifetime but who, in 1994, Harold Bloom included in his list of the 26 most significant western writers since the Middle Ages. Pessoa wrote in his own name but mainly in the names of characters he created, each with a distinctive voice and biography, which he called heteronyms rather than pseudonyms, notably Ricardo Reis, Alberto Caeiro, Álvaro de Campos and one who was closer to Pessoa's own identity, Bernardo Soares. Most of Pessoa's works were unpublished at his death, discovered in a trunk; as more and more was printed and translated, his fame and status grew.WithCláudia Pazos-Alonso Professor of Portuguese and Gender Studies and Senior Research Fellow at Wadham College, University of OxfordJuliet Perkins Visiting Senior Research Fellow in Portuguese Studies at King’s College LondonAndPaulo de Medeiros Professor of English and Comparative Literary Studies at the University of WarwickProducer: Simon Tillotson

Melvyn Bragg and guests discuss the notorious events off Jamaica in 1781 and their background. The British slave ship Zong, having sailed across the Atlantic towards Jamaica, threw 132 enslaved Africans from its human cargo into the sea to drown. Even for a slave ship, the Zong was overcrowded; those murdered were worth more to the ship dead than alive. The crew said there was not enough drinking water to go round and they had no choice, which meant they could claim for the deaths on insurance. The main reason we know of this atrocity now is that the owners took their claim to court in London, and the insurers were at first told to pay up as if the dead slaves were any other lost goods, not people. Abolitionists in Britain were scandalised: if courts treated mass murder in the slave trade as just another business transaction and not a moral wrong, the souls of the nation would be damned. But nobody was ever prosecuted.The image above is of sailors throwing slaves overboard, from Torrey's 'American Slave Trade', 1822WithVincent Brown Charles Warren Professor of American History and Professor of African and African American Studies at Harvard UniversityBronwen Everill Class of 1973 Lecturer in History and Fellow at Gonville & Caius College, University of CambridgeAnd Jake Subryan Richards Assistant Professor of History at the London School of EconomicsStudio production: Hannah Sander Producer: Simon Tillotson

Melvyn Bragg and guests discuss the great German artist Albrecht Dürer (1471-1528) who achieved fame throughout Europe for the power of his images. These range from his woodcut of a rhinoceros, to his watercolour of a young hare, to his drawing of praying hands and his stunning self-portraits such as that above (albeit here in a later monochrome reproduction) with his distinctive A D monogram. He was expected to follow his father and become a goldsmith, but found his own way to be a great artist, taking public commissions that built his reputation but did not pay, while creating a market for his prints, and he captured the timeless and the new in a world of great change.With Susan Foister Deputy Director and Curator of German Paintings at the National GalleryGiulia Bartrum Freelance art historian and Former Curator of German Prints and Drawings at the British MuseumAndUlinka Rublack Professor of Early Modern European History and Fellow of St John’s College, University of CambridgeStudio production: John Goudie

The philosopher Mary Astell (1666 – 1731) has been described as “the first English feminist”. Born in Newcastle in relatively poor circumstances in the aftermath of the upheaval of the English Civil War and the restoration of the monarchy, she moved to London as a young woman and became part of an extraordinary circle of intellectual and aristocratic women. In her pioneering publications, she argued that women’s education should be expanded, that men and women’s minds were the same and that no woman should be forced to marry against her will. Perhaps her most famous quotation is: “If all Men are born Free, why are all Women born Slaves?” Today, she is one of just a handful of female philosophers to be featured in the multi-volume Cambridge History of Political Thought. The image above is from Astell's "Reflections upon Marriage", 3rd edition, 1706, held by the British Library (Shelfmark 8415.bb.27)With:Hannah Dawson Senior Lecturer in the History of Ideas at King’s College LondonMark Goldie Professor Emeritus of Intellectual History at the University of CambridgeTeresa Bejan Associate Professor of Political Theory at Oriel College, University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss William Langland's poem, written around 1370, about a man called Will who fell asleep on the Malvern Hills and dreamed of Piers the Plowman. This was a time between the Black Death and The Peasants’ Revolt, when Christians wanted to save their souls but doubted how best to do it - and had to live with that uncertainty. Some call this the greatest medieval poem in English, one offering questions not answers, and it can be as unsettling now as it was then.WithLaura Ashe Professor of English Literature at Worcester College, University of OxfordLawrence Warner Professor of Medieval English at King’s College LondonAnd Alastair Bennett Lecturer in Medieval Literature at Royal Holloway, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss Maria Theresa (1717-1780) who inherited the Austrian throne in 1740 at the age of 23. Her neighbours circled like wolves and, within two months, Frederick the Great had seized one of her most prized lands, Silesia, exploiting her vulnerability. Yet over the next forty years through political reforms, alliances and marriages, she built Austria up into a formidable power, and she would do whatever it took to save the souls of her Catholic subjects, with a rigidity and intolerance that Joseph II, her son and heir, could not wait to challenge.

Melvyn Bragg and guests discuss Alan Turing (1912-1954) whose 1936 paper On Computable Numbers effectively founded computer science. Immediately recognised by his peers, his wider reputation has grown as our reliance on computers has grown. He was a leading figure at Bletchley Park in the Second World War, using his ideas for cracking enemy codes, work said to have shortened the war by two years and saved millions of lives. That vital work was still secret when Turing was convicted in 1952 for having a sexual relationship with another man for which he was given oestrogen for a year, or chemically castrated. Turing was to kill himself two years later. The immensity of his contribution to computing was recognised in the 1960s by the creation of the Turing Award, known as the Nobel of computer science, and he is to be the new face on the £50 note.WithLeslie Ann Goldberg Professor of Computer Science and Fellow of St Edmund Hall, University of OxfordSimon Schaffer Professor of the History of Science at the University of Cambridge and Fellow of Darwin CollegeAnd Andrew Hodges Biographer of Turing and Emeritus Fellow of Wadham College, OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss the idea that God created the universe and then left it for humans to understand by reason not revelation. Edward Herbert, 1583-1648 (pictured above) held that there were five religious truths: belief in a Supreme Being, the need to worship him, the pursuit of a virtuous life as the best form of worship, repentance, and reward or punishment after death. Others developed these ideas in different ways, yet their opponents in England's established Church collected them under the label of Deists, called Herbert the Father of Deism and attacked them as a movement, and Deist books were burned. Over time, reason and revelation found a new balance in the Church in England, while Voltaire and Thomas Paine explored the ideas further, leading to their re-emergence in the French and American Revolutions.With Richard Serjeantson Fellow and Lecturer in History at Trinity College, CambridgeKatie East Lecturer in History at Newcastle UniversityAnd Thomas Ahnert Professor of Intellectual History at the University of EdinburghProducer: Simon Tillotson

Melvyn Bragg and guests discuss one of Shakespeare’s greatest tragedies. When three witches prophesy that Macbeth will be king one day, he is not prepared to wait and almost the next day he murders King Duncan as he sleeps, a guest at Macbeth’s castle. From there we explore their brutal world where few boundaries are distinct – between safe and unsafe, friend and foe, real and unreal, man and beast – until Macbeth too is slaughtered.The image above shows Nicol Williamson as Macbeth in a 1983 BBC TV adaptation.With:Emma Smith Professor of Shakespeare Studies at Hertford College, University of OxfordKiernan Ryan Emeritus Professor of English Literature at Royal Holloway, University of LondonAnd David Schalkwyk, Professor of Shakespeare Studies and Director of Global Shakespeare at Queen Mary, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss ideas about the Stone Age people who created the extraordinary images found in caves around the world, from hand outlines to abstract symbols to the multicoloured paintings of prey animals at Chauvet and, as shown above, at Lascaux. In the 19th Century, it was assumed that only humans could have made these, as Neanderthals would have lacked the skills or imagination, but new tests suggest otherwise. How were the images created, were they meant to be for private viewing or public spaces, and what might their purposes have been? And, if Neanderthals were capable of creative work, in what ways were they different from humans? What might it have been like to experience the paintings, so far from natural light?

Melvyn Bragg and guests discuss Pericles (495-429BC), the statesman who dominated the politics of Athens for thirty years, the so-called Age of Pericles, when the city’s cultural life flowered, its democracy strengthened as its empire grew, and the Acropolis was adorned with the Parthenon. In 431 BC he gave a funeral oration for those Athenians who had already died in the new war with Sparta which has been celebrated as one of the greatest speeches of all time, yet within two years he was dead from a plague made worse by Athenians crowding into their city to avoid attacks. Thucydides, the historian, knew him and was in awe of him, yet few shared that view until the nineteenth century, when they found much in Pericles to praise, an example for the Victorian age.

In a programme first broadcast in May 2019, Melvyn Bragg and guests discuss Mary Shelley's (1797-1851) Gothic story of a Swiss natural philosopher, Victor Frankenstein, and the creature he makes from parts of cadavers and which he then abandons, horrified by his appearance, and never names. Rejected by all humans who see him, the monster takes his revenge on Frankenstein, killing those dear to him. Shelley started writing Frankenstein when she was 18, prompted by a competition she had with Byron and her husband Percy Shelley to tell a ghost story while they were rained in in the summer of 1816 at the Villa Diodati by Lake Geneva.The image of Mary Shelley, above, was first exhibited in 1840.WithKaren O'Brien Professor of English Literature at the University of OxfordMichael Rossington Professor of Romantic Literature at Newcastle UniversityAnd Jane Thomas Professor of Victorian and Early 20th Century Literature at the University of HullProducer: Simon TillotsonThis programme is a repeat

Melvyn Bragg and guests discuss the bonds that Scottish Presbyterians made between themselves and their monarchs in the 16th and 17th Centuries, to maintain their form of worship. These covenants bound James VI of Scotland to support Presbyterians yet when he became James I he was also expected to support episcopacy. That tension came to a head under Charles I who found himself on the losing side of a war with the Covenanters, who later supported Parliament before backing the future Charles II after he had pledged to support them. Once in power, Charles II failed to deliver the religious settlement the Covenanters wanted, and set about repressing them violently. Those who refused to renounce the covenants were persecuted in what became known as The Killing Times, as reflected in the image above.With Roger Mason Professor of Scottish History at the University of St AndrewsLaura Stewart Professor of Early Modern British History at the University of YorkAndScott Spurlock Professor of Scottish and Early Modern Christianities at the University of GlasgowProducer: Simon Tillotson

Melvyn Bragg and guests discuss the theoretical physicist Dirac (1902-1984), whose achievements far exceed his general fame. To his peers, he was ranked with Einstein and, when he moved to America in his retirement, he was welcomed as if he were Shakespeare. Born in Bristol, he trained as an engineer before developing theories in his twenties that changed the understanding of quantum mechanics, bringing him a Nobel Prize in 1933 which he shared with Erwin Schrödinger. He continued to make deep contributions, bringing abstract maths to physics, beyond predicting anti-particles as he did in his Dirac Equation.With Graham Farmelo Biographer of Dirac and Fellow at Churchill College, CambridgeValerie Gibson Professor of High Energy Physics at the University of Cambridge and Fellow of Trinity CollegeAndDavid Berman Professor of Theoretical Physics at Queen Mary University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the origins of horses, from their dog sized ancestors to their proliferation in the New World until hunted to extinction, their domestication in Asia and their development since. The genetics of the modern horse are the most studied of any animal, after humans, yet it is still uncertain why they only have one toe on each foot when their wider family had more, or whether speed or stamina has been more important in their evolution. What is clear, though, is that when humans first chose to ride horses, as well as eat them, the future of both species changed immeasurably.With Alan Outram Professor of Archaeological Science at the University of ExeterChristine Janis Honorary Professor in Palaeobiology at the University of Bristol and Professor Emerita in Ecology and Evolutionary Biology at Brown UniversityAnd John Hutchinson Professor in Evolutionary Biomechanics at the Royal Veterinary CollegeProducer: Simon Tillotson

Melvyn Bragg and guests discuss the debate in Valladolid, Spain in 1550, over Spanish rights to enslave the native peoples in the newly conquered lands. Bartolomé de Las Casas (pictured above), the Bishop of Chiapas, Mexico, was trying to end the encomienda system in which those who now owned the land could also take the people in forced labour. Juan Gines Sepulveda, a philosopher, argued for the colonists' property rights over people, asserting that some native Americans were 'natural slaves' as defined by Aristotle. Valladolid became seen as the first open attempt by European colonists to discuss the ethics of slavery, and Las Casas became known as 'Saviour of the Indians' and an advocate for human rights, although for some time he argued that African slaves be imported to do the work in place of the native people, before repenting.With Caroline Dodds Pennock Senior Lecturer in International History at the University of SheffieldJohn Edwards Faculty Fellow in Spanish at the University of OxfordAnd Julia McClure Lecturer in Late Medieval and Early Modern Global History at the University of GlasgowProducer: Simon Tillotson

Melvyn Bragg and guests discuss the great Roman military disaster of 9 AD when Germanic tribes under Arminius ambushed and destroyed three legions under Varus. According to Suetonius, emperor Augustus hit his head against the wall when he heard the news, calling on Varus to give him back his legions. The defeat ended Roman expansion east of the Rhine. Victory changed the development of the Germanic peoples, both in the centuries that followed and in the nineteenth century when Arminius, by then known as Herman, became a rallying point for German nationalism.With Peter Heather Professor of Medieval History at King’s College LondonEllen O'Gorman Senior Lecturer in Classics at the University of BristolAndMatthew Nicholls Fellow and Senior Tutor at St John’s College, OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss the works and life of one of the most popular writers in Europe in C19th, Amantine Lucile Aurore Dupin (1804-1876) who wrote under the name George Sand. When she wrote her first novel under that name, she referred to herself as a man. This was in Indiana (1832), which had the main character breaking away from her unhappy marriage. It made an immediate impact as it overturned the social conventions of the time and it drew on her own early marriage to an older man, Casimir Dudevant. Once Sand's identity was widely known, her works became extremely popular in French and in translation, particularly her rural novels, outselling Hugo and Balzac in Britain, perhaps buoyed by an interest in her personal life, as well as by her ideas on the rights and education of women and strength of her writing.With Belinda Jack Fellow and Tutor in French at Christ Church, University of OxfordAngela Ryan Senior Lecturer in French at University College CorkAndNigel Harkness Pro-Vice-Chancellor for Humanities and Social Sciences and Professor of French at Newcastle UniversityProducer: Simon Tillotson

Melvyn Bragg and guests discuss Alcuin of York, c735-804AD, who promoted education as a goal in itself, and had a fundamental role in the renaissance at Charlemagne's court. He wrote poetry and many letters, hundreds of which survive and provide insight into his life and times. He was born in or near York and spent most of his life in Northumbria before accepting an invitation to Charlemagne's court in Aachen. To this he brought Anglo-Saxon humanism, encouraging a broad liberal education for itself and the better to understand Christian doctrine. He left to be abbot at Marmoutier, Tours, where the monks were developing the Carolingian script that influenced the Roman typeface. The image above is Alcuin’s portrait, found in a copy of the Bible made at his monastery in Tours during the rule of his successor Abbot Adalhard (834–843). Painted in red on gold leaf, it shows Alcuin with a tonsure and a halo, signifying respect for his memory at the monastery where he had died in 804. His name and rank are spelled out alongside: Alcvinvs abba, ‘Alcuin the abbot’. It is held at the Staatsbibliothek Bamberg -Kaiser-Heinrich-Bibliothek - Msc.Bibl.1,fol.5v (photo by Gerald Raab).With Joanna Story Professor of Early Medieval History at the University of LeicesterAndy Orchard Rawlinson and Bosworth Professor of Anglo-Saxon at the University of Oxford and a fellow of Pembroke CollegeAnd Mary Garrison Lecturer in History at the Centre for Medieval Studies at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss the flow of particles from the outer region of the Sun which we observe in the Northern and Southern Lights, interacting with Earth's magnetosphere, and in comet tails that stream away from the Sun regardless of their own direction. One way of defining the boundary of the solar system is where the pressure from the solar wind is balanced by that from the region between the stars, the interstellar medium. Its existence was suggested from the C19th and Eugene Parker developed the theory of it in the 1950s and it has been examined and tested by a series of probes in C20th up to today, with more planned.With Andrew Coates Professor of Physics and Deputy Director in charge of the Solar System at the Mullard Space Science Laboratory, University College LondonHelen Mason OBE Reader in Solar Physics at the Department of Applied Mathematics and Theoretical Physics, University of Cambridge, Fellow at St Edmund's CollegeAndTim Horbury Professor of Physics at Imperial College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the siege of Paris during the Franco-Prussian war and the social unrest that followed, as the French capital was cut off from the rest of the country and food was scarce. When the French government surrendered Paris to the Prussians, power gravitated to the National Guard in the city and to radical socialists, and a Commune established in March 1871 with the red flag replacing the trilcoleur. The French government sent in the army and, after bloody fighting, the Communards were defeated by the end of May 1871.The image above is from an engraving of the fire in the Tuileries Palace, May 23, 1871With Karine Varley Lecturer in French and European History at the University of StrathclydeRobert Gildea Professor of Modern History at the University of OxfordAndJulia Nicholls Lecturer in French and European Studies at King’s College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss Catullus (c84-c54 BC) who wrote some of the most sublime poetry in the late Roman Republic, and some of the most obscene. He found a new way to write about love, in poems to the mysterious Lesbia, married and elusive, and he influenced Virgil and Ovid and others, yet his explicit poems were to blight his reputation for a thousand years. Once the one surviving manuscript was discovered in the Middle Ages, though, anecdotally as a plug in a wine butt, he inspired Petrarch and the Elizabethan poets, as he continues to inspire many today.The image above is of Lesbia and her Sparrow, 1860, artist unknownWithGail Trimble Brown Fellow and Tutor in Classics at Trinity College at the University of OxfordSimon Smith Reader in Creative Writing at the University of Kent, poet and translator of CatullusandMaria Wyke Professor of Latin at University College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the discovery in 1922 of Tutankhamun's 3000 year old tomb and its impact on the understanding of ancient Egypt, both academic and popular. The riches, such as the death mask above, were spectacular and made the reputation of Howard Carter who led the excavation. And if the astonishing contents of the tomb were not enough, the drama of the find and the control of how it was reported led to a craze for 'King Tut' that has rarely subsided and has enthused and sometimes confused people around the world, seeking to understand the reality of Tutankhamun's life and times.With Elizabeth Frood Associate Professor of Egyptology, Director of the Griffith Institute and Fellow of St Cross at the University of OxfordChristina Riggs Professor of the History of Visual Culture at Durham University and a Fellow of All Souls College, OxfordAnd John Taylor Curator at the Department of Egypt and Sudan at the British MuseumProducer: Simon Tillotson

Melvyn Bragg and guests discuss the life and poetry of WH Auden (1907-1973) up to his departure from Europe for the USA in 1939. As well as his personal life, he addressed suffering and confusion, and the moral issues that affected the wider public in the 1930s and tried to unpick what was going wrong in society and to understand those times. He witnessed the rise of totalitarianism in the austerity of that decade, travelling through Germany to Berlin, seeing Spain in the Civil War and China during its wars with Japan, often collaborating with Christopher Isherwood. In his lifetime his work attracted high praise and intense criticism, and has found new audiences in the fifty years since his death, sometimes taking literally what he meant ironically.

Melvyn Bragg and guests discuss the history and social impact of coffee. From its origins in Ethiopia, coffea arabica spread through the Ottoman Empire before reaching Western Europe where, in the 17th century, coffee houses were becoming established. There, caffeinated customers stayed awake for longer and were more animated, and this helped to spread ideas and influence culture. Coffee became a colonial product, grown by slaves or indentured labour, with coffea robusta replacing arabica where disease had struck, and was traded extensively by the Dutch and French empires; by the 19th century, Brazil had developed into a major coffee producer, meeting demand in the USA that had grown on the waggon trails.

Melvyn Bragg and guests discuss T.E. Lawrence (1888 – 1935), better known as Lawrence of Arabia, a topic drawn from over 1200 suggestions for our Listener Week 2019. Although Lawrence started as an archaeologist in the Middle East, when World War I broke out he joined the British army and became an intelligence officer. His contact with a prominent Arab leader, Sharif Hussein, made him sympathetic to Hussein’s cause and during the Arab Revolt of 1916 he not only served the British but also the interests of Hussein. After the war he was dismayed by the peace settlement and felt that the British had broken an assurance that Sharif Hussein would lead a new Arab kingdom. Lawrence was made famous by the work of Lowell Thomas, whose film of Lawrence drew huge audiences in 1919, which led to his own book Seven Pillars of Wisdom and David Lean’s 1962 film with Peter O'Toole.In previous Listener Weeks, we've discussed Kafka's The Trial, The Voyages of Captain Cook, Garibaldi and the Risorgimento, Moby Dick and The Thirty Years War.With Hussein Omar Lecturer in Modern Global History at University College Dublin Catriona Pennell Associate Professor of Modern History and Memory Studies at the University of ExeterNeil Faulkner Director of Military History Live and Editor of the magazine Military History MattersProducer: Simon Tillotson

Melvyn Bragg and guests discuss the life and ideas of Li Shizhen (1518-1593) whose compendium of natural medicines is celebrated in China as the most complete survey of natural remedies of its time. He trained as a doctor and worked at the Ming court before spending almost 30 years travelling in China, inspecting local plants and animals for their properties, trying them out on himself and then describing his findings in his Compendium of Materia Medica or Bencao Gangmu, in 53 volumes. He's been called the uncrowned king of Chinese naturalists, and became a scientific hero in the 20th century after the revolution.With Craig Clunas Professor Emeritus in the History of Art at the University of OxfordAnne Gerritsen Professor in History at the University of WarwickAnd Roel Sterckx Joseph Needham Professor of Chinese History at the University of CambridgeProducer: Simon Tillotson

Melvyn Bragg and guests discuss the most powerful woman in the Crusader states in the century after the First Crusade. Melisende (1105-61) was born and raised after the mainly Frankish crusaders had taken Jerusalem from the Fatimids, and her father was King of Jerusalem. She was married to Fulk from Anjou, on the understanding they would rule together, and for 30 years she vied with him and then their son as they struggled to consolidate their Frankish state in the Holy Land. The image above is of the coronation of Fulk with Melisende, from Livre d'Eracles, Guillaume de Tyr (1130?-1186) Source: Bibliothèque nationale de France With Natasha Hodgson Senior Lecturer in Medieval History and Director of the Centre for the Study of Religion and Conflict at Nottingham Trent UniversityKatherine Lewis Senior Lecturer in History at the University of Huddersfieldand Danielle Park Visiting Lecturer at Royal Holloway, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the novel written by Dostoevsky and published in 1866, in which Raskolnikov, a struggling student, justifies his murder of two women, as his future is more valuable than their lives. He thinks himself superior, above the moral laws that apply to others. The police have little evidence against him but trust him to confess, once he cannot bear the mental torture of his crime - a fate he cannot avoid, any more than he can escape from life in St Petersburg and his personal failures.The image above is from a portrait of Dostoevsky by Vasili Perov, 1872.WithSarah Hudspith Associate Professor in Russian at the University of LeedsOliver Ready Lecturer in Russian at the University of Oxford, Research Fellow at St Antony’s College and a translator of this novelAnd Sarah Young Associate Professor in Russian at the School of Slavonic and East European Studies, University College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the 1691 peace treaty that ended the Williamite War in Ireland, between supporters of the deposed King James II and the forces of William III and his allies. It followed the battles at Aughrim and the Boyne and sieges at Limerick, and led to the disbanding of the Jacobite army in Ireland, with troops free to follow James to France for his Irish Brigade. The Catholic landed gentry were guaranteed rights on condition of swearing loyalty to William and Mary yet, while some Protestants thought the terms too lenient, it was said the victors broke those terms before the ink was dry.The image above is from British Battles on Land and Sea, Vol. I, by James Grant, 1880, and is meant to show Irish troops leaving Limerick as part of The Flight of the Wild Geese - a term used for soldiers joining continental European armies from C16th-C18th.With Jane Ohlmeyer Chair of the Irish Research Council and Erasmus Smith’s Professor of Modern History at Trinity College DublinDr Clare Jackson Senior Tutor, Trinity Hall, and Faculty of History, University of Cambridgeand Thomas O'Connor Professor of History at Maynooth UniversityProducer: Simon Tillotson

Melvyn Bragg and guests discuss what happens when parents from different species have offspring, despite their genetic differences. In some cases, such as the zebra/donkey hybrid in the image above, the offspring are usually infertile but in others the genetic change can lead to new species with evolutionary advantages. Hybrids can occur naturally, yet most arise from human manipulation and Darwin's study of plant and animal domestication informed his ideas on natural selection.With Sandra Knapp Tropical Botanist at the Natural History MuseumNicola Nadeau Lecturer in Evolutionary Biology at the University of SheffieldAndSteve Jones Senior Research Fellow in Genetics at University College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the work of the man who, in his lifetime, was called The Caledonian Bard and whose fame and influence was to spread around the world. Burns (1759-1796) was born in Ayrshire and his work as a tenant farmer earned him the label The Ploughman Poet, yet it was the quality of his verse that helped his reputation endure and grow. His work inspired other Romantic poets and his personal story and ideas combined with that, giving his poems a broad strength and appeal - sung by revolutionaries and on Mao's Long March, as well as on New Year's Eve and at Burns Suppers.WithRobert Crawford Professor of Modern Scottish Literature and Bishop Wardlaw Professor of Poetry at the University of St AndrewsFiona Stafford Professor of English at the University of Oxfordand Murray Pittock Bradley Professor of English Literature and Pro Vice Principal at the University of GlasgowProducer: Simon Tillotson

Melvyn Bragg and guests discuss the ideas explored in HG Wells' novella, published in 1895, in which the Time Traveller moves forward to 802,701 AD. There he finds humanity has evolved into the Eloi and Morlocks, where the Eloi are small but leisured fruitarians and the Morlocks live below ground, carry out the work and have a different diet. Escaping the Morlocks, he travels millions of years into the future, where the environment no longer supports humanity.The image above is from a painting by Anton Brzezinski of a scene from The Time Machine, with the Time Traveller meeting the EloiWith Simon Schaffer Professor of History of Science at Cambridge UniversityAmanda Rees Historian of science at the University of YorkAndSimon James Professor in the Department of English Studies at Durham UniversityProducer: Simon Tillotson

Melvyn Bragg and guests discuss the ideas of Jean-Jacques Rousseau (1712-1778) on the education of children, as set out in his novel or treatise Emile, published in 1762. He held that children are born with natural goodness, which he sought to protect as they developed, allowing each to form their own conclusions from experience, avoiding the domineering influence of others. In particular, he was keen to stop infants forming the view that human relations were based on domination and subordination. Rousseau viewed Emile as his most imporant work, and it became very influential. It was also banned and burned, and Rousseau was attacked for not following these principles with his own children, who he abandoned, and for proposing a subordinate role for women in this scheme.The image above is of Emile playing with a mask on his mother's lap, from a Milanese edition published in 1805.With Richard Whatmore Professor of Modern History at the University of St Andrews and Co-Director of the St Andrews Institute of Intellectual HistoryCaroline Warman Professor of French Literature and Thought at Jesus College, Oxfordand Denis McManus Professor of Philosophy at the University of SouthamptonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the work and ideas of Dorothy Crowfoot Hodgkin (1910-1994), awarded the Nobel Prize in Chemistry in 1964 for revealing the structures of vitamin B12 and penicillin and who later determined the structure of insulin. She was one of the pioneers of X-ray crystallography and described by a colleague as 'a crystallographers' crystallographer'. She remains the only British woman to have won a Nobel in science, yet rejected the idea that she was a role model for other women, or that her career was held back because she was a woman. She was also the first woman since Florence Nightingale to receive the Order of Merit, and was given the Lenin Peace Prize in recognition of her efforts to bring together scientists from the East and West in pursuit of nuclear disarmament.With Georgina Ferry Science writer and biographer of Dorothy HodgkinJudith Howard Professor of Chemistry at Durham UniversityandPatricia Fara Fellow of Clare College, CambridgeProducer: Simon Tillotson

Melvyn Bragg and guests discuss the ideas developed by the Anglican priest John Nelson Darby (1800-1882), drawn from his reading of scripture, in which Jesus would suddenly take His believers up into the air, and those left behind would suffer on Earth until He returned with His church to rule for a thousand years before Final Judgement. Some believers would look for signs that civilization was declining, such as wars and natural disasters, or for new Roman Empires that would harbour the Antichrist, and from these predict the time of the Rapture. Darby helped establish the Plymouth Brethren, and later his ideas were picked up in the Scofield Reference Bible (1909) and soon became influential, particularly in the USA.

Melvyn Bragg and guests discuss how, in September 1812, Napoleon captured Moscow and waited a month for the Russians to meet him, to surrender and why, to his dismay, no-one came. Soon his triumph was revealed as a great defeat; winter was coming, supplies were low; he ordered his Grande Armée of six hundred thousand to retreat and, by the time he crossed back over the border, desertion, disease, capture, Cossacks and cold had reduced that to twenty thousand. Napoleon had shown his weakness; his Prussian allies changed sides and, within eighteen months they, the Russians and Austrians had captured Paris and the Emperor was exiled to Elba.WithJanet Hartley Professor Emeritus of International History, LSEMichael Rowe Reader in European History, King’s College LondonAndMichael Rapport Reader in Modern European History, University of GlasgowProducer: Simon Tillotson

Melvyn Bragg and guests discuss the Spanish poet and playwright Federico Garcia Lorca (1898-1936), author of Blood Wedding, Yerma and The House of Bernarda Alba, who mixed the traditions of Andalusia with the avant-garde. He found his first major success with his Gypsy Ballads, although Dali, once his close friend, mocked him for these, accusing Lorca of being too conservative. He preferred performing his poems to publishing them, and his plays marked a revival in Spanish theatre. He was captured and killed by Nationalist forces at the start of the Civil War, his body never recovered, and it's been suggested this was punishment for his politics and for being openly gay. He has since been seen as the most important Spanish playwright and poet of the last century.WithMaria Delgado Professor of Creative Arts at the Royal Central School of Speech and Drama, University of LondonFederico Bonaddio Reader in Modern Spanish at King’s College LondonAndSarah Wright Professor of Hispanic Studies and Screen Arts at Royal Holloway, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the people, plants and animals once living on land now under the North Sea, now called Doggerland after Dogger Bank, inhabited up to c7000BC or roughly 3000 years before the beginnings of Stonehenge. There are traces of this landscape at low tide, such as the tree stumps at Redcar (above); yet more is being learned from diving and seismic surveys which are building a picture of an ideal environment for humans to hunt and gather, with rivers and wooded hills. Rising seas submerged this land as glaciers melted, and the people and animals who lived there moved to higher ground, with the coasts of modern-day Britain on one side and Denmark, Germany, The Netherlands, Belgium and France on the other.With Vince Gaffney Anniversary Professor of Landscape Archaeology at the University of BradfordCarol Cotterill Marine Geoscientist at the British Geological SurveyAndRachel Bynoe Lecturer in Archaeology at the University of SouthamptonProducer: Simon Tillotson

Melvyn Bragg and guests discuss why Athenians decided to send a fast ship to Lesbos in 427BC, rowing through the night to catch one they sent the day before. That earlier ship had instructions to kill all adult men in Mytilene, after their unsuccessul revolt against Athens, as a warning to others. The later ship had orders to save them, as news of their killing would make others fight to the death rather than surrender. Thucydides retells this in his History of the Peloponnesian War as an example of Athenian democracy in action, emphasising the right of Athenians to change their minds in their own interests, even when a demagogue argued they were bound by their first decision.

Melvyn Bragg and guests discuss how the people of Cusco, in modern Peru, established an empire along the Andes down to the Pacific under their supreme leader Pachacuti. Before him, their control grew slowly from C13th and was at its peak after him when Pizarro arrived with his Conquistadors and captured their empire for Spain in 1533. The image, above, is of Machu Picchu which was built for emperor Pachacuti as an estate in C15th.

Melvyn Bragg and guests discuss the range, depth and style of Browne (1605-82) , a medical doctor whose curious mind drew him to explore and confess his own religious views, challenge myths and errors in science and consider how humans respond to the transience of life. His Religio Medici became famous throughout Europe and his openness about his religion, in that work, was noted as rare when others either kept quiet or professed orthodox views. His Pseudodoxia Epidemica challenged popular ideas, whether about the existence of mermaids or if Adam had a navel, and his Hydriotaphia or Urn Burial was a meditation on what matters to humans when handling the dead. In 1923, Virginia Woolf wrote, "Few people love the writings of Sir Thomas Browne, but those that do are the salt of the earth." He also contributed more words to the English language than almost anyone, such as electricity, indigenous, medical, ferocious, carnivorous ambidextrous and migrant.With Claire Preston Professor of Renaissance Literature at Queen Mary University of LondonJessica Wolfe Professor of English and Comparative Literature at the University of North Carolina at Chapel HillAndKevin Killeen Professor of English at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss the impact of Grant's presidency on Americans in the years after the Civil War in which he, with Lincoln, had led the Union Army to victory. His predecessor, Andrew Johnson, was prepared to let the Southern States decide for themselves which rights to allow freed slaves; Grant supported equal rights, and he used troops and Enforcement Acts to defeat the Ku klux Klan which was violently suppressing African Americans. In later years Grant was remembered mainly for the corruption scandals under his terms of office, and for his failure to support or protect Native Americans, but in more recent decades his support for reconstruction has prompted a reassessement.WithErik Mathisen Lecturer in US History at the University of KentSusan-Mary Grant Professor of American History at Newcastle UniversityandRobert Cook Professor of American History at the University of SussexProducer: Simon Tillotson

Melvyn Bragg and guests discuss how scientists sought to understand the properties of gases and the relationship between pressure and volume, and what that search unlocked. Newton theorised that there were static particles in gases that pushed against each other all the harder when volume decreased, hence the increase in pressure. Those who argued that molecules moved, and hit each other, were discredited until James Maxwell and Ludwig Boltzmann used statistics to support this kinetic theory. Ideas about atoms developed in tandem with this, and it came as a surprise to scientists in C20th that the molecules underpinning the theory actually existed and were not simply thought experiments.

Melvyn Bragg and guests discuss the French philosopher Henri Bergson (1859-1941) and his ideas about human experience of time passing and how that differs from a scientific measurement of time, set out in his thesis on 'Time and Free Will' in 1889. He became famous in France and abroad for decades, rivalled only by Einstein and, in the years after the Dreyfus Affair, was the first ever Jewish member of the Académie Française. It's thought his work influenced Proust and Woolf, and the Cubists. He died in 1941 from a cold which, reputedly, he caught while queuing to register as a Jew, refusing the Vichy government's offer of exemption.WithKeith Ansell-Pearson Professor of Philosophy at the University of WarwickEmily Thomas Assistant Professor in Philosophy at Durham UniversityAnd Mark Sinclair Reader in Philosophy at the University of RoehamptonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the most destructive riots in London's history, which reached their peak on 7th June 1780 as troops fired on the crowd outside the Bank of England. The leader was Lord George Gordon, head of the Protestant Association, who objected to the relaxing of laws against Catholics. At first the protest outside Parliament was peaceful but, when Gordon's petition failed to persuade the Commons, rioting continued for days until the military started to shoot suspects in the street. It came as Britain was losing the war to hold on to colonies in North America.The image above shows a crowd setting fire to Newgate Prison and freeing prisoners by the authority of 'His Majesty, King Mob.'WithIan Haywood Professor of English at the University of RoehamptonCatriona Kennedy Senior Lecturer in Modern British and Irish History and Director of the Centre for Eighteenth Century Studies at the University of Yorkand Mark Knights Professor of History at the University of WarwickProducer: Simon Tillotson

Melvyn Bragg and guests discuss the life of Nero (37-68 AD) who became Emperor at the age of 16. At first he was largely praised for his generosity yet became known for his debauched lifestyle, with allegations he started the Fire of Rome, watching the flames as he played the lyre. Christians saw him as their persecutor, an anti-Christ, and the number of the Beast in the Book of Revelation was thought to indicate Nero. He had confidence in his own artistry, took up acting (which then had a very low status) and, as revolts in the empire grew, killed himself after the Senate condemned him to die as a slave, on a cross.

Melvyn Bragg and guests discuss one of Shakespeare's most popular works, written c1595 in the last years of Elizabeth I. It is a comedy of love and desire and their many complications as well as their simplicity, and a reflection on society's expectations and limits. It is also a quiet critique of Elizabeth and her vulnerability and on the politics of the time, and an exploration of the power of imagination.With Helen Hackett Professor of English Literature and Leverhulme Research Fellow at University College LondonTom Healy Professor of Renaissance Studies at the University of Sussexand Alison Findlay Professor of Renaissance Drama at Lancaster University and Chair of the British Shakespeare AssociationProducer: Simon Tillotson

Melvyn Bragg and guests discuss theories about the origins of teeth in vertebrates, and what we can learn from sharks in particular and their ancestors. Great white sharks can produce up to 100,000 teeth in their lifetimes. For humans, it is closer to a mere 50 and most of those have to last from childhood. Looking back half a billion years, though, the ancestors of sharks and humans had no teeth in their mouths at all, nor jaws. They were armoured fish, sucking in their food. The theory is that either their tooth-like scales began to appear in mouths as teeth, or some of their taste buds became harder. If we knew more about that, and why sharks can regenerate their teeth, then we might learn how humans could grow new teeth in later lives.

Melvyn Bragg and guests discuss why the potato crop failures in the 1840s had such a catastrophic impact in Ireland. It is estimated that one million people died from disease or starvation after the blight and another two million left the country within the decade. There had been famines before, but not on this scale. What was it about the laws, attitudes and responses that made this one so devastating?The image above is from The Illustrated London News, Dec. 29, 1849, showing a scalp or shelter, "a hole, surrounded by pools, and three sides of the scalp were dripping with water, which ran in small streams over the floor and out by the entrance. The poor inhabitants said they would be thankful if the landlord would leave them there, and the Almighty would spare their lives. Its principal tenant is Margaret Vaughan."With Cormac O'Grada Professor Emeritus in the School of Economics at University College DublinNiamh Gallagher University Lecturer in Modern British and Irish History at the University of CambridgeAnd Enda Delaney Professor of Modern History and School Director of Research at the University of EdinburghProducer: Simon Tillotson

Melvyn Bragg and guests discuss the effective partition of England in the 880s after a century of Viking raids, invasions and settlements. Alfred of Wessex, the surviving Anglo-Saxon king and Guthrum, a Danish ruler, had fought each other to a stalemate and came to terms, with Guthrum controlling the land to the east (once he had agreed to convert to Christianity). The key strategic advantage the invaders had was the Viking ships which were far superior and enabled them to raid from the sea and up rivers very rapidly. Their Great Army had arrived in the 870s, conquering the kingdom of Northumbria and occupying York. They defeated the king of Mercia and seized part of his land. They killed the Anglo-Saxon king of East Anglia and gained control of his territory. It was only when a smaller force failed to defeat Wessex that the Danelaw came into being, leaving a lasting impact on the people and customs of that area.With Judith Jesch Professor of Viking Studies at the University of NottinghamJohn Hines Professor of Archaeology at Cardiff UniversityAndJane Kershaw ERC Principal Investigator in Archaeology at the University of OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss the life and works of Hopkins (1844-89), a Jesuit priest who at times burned his poems and at others insisted they should not be published. His main themes are how he, nature and God relate to each other. His friend Robert Bridges preserved Hopkins' poetry and, once printed in 1918, works such as The Windhover, Pied Beauty and As Kingfishers Catch Fire were celebrated for their inventiveness and he was seen as a major poet, perhaps the greatest of the Victorian age.

Melvyn Bragg and guests discuss what it means to be oneself, a question explored by philosophers from Aristotle to the present day, including St Augustine, Kierkegaard, Heidegger and Sartre. In Hamlet, Polonius said 'To thine own self be true', but what is the self, and what does it mean to be true to it, and why should you be true? To Polonius, if you are true to yourself, ‘thou canst not be false to any man’ - but with the rise of the individual, authenticity became a goal in itself, regardless of how that affected others. Is authenticity about creating yourself throughout your life, or fulfilling the potential with which you were born, connecting with your inner child, or something else entirely? What are the risks to society if people value authenticity more than morality - that is, if the two are incompatible? The image above is of Sartre, aged 8 months, perhaps still connected to his inner child.With Sarah Richmond Associate Professor in Philosophy at University College LondonDenis McManus Professor of Philosophy at the University of Southamptonand Irene McMullin Senior Lecturer in Philosophy at the University of EssexProducer: Simon Tillotson

Melvyn Bragg and guests discuss the impact on the British Isles of William Cecil, 1st Baron Burghley, the most poweful man in the court of Elizabeth I. He was both praised and attacked for his flexibility, adapting to the reigns of Protestant and Catholic monarchs and, under Elizabeth, his goal was to make England strong, stable and secure from attack from its neighbours. He sought control over Ireland and persuaded Elizabeth that Mary Queen of Scots must die, yet often counselled peace rather than war in the interests of prosperity.

Melvyn Bragg and guests discuss the life, works, context and legacy of Antarah (525-608AD), the great poet and warrior. According to legend, he was born a slave; his mother was an Ethiopian slave, his father an elite Arab cavalryman. Antarah won his freedom in battle and loved a woman called Abla who refused him, and they were later celebrated in the saga of Antar and Abla. One of Antarah's poems was so esteemed in pre-Islamic Arabia that it is believed it was hung up on the wall of the Kaaba in Mecca.

Melvyn Bragg and guests discuss how members of the same species send each other invisible chemical signals to influence the way they behave. Pheromones are used by species across the animal kingdom in a variety of ways, such as laying trails to be followed, to raise the alarm, to scatter from predators, to signal dominance and to enhance attractiveness and, in honey bees, even direct development into queen or worker. The image above is of male and female ladybirds that have clustered together in response to pheromones.

Melvyn Bragg and guests discuss how artists from the Middle Ages onwards have been inspired by the Bible story of the widow who killed an Assyrian general who was besieging her village, and so saved her people from his army and from his master Nebuchadnezzar. A symbol of a woman's power and the defiance of political tyranny, the image of Judith has been sculpted by Donatello, painted on the ceiling of the Sistine Chapel and, in the case of Caravaggio, Liss and Artemisia Gentileschi, been shown with vivid, disturbing detail. What do these interpretations reveal of the attitudes to power and women in their time, and of the artists' own experiences?

Melvyn Bragg and guests discuss the remarkable achievement of Aristotle (384-322BC) in the realm of biological investigation, for which he has been called the originator of the scientific study of life. Known mainly as a philosopher and the tutor for Alexander the Great, who reportedly sent him animal specimens from his conquests, Aristotle examined a wide range of life forms while by the Sea of Marmara and then on the island of Lesbos. Some ideas, such as the the spontaneous generation of flies, did not survive later scrutiny, yet his influence was extraordinary and his work was unequalled until the early modern period.The image above is of the egg and embryo of a dogfish, one of the animals Aristotle described accurately as he recorded their development.WithArmand Leroi Professor of Evolutionary Development Biology at Imperial College LondonMyrto Hatzimichali Lecturer in Classics at the University of CambridgeAndSophia Connell Lecturer in Philosophy at Birkbeck, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the life of the Welsh nobleman, also known as Owen Glendower, who began a revolt against Henry IV in 1400 which was at first very successful. Glyndwr (c1359-c1415) adopted the title Prince of Wales and established a parliament and his own foreign policy, until he was defeated by the future Henry V. Owain Glyndwr escaped and led guerilla attacks for several years but was never betrayed to the English, disappearing without trace.With Huw Pryce Professor of Welsh History at Bangor UniversityHelen Fulton Professor of Medieval Literature at the University of BristolChris Given-Wilson Emeritus Professor of Medieval History at the University of St AndrewsProducer: Simon Tillotson

Melvyn Bragg and guests discuss the ideas and life of one of the greatest mathematicians of the 20th century, Emmy Noether. Noether’s Theorem is regarded as one of the most important mathematical theorems, influencing the evolution of modern physics. Born in 1882 in Bavaria, Noether studied mathematics at a time when women were generally denied the chance to pursue academic careers and, to get round objections, she spent four years lecturing under a male colleague’s name. In the 1930s she faced further objections to her teaching, as she was Jewish, and she left for the USA when the Nazis came to power. Her innovative ideas were to become widely recognised and she is now considered to be one of the founders of modern algebra.With Colva Roney Dougal Professor of Pure Mathematics at the University of St AndrewsDavid Berman Professor in Theoretical Physics at Queen Mary, University of LondonElizabeth Mansfield Professor of Mathematics at the University of Kent Producer: Simon Tillotson

Melvyn Bragg and guests discuss Samuel Beckett (1906 - 1989), who lived in Paris and wrote his plays and novels in French, not because his French was better than his English, but because it was worse. In works such as Waiting for Godot, Endgame, Molloy and Malone Dies, he wanted to show the limitations of language, what words could not do, together with the absurdity and humour of the human condition. In part he was reacting to the verbal omnipotence of James Joyce, with whom he’d worked in Paris, and in part to his experience in the French Resistance during World War 2, when he used code, writing not to reveal meaning but to conceal it.WithSteven Connor Professor of English at the University of CambridgeLaura Salisbury Professor of Modern Literature at the University of ExeterAnd Mark Nixon Associate Professor in Modern Literature at the University of Reading and co-director of the Beckett International FoundationProducer: Simon Tillotson

Melvyn Bragg and guests discuss why, in 1870, the Vatican Council issued the decree ‘pastor aeternus’ which, among other areas, affirmed papal infallibility. It meant effectively that the Pope could not err in his teachings, an assertion with its roots in the early Church when the bishop of Rome advanced to being the first among equals, then overall head of the Christian Church in the West. The idea that the Pope could not err had been a double-edged sword from the Middle Ages, though; while it apparently conveyed great power, it also meant a Pope was constrained by whatever a predecessor had said. If a later Pope were to contradict an earlier Pope, then one of them must be wrong, and how could that be…if both were infallible?WithTom O’Loughlin Professor of Historical Theology at the University of NottinghamRebecca Rist Professor in Medieval History at the University of ReadingAnd Miles Pattenden Departmental Lecturer in Early Modern History at the University of OxfordProducer: Simon Tillotson and Julia Johnson

Melvyn Bragg and guests discuss the planet Venus which is both the morning star and the evening star, rotates backwards at walking speed and has a day which is longer than its year. It has long been called Earth’s twin, yet the differences are more striking than the similarities. Once imagined covered with steaming jungles and oceans, we now know the surface of Venus is 450 degrees celsius, and the pressure there is 90 times greater than on Earth, enough to crush an astronaut. The more we learn of it, though, the more we learn of our own planet, such as whether Earth could become more like Venus in some ways, over time.

Melvyn Bragg and guests discuss how, from 1834, poor people across England and Wales faced new obstacles when they could no longer feed or clothe themselves, or find shelter. Parliament, in line with the ideas of Jeremy Bentham and Thomas Malthus, feared hand-outs had become so attractive, they stopped people working to support themselves, and encouraged families to have more children than they could afford. To correct this, under the New Poor Laws it became harder to get any relief outside a workhouse, where families would be separated, husbands from wives, parents from children, sisters from brothers. Many found this regime inhumane, while others protested it was too lenient, and it lasted until the twentieth century.The image above was published in 1897 as New Year's Day in the Workhouse.WithEmma Griffin Professor of Modern British History at the University of East AngliaSamantha Shave Lecturer in Social Policy at the University of LincolnAnd Steven King Professor of Economic and Social History at the University of LeicesterProducer: Simon Tillotson

In a programme first broadcast in 2018, Melvyn Bragg and guests discuss one of the jewels of medieval English poetry. It was written c1400 by an unknown poet and then was left hidden in private collections until the C19th when it emerged. It tells the story of a giant green knight who disrupts Christmas at Camelot, daring Gawain to cut off his head with an axe if he can do the same to Gawain the following year. Much to the surprise of Arthur's court, who were kicking the green head around, the decapitated body reaches for his head and rides off, leaving Gawain to face his promise and his apparently inevitable death the following Christmas.The illustration above is ©British Library Board Cotton MS Nero A.x, article 3, ff.94v95With Laura Ashe Professor of English Literature at Worcester College, University of OxfordAd Putter Professor of Medieval English Literature at the University of BristolAnd Simon Armitage Poet and Professor of Poetry at the Universities of Leeds and OxfordProducer: Simon Tillotson

Melvyn Bragg and guests discuss the war in Europe which begain in 1618 and continued on such a scale and with such devastation that its like was not seen for another three hundred years. It pitched Catholics against Protestants, Lutherans against Calvinists and Catholics against Catholics across the Holy Roman Empire, drawing in their neighbours and it lasted for thirty gruelling years, from the Defenestration of Prague to the Peace of Westphalia of 1648. Many more civilians died than soldiers, and famine was so great that even cannibalism was excused. This topic was chosen from several hundred suggested by listeners this autumn.The image above is a detail from a painting of The Battle of White Mountain on 7-8 November 1620, by Pieter Snayers (1592-1667)WithPeter Wilson Chichele Professor of the History of War at the University of OxfordUlinka Rublack Professor of Early Modern European History at the University of Cambridge and Fellow of St John’s CollegeAndToby Osborne Associate Professor in History at Durham UniversityProducer: Simon Tillotson

Melvyn Bragg and guests discuss a foundation story for China as it was reshaped under Mao Zedong. In October 1934, around ninety thousand soldiers of the Red Army broke out of a siege in Jiangxi in the south east of the country, hoping to find a place to regroup and rebuild. They were joined by other armies, and this turned into a very long march to the west and then north, covering thousands of miles of harsh and hostile territory, marshes and mountains, pursued by forces of the ruling Kuomintang for a year. Mao Zedong was among the marchers and emerged at the head of them, and he ensured the officially approved history of the Long March would be an inspiration and education for decades to come.WithRana Mitter Professor of the History and Politics of Modern China and Fellow of St Cross College, University of OxfordSun Shuyun Historian, writer of 'The Long March' and film makerAndJulia Lovell Professor in Modern Chinese History and Literature at Birkbeck, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the philosophy of hope. To the ancient Greeks, hope was closer to self-deception, one of the evils left in Pandora's box or jar, in Hesiod's story. In Christian tradition, hope became one of the theological virtues, the desire for divine union and the expectation of receiving it, an action of the will rather than the intellect. To Kant, 'what may I hope' was one of the three basic questions which human reason asks, while Nietzsche echoed Hesiod, arguing that leaving hope in the box was a deception by the gods, reflecting human inability to face the demands of existence. Yet even those critical of hope, like Camus, conceded that life was nearly impossible without it.WithBeatrice Han-Pile Professor of Philosophy at the University of EssexRobert Stern Professor of Philosophy at the University of SheffieldAndJudith Wolfe Professor of Philosophical Theology at the University of St AndrewsProducer: Simon Tillotson

Melvyn Bragg and guests discuss Horace (65-8BC), who flourished under the Emperor Augustus. He was one of the greatest poets of his age and is one of the most quoted of any age. Carpe diem, nil desperandum, nunc est bibendum – that’s Horace. He was the son of a freedman from southern Italy and, thanks to his talent, achieved high status in Rome despite fighting on the losing side in the civil wars. His Odes are widely thought his most enduring works, yet he also wrote his scurrilous Epodes, some philosophical Epistles and broad Satires. He’s influenced poets ever since, including those such as Wilfred Owen who rejected his line: ‘dulce et decorum est pro patria mori’.With Emily Gowers Professor of Latin Literature at the University of Cambridge and Fellow of St John’s CollegeWilliam Fitzgerald Professor of Latin Language and Literature at King’s College Londonand Ellen O’Gorman Senior Lecturer in Classics at the University of BristolProducer: Simon Tillotson

In a programme first broadcast in November 2018, Melvyn Bragg and guests discuss the Austrian princess Maria Antonia, child bride of the future French King Louis XVI. Their marriage was an attempt to bring about a major change in the balance of power in Europe and to undermine the influence of Prussia and Great Britain, but she had no say in the matter and was the pawn of her mother, the Empress Maria Theresa. She fulfilled her allotted role of supplying an heir, but was sent to the guillotine in 1793 in the French Revolution, a few months after her husband, following years of attacks on her as a woman who, it was said, betrayed the King and as a foreigner who betrayed France to enemy powers. When not doing these wrongs, she was said to be personally bankrupting France. Her death shocked royal families throughout Europe, and she became a powerful symbol of the consequences of the Revolution.

Melvyn Bragg and guests discuss the properties of atoms or molecules with a single unpaired electron, which tend to be more reactive, keen to seize an electron to make it a pair. In the atmosphere, they are linked to reactions such as rusting. Free radicals came to prominence in the 1950s with the discovery that radiation poisoning operates through free radicals, as it splits water molecules and produces a very reactive hydroxyl radical which damages DNA and other molecules in the cell. There is also an argument that free radicals are a byproduct of normal respiration and over time they cause an accumulation of damage that is effectively the process of ageing. For all their negative associations, free radicals play an important role in signalling and are also linked with driving cell division, both cancer and normal cell division, even if they tend to become damaging when there are too many of them.With Nick Lane Professor of Evolutionary Biochemistry at University College LondonAnna Croft Associate Professor at the Department of Chemical and Environmental Engineering at the University of NottinghamAnd Mike Murphy Professor of Mitochondrial Redox Biology at Cambridge UniversityProducer: Simon Tillotson

Melvyn Bragg and guests discuss Bernard Mandeville (1670-1733) and his critique of the economy as he found it in London, where private vices were condemned without acknowledging their public benefit. In his poem The Grumbling Hive (1705), he presented an allegory in which the economy collapsed once knavish bees turned honest. When republished with a commentary, The Fable of the Bees was seen as a scandalous attack on Christian values and Mandeville was recommended for prosecution for his tendency to corrupt all morals. He kept writing, and his ideas went on to influence David Hume and Adam Smith, as well as Keynes and Hayek.With David Wootton Anniversary Professor of History at the University of YorkHelen Paul Lecturer in Economics and Economic History at the University of SouthamptonAnd John Callanan Senior Lecturer in Philosophy at King’s College LondonProducer: Simon Tillotson

In the second of two programmes marking In Our Time's 20th anniversary on 15th October, Melvyn Bragg and guests discuss Shakespeare's versions of history, continuing with the Roman plays. Rome was the setting for Titus Andronicus, Julius Caesar, Coriolanus and parts of Antony and Cleopatra and these plays gave Shakespeare the chance to explore ideas too controversial for English histories. How was Shakespeare reimagining Roman history, and what impact has that had on how we see Rome today?

In the first of two programmes marking In Our Time's 20th anniversary on 15th October, Melvyn Bragg and guests discuss Shakespeare's versions of history, starting with the English Plantagenets. His eight plays from Richard II to Richard III were written out of order, in the Elizabethan era, and have had a significant impact on the way we see those histories today. In the second programme, Melvyn discusses the Roman plays.The image above is of Richard Burton (1925 - 1984) as Henry V in the Shakespeare play of the same name, from 1951WithEmma Smith Professor of Shakespeare Studies at Hertford College, University of OxfordGordon McMullan Professor of English at King’s College London and Director of the London Shakespeare CentreAnd Katherine Lewis Senior Lecturer in Medieval History at the University of HuddersfieldProducer: Simon Tillotson

Melvyn Bragg and guests discuss the works of Wharton (1862-1937) such as The Age of Innocence for which she won the Pulitzer Prize and was the first woman to do so, The House of Mirth, and The Custom of the Country. Her novels explore the world of privileged New Yorkers in the Gilded Age of the late C19th, of which she was part, drawing on her own experiences and written from the perspective of the new century, either side of WW1 . Among her themes, she examined the choices available to women and the extent to which they could ever really be free, even if rich.

Melvyn Bragg and guests discuss the ideas and life of the German theologian, born in Breslau/Wroclaw in 1906 and killed in the Flossenbürg concentration camp on 9th April 1945. Bonhoeffer developed ideas about the role of the Church in the secular world, in particular Germany after the Nazis took power in 1933 and demanded the Churches' support. He strongly opposed anti-Semitism and, with a role in the Military Intelligence Department, took part in the resistance, plotting to kill Hitler and meeting with contacts in the Allies. Bonhoeffer's ideas on Christian ethics and the relationship between Christianity and humanism spread more widely from the 1960s with the discovery of unpublished works, including those written in prison as he awaited execution.With Stephen Plant Dean and Runcie Fellow at Trinity Hall at the University of CambridgeEleanor McLaughlin Lecturer in Theology and Ethics at the University of Winchester and Lecturer in Ethics at Regent’s Park College at the University of OxfordAnd Tom Greggs Marischal Chair of Divinity at the University of AberdeenProducer: Simon Tillotson

Melvyn Bragg and guests discuss the history of real and imagined machines that appear to be living, and the questions they raise about life and creation. Even in myth they are made by humans, not born. The classical Greeks built some and designed others, but the knowledge of how to make automata and the principles behind them was lost in the Latin Christian West, remaining in the Greek-speaking and Arabic-speaking world. Western travellers to those regions struggled to explain what they saw, attributing magical powers. The advance of clockwork raised further questions about what was distinctly human, prompting Hobbes to argue that humans were sophisticated machines, an argument explored in the Enlightenment and beyond.The image above is Jacques de Vaucanson's mechanical duck (1739), which picked up grain, digested and expelled it.

Melvyn Bragg and guests discuss the great epic poem attributed to Homer, telling the story of an intense episode in the Trojan War. It is framed by the wrath of the Greek hero Achilles, insulted by his leader Agamemnon and withdrawing from the battle that continued to rage, only returning when his close friend Patroclus is killed by the Trojan hero Hector. Achilles turns his anger from Agamemnon to Hector and the fated destruction of Troy comes ever closer.

Melvyn Bragg and guests discuss the ideas of William Morris, known in his lifetime for his poetry and then his contribution to the Arts and Crafts movement, and increasingly for his political activism. He felt the world had given in to drudgery and ugliness and he found inspiration in the time before industrialisation, in the medieval life which was about fellowship and association and ways of working which resisted the division of labour and allowed the worker to exercise his or her imagination. Seeing a disconnection between art and society, his solution was revolution which in his view was the only way to reset their relationship.The image above is from the Strawberry Thief wallpaper design by William Morris.With Ingrid Hanson Lecturer in 18th and 19th Century Literature at the University of ManchesterMarcus Waithe University Senior Lecturer in English Literature at the University of Cambridge and Fellow of Magdalene CollegeAndJane Thomas Professor of Victorian and Early 20th Century Literature at the University of HullProducer: Simon Tillotson.

Melvyn and guests discuss the 1846-48 conflict after which the United States of Mexico lost half its territory to the United States of America. The US gained land covered by the states of Texas, Utah, California, New Mexico, Nevada, Arizona and part of Colorado. The outcome had a profound impact on Native Americans and led to civil war in defeated Mexico. It also raised the question of whether slavery would be legal in this acquired territory - something that would only be resolved in the US Civil War, which this victory hastened.With Frank Cogliano Professor of American History at the University of EdinburghJacqueline Fear-Segal Professor of American and Indigenous Histories at the University of East AngliaAndThomas Rath Lecturer in Latin American History at University College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss how some bats, dolphins and other animals emit sounds at high frequencies to explore their environments, rather than sight. This was such an unlikely possibility, to natural historians from C18th onwards, that discoveries were met with disbelief even into the C20th; it was assumed that bats found their way in the dark by touch. Not all bats use echolocation, but those that do have a range of frequencies for different purposes and techniques for preventing themselves becoming deafened by their own sounds. Some prey have evolved ways of detecting when bats are emitting high frequencies in their direction, and some fish have adapted to detect the sounds dolphins use to find them.

Melvyn Bragg and guests discuss the ideas of Charles-Louis de Secondat, Baron de La Brède et de Montesquieu (1689-1755) whose works on liberty, monarchism, despotism, republicanism and the separation of powers were devoured by intellectuals across Europe and New England in the eighteenth century, transforming political philosophy and influencing the American Constitution. He argued that an individual's liberty needed protection from the arm of power, checking that by another power; where judicial, executive and legislative power were concentrated in the hands of one figure, there could be no personal liberty.

Melvyn Bragg and guests discuss the role of the great 'City of the Persians' founded by Darius I as the ceremonial capital of the Achaemenid Empire that stretched from the Indus Valley to Egypt and the coast of the Black Sea. It was known as the richest city under the sun and was a centre at which the Empire's subject peoples paid tribute to a succession of Achaemenid leaders, until the arrival of Alexander III of Macedon who destroyed it by fire supposedly in revenge for the burning of the Acropolis in Athens.The image above is a detail from a relief at the Apadana, the huge audience hall, and shows a lion attacking a bull.With Lloyd Llewellyn-Jones Professor of Ancient History at Cardiff UniversityVesta Sarkhosh Curtis Curator of Middle Eastern Coins at the British MuseumAndLindsay Allen Lecturer in Greek and Near Eastern History at King's College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the great Norwegian playwright and poet, best known for his middle class tragedies such as The Wild Duck, Hedda Gabler, A Doll's House and An Enemy of the People. These are set in a world where the middle class is dominant and explore the qualities of that life, its weaknesses and boundaries and the ways in which it takes away freedoms. It is the women who fare the worst in this society, something Ibsen explored in A Doll's House among others, a play that created a sensation with audiences shocked to watch a woman break free of her bourgeois family life to find her destiny. He explored dark secrets such as incest and, in Ghosts, hereditary syphilis, which attracted the censors. He gave actresses parts they had rarely had before, and audiences plays that, after Shakespeare, became the most performed in the world.With Tore Rem Professor of English Literature at the University of OsloKirsten Shepherd-Barr Professor of English and Theatre Studies and Tutorial Fellow, St Catherine's College at the University of OxfordAnd Dinah Birch Professor of English Literature and Pro-Vice Chancellor for Cultural Engagement at the University of LiverpoolProducer: Simon Tillotson.

Melvyn Bragg and guests discuss one of the most remarkable queens of the Middle Ages who took control when her husband, Henry VI, was incapable. Margaret of Anjou (1430-1482) wanted Henry to stay in power for the sake of their son, the heir to the throne, and her refusal to back down was seen by her enemies as a cause of the great dynastic struggle of the Wars of the Roses. The image above is from the Talbot Shrewsbury Book, showing John Talbot, 1st Earl of Shrewsbury, presenting Margaret with that book on her betrothal to HenryWithKatherine Lewis Senior Lecturer in Medieval History at the University of HuddersfieldJames Ross Reader in Late Medieval History at the University of WinchesterAnd Joanna Laynesmith Visiting Research Fellow at the University of ReadingProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the 1861 declaration by Tsar Alexander II that serfs were now legally free of their landlords. Until then, over a third of Russians were tied to the land on which they lived and worked and in practice there was little to distinguish their condition from slavery. Russia had lost the Crimean War in 1855 and there had been hundreds of uprisings, prompting the Tsar to tell the nobles, "The existing condition of owning souls cannot remain unchanged. It is better to begin to destroy serfdom from above than to wait until that time when it begins to destroy itself from below." Reform was constrained by the Tsar's wish to keep the nobles on side and, for the serfs, tied by debt and law to the little land they were then allotted, the benefits were hard to see.

Melvyn Bragg and guests discuss the eleven stories of Celtic mythology and Arthurian romance known as The Mabinogion, most of which were told and retold for generations before being written down in C14th. Among them are stories of Pwyll and Rhiannon and their son Pryderi, of Culhwch and Olwen, of the dream of the Emperor Macsen, of Lludd and Llefelys, of magic and giants and imagined history. With common themes but no single author, they project an image of the Island of Britain before the Anglo-Saxons and Normans and before Edward I's conquest of Wales. They came to new prominence, worldwide, from C19th with the translation into English by Lady Charlotte Guest aided by William Owen Pughe.The image above is of Cynon ap Clydno approaching the Castle of Maidens from the tale of Owain, or the Lady of the FountainWith Sioned Davies Professor in the School of Welsh at Cardiff UniversityHelen Fulton Professor of Medieval Literature at the University of BristolAndJuliette Wood Associate Lecturer in the School of Welsh at Cardiff UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Berber people who grew to dominate the western Maghreb, founded Marrakesh and took control of Al-Andalus. They were desert people, wearing veils over their faces to keep out the sand, and they wanted a simpler form of Islam. They called themselves the Murabitun, the people who gathered together to fight the holy war, and they were tough fighters; the Spanish knight El Cid fought them and lost, and the legend that built around him said the Almoravids were terrible and had to be resisted. They kept back the Christians of northern Spain, so helping extend Muslim rule in the Iberian Peninsula, before they themselves were destroyed and replaced by their rivals, the Almohads, from the Atlas Mountains.The image above shows the interior of the cupola, Almoravid Koubba, Marrakesh (C11th)With Amira K Bennison Professor in the History and Culture of the Maghreb at the University of CambridgeNicola Clarke Lecturer in the History of the Islamic World at Newcastle UniversityAnd Hugh Kennedy Professor of Arabic at SOAS, University of LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the discovery and growing understanding of the Proton, formed from three quarks close to the Big Bang and found in the nuclei of all elements. The positive charges they emit means they attract the fundamental particles of negatively charged electrons, an attraction that leads to the creation of atoms which in turn leads to chemistry, biology and life itself. The Sun (in common with other stars) is a fusion engine that turn protons by a series of processes into helium, emitting energy in the process, with about half of the Sun's protons captured so far. Hydrogen atoms, stripped of electrons, are single protons which can be accelerated to smash other nuclei and have applications in proton therapy. Many questions remain, such as why are electrical charges for protons and electrons so perfectly balanced?WithFrank Close Professor Emeritus of Physics at the University of OxfordHelen Heath Reader in Physics at the University of BristolAndSimon Jolly Lecturer in High Energy Physics at University College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss what Virginia Woolf called 'one of the few English novels written for grown-up people'. It was written by George Eliot, the pen name of Mary Anne Evans (1819-80), published in 8 parts in 1871-72, and was originally two separate stories which became woven together. One, 'Middlemarch', focused on a doctor, Tertius Lydgate and the other, 'Miss Brooke', on Dorothea Brooke who became the central figure in the finished work. The events are set in a small town in the Midlands, surrounded by farmland, leading up to the Reform Act 1832, and the novel explores the potential to change in matters of religion, social status, marriage and politics, and is particularly concerned with the opportunities available to women to lead fulfilling lives.

In a programme first broadcast on April 12th 2018, Melvyn Bragg and guests discuss the contribution of George Stephenson (1781-1848) and his son Robert (1803-59) to the development of the railways in C19th. George became known as The Father of Railways and yet arguably Robert's contribution was even greater, with his engineering work going far beyond their collaboration. Robert is credited with the main role in the design of their locomotives. George had worked on stationary colliery steam engines and, with Robert, developed the moving steam engine Locomotion No1 for the Stockton and Darlington Railway in 1825. They produced the Rocket for the Rainhill Trials on the Liverpool and Manchester Railway in 1829. From there, the success of their designs and engineering led to the expansion of railways across Britain and around the world. with Dr Michael Bailey Railway historian and editor of the most recent biography of Robert StephensonJulia Elton Past President of the Newcomen Society for the History of Engineering and TechnologyandColin Divall Professor Emeritus of Railway Studies at the University of YorkProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the role of slavery in the Roman world, from its early conquests to the fall of the Western Empire. The system became so entrenched that no-one appeared to question it, following Aristotle's view that slavery was a natural state. Whole populations could be marched into slavery after military conquests, and the freedom that Roman citizens prized for themselves, even in poverty, was partly defined by how it contrasted with enslavement. Slaves could be killed or tortured with impunity, yet they could be given great responsibility and, once freed, use their contacts to earn fortunes. The relationship between slave and master informed early Christian ideas of how the faithful related to God, informing debate for centuries.WithNeville Morley Professor of Classics and Ancient History at the University of ExeterUlrike Roth Senior Lecturer in Ancient History at the University of EdinburghAndMyles Lavan Senior lecturer in Ancient History at the University of St AndrewsProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Alexis de Tocqueville (1805-1859) and his examination of the American democratic system. He wrote De La Démocratie en Amérique in two parts, published in 1835 and 1840, when France was ruled by the July Monarchy of Louis-Philippe. Tocqueville was interested in how aspects of American democracy, in the age of President Andrew Jackson, could be applied to Europe as it moved away from rule by monarchs and aristocrats. His work has been revisited by politicians ever since, particularly in America, with its analysis of the strengths and weaknesses of direct democracy and its warnings of mediocrity and the tyranny of the majority.WithRobert Gildea Professor of Modern History at the University of OxfordSusan-Mary Grant Professor of American History at Newcastle Universityand Jeremy Jennings Professor of Political Theory and Head of the School of Politics & Economics at King's College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss St Augustine of Hippo's account of his conversion to Christianity and his life up to that point. Written c397AD, it has many elements of autobiography with his scrutiny of his earlier life, his long relationship with a concubine, his theft of pears as a child, his work as an orator and his embrace of other philosophies and Manichaeism. Significantly for the development of Christianity, he explores the idea of original sin in the context of his own experience. The work is often seen as an argument for his Roman Catholicism, a less powerful force where he was living in North Africa where another form of Christianity was dominant, Donatism. While Augustine retells many episodes from his own life, the greater strength of his Confessions has come to be seen as his examination of his own emotional development, and the growth of his soul.WithKate Cooper Professor of History at the University of London and Head of History at Royal HollowayMorwenna Ludlow Professor of Christian History and Theology at the University of Exeterand Martin Palmer Visiting Professor in Religion, History and Nature at the University of WinchesterProducer: Simon Tillotson.

Melvyn Bragg and guests discuss how and why Highlanders and Islanders were cleared from their homes in waves in C18th and C19th, following the break up of the Clans after the Battle of Culloden. Initially, landlords tried to keep people on their estates for money-making schemes, but the end of the Napoleonic Wars brought convulsive changes. Some of the evictions were notorious, with the sudden and fatal burning of townships, to make way for sheep and deer farming. For many, migration brought a new start elsewhere in Britain or in the British colonies, while for some it meant death from disease while in transit. After more than a century of upheaval, the Clearances left an indelible mark on the people and landscape of the Highlands and Western Isles.The image above is a detail from a print of 'Lochaber No More' by John Watson Nicol 1856-1926With Sir Tom Devine Professor Emeritus of Scottish History at the University of EdinburghMarjory Harper Professor of History at the University of Aberdeen and Visiting Professor at the University of the Highlands and IslandsAndMurray Pittock Bradley Professor of English Literature and Pro Vice Principal at the University of GlasgowProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the ideas attributed to Sun Tzu (544-496BC, according to tradition), a legendary figure from the beginning of the Iron Age in China, around the time of Confucius. He may have been the historical figure Sun Wu, a military adviser at the court of King Helu of Wu (who reigned between about 514 and 496 BC), one of the kings in power in the Warring States period of Chinese history (6th - 5th century BC). Sun Tzu was credited as the author of The Art of War, a work on military strategy that soon became influential in China and then Japan both for its guidance on conducting and avoiding war and for its approach to strategy generally. After The Art of War was translated into European languages in C18th, its influence spread to military academies around the world.The image above is of a terracotta warrior from the tomb of Qin Shi Huang, the first Emperor, who unified China after the Warring States period.With Hilde De Weerdt Professor of Chinese History at Leiden UniversityTim Barrett Professor Emeritus of East Asian History at SOAS, University of LondonAndImre Galambos Reader in Chinese Studies at the University of CambridgeProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the pioneering scientist Rosalind Franklin (1920 - 1958). During her distinguished career, Franklin carried out ground-breaking research into coal and viruses but she is perhaps best remembered for her investigations in the field of DNA. In 1952 her research generated a famous image that became known as Photograph 51. When the Cambridge scientists Francis Crick and James Watson saw this image, it enabled them the following year to work out that DNA has a double-helix structure, one of the most important discoveries of modern science. Watson, Crick and Franklin's colleague Maurice Wilkins received a Nobel Prize in 1962 for this achievement but Franklin did not and today many people believe that Franklin has not received enough recognition for her work.

Melvyn Bragg and guests discuss fungi. These organisms are not plants or animals but a kingdom of their own. Millions of species of fungi live on the Earth and they play a crucial role in ecosystems, enabling plants to obtain nutrients and causing material to decay. Without fungi, life as we know it simply would not exist. They are also a significant part of our daily life, making possible the production of bread, wine and certain antibiotics. Although fungi brought about the colonisation of the planet by plants about 450 million years ago, some species can kill humans and devastate trees.

In a programme first broadcast in 2018, Melvyn Bragg and guests discuss the life and ideas of Frederick Douglass, who was born into slavery in Maryland in 1818 and, once he had escaped, became one of that century's most prominent abolitionists. He was such a good orator, his opponents doubted his story, but he told it in grim detail in 1845 in his book 'Narrative of the Life of Frederick Douglass, an American Slave.' He went on to address huge audiences in Great Britain and Ireland and there some of his supporters paid off his owner, so Douglass could be free in law and not fear recapture. After the Civil War and the abolition of slavery, he campaigned for equal rights for African-Americans, arguing against those such as Lincoln who had wanted freed slaves to leave America and found a colony elsewhere. "We were born here," he said, "and here we will remain."WithCeleste-Marie Bernier Professor of Black Studies in the English Department at the University of EdinburghKaren Salt Assistant Professor in Transnational American Studies at the University of NottinghamAndNicholas Guyatt Reader in North American History at the University of CambridgeProducer: Simon Tillotson.

The octopus, the squid, the nautilus and the cuttlefish are some of the most extraordinary creatures on this planet, intelligent and yet apparently unlike other life forms. They are cephalopods and are part of the mollusc family like snails and clams, and they have some characteristics in common with those. What sets them apart is the way members of their group can change colour, camouflage themselves, recognise people, solve problems, squirt ink, power themselves with jet propulsion and survive both on land, briefly, and in the deepest, coldest oceans. And, without bones or shells, they grow so rapidly they can outstrip their rivals when habitats change, making them the great survivors and adaptors of the animal world.WithLouise Allcock Lecturer in Zoology at the National University of Ireland, GalwayPaul Rodhouse Emeritus Fellow of the British Antarctic SurveyandJonathan Ablett Senior Curator of Molluscs at the Natural History MuseumProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the ideas developed by Marcus Tullius Cicero (106-43BC) to support and reinvigorate the Roman Republic when, as it transpired, it was in its final years, threatened by civil wars, the rule of Julius Caesar and the triumvirates that followed. As Consul he had suppressed a revolt by Catiline, putting the conspirators to death summarily as he believed the Republic was in danger and that this danger trumped the right to a fair trial, a decision that rebounded on him. While in exile he began works on duty, laws, the orator and the republic. Although left out of the conspiracy to kill Caesar, he later defended that murder in the interests of the Republic, only to be murdered himself soon after.With Melissa Lane The Class of 1943 Professor of Politics at Princeton University and 2018 Carlyle Lecturer at the University of OxfordCatherine Steel Professor of Classics at the University of GlasgowAndValentina Arena Reader in Roman History at University College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the work, ideas and life of the Russian poet whose work was celebrated in C20th both for its quality and for what it represented, written under censorship in the Stalin years. Her best known poem, Requiem, was written after her son was imprisoned partly as a threat to her and, to avoid punishment for creating it, she passed it on to her supporters to be memorised, line by line, rather than written down. She was a problem for the authorities and became significant internationally, as her work came to symbolise resistance to political tyranny and the preservation of pre-Revolutionary liberal values in the Soviet era.The image above is based on 'Portrait of Anna Akhmatova' by N.I.

Melvyn Bragg and guests discuss the event of which Voltaire, two hundred years later, said 'nothing was more well known'. In 1565, Suleiman the Magnificent, the Ottoman leader, sent a great fleet west to lay siege to Malta and capture it for his empire. Victory would mean control of trade across the Mediterranean and a base for attacks on Spain, Sicily and southern Italy, even Rome. It would also mean elimination of Malta's defenders, the Knights Hospitaller, driven by the Ottomans from their base in Rhodes in 1522 and whose raids on his shipping had long been a thorn in his side. News of the Great Siege of Malta spread fear throughout Europe, though that turned to elation when, after four months of horrific fighting, the Ottomans withdrew, undermined by infighting between their leaders and the death of the highly-valued admiral, Dragut. The Knights Hospitaller had shown that Suleiman's forces could be contained, and their own order was reinvigorated. The image above is the Death of Dragut at the Siege of Malta (1867), after a painting by Giuseppe Cali. Dragut (1485 – 1565) was an Ottoman Admiral and privateer, known as The Drawn Sword of Islam and as one of the finest generals of the time.With Helen Nicholson Professor of Medieval History at Cardiff UniversityDiarmaid MacCulloch Professor of the History of the Church at the University of OxfordandKate Fleet Director of the Skilliter Centre for Ottoman Studies and Fellow of Newnham College, CambridgeProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Shakespeare's best known, most quoted and longest play, written c1599 - 1602 and rewritten throughout his lifetime. It is the story of Hamlet, Prince of Denmark, encouraged by his father's ghost to take revenge on his uncle who murdered him, and is set at the court of Elsinore. In soliloquies, the Prince reveals his inner self to the audience while concealing his thoughts from all at the Danish court, who presume him insane. Shakespeare gives him lines such as 'to be or not to be,' 'alas, poor Yorick,' and 'frailty thy name is woman', which are known even to those who have never seen or read the play. And Hamlet has become the defining role for actors, men and women, who want to show their mastery of Shakespeare's work. The image above is from the 1964 film adaptation, directed by Grigori Kozintsev, with Innokenty Smoktunovsky as Hamlet.WithSir Jonathan Bate Provost of Worcester College, University of OxfordCarol Rutter Professor of Shakespeare and Performance Studies at the University of WarwickAndSonia Massai Professor of Shakespeare Studies at King's College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss one of the great composers, who was born into a family of musicians in Bonn. His grandfather was an eminent musician and also called Ludwig van Beethoven. His father, who was not as talented as Beethoven's grandfather, drank heavily and died when Beethoven was still young. It was his move to Vienna that allowed him to flourish, with the support at first of aristocratic patrons, when that city was the hub of European music. He is credited with developing the symphony further than any who preceded him, with elevating instrumental above choral music and with transforming music to the highest form of art. He composed his celebrated works while, from his late twenties onwards, becoming increasingly deaf.(Before the live broadcast, BBC Radio 3's Breakfast programme played selections from Beethoven, with Essential Classics playing more, immediately after, on the same network.)With Laura Tunbridge Professor of Music and Henfrey Fellow, St Catherine's College, University of OxfordJohn Deathridge Emeritus King Edward Professor of Music at King's College LondonAndErica Buurman Senior Lecturer in Music, Canterbury Christchurch UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the man who was Henry II's Chancellor and then Archbishop of Canterbury and who was murdered by knights in Canterbury Cathedral (depicted by Matthew Paris, above). Henry believed that Becket owed him loyalty as he had raised him to the highest offices, and that he should agree to Henry's courts having jurisdiction over 'criminous clerics'. They fell out when Becket agreed to this jurisdiction verbally but would not put his seal on the agreement, the Constitutions of Clarendon. The rift deepened when Henry's heir was crowned without Becket, who excommunicated the bishops who took part. Becket's tomb became one of the main destinations for pilgrims for the next 400 years, including those in Chaucer's Canterbury Tales where he was the 'blisful martir'.

Melvyn Bragg and guests discuss Herman Melville's (1819-1891) epic novel, published in London in 1851, the story of Captain Ahab's pursuit of a great white sperm whale that had bitten off his leg. He risks his own life and that of his crew on the Pequod, single-mindedly seeking his revenge, his story narrated by Ishmael who was taking part in a whaling expedition for the first time. This is one of the c1000 ideas which listeners sent in this autumn for our fourth Listener Week, following Kafka's The Trial in 2014, Captain Cook in 2015 and Garibaldi and the Risorgimento in 2016.With Bridget Bennett Professor of American Literature and Culture at the University of LeedsKatie McGettigan Lecturer in American Literature at Royal Holloway, University of LondonAndGraham Thompson Associate Professor of American Studies at the University of NottinghamProducer: Simon Tillotson.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss Gauss (1777-1855), widely viewed as one of the greatest mathematicians of all time. He was a child prodigy, correcting his father's accounts before he was 3, dumbfounding his teachers with the speed of his mental arithmetic, and gaining a wealthy patron who supported his education. He wrote on number theory when he was 21, with his Disquisitiones Arithmeticae, which has influenced developments since. Among his achievements, he was the first to work out how to make a 17-sided polygon, he predicted the orbit of the minor planet Ceres, rediscovering it, he found a way of sending signals along a wire, using electromagnetism, the first electromagnetic telegraph, and he advanced the understanding of parallel lines on curved surfaces.

Melvyn Bragg and guests discuss the myths and history of the ancient Greek city of Thebes and its depiction in Athenian drama. In myths it was said to be home to Heracles, Dionysus, Oedipus and Cadmus among others and, in history, was infamous for supporting Xerxes in the Persian War. Its prominence led to a struggle with the rising force of Macedon in which the Thebans were defeated at Chaironea in 338 BC, one of the most important battles in ancient history. The position of Thebes in Greek culture was enormously powerful.

Melvyn Bragg and guests discuss the life and impact of Germaine de Staël (1766-1817) who Byron praised as Europe's greatest living writer, and was at the heart of intellectual and literary life in the France of revolution and of Napoleon. As well as attracting and inspiring others in her salon, she wrote novels, plays. literary criticism, political essays, and poems and developed the ideas behind Romanticism. She achieved this while regularly exiled from the Paris in which she was born, having fallen out with Napoleon who she opposed, becoming a towering figure in the history of European ideas.With Catriona Seth, Marshal Foch Professor of French Literature at the University of OxfordAlison Finch, Professor Emerita of French Literature at the University of Cambridgeand Katherine Astbury, Associate Professor and Reader in French Studies at the University of Warwick.Producer: Simon Tillotson.

Melvyn Bragg and guests discuss The Picts and, to mark our twentieth season, that discussion takes place in front of a student audience at the University of Glasgow, many of them studying this topic. According to Bede writing c731AD, the Picts, with the English, Britons, Scots and Latins, formed one of the five nations of Britain, 'an island in the ocean formerly called Albion'. The Picts is now a label given to the people who lived in Scotland north of the Forth-Clyde line from about 300 AD to 900 AD, from the time of the Romans to the time of the Vikings. They left intricately carved stones, such as the one above with a bull motif, from Burghead, Moray, Scotland, but there are relatively few other traces. Who were they, and what happened to them? And what has been learned in the last twenty years, through archaeology?

Melvyn Bragg and guests discuss the context and impact of Pablo Picasso's iconic work, created soon after the bombing on 26th April 1937 that obliterated much of the Basque town of Guernica, and its people. The attack was carried out by warplanes of the German Condor Legion, joined by the Italian air force, on behalf of Franco's Nationalists. At first the Nationalists denied responsibility, blaming their opponents for creating the destruction themselves for propaganda purposes, but the accounts of journalists such as George Steer, and the prominence of Picasso's work, kept the events of that day under close scrutiny. Picasso's painting has gone on to become a symbol warning against the devastation of war.With Mary Vincent Professor of Modern European History at the University of SheffieldGijs van Hensbergen Historian of Spanish Art and Fellow of the LSE Cañada Blanch Centre for Contemporary Spanish Studies andDacia Viejo Rose Lecturer in Heritage in the Department of Archaeology at the University of Cambridge Fellow of Selwyn CollegeProducer: Simon Tillotson.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the development of theories about dinosaur feathers, following discoveries of fossils which show evidence of feathers. All dinosaurs were originally thought to be related to lizards - the word 'dinosaur' was created from the Greek for 'terrible lizard' - but that now appears false. In the last century, discoveries of fossils with feathers established that at least some dinosaurs were feathered and that some of those survived the great extinctions and evolved into the birds we see today. There are still many outstanding areas for study, such as what sorts of feathers they were, where on the body they were found, what their purpose was and which dinosaurs had them.

Melvyn Bragg and guests discuss the conference convened by the victorious powers of the Napoleonic Wars and the earlier French Revolutionary Wars, which had devastated so much of Europe over the last 25 years. The powers aimed to create a long lasting peace, partly by redrawing the map to restore old boundaries and partly by balancing the powers so that none would risk war again. It has since been seen as a very conservative outcome, reasserting the old monarchical and imperial orders over the growth of liberalism and national independence movements, and yet also largely successful in its goal of preventing war in Europe on such a scale for another 100 years. Delegates to Vienna were entertained at night with lavish balls, and the image above is from a French cartoon showing Russia, Prussia, and Austria dancing to the bidding of Castlereagh, the British delegate.With Kathleen Burk Professor Emerita of Modern and Contemporary History at University College LondonTim Blanning Emeritus Professor of Modern European History at the University of CambridgeandJohn Bew Professor in History and Foreign Policy at the War Studies Department at King's College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Aphra Behn (1640-1689), who made her name and her living as a playwright, poet and writer of fiction under the Restoration. Virginia Woolf wrote of her: ' All women together, ought to let flowers fall upon the grave of Aphra Behn... for it was she who earned them the right to speak their minds'. Behn may well have spent some of her early life in Surinam, the setting for her novel Oroonoko, and there are records of her working in the Netherlands as a spy for Charles II. She was loyal to the Stuart kings, and refused to write a poem on the coronation of William of Orange. She was regarded as an important writer in her lifetime and inspired others to write, but fell out of favour for two centuries after her death when her work was seen as too bawdy, the product of a disreputable age. The image above is from the Yale Center for British Art and is titled 'Aphra Behn, by Sir Peter Lely, 1618-1680' With Janet Todd Former President of Lucy Cavendish College, Cambridge UniversityRos Ballaster Professor of 18th Century Literature at Mansfield College, University of Oxfordand Claire Bowditch Post-doctoral Research Associate in English and Drama at Loughborough UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the life, reputation and impact of Constantine I, known as Constantine the Great (c280s -337AD). Born in modern day Serbia and proclaimed Emperor by his army in York in 306AD, Constantine became the first Roman Emperor to profess Christianity. He legalised Christianity and its followers achieved privileges that became lost to traditional religions, leading to the steady Christianisation of the Empire. He built a new palace in Byzantium, renaming it Constantinople, as part of the decentralisation of the Empire, an Eastern shift that saw Roman power endure another thousand years there, long after the collapse of the empire in the West.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss Emily Bronte (1818-1848) and her only novel, published in 1847 under the name 'Ellis Bell' just a year before her death. It is the story of Heathcliff, a foundling from Liverpool brought up in the Earnshaw family at the remote Wuthering Heights, high on the moors, who becomes close to the young Cathy Earnshaw but hears her say she can never marry him. He disappears and she marries his rival, Edgar Linton, of Thrushcross Grange even though she feels inextricably linked with Heathcliff, exclaiming to her maid 'I am Heathcliff!' On his return, Heathcliff steadily works through his revenge on all who he believes wronged him, and their relations. When Cathy dies, Heathcliff longs to be united with her in the grave. The raw passions and cruelty of the story unsettled Emily's sister Charlotte Bronte, whose novel Jane Eyre had been published shortly before, and who took pains to explain its roughness, jealousy and violence when introducing it to early readers. Over time, with its energy, imagination and scope, Wuthering Heights became celebrated as one of the great novels in English.The image above is of Laurence Olivier as Heathcliff and Merle Oberon as Cathy on the set of the Samuel Goldwyn Company movie 'Wuthering Heights', circa 1939.WithKaren O'Brien Professor of English Literature at the University of OxfordJohn Bowen Professor of Nineteenth Century Literature at the University of Yorkand Alexandra Lewis Lecturer in English Literature at the University of AberdeenProducer: Simon Tillotson.

Melvyn Bragg and guests discuss how, in the Enlightenment, Immanuel Kant (1724-1804) sought to define the difference between right and wrong by applying reason, looking at the intention behind actions rather than at consequences. He was inspired to find moral laws by natural philosophers such as Newton and Leibniz, who had used reason rather than emotion to analyse the world around them and had identified laws of nature. Kant argued that when someone was doing the right thing, that person was doing what was the universal law for everyone, a formulation that has been influential on moral philosophy ever since and is known as the Categorical Imperative. Arguably even more influential was one of his reformulations, echoed in The Universal Declaration of Human Rights, in which he asserted that humanity has a value of an entirely different kind from that placed on commodities. Kant argued that simply existing as a human being was valuable in itself, so that every human owed moral responsibilities to other humans and was owed responsibilities in turn.With Alison Hills Professor of Philosophy at St John's College, OxfordDavid Oderberg Professor of Philosophy at the University of ReadingandJohn Callanan Senior Lecturer in Philosophy at King's College, LondonProducer: Simon Tillotson.

Melvyn Bragg and his guests discuss the Central Asian polymath al-Biruni and his eleventh-century book the India.Born in around 973 in the central Asian region of Chorasmia, al-Biruni became an itinerant scholar of immense learning, a master of mathematics, medicine, astronomy and many languages. He corresponded with the age's greatest scientist, Avicenna, and made significant contributions to many fields of knowledge.In 1017 al-Biruni became a member of the court of the ruler Mahmud of Ghazna. Over the course of the next thirteen years he wrote the India, a comprehensive account of Hindu culture which was the first book about India by a Muslim scholar. It contains detailed information about Hindu religion, science and everyday life which have caused some to call it the first work of anthropology.With:James MontgomeryProfessor of Classical Arabic at the University of CambridgeHugh KennedyProfessor of Arabic in the School of Oriental and African Studies at the University of LondonAmira BennisonSenior Lecturer in Middle Eastern and Islamic Studies at the University of CambridgeProducer: Thomas Morris.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss why some birds migrate and others do not, how they select their destinations and how they navigate the great distances, often over oceans. For millennia, humans set their calendars to birds' annual arrivals, and speculated about what happened when they departed, perhaps moving deep under water, or turning into fish or shellfish, or hibernating while clinging to trees upside down. Ideas about migration developed in C19th when, in Germany, a stork was noticed with an African spear in its neck, indicating where it had been over the winter and how far it had flown. Today there are many ideas about how birds use their senses of sight and smell, and magnetic fields, to find their way, and about why and how birds choose their destinations and many questions. Why do some scatter and some flock together, how much is instinctive and how much is learned, and how far do the benefits the migrating birds gain outweigh the risks they face?With Barbara Helm Reader at the Institute of Biodiversity, Animal Health and Comparative Medicine at the University of GlasgowTim Guilford Professor of Animal Behaviour and Tutorial Fellow of Zoology at Merton College, Oxfordand Richard Holland Senior Lecturer in Animal Cognition at Bangor UniversityProducer: Simon Tillotson.

Is it always better to be just than unjust? That is the central question of Plato's Republic, discussed here by Melvyn Bragg and guests. Writing in c380BC, Plato applied this question both to the individual and the city-state, considering earlier and current forms of government in Athens and potential forms, in which the ideal city might be ruled by philosophers. The Republic is arguably Plato's best known and greatest work, a dialogue between Socrates and his companions, featuring the allegory of the cave and ideas about immortality of the soul, the value of poetry to society, and democracy's vulnerability to a clever demagogue seeking tyranny.With Angie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldMM McCabe Professor of Ancient Philosophy Emerita at King's College LondonandJames Warren Fellow of Corpus Christi College and a Reader in Ancient Philosophy at the University of Cambridge Producer: Simon Tillotson.

Melvyn Bragg and guests discuss Alexander Pushkin's verse novel, the story of Eugene Onegin, widely regarded as his masterpiece. Pushkin (pictured above) began this in 1823 and worked on it over the next ten years, while moving around Russia, developing the central character of a figure all too typical of his age, the so-called superfluous man. Onegin is cynical, disillusioned and detached, his best friend Lensky is a romantic poet and Tatyana, whose love for Onegin is not returned until too late, is described as a poetic ideal of a Russian woman, and they are shown in the context of the Russian landscape and society that has shaped them. Onegin draws all three into tragic situations which, if he had been willing and able to act, he could have prevented, and so becomes the one responsible for the misery of himself and others as well as the death of his friend.With Andrew Kahn Professor of Russian Literature at the University of Oxford and Fellow of St Edmund HallEmily Finer Lecturer in Russian and Comparative Literature at the University of St Andrewsand Simon Dixon The Sir Bernard Pares Professor of Russian History at University College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss what, in C19th America's Gilded Age, was one of the most significant protest movements since the Civil War with repercussions well into C20th. Farmers in the South and Midwest felt ignored by the urban and industrial elites who were thriving as the farmers suffered droughts and low prices. The farmers were politically and physically isolated. As one man wrote on his abandoned farm, 'two hundred and fifty miles to the nearest post office, one hundred miles to wood, twenty miles to water, six inches to Hell'. They formed the Populist or People's Party to fight their cause, put up candidates for President, won several states and influenced policies. In the South, though, their appeal to black farmers stimulated their political rivals to suppress the black vote for decades and set black and poor white farmers against each other, tightening segregation. Aspects of the Populists ideas re-emerged effectively in Roosevelt's New Deal, even if they are mainly remembered now, if at all, thanks to allegorical references in The Wizard of Oz.The caricature above is of William Jennings Bryan, Populist-backed Presidential candidate.With Lawrence Goldman Professor of History at the Institute of Historical Research, University of LondonMara Keire Lecturer in US History at the University of OxfordAndChristopher Phelps Associate Professor of American Studies at the University of NottinghamProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the life and works of Christine de Pizan, who wrote at the French Court in the late Middle Ages and was celebrated by Simone de Beauvoir as the first woman to 'take up her pen in defence of her sex.' She wrote across a broad range, and was particularly noted for challenging the depiction of women by famous writers such as Jean de Meun, author of the Romance of the Rose. She has been characterised as an early feminist who argued that women could play a much more important role in society than the one they were allotted, reflected in arguably her most important work, The Book of the City of Ladies, a response to the seemingly endless denigration of women in popular texts of the time.The image above, of Christine de Pizan lecturing, is (c)The British Library Board.

Melvyn Bragg and guests discuss enzymes, the proteins that control the speed of chemical reactions in living organisms. Without enzymes, these reactions would take place too slowly to keep organisms alive: with their actions as catalysts, changes which might otherwise take millions of years can happen hundreds of times a second. Some enzymes break down large molecules into smaller ones, like the ones in human intestines, while others use small molecules to build up larger, complex ones, such as those that make DNA. Enzymes also help keep cell growth under control, by regulating the time for cells to live and their time to die, and provide a way for cells to communicate with each other.

Melvyn Bragg and guests discuss the flourishing of the idea of Purgatory from C12th, when it was imagined as a place alongside Hell and Heaven in which the souls of sinners would be purged of those sins by fire. In the West, there were new systems put in place to pray for the souls of the dead, on a greater scale, with opportunities to buy pardons to shorten time in Purgatory. The idea was enriched with visions, some religious and some literary; Dante imagined Purgatory as a mountain in the southern hemisphere, others such as Marie de France told of The Legend of the Purgatory of Saint Patrick, in which the entrance was on Station Island in County Donegal. This idea of purification by fire had appalled the Eastern Orthodox Church and was one of the factors in the split from Rome in 1054, but flourished in the West up to the reformations of C16th when it was again particularly divisive.WithLaura Ashe Associate Professor of English and fellow of Worcester College at the University of OxfordMatthew Treherne Professor of Italian Literature at the University of LeedsandHelen Foxhall Forbes Associate Professor of Early Medieval History at Durham UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the life and work of Louis Pasteur (1822-1895) and his extraordinary contribution to medicine and science. It is said few people have saved more lives than Pasteur. A chemist, he showed that otherwise identical molecules could exist as 'left' and 'right-handed' versions and that molecules produced by living things were always left-handed. He proposed a germ theory to replace the idea of spontaneous generation. He discovered that microorganisms cause fermentation and disease. He began the process named after him, pasteurisation, heating liquids to 50-60 C to kill microbes. He saved the beer and wine industries in France when they were struggling with microbial contamination. He saved the French silk industry when he found a way of protecting healthy silkworm eggs from disease. He developed vaccines against anthrax and rabies and helped establish immunology. Many of his ideas were developed further after his lifetime, but one of his legacies was a charitable body, the Pasteur Institute, to continue research into infectious disease.With Andrew Mendelsohn Reader in the School of History at Queen Mary, University of LondonAnne Hardy Honorary Professor at the Centre for History in Public Health at the London School of Hygiene and Tropical Medicineand Michael Worboys Emeritus Professor in the History of Science, Technology and Medicine at the University of Manchester Producer: Simon Tillotson.

Melvyn Bragg and guests discuss the life and works of Emily Dickinson, arguably the most startling and original poet in America in the C19th. According to Thomas Wentworth Higginson, her correspondent and mentor, writing 15 years after her death, "Few events in American literary history have been more curious than the sudden rise of Emily Dickinson into a posthumous fame only more accentuated by the utterly recluse character of her life and by her aversion to even a literary publicity." That was in 1891 and, as more of Dickinson's poems were published, and more of her remaining letters, the more the interest in her and appreciation of her grew. With her distinctive voice, her abundance, and her exploration of her private world, she is now seen by many as one of the great lyric poets.

Melvyn Bragg and guests discuss The Battle of Lincoln on 20th May 1217, when two armies fought to keep, or to win, the English crown. This was a struggle between the Angevin and Capetian dynasties, one that followed Capetian successes over the Angevins in France. The forces of the new boy-king, Henry III, attacked those of Louis of France, the claimant backed by rebel Barons. Henry's regent, William Marshal, was almost seventy when he led the charge on Lincoln that day, and his victory confirmed his reputation as England's greatest knight. Louis sent to France for reinforcements but in August these, too, were defeated at sea, at the Battle of Sandwich. As part of the peace deal, Henry reissued Magna Carta, which King John had granted in 1215 but soon withdrawn, and Louis went home, leaving England's Anglo-French rulers more Anglo and less French than he had planned.

Melvyn Bragg and guests discuss the text and context of The Book of the Dead, also known as the Book of Coming Forth by Day, the ancient Egyptian collections of spells which were intended to help the recently deceased navigate the underworld. They flourished under the New Kingdom from C16th BC until the end of the Ptolemaic era in C1st BC, and drew on much earlier traditions from the walls of pyramids and on coffin cases. Almost 200 spells survive, though no one collection contains all of them, and one of the best known surrounds the weighing of the heart, the gods' final judgement of the deceased's life.With John Taylor Curator at the Department of Ancient Egypt and Sudan at the British MuseumKate Spence Senior Lecturer in Egyptian Archaeology at Cambridge University and Fellow of Emmanuel Collegeand Richard Parkinson Professor of Egyptology at the University of Oxford and Fellow of the Queen's CollegeProducer: Simon Tillotson.

The 13th-century English philosopher Roger Bacon is perhaps best known for his major work the Opus Maius. Commissioned by Pope Clement IV, this extensive text covered a multitude of topics from mathematics and optics to religion and moral philosophy. He is also regarded by some as an early pioneer of the modern scientific method. Bacon's erudition was so highly regarded that he came to be known as 'Doctor Mirabilis' or 'wonderful doctor'. However, he is a man shrouded in mystery. Little is known about much of his life and he became the subject of a number of strange legends, including one in which he allegedly constructed a mechanical brazen head that would predict the future.

Melvyn Bragg discusses the life and times of Rosa Luxemburg (1871-1919), 'Red Rosa', who was born in Poland under the Russian Empire and became one of the leading revolutionaries in an age of revolution. She was jailed for agitation and for her campaign against the Great War which, she argued, pitted workers against each other for the sake of capitalism. With Karl Liebknecht and other radicals, she founded the Spartacus League in the hope of ending the war through revolution. She founded the German Communist Party with Liebknecht; with the violence that followed the German Revolution of 1918, her opponents condemned her as Bloody Rosa. She and Liebknecht were seen as ringleaders in the Spartacus Revolt of 1919 and, on 15th January 1919, the Freikorps militia arrested and murdered them. While Luxemburg has faced opposition for her actions and ideas from many quarters, she went on to become an iconic figure in East Germany under the Cold War and a focal point for opposition to the Soviet-backed leadership.With Jacqueline Rose Co-Director of the Birkbeck Institute for the Humanities, Birkbeck, University of LondonMark Jones Irish Research Council fellow at the Centre for War Studies, University College Dublinand Nadine Rossol Senior lecturer in Modern European History at the University of EssexProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the life and ideas of Wolfgang Pauli (1900-1958), whose Exclusion Principle is one of the key ideas in quantum mechanics. A brilliant physicist, at 21 Pauli wrote a review of Einstein's theory of general relativity and that review is still a standard work of reference today. The Pauli Exclusion Principle proposes that no two electrons in an atom can be at the same time in the same state or configuration, and it helps explain a wide range of phenomena such as the electron shell structure of atoms. Pauli went on to postulate the existence of the neutrino, which was confirmed in his lifetime. Following further development of his exclusion principle, Pauli was awarded the Nobel Prize in Physics in 1945 for his 'decisive contribution through his discovery of a new law of Nature'. He also had a long correspondence with Jung, and a reputation for accidentally breaking experimental equipment which was dubbed The Pauli Effect.With Frank Close Fellow Emeritus at Exeter College, University of OxfordMichela Massimi Professor of Philosophy of Science at the University of EdinburghandGraham Farmelo Bye-Fellow of Churchill College, University of CambridgeProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Katsushika Hokusai (1760-1849), the Japanese artist whose views of Mt Fuji such as The Great Wave off Kanagawa (pictured) are some of the most iconic in world art. He worked as Japan was slowly moving towards greater contact with the outside world, trading with China and allowing two Dutch ships to dock each year. From these ships he picked up new synthetic colours and illustrations with Western compositions, which he incorporated in his traditional wood block prints. The quality of his images helped drive demand for prints among the highly literate Japanese public, particularly those required to travel to Edo under feudal obligations and who wanted to collect all his prints. As well as the quality of his work, Hokusai's success stems partly from his long life and career. He completed some of his most memorable works in his 70s and 80s and claimed he would not reach his best until he was 110.With Angus Lockyer Lecturer in Japanese History at SOAS University of LondonRosina Buckland Senior Curator of Japanese Collections at the National Museum of ScotlandAnd Ellis Tinios Honorary Lecturer in the School of History, University of LeedsProducer: Simon Tillotson.

Melvyn Bragg and guests discuss what is often called one of the most significant battles in history. In 480BC in the Saronic Gulf near Athens, between the mainland and the island of Salamis, a fleet of Greek allies decisively defeated a larger Persian-led fleet. This halted the further Persian conquest of Greece and, at Plataea and Mycale the next year, further Greek victories brought Persian withdrawal and the immediate threat of conquest to an end. To the Greeks, this enabled a flourishing of a culture that went on to influence the development of civilisation in Rome and, later, Europe and beyond. To the Persians, it was a reverse at the fringes of their vast empire but not a threat to their existence, as it was for the Greek states, and attention turned to quelling unrest elsewhere.With Lloyd Llewellyn-Jones Professor in Ancient History at Cardiff UniversityLindsay Allen Lecturer in Greek and Near Eastern History, King's College LondonandPaul Cartledge Emeritus Professor of Greek Culture and AG Leventis Senior Research Fellow at Clare College, University of CambridgeProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the high temperatures that marked the end of the Paleocene and start of the Eocene periods, about 50m years ago. Over c1000 years, global temperatures rose more than 5 C on average and stayed that way for c100,000 years more, with the surface of seas in the Arctic being as warm as those in the subtropics. There were widespread extinctions, changes in ocean currents, and there was much less oxygen in the sea depths. The rise has been attributed to an increase of carbon dioxide and methane in the atmosphere, though it is not yet known conclusively what the source of those gases was. One theory is that a rise in carbon dioxide, perhaps from volcanoes, warmed up the globe enough for warm water to reach the bottom of the oceans and so release methane from frozen crystals in the sea bed. The higher the temperature rose and the longer the water was warm, the more methane was released. Scientists have been studying a range of sources from this long period, from ice samples to fossils, to try to understand more about possible causes.

Melvyn Bragg and guests discuss Elizabeth Gaskell's novel North and South, published in 1855 after serialisation in Dickens' Household Words magazine. It is the story of Margaret Hale, who was raised in the South in the New Forest and London's Harley Street, and then moves North to a smokey mill town, Milton, in Darkshire. As well as Margaret's emotional life and her growing sense of independence, the novel explores the new ways of living thrown up by industrialisation, and the relationships between 'masters and men'. Many of Margaret Hale's experiences echo Gaskell's own life, as she was born in Chelsea and later moved to Manchester, and the novel has become valued for its insights into social conflicts and the changing world in which Gaskell lived.With Sally Shuttleworth Professor of English Literature at the University of OxfordDinah Birch Pro-vice Chancellor for Research and Professor of English Literature at the University of LiverpoolAndJenny Uglow Biographer of Elizabeth GaskellProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Kuiper Belt, a vast region of icy objects at the fringes of our Solar System, beyond Neptune, in which we find the dwarf planet Pluto and countless objects left over from the origins of the solar system, some of which we observe as comets. It extends from where Neptune is, which is 30 times further out than the Earth is from the Sun, to about 500 times the Earth-Sun distance. It covers an immense region of space and it is the part of the Solar System that we know the least about, because it is so remote from us and has been barely detectable by Earth-based telescopes until recent decades. Its existence was predicted before it was known, and study of the Kuiper Belt, and how objects move within it, has led to a theory that there may be a 9th planet far beyond Neptune.WithCarolin Crawford Public Astronomer at the Institute of Astronomy and Fellow of Emmanuel College, University of CambridgeMonica Grady Professor of Planetary and Space Sciences at the Open UniversityAndStephen Lowry Reader in Planetary and Space Sciences, University of KentProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Seneca the Younger, who was one of the first great writers to live his entire life in the world of the new Roman empire, after the fall of the Republic. He was a Stoic philosopher, he wrote blood-soaked tragedies, he was an orator, and he navigated his way through the reigns of Caligula, Claudius and Nero, sometimes exercising power at the highest level and at others spending years in exile. Agrippina the Younger was the one who called for him to tutor Nero, and it is thought Seneca helped curb some of Nero's excesses. He was later revered within the Christian church, partly for what he did and partly for what he was said to have done in forged letters to St Paul. His tragedies, with their ghosts and high body count, influenced Shakespeare's Titus Andronicus and Hamlet, and Kyd's Spanish Tragedy.

Melvyn Bragg and guests discuss the flourishing of maths in the early Islamic world, as thinkers from across the region developed ideas in places such as Baghdad's House of Wisdom. Among them were the Persians Omar Khayyam, who worked on equations, and Al-Khwarizmi, latinised as Algoritmi and pictured above, who is credited as one of the fathers of algebra, and the Jewish scholar Al-Samawal, who converted to Islam and worked on mathematical induction. As well as the new ideas, there were many advances drawing on Indian, Babylonian and Greek work and, thanks to the recording or reworking by mathematicians in the Islamic world, that broad range of earlier maths was passed on to western Europe for further study.With Colva Roney-Dougal Reader in Pure Mathematics at the University of St AndrewsPeter Pormann Professor of Classics & Graeco-Arabic Studies at the University of ManchesterAndJim Al-Khalili Professor of Physics at the University of SurreyProducer: Simon Tillotson.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the Northamptonshire poet John Clare who, according to one of Melvyn's guests Jonathan Bate, was 'the greatest labouring-class poet that England has ever produced'. Clare worked in a tavern, as a gardener and as a farm labourer in the early 19th century and achieved his first literary success with Poems Descriptive of Rural Life and Scenery. He was praised for his descriptions of rural England and his childhood there, and his reaction to the changes he saw in the Agricultural Revolution with its enclosures, displacement and altered, disrupted landscape. Despite poor mental health and, from middle age onwards, many years in asylums, John Clare continued to write and he is now seen as one of the great poets of his age.With Sir Jonathan Bate Provost of Worcester College, University of OxfordMina Gorji Senior Lecturer in the English Faculty and fellow of Pembroke College, Cambridgeand Simon Kövesi Professor of English Literature at Oxford Brookes UniversityProducer: Simon Tillotson.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the political philosophy of Hannah Arendt. She developed many of her ideas in response to the rise of totalitarianism in the C20th, partly informed by her own experience as a Jew in Nazi Germany before her escape to France and then America. She wanted to understand how politics had taken such a disastrous turn and, drawing on ideas of Greek philosophers as well as her peers, what might be done to create a better political life. Often unsettling, she wrote of 'the banality of evil' when covering the trial of Eichmann, one of the organisers of the Holocaust.WithLyndsey Stonebridge Professor of Modern Literature and History at the University of East AngliaFrisbee Sheffield Lecturer in Philosophy at Girton College, University of CambridgeandRobert Eaglestone Professor of Contemporary Literature and Thought at Royal Holloway, University LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the relationship between parasites and hosts, where one species lives on or in another to the benefit of the parasite but at a cost to the host, potentially leading to disease or death of the host. Typical examples are mistletoe and trees, hookworms and vertebrates, cuckoos and other birds. In many cases the parasite species do so well in or on a particular host that they reproduce much faster and can adapt to changes more efficiently, and it is thought that almost half of all animal species have a parasitic stage in their lifetime. What techniques do hosts have to counter the parasites, and what impact do parasites have on the evolution of their hosts?

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the history of Mary, Queen of Scots, who had potential to be one of the most powerful rulers in Europe, yet she was also one of the most vulnerable. In France, when she was the teenage bride to their future king, she was seen as rightful heir to the thrones of England and Ireland, as well as Queen of Scotland and one day of France, which would have been an extraordinary union. She was widowed too young, though and, a Catholic returning to Protestant Scotland, she struggled to overcome rivalries in her own country. She fled to Protestant England, where she was implicated in plots to overthrow Elizabeth, and it was Elizabeth herself who signed Mary's death warrant.

Melvyn Bragg and guests discuss Nietzsche's On The Genealogy of Morality - A Polemic, which he published in 1887 towards the end of his working life and in which he considered the price humans have paid, and were still paying, to become civilised. In three essays, he argued that having a guilty conscience was the price of living in society with other humans. He suggested that Christian morality, with its consideration for others, grew as an act of revenge by the weak against their masters, 'the blond beasts of prey', as he calls them, and the price for that slaves' revolt was endless self-loathing. These and other ideas were picked up by later thinkers, perhaps most significantly by Sigmund Freud who further explored the tensions between civilisation and the individual.WithStephen Mulhall Professor of Philosophy and a Fellow and Tutor at New College, University of OxfordFiona Hughes Senior Lecturer in Philosophy at the University of EssexAndKeith Ansell-Pearson Professor of Philosophy at the University of WarwickProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the German astronomer Johannes Kepler (1571 - 1630). Although he is overshadowed today by Isaac Newton and Galileo, he is considered by many to be one of the greatest scientists in history. The three laws of planetary motion Kepler developed transformed people's understanding of the Solar System and laid the foundations for the revolutionary ideas Isaac Newton produced later. Kepler is also thought to have written one of the first works of science fiction. However, he faced a number of challenges. He had to defend his mother from charges of witchcraft, he had few financial resources and his career suffered as a result of his Lutheran faith.

In a programme first broadcast in December 2016, Melvyn Bragg and guests discuss the craze for gin in Britain in the mid-18th century and the attempts to control it. With the arrival of William of Orange, it became an act of loyalty to drink Protestant, Dutch gin rather than Catholic brandy, and changes in tariffs made everyday beer less affordable. Within a short time, production increased and large sections of the population that had rarely or never drunk spirits before were consuming two pints of gin a week. As Hogarth indicated in his print 'Beer Street and Gin Lane' (1751) in support of the Gin Act, the damage was severe, and addiction to gin was blamed for much of the crime in cities such as London.

Melvyn Bragg and guests discuss Harriet Martineau who, from a non-conformist background in Norwich, became one of the best known writers in the C19th. She had a wide range of interests and used a new, sociological method to observe the world around her, from religion in Egypt to slavery in America and the rights of women everywhere. She popularised writing about economics for those outside the elite and, for her own popularity, was invited to the coronation of Queen Victoria, one of her readers.

Melvyn Bragg and guests discuss Giuseppe Garibaldi and the Italian Risorgimento. According to the historian AJP Taylor, Garibaldi was the only wholly admirable figure in modern history. Born in Nice in 1807, one of Garibaldi's aims in life was the unification of Italy and, in large part thanks to him, Italy was indeed united substantially in 1861 and entirely in 1870. With his distinctive red shirt and poncho, he was a hero of Romantic revolutionaries around the world. His fame was secured when, with a thousand soldiers, he invaded Sicily and toppled the monarchy in the Italian south. The Risorgimento was soon almost complete.This topic is the one chosen from over 750 different ideas suggested by listeners in October, for our yearly Listener Week.WithLucy Riall Professor of Comparative History of Europe at the European University Institute and Professor of History at Birkbeck, University of LondonEugenio Biagini Professor of Modern and Contemporary History at the University of CambridgeandDavid Laven Associate Professor of History at the University of NottinghamProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Baltic Crusades, the name given to a series of overlapping attempts to convert the pagans of North East Europe to Christianity at the point of the sword. From the 12th Century, Papal Bulls endorsed those who fought on the side of the Church, the best known now being the Teutonic Order which, thwarted in Jerusalem, founded a state on the edge of the Baltic, in Prussia. Some of the peoples in the region disappeared, either killed or assimilated, and the consequences for European history were profound.

This image: Joseph Mallord William Turner, The Fighting Temeraire, 1839 (c) The National Gallery, LondonMelvyn Bragg and guests discuss "The Fighting Temeraire", one of Turner's greatest works and the one he called his 'darling'. It shows one of the most famous ships of the age, a hero of Trafalgar, being towed up the Thames to the breakers' yard, sail giving way to steam. Turner displayed this masterpiece to a public which, at the time, was deep in celebration of the Temeraire era, with work on Nelson's Column underway, and it was an immediate success, with Thackeray calling the painting 'a national ode'.With Susan Foister Curator of Early Netherlandish, German and British Painting at the National GalleryDavid Blayney Brown Manton Curator of British Art 1790-1850 at Tate Britainand James Davey Curator of Naval History at the National Maritime MuseumProducer: Simon Tillotson.

"He who saw the Deep" are the first words of the standard version of The Epic of Gilgamesh, the subject of this discussion between Melvyn Bragg and his guests. Gilgamesh is often said to be the oldest surviving great work of literature, with origins in the third millennium BC, and it passed through thousands of years on cuneiform tablets. Unlike epics of Greece and Rome, the intact story of Gilgamesh became lost to later generations until tablets were discovered by Hormuzd Rassam in 1853 near Mosul and later translated. Since then, many more tablets have been found and much of the text has been reassembled to convey the story of Gilgamesh, king of Uruk the sheepfold, and Enkidu who the gods created to stop Gilgamesh oppressing his people. Together they fight Humbaba, monstrous guardian of the Cedar Forest, and kill the Bull of Heaven, for which the gods make Enkidu mortally ill. Gilgamesh goes on a long journey as he tries unsuccessfully to learn how to live forever, learning about the Great Deluge on the way, but his remarkable building works guarantee that his fame will last long after his death.With Andrew George Professor of Babylonian at SOAS, University of LondonFrances Reynolds Shillito Fellow in Assyriology at the Oriental Institute, University of Oxford and Fellow of St Benet's HallandMartin Worthington Lecturer in Assyriology at the University of CambridgeProducer: Simon Tillotson.

The scientist John Dalton was born in North England in 1766. Although he came from a relatively poor Quaker family, he managed to become one of the most celebrated scientists of his age. Through his work, he helped to establish Manchester as a place where not only products were made but ideas were born. His reputation during his lifetime was so high that unusually a statue was erected to him before he died. Among his interests were meteorology, gasses and colour blindness. However, he is most remembered today for his pioneering thinking in the field of atomic theory.

Melvyn Bragg and guests discuss the changes in the intellectual world of Western Europe in the 12th Century, and their origins. This was a time of Crusades, the formation of states, the start of Gothic architecture, a reconnection with Roman and Greek learning and their Arabic development and the start of the European universities, and has become known as The 12th Century Renaissance.The image above is part of Notre-Dame de la Belle-Verrière, Chartres Cathedral, from 1180.WithLaura Ashe Associate Professor of English at Worcester College, University of Oxford Elisabeth van Houts Honorary Professor of European Medieval History at the University of Cambridge and Giles Gasper Reader in Medieval History at Durham UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss plasma, the fourth state of matter after solid, liquid and gas. As over ninety-nine percent of all observable matter in the Universe is plasma, planets like ours, with so little plasma and so much solid, liquid and gas, appear all the more remarkable. On the grand scale, plasma is what the Sun is made from and, when we look into the night sky, almost everything we can see with the naked eye is made of plasma. On the smallest scale, here on Earth, scientists make plasma to etch the microchips on which we rely for so much. Plasma is in the fluorescent light bulbs above our heads and, in laboratories around the world, it is the subject of tests to create, one day, an inexhaustible and clean source of energy from nuclear fusion.With Justin Wark Professor of Physics and Fellow of Trinity College at the University of OxfordKate Lancaster Research Fellow for Innovation and Impact at the York Plasma Institute at the University of Yorkand Bill Graham Professor of Physics at Queens University, BelfastProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the origins of the Hindu goddess Lakshmi, and of the traditions that have built around her for over 3,000 years. According to the creation story of the Puranas, she came to existence in the churning of the ocean of milk. Her prominent status grew alongside other goddesses in the mainly male world of the Vedas, as female deities came to be seen as the Shakti, the energy of the gods, without which they would be powerless. Lakshmi came to represent the qualities of blessing, prosperity, fertility, beauty and good fortune and, more recently, political order, and she has a significant role in Diwali, one of the most important of the Hindu festivals.

Melvyn Bragg and guests discuss Animal Farm, which Eric Blair published under his pen name George Orwell in 1945. A biting critique of totalitarianism, particularly Stalinism, the essay sprung from Orwell's experiences fighting Fascists in Spain: he thought that all on the left were on the same side, until the dominant Communists violently suppressed the Anarchists and Trotskyists, and Orwell had to escape to France to avoid arrest. Setting his satire in an English farm, Orwell drew on the Russian Revolution of 1917, on Stalin's cult of personality and the purges. The leaders on Animal Farm are pigs, the secret police are attack dogs, the supporters who drown out debate with "four legs good, two legs bad" are sheep.At first, London publishers did not want to touch Orwell's work out of sympathy for the USSR, an ally of Britain in the Second World War, but the Cold War gave it a new audience and Animal Farm became a commercial as well as a critical success.Featuring: Steven Connor - Grace 2 Professor of English at the University of CambridgeMary Vincent - Professor of Modern European History at the University of SheffieldRobert Colls - Professor of Cultural History at De Montfort UniversityProducer: Simon TillotsonFirst broadcast on BBC Radio 4 in September 2016.

In a programme first broadcast in 2016, Melvyn Bragg and guests discuss Zeno of Elea, a pre-Socratic philosopher from c490-430 BC whose paradoxes were described by Bertrand Russell as "immeasurably subtle and profound." The best known argue against motion, such as that of an arrow in flight which is at a series of different points but moving at none of them, or that of Achilles who, despite being the faster runner, will never catch up with a tortoise with a head start. Aristotle and Aquinas engaged with these, as did Russell, yet it is still debatable whether Zeno's Paradoxes have been resolved.With Marcus du Sautoy Professor of Mathematics and Simonyi Professor for the Public Understanding of Science at the University of OxfordBarbara Sattler Lecturer in Philosophy at the University of St Andrewsand James Warren Reader in Ancient Philosophy at the University of CambridgeProducer: Simon Tillotson

Melvyn Bragg and guests discuss the development of photography in the 1830s, when techniques for 'drawing with light' evolved to the stage where, in 1839, both Louis Daguerre and William Henry Fox Talbot made claims for its invention. These followed the development of the camera obscura, and experiments by such as Thomas Wedgwood and Nicéphore Niépce, and led to rapid changes in the 1840s as more people captured images with the daguerreotype and calotype. These new techniques changed the aesthetics of the age and, before long, inspired claims that painting was now dead.WithSimon Schaffer Professor of the History of Science at the University of CambridgeElizabeth Edwards Emeritus Professor of Photographic History at De Montfort UniversityAndAlison Morrison-Low, Research Associate at National Museums ScotlandProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the history of the idea of Sovereignty, the authority of a state to govern itself and the relationship between the sovereign and the people. These ideas of external and internal sovereignty were imagined in various ways in ancient Greece and Rome, and given a name in 16th Century France by the philosopher and jurist Jean Bodin in his Six Books of the Commonwealth, where he said (in an early English translation) 'Maiestie or Soveraigntie is the most high, absolute, and perpetuall power over the citisens and subiects in a Commonweale: which the Latins cal Maiestatem, the Greeks akra exousia, kurion arche, and kurion politeuma; the Italians Segnoria, and the Hebrewes tomech shévet, that is to say, The greatest power to command.' Shakespeare also explored the concept through Richard II and the king's two bodies, Hobbes developed it in the 17th Century, and the idea of popular sovereignty was tested in the Revolutionary era in America and France.

Melvyn Bragg and guests discuss William Blake's collection of illustrated poems "Songs of Innocence and of Experience." He published Songs of Innocence first in 1789 with five hand-coloured copies and, five years later, with additional Songs of Experience poems and the explanatory phrase "Shewing the Two Contrary States of the Human Soul." Blake drew on the street ballads and improving children's rhymes of the time, exploring the open and optimistic outlook of early childhood with the darker and more cynical outlook of adult life, in which symbols such as the Lamb belong to innocence and the Tyger to experience.WithSir Jonathan Bate Provost of Worcester College, University of OxfordSarah Haggarty Lecturer at the Faculty of English and Fellow of Queens' College, University of CambridgeAndJon Mee Professor of Eighteenth-Century Studies at the University of YorkProducer: Simon Tillotson.

Melvyn Bragg and guests discuss The Bronze Age Collapse, the name given by many historians to what appears to have been a sudden, uncontrolled destruction of dominant civilizations around 1200 BC in the Aegean, Eastern Mediterranean and Anatolia. Among other areas, there were great changes in Minoan Crete, Egypt, the Hittite Empire, Mycenaean Greece and Syria. The reasons for the changes, and the extent of those changes, are open to debate and include droughts, rebellions, the breakdown of trade as copper became less desirable, earthquakes, invasions, volcanoes and the mysterious Sea Peoples.

Melvyn Bragg and guests discuss penicillin, discovered by Alexander Fleming in 1928. It is said he noticed some blue-green penicillium mould on an uncovered petri dish at his hospital laboratory, and that this mould had inhibited bacterial growth around it. After further work, Fleming filtered a broth of the mould and called that penicillin, hoping it would be useful as a disinfectant. Howard Florey and Ernst Chain later shared a Nobel Prize in Medicine with Fleming, for their role in developing a way of mass-producing the life-saving drug. Evolutionary theory predicted the risk of resistance from the start and, almost from the beginning of this 'golden age' of antibacterials, scientists have been looking for ways to extend the lifespan of antibiotics.WithLaura Piddock Professor of Microbiology at the University of BirminghamChristoph Tang Professor of Cellular Pathology and Professorial Fellow at Exeter College at the University of OxfordAndSteve Jones Emeritus Professor of Genetics at University College, LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the English mystic Margery Kempe (1373-1438) whose extraordinary life is recorded in a book she dictated, The Book of Margery Kempe. She went on pilgrimage to Jerusalem, to Rome and Santiago de Compostela, purchasing indulgences on her way, met with the anchoress Julian of Norwich and is honoured by the Church of England each 9th November. She sometimes doubted the authenticity of her mystical conversations with God, as did the authorities who saw her devotional sobbing, wailing and convulsions as a sign of insanity and dissoluteness. Her Book was lost for centuries, before emerging in a private library in 1934.The image (above), of an unknown woman, comes from a pew at Margery Kempe's parish church, St Margaret's, Kings Lynn and dates from c1375.WithMiri Rubin Professor of Medieval and Early Modern History at Queen Mary, University of LondonKatherine Lewis Senior Lecturer in History at the University of HuddersfieldAndAnthony Bale Professor of Medieval Studies at Birkbeck University of LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Abraham Lincoln's Gettysburg Address, ten sentences long, delivered at the dedication of the Soldiers' National Cemetery at Gettysburg after the Union forces had won an important battle with the Confederates. Opening with " Four score and seven years ago," it became one of the most influential statements of national purpose, asserting that America was "conceived in liberty, and dedicated to the proposition that all men are created equal" and "that this nation, under God, shall have a new birth of freedom-and that government of the people, by the people, for the people, shall not perish from the earth." Among those inspired were Martin Luther King Jr whose "I have a dream" speech, delivered at the Lincoln Memorial 100 years later, echoed Lincoln's opening words.With Catherine Clinton Denman Chair of American History at the University of Texas and International Professor at Queen's University, BelfastSusan-Mary Grant Professor of American History at Newcastle UniversityAndTim Lockley Professor of American History at the University of WarwickProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Muses and their role in Greek mythology, when they were goddesses of poetry, song, music and dance: what the Greeks called mousike, 'the art of the Muses' from which we derive our word 'music.' While the number of Muses, their origin and their roles varied in different accounts and at different times, they were consistently linked with the nature of artistic inspiration. This raised a question for philosophers then and since: was a creative person an empty vessel into which the Muses poured their gifts, at their will, or could that person do something to make inspiration flow?

Melvyn Bragg and guests discuss Titus Oates (1649-1705) who, with Israel Tonge, spread rumours of a Catholic plot to assassinate Charles II. From 1678, they went to great lengths to support their scheme, forging evidence and identifying the supposed conspirators. Fearing a second Gunpowder Plot, Oates' supposed revelations caused uproar in London and across the British Isles, with many Catholics, particularly Jesuit priests, wrongly implicated by Oates and then executed. Anyone who doubted him had to keep quiet, to avoid being suspected a sympathiser and thrown in prison. Oates was eventually exposed, put on trial under James II and sentenced by Judge Jeffreys to public whipping through the streets of London, but the question remained: why was this rogue, who had faced perjury charges before, ever believed?WithClare Jackson Senior Tutor and Director of Studies in History at Trinity Hall, University of CambridgeMark Knights Professor of History at the University of WarwickAndPeter Hinds Associate Professor of English at Plymouth UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Tess of the d'Urbervilles by Thomas Hardy, originally serialised in The Graphic in 1891 and, with some significant changes, published as a complete novel in 1892. The book was controversial even before serialisation, rejected by one publisher as too overtly sexual, to which a second added it did not publish 'stories where the plot involves frequent and detailed reference to immoral situations.' Hardy's description of Tess as 'A Pure Woman' in 1892 incensed some Victorian readers. He resented having to censor some of his scenes in the early versions, including references to Tess's baby following her rape by Alec d'Urberville, and even to a scene where Angel Clare lifted four milkmaids over a flooded lane (substituting transportation by wheelbarrow).The image above, from the 1891 edition, is captioned 'It Was Not Till About Three O'clock That Tess Raised Her Eyes And Gave A Momentary Glance Round.

Melvyn Bragg and guests discuss Euclid's Elements, a mathematical text book attributed to Euclid and in use from its appearance in Alexandria, Egypt around 300 BC until modern times, dealing with geometry and number theory. It has been described as the most influential text book ever written. Einstein had a copy as a child, which he treasured, later saying "If Euclid failed to kindle your youthful enthusiasm, then you were not born to be a scientific thinker."With Marcus du Sautoy Professor of Mathematics and Simonyi Professor for the Public Understanding of Science at the University of OxfordSerafina Cuomo Reader in Roman History at Birkbeck University of LondonAnd June Barrow-Green Professor of the History of Mathematics at the Open UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the impact of the eruption of Mt Tambora, in 1815, on the Indonesian island of Sambawa. This was the largest volcanic eruption in recorded history and it had the highest death toll, devastating people living in the immediate area. Tambora has been linked with drastic weather changes in North America and Europe the following year, with frosts in June and heavy rains throughout the summer in many areas. This led to food shortages, which may have prompted westward migration in America and, in a Europe barely recovered from the Napoleonic Wars, led to widespread famine.

Melvyn Bragg and guests discuss the neutron, one of the particles found in an atom's nucleus. Building on the work of Ernest Rutherford, the British physicist James Chadwick won the Nobel Prize for Physics for his discovery of the neutron in 1932. Neutrons play a fundamental role in the universe and their discovery was at the heart of developments in nuclear physics in the first half of the 20th century.

Melvyn Bragg and guests discuss the rise of the Sikh Empire at the end of the 18th Century under Ranjit Singh, pictured above, who unified most of the Sikh kingdoms following the decline of the Mughal Empire. He became Maharaja of the Punjab at Lahore in 1801, capturing Amritsar the following year. His empire flourished until 1839, after which a decade of unrest ended with the British annexation. At its peak, the Empire covered the Punjab and stretched from the Khyber Pass in the west to the edge of Tibet in the east, up to Kashmir and down to Mithankot on the Indus River. Ranjit Singh is still remembered as "The Lion of the Punjab."With Gurharpal Singh Professor in Inter-Religious Relations and Development at SOAS, University of LondonChandrika Kaul Lecturer in Modern History at the University of St AndrewsAndSusan Stronge Senior Curator in the Asian Department of the Victoria and Albert MuseumProducer: Simon Tillotson.

Agrippina the Younger was one of the most notorious and influential of the Roman empresses in the 1st century AD. She was the sister of the Emperor Caligula, a wife of the Emperor Claudius and mother of the Emperor Nero. Through careful political manoeuvres, she acquired a dominant position for herself in Rome. In 39 AD she was exiled for allegedly participating in a plot against Caligula and later it was widely thought that she killed Claudius with poison. When Nero came to the throne, he was only 16 so Agrippina took on the role of regent until he began to exert his authority. After relations between Agrippina and Nero soured, he had her murdered.With:Catharine Edwards Professor of Classics and Ancient History at Birkbeck, University of LondonAlice König Lecturer in Latin and Classical Studies at the University of St AndrewsMatthew Nicholls Associate Professor of Classics at the University of ReadingProducer: Victoria Brignell.

Melvyn Bragg and guests discuss Elizabeth Barrett Browning's epic "Aurora Leigh" which was published in 1856. It is the story of an orphan, Aurora, born in Italy to an English father and Tuscan mother, who is brought up by an aunt in rural Shropshire. She has a successful career as a poet in London and, when living in Florence, is reunited with her cousin, Romney Leigh, whose proposal she turned down a decade before. The poem was celebrated by other poets and was Elizabeth Barrett Browning's most commercially successful. Over 11,000 lines, she addressed many Victorian social issues, including reform, illegitimacy, the pressure to marry and what women must overcome to be independent, successful writers, in a world dominated by men.

Melvyn Bragg and guests discuss the early years of Bedlam, the name commonly used for the London hospital of St Mary of Bethlehem outside Bishopsgate, described in 1450 by the Lord Mayor of London as a place where may "be found many men that be fallen out of their wit. And full honestly they be kept in that place; and some be restored onto their wit and health again. And some be abiding therein for ever." As Bethlem, or Bedlam, it became a tourist attraction in the 17th Century at its new site in Moorfields and, for its relatively small size, made a significant impression on public attitudes to mental illness. The illustration, above, is from the eighth and final part of Hogarth's 'A Rake's Progress' (1732-3), where Bedlam is the last stage in the decline and fall of a young spendthrift,Tom Rakewell.With Hilary Marland Professor of History at the University of WarwickJustin Champion Professor of the History of Early Modern Ideas at Royal Holloway, University of London and President of the Historical AssociationAndJonathan Andrews Reader in the History of Psychiatry at Newcastle UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Maya Civilization, developed by the Maya people, which flourished in central America from around 250 AD in great cities such as Chichen Itza and Uxmal with advances in mathematics, architecture and astronomy. Long before the Spanish Conquest in the 16th Century, major cities had been abandoned for reasons unknown, although there are many theories including overpopulation and changing climate. The hundreds of Maya sites across Belize, El Salvador, Guatemala, Honduras and Mexico raise intriguing questions about one of the world's great pre-industrial civilizations.WithElizabeth Graham Professor of Mesoamerican Archaeology at University College LondonMatthew Restall Edwin Erle Sparks Professor of Latin American History and Anthropology at Pennsylvania State UniversityAndBenjamin Vis Eastern ARC Research Fellow in Digital Humanities at the University of KentProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Vereenigde Oost-Indische Compagnie or VOC, known in English as the Dutch East India Company. The VOC dominated the spice trade between Asia and Europe for two hundred years, with the British East India Company a distant second. At its peak, the VOC had a virtual monopoly on nutmeg, mace, cloves and cinnamon, displacing the Portuguese and excluding the British, and were the only European traders allowed access to Japan.With Anne Goldgar Reader in Early Modern European History at King's College LondonChris Nierstrasz Lecturer in Global History at Erasmus University, Rotterdam, formerly at the University of WarwickAndHelen Paul Lecturer in Economics and Economic History at the University of SouthamptonProducer: Simon Tillotson.

Mary Magdalene is one of the best-known figures in the Bible and has been a frequent inspiration to artists and writers over the last 2000 years. According to the New Testament, she was at the foot of the cross when Jesus was crucified and was one of the first people to see Jesus after the resurrection. However, her identity has provoked a large amount of debate and in the Western Church she soon became conflated with two other figures mentioned in the Bible, a repentant sinner and Mary of Bethany. Texts discovered in the mid-20th century provoked controversy and raised further questions about the nature of her relations with Jesus.With:Joanne Anderson Lecturer in Art History at the Warburg Institute, School of Advanced Study, University of LondonEamon Duffy Emeritus Professor of the History of Christianity at the University of Cambridge and Fellow of Magdalene CollegeJoan Taylor Professor of Christian Origins and Second Temple Judaism at King's College LondonProducer: Victoria Brignell.

Melvyn Bragg and guests discuss the life and work of Robert Hooke (1635-1703) who worked for Robert Boyle and was curator of experiments at the Royal Society. The engraving of a flea, above, is taken from his Micrographia which caused a sensation when published in 1665. Sometimes remembered for his disputes with Newton, he studied the planets with telescopes and snowflakes with microscopes. He was an early proposer of a theory of evolution, discovered light diffraction with a wave theory to explain it and felt he was rarely given due credit for his discoveries.

Melvyn Bragg and guests discuss the poetry of Rumi, the Persian scholar and Sufi mystic of the 13th Century. His great poetic works are the Masnavi or "spiritual couplets" and the Divan, a collection of thousands of lyric poems. He is closely connected with four modern countries: Afghanistan, as he was born in Balkh, from which he gains the name Balkhi; Uzbekistan from his time in Samarkand as a child; Iran as he wrote in Persian; and Turkey for his work in Konya, where he spent most of his working life and where his followers established the Mevlevi Order, also known as the Whirling Dervishes.With Alan Williams British Academy Wolfson Research Professor at the University of ManchesterCarole Hillenbrand Professor of Islamic History at the University of St Andrews and Professor Emerita of Edinburgh UniversityAnd Lloyd Ridgeon Reader in Islamic Studies at the University of GlasgowProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the origins, development and uses of chromatography. In its basic form, it is familiar to generations of schoolchildren who put a spot of ink at the bottom of a strip of paper, dip it in water and then watch the pigments spread upwards, revealing their separate colours. Chemists in the 19th Century started to find new ways to separate mixtures and their work was taken further by Mikhail Tsvet, a Russian-Italian scientist who is often credited with inventing chromatography in 1900. The technique has become so widely used, it is now an integral part of testing the quality of air and water, the levels of drugs in athletes, in forensics and in the preparation of pharmaceuticals.WithAndrea Sella Professor of Chemistry at University College LondonApryll Stalcup Professor of Chemical Sciences at Dublin City UniversityAndLeon Barron Senior Lecturer in Forensic Science at King's College London.

Melvyn Bragg and guests discuss the life, times and influence of Eleanor of Aquitaine (c1122-1204) who was one of the most powerful women in Twelfth Century Europe, possibly in the entire Middle Ages. She inherited land from the Loire down to the Pyrenees, about a third of modern France. She married first the King of France, Louis VII, joining him on the Second Crusade. She became stronger still after their marriage was annulled, as her next husband, Henry Plantagenet became Henry II of England. Two of their sons, Richard and John, became kings and she ruled for them when they were abroad. By her death in her eighties, Eleanor had children and grandchildren in power across western Europe. This led to competing claims of inheritance and, for much of the next 250 years, the Plantagenet and French kings battled over Eleanor's land.WithLindy Grant Professor of Medieval History at the University of ReadingNicholas Vincent Professor of Medieval History at the University of East AngliaAndJulie Barrau University Lecturer in British Medieval History at the University of CambridgeProducer: Simon Tillotson.

Melvyn Bragg and guests discuss Thomas Paine and his pamphlet "Common Sense" which was published in Philadelphia in January 1776 and promoted the argument for American independence from Britain. Addressed to The Inhabitants of America, it sold one hundred and fifty thousand copies in the first few months and is said, proportionately, to be the best-selling book in American history. Paine had arrived from England barely a year before. He vigorously attacked monarchy generally and George the Third in particular. He argued the colonies should abandon all hope of resolving their dispute with Britain and declare independence immediately. Many Americans were scandalised. More were inspired and, for Paine's vision of America's independent future, he has been called a Founding Father of the United States.With Kathleen Burk Professor Emerita of Modern and Contemporary History at University College LondonNicholas Guyatt University Lecturer in American History at the University of CambridgeAndPeter Thompson Associate Professor of American History at the University of Oxford and Fellow of St Cross CollegeProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the planet Saturn with its rings of ice and rock and over 60 moons. In 1610, Galileo used an early telescope to observe Saturn, one of the brightest points in the night sky, but could not make sense of what he saw: perhaps two large moons on either side. When he looked a few years later, those supposed moons had disappeared. It was another forty years before Dutch scientist Christiaan Huygens solved the mystery, realizing the moons were really a system of rings. Successive astronomers added more detail, with the greatest leaps forward in the last forty years. The Pioneer 11 spacecraft and two Voyager missions have flown by, sending back the first close-up images, and Cassini is still there, in orbit, confirming Saturn, with its rings and many moons, as one of the most intriguing and beautiful planets in our Solar System. WithCarolin Crawford Public Astronomer at the Institute of Astronomy and Fellow of Emmanuel College, University of CambridgeMichele Dougherty Professor of Space Physics at Imperial College LondonAndAndrew Coates Deputy Director in charge of the Solar System at the Mullard Space Science Laboratory at UCL.

Melvyn Bragg and guests discuss Tristan and Iseult, one of the most popular stories of the Middle Ages. From roots in Celtic myth, it passed into written form in Britain a century after the Norman Conquest and almost immediately spread throughout northern Europe. It tells of a Cornish knight and an Irish queen, Tristan and Iseult, who accidentally drink a love potion, at the same time, on the same boat, travelling to Cornwall. She is due to marry Tristan's king, Mark. Tristan and Iseult seemed ideally matched and their love was heroic, but could that excuse their adultery, in the minds of medieval listeners, particularly when the Church was so clear they were wrong?WithLaura Ashe Associate Professor of English at Worcester College, University of OxfordJuliette Wood Associate Lecturer in the School of Welsh at Cardiff UniversityAndMark Chinca Reader in Medieval German Literature at the University of CambridgeProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the eminent 19th-century scientist Michael Faraday. Born into a poor working-class family, he received little formal schooling but became interested in science while working as a bookbinder's apprentice. He is celebrated today for carrying out pioneering research into the relationship between electricity and magnetism. Faraday showed that if a wire was turned in the presence of a magnet or a magnet was turned in relation to a wire, an electric current was generated. This ground-breaking discovery led to the development of the electric generator and ultimately to modern power stations. During his life he became the most famous scientist in Britain and he played a key role in founding the Royal Institution's Christmas lectures which continue today.With:Geoffrey Cantor Professor Emeritus of the History of Science at the University of LeedsLaura Herz Professor of Physics at the University of OxfordFrank James Professor of the History of Science at the Royal InstitutionProducer: Victoria Brignell.

Melvyn Bragg and his guests discuss the evolution and role of Circadian Rhythms, the so-called body clock that influences an organism's daily cycle of physical, behavioural and mental changes. The rhythms are generated within organisms and also in response to external stimuli, mainly light and darkness. They are found throughout the living world, from bacteria to plants, fungi to animals and, in humans, are noticed most clearly in sleep patterns. WithRussell Foster Professor of Circadian Neuroscience at the University of OxfordDebra Skene Professor of Neuroendocrinology at the University of SurreyAndSteve Jones Emeritus Professor of Genetics at University College London.

Melvyn Bragg and guests discuss the origins and rise of Legalism in China, from the start of the Warring States Period (c475 - 221 BC) to the time of The First Emperor Qin Shi Huang (pictured), down to Chairman Mao and the present day. Advanced by the Qin statesman Shang Yang and later blended together by Han Fei, the three main aspects of Legalism were the firm implementation of laws, use of techniques such as responsibility and inscrutability, and taking advantage of the ruler's position. The Han dynasty that replaced the Qin discredited this philosophy for its apparent authoritarianism, but its influence continued, re-emerging throughout Chinese history.WithFrances Wood Former Curator of the Chinese Collections at the British LibraryHilde de Weerdt Professor of Chinese History at Leiden UniversityAndRoel Sterckx Joseph Needham Professor of Chinese History at the University of Cambridge.Producer: Simon Tillotson.

Melvyn Bragg and guests discuss the scientific advances made in the three voyages of Captain James Cook, from 1768 to 1779. Cook's voyages astonished Europeans, bringing back detailed knowledge of the Pacific and its people, from the Antarctic to the Bering Straits. This topic is one of more than a thousand different ideas suggested by listeners in October and came from Alysoun Hodges in the UK, Fiachra O'Brolchain in Ireland, Mhairi Mackay in New Zealand, Enzo Vozzo in Australia, Jeff Radford in British Columbia and Mark Green in Alaska.

Melvyn Bragg and guests discuss the outbreak of witch trials in Massachusetts in 1692-3, centred on Salem, which led to the execution of twenty people, with more dying in prison before or after trial. Some were men, including Giles Corey who died after being pressed with heavy rocks, but the majority were women. At its peak, around 150 people were suspected of witchcraft, including the wife of the governor who had established the trials. Many of the claims of witchcraft arose from personal rivalries in an area known for unrest, but were examined and upheld by the courts at a time of mass hysteria, belief in the devil, fear of attack by Native Americans and religious divisions.With Susan Castillo-Street Harriet Beecher Stowe Professor Emerita of American Studies at King's College LondonSimon Middleton Senior Lecturer in American History at the University of SheffieldAnd Marion Gibson Professor of Renaissance and Magical Literatures at Exeter University, Penryn Campus.Producer: Simon Tillotson.

"Emma Woodhouse, handsome, clever, and rich, with a comfortable home and happy disposition, seemed to unite some of the best blessings of existence; and had lived nearly twenty-one years in the world with very little to distress or vex her." So begins Emma by Jane Austen, describing her leading character who, she said, was "a heroine whom no-one but myself will much like." Melvyn Bragg and guests discuss this, one of Austen's most popular novels and arguably her masterpiece, a brilliantly sparkling comedy of manners published in December 1815 by John Murray, the last to be published in Austen's lifetime. This followed Sense and Sensibility (1811), Pride and Prejudice (1813) and Mansfield Park (1814), with her brother Henry handling publication of Northanger Abbey and Persuasion (1817).

Melvyn Bragg and guests discuss The Battle of Lepanto, 1571, the last great sea battle between galleys, in which the Catholic fleet of the Holy League of principally Venice, Spain, the Papal States, Malta, Genoa, and Savoy defeated the Ottoman forces of Selim II. When much of Europe was divided over the Reformation, this was the first major victory of a Christian force over a Turkish fleet. The battle followed the Ottoman invasion of Venetian Cyprus and decades in which the Venetians had been trying to stop the broader westward expansion of the Ottomans into the Mediterranean. The outcome had a great impact on morale in Europe and Pope Pius V established a feast day of Our Lady of Victory. Some historians call it the most significant sea battle since Actium (31 BC). However, the Ottomans viewed the loss as less significant than their victory in Cyprus and, within two years, the Holy League had broken up.WithDiarmaid MacCulloch Professor of the History of the Church at the University of OxfordKate Fleet Director of the Skilliter Centre for Ottoman Studies and Fellow of Newnham College, University of CambridgeAndNoel Malcolm A Senior Research Fellow in History at All Soul's College, University of Oxford Producer: Simon Tillotson.

Melvyn Bragg and guests discuss the problem of P versus NP, which has a bearing on online security. There is a $1,000,000 prize on offer from the Clay Mathematical Institute for the first person to come up with a complete solution. At its heart is the question "are there problems for which the answers can be checked by computers, but not found in a reasonable time?" If the answer to that is yes, then P does not equal NP. However, if all answers can be found easily as well as checked, if only we knew how, then P equals NP. The area has intrigued mathematicians and computer scientists since Alan Turing, in 1936, found that it's impossible to decide in general whether an algorithm will run forever on some problems. Resting on P versus NP is the security of all online transactions which are currently encrypted: if it transpires that P=NP, if answers could be found as easily as checked, computers could crack passwords in moments.With Colva Roney-Dougal Reader in Pure Mathematics at the University of St AndrewsTimothy Gowers Royal Society Research Professor in Mathematics at the University of CambridgeAnd Leslie Ann Goldberg Professor of Computer Science and Fellow of St Edmund Hall, University of OxfordProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Empire of Mali which flourished from 1200 to 1600 and was famous in the wider world for the wealth of rulers such as Mansa Musa. Mali was the largest empire in west Africa and for almost 400 years controlled the flow of gold from mines in the south up to the Mediterranean coast and across to the Middle East. These gold mines were the richest known deposits in the 14th Century and produced around half of the world's gold. When Mansa Musa journeyed to Cairo in 1324 as part of his Hajj, he distributed so much gold that its value depreciated by over 10%. Some of the mosques he built on his return survive, albeit rebuilt, such as the UNESCO World Heritage Site of the Great Mosque of Djenne. With Amira Bennison Reader in the History and Culture of the Maghrib at the University of CambridgeMarie Rodet Senior Lecturer in the History of Africa at SOASAndKevin MacDonald Professor of African Archaeology Chair of the African Studies Programme at University College, London Producer: Simon Tillotson.

Melvyn Bragg and guests discuss Simone de Beauvoir. "One is not born, but rather becomes, a woman," she wrote in her best known and most influential work, The Second Sex, her exploration of what it means to be a woman in a world defined by men. Published in 1949, it was an immediate success with the thousands of women who bought it. Many male critics felt men came out of it rather badly. Beauvoir was born in 1908 to a high bourgeois family and it was perhaps her good fortune that her father lost his money when she was a girl. With no dowry, she pursued her education in Paris to get work and in a key exam to allow her to teach philosophy, came second only to Jean Paul Sartre. He was retaking. They became lovers and, for the rest of their lives together, intellectual sparring partners. Sartre concentrated on existentialist philosophy; Beauvoir explored that, and existentialist ethics, plus the novel and, increasingly in the decades up to her death in 1986, the situation of women in the world.

Melvyn Bragg and guests discuss the life and work of Hans Holbein the Younger (1497-1543) during his two extended stays in England, when he worked at the Tudor Court and became the King's painter. Holbein created some of the most significant portraits of his age, including an image of Henry VIII, looking straight at the viewer, hands on hips, that has dominated perceptions of him since. The original at Whitehall Palace was said to make visitors tremble at its majesty. Holbein was later sent to Europe to paint the women who might be Henry's fourth wife; his depiction of Anne of Cleves was enough to encourage Henry to marry her, a decision Henry quickly regretted and for which Thomas Cromwell, her supporter, was executed. His paintings still shape the way we see those in and around the Tudor Court, including Cromwell, Thomas More, the infant Prince Edward (of which there is a detail, above), The Ambassadors and, of course, Henry the Eighth himself.WithSusan Foister Curator of Early Netherlandish, German and British Painting at the National GalleryJohn Guy A fellow of Clare College, University of CambridgeAndMaria Hayward Professor of Early Modern History at the University of SouthamptonProducer: Simon Tillotson.

Alexander the Great is one of the most celebrated military commanders in history. Born into the Macedonian royal family in 356 BC, he gained control of Greece and went on to conquer the Persian Empire, defeating its powerful king, Darius III. At its peak, Alexander's empire covered modern Turkey, Syria, Egypt, Iran, Iraq, Afghanistan, Pakistan and part of India. As a result, Greek culture and language was spread into regions it had not penetrated before, and he is also remembered for founding a number of cities. Over the last 2,000 years, the legend of Alexander has grown and he has influenced numerous generals and politicians.With:Paul Cartledge Emeritus Professor of Greek Culture and AG Leventis Senior Research Fellow at Clare College, University of CambridgeDiana Spencer Professor of Classics at the University of BirminghamRachel Mairs Lecturer in Classics at the University of ReadingProducer: Victoria Brignell.

Melvyn Bragg and guests discuss the rise of the idea of perpetual motion and its decline, in the 19th Century, with the Laws of Thermodynamics. For hundreds of years, some of the greatest names in science thought there might be machines that could power themselves endlessly. Leonardo Da Vinci tested the idea of a constantly-spinning wheel and Robert Boyle tried to recirculate water from a draining flask. Gottfried Leibniz supported a friend, Orffyreus, who claimed he had built an ever-rotating wheel. An increasing number of scientists voiced their doubts about perpetual motion, from the time of Galileo, but none could prove it was impossible. For scientists, the designs were a way of exploring the laws of nature. Others claimed their inventions actually worked, and promised a limitless supply of energy. It was not until the 19th Century that the picture became clearer, with the experiments of James Joule and Robert Mayer on the links between heat and work, and the establishment of the First and Second Laws of Thermodynamics.With Ruth Gregory Professor of Mathematics and Physics at Durham UniversityFrank Close Professor Emeritus of Physics at the University of OxfordandSteven Bramwell Professor of Physics and former Professor of Chemistry at University College LondonProducer: Simon Tillotson.

Born near Mexico City in 1907, Frida Kahlo is considered one of Mexico's greatest artists. She took up painting after a bus accident left her severely injured, was a Communist, married Diego Rivera, a celebrated muralist, became friends with Trotsky and developed an iconic series of self-portraits. Her work brings together elements such as surrealism, pop culture, Aztec and Indian mythology and commentary on Mexican culture. In 1938, artist and poet Andre Breton organised an exhibition of her work in New York, writing in the catalogue, "The Art of Frida Kahlo is a ribbon around a bomb." She was not as widely appreciated during her lifetime as she has since become, but is now one of the most recognised artists of the 20th century.

Frederick the Great ruled Prussia from 1740 until his death in 1786. Born in 1712, he increased the power of the state, he made Prussia the leading military power in Europe and his bold campaigns had great implications for the European political landscape. An absolute monarch in the age of enlightenment, he was a prolific writer, attracted figures such as Voltaire to his court, fostered education and put Berlin firmly on the cultural map. He was much admired by Napoleon and was often romanticised by German historians, becoming a hero for many in united Germany in the 19th and 20th centuries. Others, however, vilified him for aspects such as his militarism and the partition of Poland.

In 1977, scientists in the submersible "Alvin" were exploring the deep ocean bed off the Galapagos Islands. In the dark, they discovered hydrothermal vents, like chimneys, from which superheated water flowed. Around the vents there was an extraordinary variety of life, feeding on microbes which were thriving in the acidity and extreme temperature of the vents. While it was already known that some microbes are extremophiles, thriving in extreme conditions, such as the springs and geysers of Yellowstone Park (pictured), that had not prepared scientists for what they now found. Since the "Alvin" discovery, the increased study of extremophile microbes has revealed much about what is and is not needed to sustain life on Earth and given rise to new theories about how and where life began. It has also suggested forms and places in which life might be found elsewhere in the Universe.

The story of Jane Eyre is one of the best-known in English fiction. Jane is the orphan who survives a miserable early life, first with her aunt at Gateshead Hall and then at Lowood School. She leaves the school for Thornfield Hall, to become governess to the French ward of Mr Rochester. She and Rochester fall in love but, at their wedding, it is revealed he is married already and his wife, insane, is kept in Thornfield's attic. When Jane Eyre was published in 1847, it was a great success and brought fame to Charlotte Bronte. Combined with Gothic mystery and horror, the book explores many themes, including the treatment of children, relations between men and women, religious faith and hypocrisy, individuality, morality, equality and the nature of true love.

A moral theory that emphasises ends over means, Utilitarianism holds that a good act is one that increases pleasure in the world and decreases pain. The tradition flourished in the eighteenth and nineteenth centuries with Jeremy Bentham and John Stuart Mill, and has antecedents in ancient philosophy. According to Bentham, happiness is the means for assessing the utility of an act, declaring "it is the greatest happiness of the greatest number that is the measure of right and wrong." Mill and others went on to refine and challenge Bentham's views and to defend them from critics such as Thomas Carlyle, who termed Utilitarianism a "doctrine worthy only of swine."WithMelissa Lane The Class of 1943 Professor of Politics at Princeton UniversityJanet Radcliffe Richards Professor of Practical Philosophy at the University of OxfordandBrad Hooker A Professor of Philosophy at the University of ReadingProducer: Simon Tillotson.

In the Middle Ages, Prester John was seen as the great hope for Crusaders struggling to hold on to, then regain, Jerusalem. He was thought to rule a lost Christian kingdom somewhere in the East and was ready to attack Muslim opponents with his enormous armies. There was apparent proof of Prester John's existence, in letters purportedly from him and in stories from travelers who claimed they had met, if not him, then people who had news of him. Most pointed to a home in the earthly paradise in the Indies, outside Eden, with fantastical animals and unimaginable riches. Later, Portuguese explorers thought they had found him in Ethiopia, despite the mystified denials of people there. Melvyn Bragg asks why the legend was so strongly believed for so long, and what facts helped sustain the myths.WithMarianne O'Doherty Associate Professor in English at the University of SouthamptonMartin Palmer Director of the International Consultancy on Religion, Education, and CultureAndAmanda Power Senior Lecturer in Medieval History at the University of Sheffield.Producer: Simon Tillotson.

While glass items have been made for at least 5,000 years, scientists are yet to explain, conclusively, what happens when the substance it's made from moves from a molten state to its hard, transparent phase. It is said to be one of the great unsolved problems in physics. While apparently solid, the glass retains certain properties of a liquid. At times, ways of making glass have been highly confidential; in Venice in the Middle Ages, disclosure of manufacturing techniques was a capital offence. Despite the complexity and mystery of the science of glass, glass technology has continued to advance from sheet glass to crystal glass, optical glass and prisms, to float glasses, chemical glassware, fibre optics and metal glasses.With:Dame Athene Donald Professor of Experimental Physics at the University of Cambridge and Master of Churchill College, CambridgeJim Bennett Former Director of the Museum of the History of Science at the University of Oxford and Keeper Emeritus at the Science MuseumPaul McMillan Professor of Chemistry at University College LondonProducer: Simon Tillotson.

It is said that, in Britain from the 18th Century, copies of Josephus' works were as widespread and as well read as The Bible. Christians valued "The Antiquities of the Jews" in particular, for the retelling of parts of the Old Testament and apparently corroborating the historical existence of Jesus. Born Joseph son of Matthias, in Jerusalem, in 37AD, he fought the Romans in Galilee in the First Jewish-Roman War. He was captured by Vespasian's troops and became a Roman citizen, later describing the siege and fall of Jerusalem. His actions and writings made him a controversial figure, from his lifetime to the present day.WithTessa Rajak Professor Emeritus of Ancient History, University of ReadingPhilip Alexander Professor Emeritus of Jewish Studies, University of ManchesterAndMartin Goodman Professor of Jewish Studies, University of Oxford and President of the Oxford Centre for Hebrew and Jewish StudiesProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Cotton Famine in Lancashire from 1861-65. The Famine followed the blockade of Confederate Southern ports during the American Civil War which stopped the flow of cotton into mills in Britain and Europe. Reports at the time told of starvation, mass unemployment and migration. Abraham Lincoln wrote, "I know and deeply deplore the sufferings which the working-men of Manchester, and in all Europe, are called to endure in this crisis." While the full cause and extent of the Famine in Lancashire are disputed, the consequences of this and the cotton blockade were far reaching.WithLawrence Goldman Director of the Institute of Historical Research at the University of LondonEmma Griffin Professor of History at the University of East AngliaAndDavid Brown Senior Lecturer in American Studies at University of ManchesterProducer: Simon Tillotson.

Rabindranath Tagore was the first non-European to win a Nobel Prize for Literature. He has been called one of the outstanding thinkers of the 20th century and the greatest poet India has ever produced. His Nobel followed publication of Gitanjali, his English version of some of his Bengali poems. WB Yeats and Ezra Pound were great supporters. Tagore was born in Calcutta in 1861 and educated partly in Britain; King George V knighted him, but Tagore renounced this in 1919 following the Amritsar Massacre. A key figure in Indian nationalism, Tagore became a friend of Gandhi, offering criticism as well as support. A polymath and progressive, Tagore painted, wrote plays, novels, short stories and many songs. The national anthems of India and Bangladesh are based on his poems.

Melvyn Bragg and his guests discuss the Earth's Core. The inner core is an extremely dense, solid ball of iron and nickel, the size of the Moon, while the outer core is a flowing liquid, the size of Mars. Thanks to the magnetic fields produced within the core, life on Earth is possible. The magnetosphere protects the Earth from much of the Sun's radiation and the flow of particles which would otherwise strip away the atmosphere. The precise structure of the core and its properties have been fascinating scientists from the Renaissance. Recent seismographs show the picture is even more complex than we might have imagined, with suggestions that the core is spinning at a different speed and on a different axis from the surface.WithStephen Blundell Professor of Physics and Fellow of Mansfield College at the University of OxfordArwen Deuss Associate Professor in Seismology at Utrecht UniversityandSimon Redfern Professor of Mineral Physics at the University of CambridgeProducer: Simon Tillotson.

Melvyn Bragg and his guests discuss the life and work of the 18th-century novelist, playwright and diarist Fanny Burney, also known as Madame D'Arblay and Frances Burney. Her first novel, Evelina, was published anonymously and caused a sensation, attracting the admiration of many eminent contemporaries. In an era when very few women published their work she achieved extraordinary success, and her admirers included Dr Johnson and Edmund Burke; later Virginia Woolf called her 'the mother of English fiction'.With Nicole Pohl Reader in English Literature at Oxford Brookes UniversityJudith Hawley Professor of Eighteenth-Century Literature at Royal Holloway, University of LondonandJohn Mullan Professor of English at University College London.

Melvyn Bragg and his guests discuss the life of Matteo Ricci, a Jesuit priest who in the 16th century led a Christian mission to China. An accomplished scholar, Ricci travelled extensively and came into contact with senior officials of the Ming Dynasty administration. His story is one of the most important encounters between Renaissance Europe and a China which was still virtually closed to outsiders.With Mary Laven Reader in Early Modern History at the University of CambridgeCraig Clunas Professor of the History of Art at the University of OxfordandAnne Gerritsen Reader in History at the University of Warwick Producer: Simon Tillotson.

Melvyn Bragg and his guests discuss the Greek poet Sappho. Born in the late seventh century BC, Sappho spent much of her life on the island of Lesbos. In antiquity she was famed as one of the greatest lyric poets, but owing to a series of accidents the bulk of her work was lost to posterity. The fragments that do survive, however, give a tantalising glimpse of a unique voice of Greek literature. Her work has lived on in other languages, too, translated by such major poets as Ovid, Christina Rossetti and Baudelaire.WithEdith Hall Professor of Classics at King's College, LondonMargaret Reynolds Professor of English at Queen Mary, University of Londonand Dirk Obbink Professor of Papyrology and Greek Literature at the University of Oxford Fellow and tutor at Christ Church, OxfordProducer: Simon Tillotson.

Melvyn Bragg and his guests discuss the California Gold Rush. In 1849 the recent discovery of gold at Coloma, near Sacramento in California, led to a massive influx of prospectors seeking to make their fortunes. Within a couple of years the tiny settlement of San Francisco had become a major city, with tens of thousands of immigrants, the so-called Forty-Niners, arriving by boat and over land. The gold rush transformed the west coast of America and its economy, but also uprooted local populations of Native Americans and made irreversible changes to natural habitats.With:Kathleen Burk Professor of Modern and Contemporary History at University College LondonJacqueline Fear-Segal Reader in American History and Culture at the University of East AngliaFrank Cogliano Professor of American History at the University of Edinburgh.

Melvyn Bragg and his guests discuss the scientific achievements of the Curie family. In 1903 Marie and Pierre Curie shared a Nobel Prize in Physics with Henri Becquerel for their work on radioactivity, a term which Marie coined. Marie went on to win a Nobel in Chemistry eight years later; remarkably, her daughter Irène Joliot-Curie would later share a Nobel with her husband Frédéric Joliot-Curie for their discovery that it was possible to create radioactive materials in the laboratory. The work of the Curies added immensely to our knowledge of fundamental physics and paved the way for modern treatments for cancer and other illnesses.With:Patricia Fara Senior Tutor of Clare College, University of CambridgeRobert Fox Emeritus Professor of the History of Science at the University of OxfordSteven T Bramwell Professor of Physics and former Professor of Chemistry at University College LondonProducer: Simon Tillotson.

Melvyn Bragg and his guests discuss the life and work of Al-Ghazali, a major philosopher and theologian of the late 11th century. Born in Persia, he was one of the most prominent intellectuals of his age, working in such centres of learning as Baghdad, Damascus and Jerusalem. He is now seen as a key figure in the development of Islamic thought, not just refining the theology of Islam but also building on the existing philosophical tradition inherited from the ancient Greeks.With:Peter Adamson Professor of Late Ancient and Arabic Philosophy at the LMU in MunichCarole Hillenbrand Professor of Islamic History at Edinburgh and St Andrews UniversitiesRobert Gleave Professor of Arabic Studies at the University of ExeterProducer: Victoria Brignell.

Melvyn Bragg and his guests discuss dark matter, the mysterious and invisible substance which is believed to make up most of the Universe. In 1932 the Dutch astronomer Jan Oort noticed that the speed at which galaxies moved was at odds with the amount of material they appeared to contain. He hypothesized that much of this 'missing' matter was simply invisible to telescopes. Today astronomers and particle physicists are still fascinated by the search for dark matter and the question of what it is.With Carolin Crawford Public Astronomer at the Institute of Astronomy, University of Cambridge and Gresham Professor of AstronomyCarlos Frenk Ogden Professor of Fundamental Physics and Director of the Institute for Computational Cosmology at the University of DurhamAnne Green Reader in Physics at the University of NottinghamProducer: Simon Tillotson.

Melvyn Bragg and his guests discuss the epic poem Beowulf, one of the masterpieces of Anglo-Saxon literature. Composed in the early Middle Ages by an anonymous poet, the work tells the story of a Scandinavian hero whose feats include battles with the fearsome monster Grendel and a fire-breathing dragon. It survives in a single manuscript dating from around 1000 AD, and was almost completely unknown until its rediscovery in the nineteenth century. Since then it has been translated into modern English by writers including William Morris, JRR Tolkien and Seamus Heaney, and inspired poems, novels and films.With:Laura Ashe Associate Professor in English at the University of Oxford and Fellow of Worcester CollegeClare Lees Professor of Medieval English Literature and History of the Language at King's College LondonAndy Orchard Rawlinson and Bosworth Professor of Anglo-Saxon at the University of OxfordProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the history and significance of eunuchs, castrated men who were a common feature of many civilisations for at least three thousand years. Eunuchs were typically employed as servants in royal households in the ancient Middle East, China and classical antiquity. In some civilisations they were used as administrators or senior military commanders, sometimes achieving high office. The tradition lingered until surprisingly recently, with castrated singers remaining a feature of Vatican choirs until the nineteenth century, while the last Chinese eunuch of the imperial court died in 1996.With:Karen Radner Professor of Ancient Near Eastern History at University College LondonShaun Tougher Reader in Ancient History at Cardiff UniversityMichael Hoeckelmann British Academy Postdoctoral Fellow in the Department of History at King's College LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss Adam Smith's celebrated economic treatise The Wealth of Nations. Smith was one of Scotland's greatest thinkers, a moral philosopher and pioneer of economic theory whose 1776 masterpiece has come to define classical economics. Based on his careful consideration of the transformation wrought on the British economy by the Industrial Revolution, and how it contrasted with marketplaces elsewhere in the world, the book outlined a theory of wealth and how it is accumulated that has arguably had more influence on economic theory than any other.With:Richard Whatmore Professor of Modern History and Director of the Institute of Intellectual History at the University of St AndrewsDonald Winch Emeritus Professor of Intellectual History at the University of SussexHelen Paul Lecturer in Economics and Economic History at the University of SouthamptonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the photon, one of the most enigmatic objects in the Universe. Generations of scientists have struggled to understand the nature of light. In the late nineteenth century it seemed clear that light was an electromagnetic wave. But the work of physicists including Planck and Einstein shed doubt on this theory. Today scientists accept that light can behave both as a wave and a particle, the latter known as the photon. Understanding light in terms of photons has enabled the development of some of the most important technology of the last fifty years.With:Frank Close Professor Emeritus of Physics at the University of OxfordWendy Flavell Professor of Surface Physics at the University of ManchesterSusan Cartwright Senior Lecturer in Physics and Astronomy at the University of Sheffield.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss the Indian Emperor Ashoka. Active in the 3rd century BC, Ashoka conquered almost all of the landmass covered by modern-day India, creating the largest empire South Asia had ever known. After his campaign of conquest he converted to Buddhism, and spread the religion throughout his domain. His edicts were inscribed on the sides of an extraordinary collection of stone pillars spread far and wide across his empire, many of which survive today. Our knowledge of ancient India and its chronology, and how this aligns with the history of Europe, is largely dependent on this important set of inscriptions, which were deciphered only in the nineteenth century.With:Jessica Frazier Lecturer in Religious Studies at the University of Kent and a Research Fellow at the Oxford Centre for Hindu StudiesNaomi Appleton Chancellor's Fellow in Religious Studies at the University of EdinburghRichard Gombrich Founder and Academic Director of the Oxford Centre for Buddhist Studies and Emeritus Professor of Sanskrit at the University of OxfordProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the ancient Greek historian Thucydides. In the fifth century BC Thucydides wrote The History of the Peloponnesian War, an account of a conflict in which he had himself taken part. This work is now seen as one of the first great masterpieces of history writing, a book which influenced writers for centuries afterwards. Thucydides was arguably the first historian to make a conscious attempt to be objective, bringing a rational and impartial approach to his scholarship. Today his work is still widely studied at military colleges and in the field of international relations for the insight it brings to bear on complex political situations.With:Paul Cartledge Emeritus Professor of Greek Culture and AG Leventis Senior Research Fellow at Clare College, CambridgeKatherine Harloe Associate Professor in Classics and Intellectual History at the University of ReadingNeville Morley Professor of Ancient History at the University of BristolProducer: Thomas Morris.

Melvyn Bragg and guests discuss phenomenology, a style of philosophy developed by the German thinker Edmund Husserl in the first decades of the 20th century. Husserl's initial insights underwent a radical transformation in the work of his student Martin Heidegger, and played a key role in the development of French philosophy at the hands of writers like Emmanuel Levinas, Jean-Paul Sartre, Simone de Beauvoir and Maurice Merleau-Ponty.Phenomenology has been a remarkably adaptable approach to philosophy. It has given its proponents a platform to expose and critique the basic assumptions of past philosophy, and to talk about everything from the foundations of geometry to the difference between fear and anxiety. It has also been instrumental in getting philosophy out of the seminar room and making it relevant to the lives people actually lead.

Melvyn Bragg and guests discuss Pieter Bruegel the Elder's painting of 1559, 'The Fight Between Carnival And Lent'. Created in Antwerp at a time of religious tension between Catholics and Protestants, the painting is rich in detail and seems ripe for interpretation. But Bruegel is notoriously difficult to interpret. His art seems to reject the preoccupations of the Italian Renaissance, drawing instead on techniques associated with the new technology of the 16th century, print. Was Bruegel using his art to comment on the controversies of his day? If so, what comment was he making?

Melvyn Bragg and his guests discuss the philosophy of truth. Pontius Pilate famously asked: what is truth? In the twentieth century, the nature of truth became a subject of particular interest to philosophers, but they preferred to ask a slightly different question: what does it mean to say of any particular statement that it is true? What is the difference between these two questions, and how useful is the second of them?With:Simon Blackburn Fellow of Trinity College, University of Cambridge, and Professor of Philosophy at the New College of the HumanitiesJennifer Hornsby Professor of Philosophy at Birkbeck, University of LondonCrispin Wright Regius Professor of Logic at the University of Aberdeen, and Professor of Philosophy at New York UniversityProducer: Victoria Brignell and Luke Mulhall.

Melvyn Bragg and guests discuss Behavioural Ecology, the scientific study of animal behaviour.What factors influence where and what an animal chooses to eat? Why do some animals mate for life whilst others are promiscuous? Behavioural ecologists approach questions like these using Darwin's theory of natural selection, along with ideas drawn from game theory and the economics of consumer choice.Scientists had always been interested in why animals behave as they do, but before behavioural ecology this area of zoology never got much beyond a collection of interesting anecdotes. Behavioural ecology gave researchers techniques for constructing rigorous mathematical models of how animals act under different circumstances, and for predicting how they will react if circumstances change. Behavioural ecology emerged as a branch of zoology in the second half of the 20th century and proponents say it revolutionized our understanding of animals in their environments.GUESTSSteve Jones, Emeritus Professor of Genetics at University College LondonRebecca Kilner, Professor of Evolutionary Biology at the University of CambridgeJohn Krebs, Principal of Jesus College at the University of OxfordProducer: Luke Mulhall.

Melvyn Bragg and guests discuss Zen. It's often thought of as a form of Buddhism that emphasises the practice of meditation over any particular set of beliefs. In fact Zen belongs to a particular intellectual tradition within Buddhism that took root in China in the 6th century AD. It spread to Japan in the early Middle Ages, where Zen practitioners set up religious institutions like temples, monasteries and universities that remain important today.GUESTSTim Barrett, Emeritus Professor in the Department of the Study of Religions at SOAS, University of LondonLucia Dolce, Numata Reader in Japanese Buddhism at SOAS, University of LondonEric Greene, Lecturer in East Asian Religions at the University of BristolProducer: Luke Mulhall.

Melvyn Bragg and guests discuss Franz Kafka's novel of power and alienation 'The Trial', in which readers follow the protagonist Joseph K into a bizarre, nightmarish world in which he stands accused of an unknown crime; courts of interrogation convene in obscure tenement buildings; and there seems to be no escape from a crushing, oppressive bureaucracy.Kafka was a German-speaking Jew who lived in the Czech city of Prague, during the turbulent years which followed the First World War. He spent his days working as a lawyer for an insurance company, but by night he wrote stories and novels considered some of the high points of twentieth century literature. His explorations of power and alienation have chimed with existentialists, Marxists, psychoanalysts, postmodernists - and Radio 4 listeners, who suggested this as our topic for listener week on In Our Time.GUESTSElizabeth Boa, Professor Emerita of German at the University of Nottingham Steve Connor, Grace 2 Professor of English at the University of Cambridge Ritchie Robertson, Taylor Professor of the German Language and Literature at the University of OxfordProducer: Luke Mulhall.

Melvyn Bragg and guests discuss Aesop. According to some accounts, Aesop was a strikingly ugly slave who was dumb until granted the power of speech by the goddess Isis. In stories of his life he's often found outwitting his masters using clever wordplay, but he's best known today as the supposed author of a series of fables that are some of the most enduringly popular works of Ancient Greek literature. Some modern scholars question whether he existed at all, but the body of work that has come down to us under his name gives us a rare glimpse of the popular culture of the Ancient World.WITHPavlos Avlamis, Junior Research Fellow in Classics at Trinity College at the University of OxfordSimon Goldhill, Professor of Greek Literature and Culture at the University of CambridgeLucy Grig, Senior Lecturer in Classics at the University of EdinburghProducer: Luke Mulhall.

Melvyn Bragg and guests discuss Isambard Kingdom Brunel, the Victorian engineer responsible for bridges, tunnels and railways still in use today more than 150 years after they were built. Brunel represented the cutting edge of technological innovation in Victorian Britain, and his life gives us a window onto the social changes that accompanied the Industrial Revolution. Yet his work was not always successful, and his innovative approach to engineering projects was often greeted with suspicion from investors. Guests:Julia Elton, former President of the Newcomen Society for the History of Engineering and TechnologyBen Marsden, Senior Lecturer in the School of Divinity, History and Philosophy at the University of AberdeenCrosbie Smith, Professor of the History of Science at the University of KentProducer: Luke Mulhall.

Melvyn Bragg and guests discuss the Egyptian pharaoh Hatshepsut, whose name means 'foremost of noble ladies'. She ruled Egypt from about 1479 - 1458 BC and some scholars argue that she was one of the most successful and influential pharaohs. When she came to the throne, Egypt was still recovering from a period of turbulence known as the Second Intermediate Period a few generations earlier. Hatshepsut reasserted Egyptian power by building up international trade and commissioned buildings considered masterpieces of Egyptian architecture. She also made significant changes to the ideology surrounding the pharaoh and the gods. However, following her death, her name was erased from the records and left out of ancient lists of Egyptian kings.With:Elizabeth Frood Associate Professor of Egyptology at the University of OxfordKate Spence Lecturer in Egyptian Archaeology at the University of CambridgeCampbell Price Curator of Egypt and Sudan at The Manchester MuseumProducer: Victoria Brignell.

Melvyn Bragg and his guests discuss nuclear fusion, the process that powers stars. In the 1920s physicists predicted that it might be possible to generate huge amounts of energy by fusing atomic nuclei together, a reaction requiring enormous temperatures and pressures. Today we know that this complex reaction is what keeps the Sun shining. Scientists have achieved fusion in the laboratory and in nuclear weapons; today it is seen as a likely future source of limitless and clean energy.Guests:Philippa Browning, Professor of Astrophysics at the University of ManchesterSteve Cowley, Chief Executive of the United Kingdom Atomic Energy AuthorityJustin Wark, Professor of Physics and fellow of Trinity College at the University of OxfordProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Haitian Revolution. In 1791 an uprising began in the French colonial territory of St Domingue. Partly a consequence of the French Revolution and partly a backlash against the brutality of slave owners, it turned into a complex struggle involving not just the residents of the island but French, English and Spanish forces. By 1804 the former slaves had won, establishing the first independent state in Latin America and the first nation to be created as a result of a successful slave rebellion. But the revolution also created one of the world's most impoverished societies, a legacy which Haiti has struggled to escape.ContributorsKate Hodgson, Postdoctoral Research Fellow in French at the University of LiverpoolTim Lockley, Reader in American Studies at the University of WarwickKaren Salt, Fellow in History in the School of Language and Literature at the University of AberdeenProducer: Luke Mulhall.

Melvyn Bragg and his guests discuss the life and work of Rudyard Kipling. Born in Bombay in 1865, Kipling has been described as the poet of Empire, celebrated for fictional works including Kim and The Jungle Book. Today his poem 'If--' remains one of the best known in the English language. Kipling was amongst the first writers in English to develop the short story as a literary form in its own right, and was the first British recipient of a Nobel Prize for Literature. A literary celebrity of the Edwardian era, Kipling's work for the Commonwealth War Graves Commission played a major role in Britain's cultural response to the First World War.Contributors:Howard Booth, Senior Lecturer in English Literature at the University of ManchesterDaniel Karlin, Winterstoke Professor of English Literature at the University of BristolJan Montefiore, Professor of Twentieth Century English Literature at the University of KentProducer: Luke Mulhall.

Melvyn Bragg and his guests discuss the Battle of Talas, a significant encounter between Arab and Chinese forces which took place in central Asia in 751 AD. It brought together two mighty empires, the Abbasid Caliphate and the Tang Dynasty, and although not well known today the battle had profound consequences for the future of both civilisations. The Arabs won the confrontation, but the battle marks the point where the Islamic Empire halted its march eastwards, and the Chinese stopped their expansion to the west. It was also a point of cultural exchange: some historians believe that it was also the moment when the technology of paper manufacture found its way from China to the Western world.GUESTSHilde de Weerdt, Professor of Chinese History at Leiden UniversityMichael Höckelmann, British Academy Postdoctoral Fellow in the Department of History at King's College LondonHugh Kennedy, Professor of Arabic at SOAS, University of LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the life, work and reputation of Julius Caesar. Famously assassinated as he entered the Roman senate on the Ides of March, 44 BC, Caesar was an inspirational general who conquered much of Europe. He was a ruthless and canny politician who became dictator of Rome, and wrote The Gallic Wars, one of the most admired and studied works of Latin literature. Shakespeare is one of many later writers to have been fascinated by the figure of Julius Caesar.With:Christopher Pelling Regius Professor of Greek at the University of OxfordCatherine Steel Professor of Classics at the University of GlasgowMaria Wyke Professor of Latin at University College LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss Euler's number, also known as e. First discovered in the seventeenth century by the Swiss mathematician Jacob Bernoulli when he was studying compound interest, e is now recognised as one of the most important and interesting numbers in mathematics. Roughly equal to 2.718, e is useful in studying many everyday situations, from personal savings to epidemics. It also features in Euler's Identity, sometimes described as the most beautiful equation ever written.
