In Our Time

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.

After 27 years, Melvyn Bragg has decided to step down from the In Our Time presenter’s chair. With over a thousand episodes to choose from, he has selected just six that capture the huge range and depth of the subjects he and his experts have tackled. In this second of his choices, we hear Melvyn Bragg and his guests discuss one of his favourite poets.Their topic is 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 TillotsonSpanning history, religion, culture, science and philosophy, In Our Time from BBC Radio 4 is essential listening for the intellectually curious.

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

To celebrate Melvyn Bragg’s 27 years presenting In Our Time, some well-known fans of the programme have chosen their favourite episodes. Historian and broadcaster Simon Schama has selected the episode on Shakespeare’s Sonnets and recorded an introduction to it. (This introduction will be available on BBC Sounds and the In Our Time webpage shortly after the broadcast and will be longer than the one broadcast on Radio 4). In 1609 Thomas Thorpe published a collection of poems entitled 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. This object can be found at the Kimbell Art Museum in Fort Worth, Texas.With Edith Hall Professor of Classics at King’s College LondonEmily Wilson Professor of Classical Studies at the University of PennsylvaniaAndRosie Wyles Lecturer in Classical History and Literature at the University of KentProducer: Simon Tillotson

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
