In Our Time

Melvyn Bragg and his guests discuss Romulus and Remus, the central figures of the foundation myth of Rome. According to tradition, the twins were abandoned by their parents as babies, but were saved by a she-wolf who found and nursed them. Romulus killed his brother after a vicious quarrel, and went on to found a city, which was named after him.The myth has been at the core of Roman identity since the 1st century AD, although the details vary in different versions of the story. For many Roman writers, the story embodied the ethos and institutions of their civilisation. The image of the she-wolf suckling the divinely fathered twins remains a potent icon of the city even today.With:Mary Beard Professor of Classics at the University of Cambridge Peter Wiseman Emeritus Professor of Classics and Ancient History at the University of Exeter Tim Cornell Emeritus Professor of Ancient History at the University of Manchester.Producer: Thomas Morris.

Melvyn Bragg and his guests discuss comets, the 'dirty snowballs' of the Solar System. In the early 18th century the Astronomer Royal Sir Edmond Halley compiled a list of appearances of comets, bright objects like stars with long tails which are occasionally visible in the night sky. He concluded that many of these apparitions were in fact the same comet, which returns to our skies around every 75 years, and whose reappearance he correctly predicted. Halley's Comet is today the best known example of a comet, a body of ice and dust which orbits the Sun. Since they contain materials from the time when the Solar System was formed, comets are regarded by scientists as frozen time capsules, with the potential to reveal important information about the early history of our planet and others.With:Monica Grady Professor of Planetary and Space Sciences at the Open UniversityPaul Murdin Senior Fellow at the Institute of Astronomy at the University of CambridgeDon Pollacco Professor of Astronomy at the University of Warw

Melvyn Bragg and his guests discuss Thomas Malory's "Le Morte Darthur", the epic tale of King Arthur and his knights of the Round Table. Sir Thomas Malory was a knight from Warwickshire, a respectable country gentleman and MP in the 1440s who later turned to a life of crime and spent various spells in prison. It was during Malory's final incarceration that he wrote "Le Morte Darthur", an epic work which was based primarily on French, but also some English, sources. Malory died shortly after his release in 1470 and it was to be another fifteen years before "Le Morte Darthur" was published by William Caxton, to immediate popular acclaim. Although the book fell from favour in the seventeenth century, it was revived again in Victorian times and became an inspiration for the Pre-Raphaelite movement who were entranced by the chivalric and romantic world that Malory portrayed. The Arthurian legend is one of the most enduring and popular in western literature and its characters - Sir Lancelot, Guinevere, Merlin and K

Melvyn Bragg and his guests discuss the cult of Mithras, a mystery religion that existed in the Roman Empire from the 1st to the 4th centuries AD. Also known as the Mysteries of Mithras, its origins are uncertain. Academics have suggested a link with the ancient Vedic god Mitra and the Iranian Zoroastrian deity Mithra, but the extent and nature of the connection is a matter of controversy. Followers of Mithras are thought to have taken part in various rituals, most notably communal meals and a complex seven-stage initiation system. Typical depictions of Mithras show him being born from a rock, enjoying food with the sun god Sol and stabbing a bull. Mithraic places of worship have been found throughout the Roman world, including an impressive example in London. However, Mithraism went into decline in the 4th century AD with the rise of Christianity and eventually completely disappeared. In recent decades, many aspects of the cult have provoked debate, especially as there are no written accounts by its members.

Melvyn Bragg and his guests discuss The South Sea Bubble, the speculation mania in early 18th-century England which ended in the financial ruin of many of its investors. The South Sea Company was founded in 1711 with a view to restructuring government debt and restoring public credit. The company would ostensibly trade with South America, hence its name; and indeed, it did trade in slaves for the Spanish market even after the Bubble burst in 1720. People from all walks of life bought shares in the South Sea Company, from servants to gentry, and it was said the entire country was gripped by South Sea speculation mania. When the shares crashed and the company collapsed there was a public outcry and many people faced financial ruin, although some investors sold before the crash and made substantial amounts of money. For example, the bookseller Thomas Guy made his fortune and founded a hospital in his name the following year. But how did such a financial crisis develop and were there any lessons learnt following

Melvyn Bragg and his guests discuss the epic poem the Shahnameh of Ferdowsi, the 'Book of Kings', which has been at the heart of Persian culture for the past thousand years. The poem recounts a legendary history of Iran from the dawn of time to the fall of the Persian Empire in the 7th century and serves, in a sense, as a creation myth for the Persian nation. The Shahnameh took Ferdowsi thirty years to write and, consisting of over 50,000 verses, is said to be the longest poem ever written by a single author. Laced with tragedy, Ferdowsi's epic chronicles battles, romances, family rifts and Man's interior struggle with himself. Although the stories may not always be true they have a profound resonance with Iranians even today, and the poem has been referred to as both the 'encyclopaedia of Iranian culture' and the identity card of the Persian people.

Melvyn Bragg and his guests discuss the influential British philosopher Bertrand Russell. Born in 1872 into an aristocratic family, Russell is widely regarded as one of the founders of Analytic philosophy, which is today the dominant philosophical tradition in the English-speaking world. In his important book The Principles of Mathematics, he sought to reduce mathematics to logic. Its revolutionary ideas include Russell's Paradox, a problem which inspired Ludwig Wittgenstein to pursue philosophy. Russell's most significant and famous idea, the theory of descriptions, had profound consequences for the discipline.In addition to his academic work, Russell played an active role in many social and political campaigns. He supported women's suffrage, was imprisoned for his pacifism during World War I and was a founder of the Campaign for Nuclear Disarmament. He wrote a number of books aimed at the general public, including The History of Western Philosophy which became enormously popular, and in 1950 he was awarded

Melvyn Bragg and his guests discuss the history of crystallography, the study of crystals and their structure. The discovery in the early 20th century that X-rays could be diffracted by a crystal revolutionised our knowledge of materials. This crystal technology has touched most people's lives, thanks to the vital role it plays in diverse scientific disciplines - from physics and chemistry, to molecular biology and mineralogy. To date, 28 Nobel Prizes have been awarded to scientists working with X-ray crystallography, an indication of its crucial importance. The history of crystallography began with the work of Johannes Kepler in the 17th century, but perhaps the most crucial leap in understanding came with the work of the father-and-son team the Braggs in 1912. They built on the work of the German physicist Max von Laue who had proved that X-rays are a form of light waves and that it was possible to scatter these rays using a crystal. The Braggs undertook seminal experiments which transformed our perception

Melvyn Bragg and his guests discuss the Borgias, the most notorious family in Renaissance Italy. Famed for their treachery and corruption, the Borgias produced two popes during their time of dominance in Rome in the late 15th century. The most well-known of these two popes is Alexander VI, previously Cardinal Rodrigo Borgia. He was accused of buying votes to elect him to the papacy and openly promoted his children in positions of power. Rodrigo's daughter, Lucrezia, is widely remembered as a ruthless poisoner; his son, Cesare, as a brutal soldier. Murder, intrigue and power politics characterised their rule, but many of the stories now told about their depraved behaviour and evil ways emerged after their demise and gave rise to the so-called 'Black Legend'. The sullied reputation of the Borgia dynasty endures even today and their lives have provided a major theme for plays, novels and over forty films.With:Evelyn Welch Professor of Renaissance Studies at Queen Mary, University of LondonCatherine Fletcher Lect

Melvyn Bragg and his guests discuss the French philosopher and social activist Simone Weil. Born in Paris in 1909 into a wealthy, agnostic Jewish family, Weil was a precocious child and attended the prestigious Ecole Normale Superieure in Paris, achieving the top marks in her class (Simone de Beauvoir came second). Weil rejected her comfortable background and chose to work in fields and factories to experience the life of the working classes at first hand. She was acutely sensitive to human suffering and devoted her life to helping those less fortunate than herself. Despite her belief in pacifism she volunteered on the Republican side during the Spanish Civil War and later joined the French Resistance movement in England. Her philosophy was both complex and intense. She argued that the presence of evil and suffering in the world was evidence of God's love and that Man has no right to ask anything of God or of anyone whom they love. Love which expects reward was not love at all in Weil's eyes. Weil died of TB

Melvyn Bragg and his guests discuss the Upanishads, the ancient sacred texts of Hinduism. Dating from about 700 BC, the Upanishads were passed down through an oral tradition in priestly castes and were not written down until the 6th century AD. They constitute the final part of the Vedas, the collection of texts which form the foundation of the Indian Hindu world, and were originally spoken during sacrificial rituals.Yet the Upanishads go beyond incantations performed during sacrifices, and ask profound questions about human existence and man's place in the cosmos. The concepts of Brahman (the universal cosmic power) and Atman (the deeper soul of the individual) are central to the understanding of the Upanishads. Each individual treatise has its own character. Some are poetic; some are scientific; others are dialogues between kings and sages or metaphysical reflections. More than one hundred Upanishads were produced, thirteen of which are regarded as the canonical scriptures of Hinduism.With:Jessica Frazier L

Melvyn Bragg and his guests discuss The Anarchy, the civil war that took place in mid-twelfth century England. The war began as a succession dispute between the Empress Matilda, daughter of Henry I, and her cousin, Stephen of Blois. On Henry's death Stephen seized the English throne and held it for a number of years before Matilda wrestled it from him, although she was chased out of London before she could be crowned. The Anarchy dragged on for nearly twenty years and is so called because of the chaos and lawlessness that characterised the period. Yet only one major battle ever took place, the Battle of Lincoln in 1141, and any other fighting associated with the conflict was fairly localised. This has led historians to question the accuracy of labelling the civil war as The Anarchy, a name only bestowed on the era in the 19th century. But why did Matilda fail to become the monarch, and what impact did it have on the way England was ruled in centuries to come?With: John Gillingham Emeritus Professor of History

Melvyn Bragg and his guests discuss Fermat's Last Theorem. In 1637 the French mathematician Pierre de Fermat scribbled a note in the margin of one of his books. He claimed to have proved a remarkable property of numbers, but gave no clue as to how he'd gone about it. "I have found a wonderful demonstration of this proposition," he wrote, "which this margin is too narrow to contain". Fermat's theorem became one of the most iconic problems in mathematics and for centuries mathematicians struggled in vain to work out what his proof had been. In the 19th century the French Academy of Sciences twice offered prize money and a gold medal to the person who could discover Fermat's proof; but it was not until 1995 that the puzzle was finally solved by the British mathematician Andrew Wiles.

Melvyn Bragg and his guests discuss the life and influence of William Caxton, the merchant who brought the printing press to the British Isles. After spending several years working as a printer in Bruges, Caxton returned to London and in 1476 set up his first printing press in Westminster, and also imported and sold other printed books. Caxton concentrated on producing popular books that he knew would sell, such as Chaucer's 'Canterbury Tales' and small liturgical 'books of hours'. The standard of Caxton's printing may have lagged behind that on the continent, but he was a skilful businessman and unusually for printers at the time, he managed not to go bankrupt. The advent of print is now seen as one of the great revolutions in intellectual history - although many scholars believe it was a revolution that took many generations to have an effect.With:Richard Gameson Professor of the History of the Book at the University of DurhamJulia Boffey Professor of Medieval Studies in the English Department at Queen Mary

Melvyn Bragg and his guests discuss the life and achievements of Hannibal. One of the most celebrated military leaders in history, Hannibal was the Carthaginian general who led an entire army, complete with elephants, across the Alps in order to attack the Roman Republic. He lived at a time of prolonged hostility between the two great Mediterranean powers, Rome and Carthage, and was the Carthaginians' inspirational leader during the Second Punic War which unfolded between 218 and 202 BC. His career ended in defeat and exile, but he achieved such fame that even his enemies the Romans erected statues of him. Centuries later his tactical genius was admired and studied by generals including Napoleon and Wellington.With:Ellen O'Gorman Senior Lecturer in Classics at the University of BristolMark Woolmer Senior Tutor in the Department of Classics and Ancient History at the University of DurhamLouis Rawlings Senior Lecturer in Ancient History at Cardiff University.Producer: Natalia Fernandez.

Melvyn Bragg and his guests discuss the medieval scholar Gerald of Wales. Born around the middle of the twelfth century, Gerald was a cleric and courtier. For much of his life he was close to Henry II and the Church hierarchy, and wrote accounts of official journeys he made around Wales and Ireland in their service. Both Anglo-Norman and Welsh by parentage, he had a unique perspective on the political strife of his age. Gerald's Journey Around Wales and Description of Ireland are among the most colourful and informative chronicles of the Middle Ages, and had a powerful influence on later historians.With:Henrietta Leyser Emeritus Fellow of St Peter's College, University of OxfordMichelle Brown Professor Emerita of Medieval Manuscript Studies at the School of Advanced Study, University of LondonHuw Pryce Professor of Welsh History at Bangor UniversityProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Ontological Argument. In the eleventh century St Anselm of Canterbury proposed that it was possible to prove the existence of God using reason alone. His argument was ridiculed by some of his contemporaries, but was analysed and improved by later thinkers including Descartes, Spinoza and Leibniz. Other philosophers have been less kind, with the Enlightenment thinker David Hume offering one possible refutation. But the debate continued, fuelled by interventions from such heavyweights as Immanuel Kant and Kurt Gödel; and it remains one of the most discussed problems in philosophy.With:John Haldane Professor of Philosophy at the University of St AndrewsPeter Millican Professor of Philosophy at the University of OxfordClare Carlisle Lecturer in Philosophy of Religion at King's College LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the Druids, the priests of ancient Europe. Active in Ireland, Britain and Gaul, the Druids were first written about by Roman authors including Julius Caesar and Pliny, who described them as wearing white robes and cutting mistletoe with golden sickles. They were suspected of leading resistance to the Romans, a fact which eventually led to their eradication from ancient Britain. In the early modern era, however, interest in the Druids revived, and later writers reinvented and romanticised their activities. Little is known for certain about their rituals and beliefs, but modern archaeological discoveries have shed new light on them.With:Barry Cunliffe Emeritus Professor of Archaeology at the University of OxfordMiranda Aldhouse-Green Professor of Archaeology at Cardiff UniversityJustin Champion Professor of the History of Early Modern Ideas at Royal Holloway, University of LondonProducer: Thomas Morris.

Melvyn Bragg and his guests discuss the cell, the fundamental building block of life. First observed by Robert Hooke in 1665, cells occur in nature in a bewildering variety of forms. Every organism alive today consists of one or more cells: a single human body contains up to a hundred trillion of them. The first life on Earth was a single-celled organism which is thought to have appeared around three and a half billion years ago. That simple cell resembled today's bacteria. But eventually these microscopic entities evolved into something far more complex, and single-celled life gave rise to much larger, complex multicellular organisms. But how did the first cell appear, and how did that prototype evolve into the sophisticated, highly specialised cells of the human body?With:Steve Jones Professor of Genetics at University College LondonNick Lane Senior Lecturer in the Department of Genetics, Evolution and Environment, University College LondonCathie Martin Group Leader at the John Innes Centre and Professor in

Melvyn Bragg and his guests discuss Hadrian's Wall, the largest Roman structure and one of the most important archaeological monuments in Britain. Stretching for eighty miles from the mouth of the River Tyne to the Solway Firth and classified today as a World Heritage Site, it has been a source of fascination ever since it came into existence. It was built in about 122 AD by the Emperor Hadrian, and a substantial part of it still survives today. Although its construction must have entailed huge cost and labour, the Romans abandoned it within twenty years, deciding to build the Antonine Wall further north instead. Even after more than a century of excavations, many mysteries still surround Hadrian's Wall, including its exact purpose. Did it have a meaningful defensive role or was it mainly a powerful emperor's vanity project?
