Melvyn Bragg and guests discuss the legendary wizard Merlin. He was sired by an incubus and born of a virgin; he was a prophet, a shape-shifter, a king-maker and a mad man of the woods. Before Gandalf there was Merlin: the power behind Arthur and a literary sensation for centuries. In a literary career spanning 1500 years, Merlin, or originally Myrddin, put the sword in the stone, built Stonehenge, knew the truth behind the Holy Grail and discovered the Elixir of Life. "Beware Merlin for he knows all things by the devil's craft" say the poisoners in Malory's Morte D'Arthur; but he is also on the side of the good and is almost Christ-like in some of the versions of his tale, and his prophesies were pored over by the medieval Church. Who was Merlinus Ambrosius, as he is sometimes known? Where does his legend spring from and how has it been appropriated and adapted over time?With Juliette Wood, Associate Lecturer in the Department of Welsh at Cardiff University, Stephen Knight, Distinguished Research Professor in English Literature at Cardiff University, Peter Forshaw, Lecturer in Renaissance Philosophies at Birkbeck, University of London.

Melvyn Bragg and guests discuss the Scriblerus Club. The 18th century Club included some of the most extraordinary and vivid satirists ever to have written in the English language. We are given giants and midgets, implausible unions with Siamese twins, diving competitions into the open sewer of Fleet-ditch, and Olympic-style pissing competitions: "Who best can send on high/The salient spout, far streaming to the sky". But these exotic images were part of an attempt by Pope, Swift and their cadres to show a world in terrible decline: "Religion, blushing, veils her sacred fires,And unawares Morality expires.Nor public flame, nor private dares to shine;Nor human spark is left, nor glimpse divine!Lo! Thy dread empire, Chaos! Is restored:Light dies before thy uncreating word".So wrote Alexander Pope in his great mock epic verse, The Dunciad. Who were the Scriblerans? And what in eighteenth century society had driven them to such disdain and despair?With John Mullan, Senior Lecturer in English, University College London; Judith Hawley, Senior Lecturer in English, Royal Holloway, University of London; Marcus Walsh, Kenneth Allott Professor of English Literature, University of Liverpool.

Melvyn Bragg and guests discuss the story of Abelard and Heloise, a tale of literature and philosophy, theology and scandal, and above all love in the high Middle Ages. They were two of the greatest minds of their time and Abelard, a famous priest and teacher, wrote of how their affair began in his biography, Historia Calamitatum, “Her studies allowed us to withdraw in private, as love desired, and then with our books open before us, more words of love than of reading passed between us, and more kissing than teaching. My hands strayed oftener to her bosom than to the pages; love drew our eyes to look on each other more than reading kept them on our texts”. Years later, when she was an Abbess at the head of her own convent, Heloise wrote to Abelard: “Even during the celebration of Mass, when our prayers should be purer, lewd visions of those pleasures take such a hold upon my unhappy soul that my thoughts are on their wantonness instead of on prayers”. With Anthony Grayling, Professor of Philosophy at Birkbeck College, University of London; Henrietta Leyser, Medieval Historian and Fellow of St Peter’s College, Oxford; Michael Clanchy, Emeritus Professor of Medieval History at the Institute of Historical Research.

Exploring how our brains perceive data, starting with the intriguing discovery that a chimpanzee's hand can activate visual brain functions. The podcast also delves into how babies learn through touch, the chemical combination of smell and taste for flavor perception, and the complex interplay of the senses. It questions whether we truly perceive the world as others do and challenges the distinction between our sensory experiences.

Melvyn Bragg and guests discuss 'The Aeneid'. Out of the tragedy and destruction of the Trojan wars came a man heading West, his father on his back and his small son holding his hand. This isn't Odysseus, it's Aeneas and in that vision Virgil gives an image of the very first Romans of the Empire.Virgil's Aeneid was the great epic poem that formed a founding narrative of Rome. It made such an impact on its audience that it soon became a standard text in all schools and wiped away the myths that preceded it. It was written in Augustus' reign at the start of the Imperial era and has been called an apologia for Roman domination; it has also been called the greatest work of literature ever written.How much was Virgil's poem influenced by the extraordinary times in which it was written? How does it transcend the political pressures of Imperial patronage and what are the qualities that make it such a universal work?With Edith Hall, Leverhulme Professor of Greek Cultural History, Durham University; Philip Hardie, Corpus Christi Professor of Latin at the University of Oxford; Catharine Edwards, Senior Lecturer in Classics and Ancient History, Birkbeck College, University of London.
