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

Maria Theresa, Queen of Austria, transformed the country into a formidable power. She faced challenges from neighboring countries but implemented political reforms, formed alliances, and protected the religious interests of her Catholic subjects. Her strategic marriages for her children showcased her determination to control every aspect of their lives. The marriage of Maria Antoinette to the Dauphin of France was a diplomatic triumph. Maria Theresa's legacy includes her intrusive and meddling nature as a ruler, unintended consequences of her interventions, and her implementation of enlightened policies.

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

Exploring the creation and purpose of Stone Age cave art, including the possibility of Neanderthals being capable of artistic expression. Examining the techniques used in cave art and the significance of animals in these works. Delving into the symbolism and challenges of studying cave art and its connection to the underworld.

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
