Sir Gawain and the Green Knight

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
