Melvyn Bragg and guests discuss Katsushika Hokusai (1760-1849), the Japanese artist whose views of Mt Fuji such as The Great Wave off Kanagawa (pictured) are some of the most iconic in world art. He worked as Japan was slowly moving towards greater contact with the outside world, trading with China and allowing two Dutch ships to dock each year. From these ships he picked up new synthetic colours and illustrations with Western compositions, which he incorporated in his traditional wood block prints. The quality of his images helped drive demand for prints among the highly literate Japanese public, particularly those required to travel to Edo under feudal obligations and who wanted to collect all his prints. As well as the quality of his work, Hokusai's success stems partly from his long life and career. He completed some of his most memorable works in his 70s and 80s and claimed he would not reach his best until he was 110.With Angus Lockyer Lecturer in Japanese History at SOAS University of LondonRosina Buckland Senior Curator of Japanese Collections at the National Museum of ScotlandAnd Ellis Tinios Honorary Lecturer in the School of History, University of LeedsProducer: Simon Tillotson.

A discussion about the historic Battle of Salamis, where the outnumbered Greeks emerged victorious, impacting Greek culture. Persians' motivations for invading Greece and the aftermath of their defeat explored. The diversity of the Persian army and their perspectives on the battle examined. Athens' influence on Greek culture and the factors that influenced the outcome of the battle analyzed.

Exploring the Paleocene-Eocene Thermal Maximum, a period of rapid climate change marked by increased temperatures and extinctions. The rise in temperature was attributed to an increase in carbon dioxide and methane, possibly released from frozen crystals in the sea bed. The podcast discusses the evidence for this event, including changes in fossil plants and animals, and the process of drilling into deep sea sediments to uncover valuable insights. It also explores the significance of the Paleocene-Eocene Thermal Maximum for understanding current climate change and the potential threats of methane hydrates.

Melvyn Bragg and guests discuss Elizabeth Gaskell's novel North and South, published in 1855 after serialisation in Dickens' Household Words magazine. It is the story of Margaret Hale, who was raised in the South in the New Forest and London's Harley Street, and then moves North to a smokey mill town, Milton, in Darkshire. As well as Margaret's emotional life and her growing sense of independence, the novel explores the new ways of living thrown up by industrialisation, and the relationships between 'masters and men'. Many of Margaret Hale's experiences echo Gaskell's own life, as she was born in Chelsea and later moved to Manchester, and the novel has become valued for its insights into social conflicts and the changing world in which Gaskell lived.With Sally Shuttleworth Professor of English Literature at the University of OxfordDinah Birch Pro-vice Chancellor for Research and Professor of English Literature at the University of LiverpoolAndJenny Uglow Biographer of Elizabeth GaskellProducer: Simon Tillotson.

This podcast discusses the Kuiper Belt, a vast region of icy objects on the fringes of our solar system. They talk about its formation, the reclassification of Pluto, the significance of temperature and composition, exploring the scattered disk, the hypothetical ouch cloud, and the ongoing search for the elusive Planet X.

Melvyn Bragg and guests discuss Seneca the Younger, who was one of the first great writers to live his entire life in the world of the new Roman empire, after the fall of the Republic. He was a Stoic philosopher, he wrote blood-soaked tragedies, he was an orator, and he navigated his way through the reigns of Caligula, Claudius and Nero, sometimes exercising power at the highest level and at others spending years in exile. Agrippina the Younger was the one who called for him to tutor Nero, and it is thought Seneca helped curb some of Nero's excesses. He was later revered within the Christian church, partly for what he did and partly for what he was said to have done in forged letters to St Paul. His tragedies, with their ghosts and high body count, influenced Shakespeare's Titus Andronicus and Hamlet, and Kyd's Spanish Tragedy. The image above is the so-called bust of Seneca, a detail from Four Philosophers by Peter Paul Rubens.WithMary Beard Professor of Classics at the University of CambridgeCatharine Edwards Professor of Classics and Ancient History at Birkbeck, University of LondonandAlessandro Schiesaro Professor of Classics at the University of ManchesterProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the flourishing of maths in the early Islamic world, as thinkers from across the region developed ideas in places such as Baghdad's House of Wisdom. Among them were the Persians Omar Khayyam, who worked on equations, and Al-Khwarizmi, latinised as Algoritmi and pictured above, who is credited as one of the fathers of algebra, and the Jewish scholar Al-Samawal, who converted to Islam and worked on mathematical induction. As well as the new ideas, there were many advances drawing on Indian, Babylonian and Greek work and, thanks to the recording or reworking by mathematicians in the Islamic world, that broad range of earlier maths was passed on to western Europe for further study.With Colva Roney-Dougal Reader in Pure Mathematics at the University of St AndrewsPeter Pormann Professor of Classics & Graeco-Arabic Studies at the University of ManchesterAndJim Al-Khalili Professor of Physics at the University of SurreyProducer: Simon Tillotson.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the Northamptonshire poet John Clare who, according to one of Melvyn's guests Jonathan Bate, was 'the greatest labouring-class poet that England has ever produced'. Clare worked in a tavern, as a gardener and as a farm labourer in the early 19th century and achieved his first literary success with Poems Descriptive of Rural Life and Scenery. He was praised for his descriptions of rural England and his childhood there, and his reaction to the changes he saw in the Agricultural Revolution with its enclosures, displacement and altered, disrupted landscape. Despite poor mental health and, from middle age onwards, many years in asylums, John Clare continued to write and he is now seen as one of the great poets of his age.With Sir Jonathan Bate Provost of Worcester College, University of OxfordMina Gorji Senior Lecturer in the English Faculty and fellow of Pembroke College, Cambridgeand Simon Kövesi Professor of English Literature at Oxford Brookes UniversityProducer: Simon Tillotson.

In a programme first broadcast in 2017, Melvyn Bragg and guests discuss the political philosophy of Hannah Arendt. She developed many of her ideas in response to the rise of totalitarianism in the C20th, partly informed by her own experience as a Jew in Nazi Germany before her escape to France and then America. She wanted to understand how politics had taken such a disastrous turn and, drawing on ideas of Greek philosophers as well as her peers, what might be done to create a better political life. Often unsettling, she wrote of 'the banality of evil' when covering the trial of Eichmann, one of the organisers of the Holocaust.WithLyndsey Stonebridge Professor of Modern Literature and History at the University of East AngliaFrisbee Sheffield Lecturer in Philosophy at Girton College, University of CambridgeandRobert Eaglestone Professor of Contemporary Literature and Thought at Royal Holloway, University LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the relationship between parasites and hosts, where one species lives on or in another to the benefit of the parasite but at a cost to the host, potentially leading to disease or death of the host. Typical examples are mistletoe and trees, hookworms and vertebrates, cuckoos and other birds. In many cases the parasite species do so well in or on a particular host that they reproduce much faster and can adapt to changes more efficiently, and it is thought that almost half of all animal species have a parasitic stage in their lifetime. What techniques do hosts have to counter the parasites, and what impact do parasites have on the evolution of their hosts?
