Melvyn Bragg and guests discuss St Augustine of Hippo's account of his conversion to Christianity and his life up to that point. Written c397AD, it has many elements of autobiography with his scrutiny of his earlier life, his long relationship with a concubine, his theft of pears as a child, his work as an orator and his embrace of other philosophies and Manichaeism. Significantly for the development of Christianity, he explores the idea of original sin in the context of his own experience. The work is often seen as an argument for his Roman Catholicism, a less powerful force where he was living in North Africa where another form of Christianity was dominant, Donatism. While Augustine retells many episodes from his own life, the greater strength of his Confessions has come to be seen as his examination of his own emotional development, and the growth of his soul.WithKate Cooper Professor of History at the University of London and Head of History at Royal HollowayMorwenna Ludlow Professor of Christian History and Theology at the University of Exeterand Martin Palmer Visiting Professor in Religion, History and Nature at the University of WinchesterProducer: Simon Tillotson.

Discussion on the forced eviction of Highlanders and Islanders in the 18th and 19th centuries, the impact of the Napoleonic Wars, resistance and protests during the Clearances, the forgotten experience of lowland clearances, and the ongoing legacy on Scottish culture and national life.

Melvyn Bragg and guests discuss the ideas attributed to Sun Tzu (544-496BC, according to tradition), a legendary figure from the beginning of the Iron Age in China, around the time of Confucius. He may have been the historical figure Sun Wu, a military adviser at the court of King Helu of Wu (who reigned between about 514 and 496 BC), one of the kings in power in the Warring States period of Chinese history (6th - 5th century BC). Sun Tzu was credited as the author of The Art of War, a work on military strategy that soon became influential in China and then Japan both for its guidance on conducting and avoiding war and for its approach to strategy generally. After The Art of War was translated into European languages in C18th, its influence spread to military academies around the world.The image above is of a terracotta warrior from the tomb of Qin Shi Huang, the first Emperor, who unified China after the Warring States period.With Hilde De Weerdt Professor of Chinese History at Leiden UniversityTim Barrett Professor Emeritus of East Asian History at SOAS, University of LondonAndImre Galambos Reader in Chinese Studies at the University of CambridgeProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the pioneering scientist Rosalind Franklin (1920 - 1958). During her distinguished career, Franklin carried out ground-breaking research into coal and viruses but she is perhaps best remembered for her investigations in the field of DNA. In 1952 her research generated a famous image that became known as Photograph 51. When the Cambridge scientists Francis Crick and James Watson saw this image, it enabled them the following year to work out that DNA has a double-helix structure, one of the most important discoveries of modern science. Watson, Crick and Franklin's colleague Maurice Wilkins received a Nobel Prize in 1962 for this achievement but Franklin did not and today many people believe that Franklin has not received enough recognition for her work.

Melvyn Bragg and guests discuss fungi. These organisms are not plants or animals but a kingdom of their own. Millions of species of fungi live on the Earth and they play a crucial role in ecosystems, enabling plants to obtain nutrients and causing material to decay. Without fungi, life as we know it simply would not exist. They are also a significant part of our daily life, making possible the production of bread, wine and certain antibiotics. Although fungi brought about the colonisation of the planet by plants about 450 million years ago, some species can kill humans and devastate trees.

In a programme first broadcast in 2018, Melvyn Bragg and guests discuss the life and ideas of Frederick Douglass, who was born into slavery in Maryland in 1818 and, once he had escaped, became one of that century's most prominent abolitionists. He was such a good orator, his opponents doubted his story, but he told it in grim detail in 1845 in his book 'Narrative of the Life of Frederick Douglass, an American Slave.' He went on to address huge audiences in Great Britain and Ireland and there some of his supporters paid off his owner, so Douglass could be free in law and not fear recapture. After the Civil War and the abolition of slavery, he campaigned for equal rights for African-Americans, arguing against those such as Lincoln who had wanted freed slaves to leave America and found a colony elsewhere. "We were born here," he said, "and here we will remain."WithCeleste-Marie Bernier Professor of Black Studies in the English Department at the University of EdinburghKaren Salt Assistant Professor in Transnational American Studies at the University of NottinghamAndNicholas Guyatt Reader in North American History at the University of CambridgeProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the ideas developed by Marcus Tullius Cicero (106-43BC) to support and reinvigorate the Roman Republic when, as it transpired, it was in its final years, threatened by civil wars, the rule of Julius Caesar and the triumvirates that followed. As Consul he had suppressed a revolt by Catiline, putting the conspirators to death summarily as he believed the Republic was in danger and that this danger trumped the right to a fair trial, a decision that rebounded on him. While in exile he began works on duty, laws, the orator and the republic. Although left out of the conspiracy to kill Caesar, he later defended that murder in the interests of the Republic, only to be murdered himself soon after.With Melissa Lane The Class of 1943 Professor of Politics at Princeton University and 2018 Carlyle Lecturer at the University of OxfordCatherine Steel Professor of Classics at the University of GlasgowAndValentina Arena Reader in Roman History at University College LondonProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the work, ideas and life of the Russian poet whose work was celebrated in C20th both for its quality and for what it represented, written under censorship in the Stalin years. Her best known poem, Requiem, was written after her son was imprisoned partly as a threat to her and, to avoid punishment for creating it, she passed it on to her supporters to be memorised, line by line, rather than written down. She was a problem for the authorities and became significant internationally, as her work came to symbolise resistance to political tyranny and the preservation of pre-Revolutionary liberal values in the Soviet era.The image above is based on 'Portrait of Anna Akhmatova' by N.I.

Melvyn Bragg and guests discuss the event of which Voltaire, two hundred years later, said 'nothing was more well known'. In 1565, Suleiman the Magnificent, the Ottoman leader, sent a great fleet west to lay siege to Malta and capture it for his empire. Victory would mean control of trade across the Mediterranean and a base for attacks on Spain, Sicily and southern Italy, even Rome. It would also mean elimination of Malta's defenders, the Knights Hospitaller, driven by the Ottomans from their base in Rhodes in 1522 and whose raids on his shipping had long been a thorn in his side. News of the Great Siege of Malta spread fear throughout Europe, though that turned to elation when, after four months of horrific fighting, the Ottomans withdrew, undermined by infighting between their leaders and the death of the highly-valued admiral, Dragut. The Knights Hospitaller had shown that Suleiman's forces could be contained, and their own order was reinvigorated. The image above is the Death of Dragut at the Siege of Malta (1867), after a painting by Giuseppe Cali. Dragut (1485 – 1565) was an Ottoman Admiral and privateer, known as The Drawn Sword of Islam and as one of the finest generals of the time.With Helen Nicholson Professor of Medieval History at Cardiff UniversityDiarmaid MacCulloch Professor of the History of the Church at the University of OxfordandKate Fleet Director of the Skilliter Centre for Ottoman Studies and Fellow of Newnham College, CambridgeProducer: Simon Tillotson.
