Melvyn Bragg and guests discuss solar eclipses, some of life’s most extraordinary moments, when day becomes night and the stars come out before day returns either all too soon or not soon enough, depending on what you understand to be happening. In ancient China, for example, there was a story that a dragon was eating the sun and it had to be scared away by banging pots and pans if the sun were to return. Total lunar eclipses are more frequent and last longer, with a blood moon coloured red like a sunrise or sunset. Both events have created the chance for scientists to learn something remarkable, from the speed of light, to the width of the Atlantic, to the roundness of Earth, to discovering helium and proving Einstein’s Theory of General Relativity. With Carolin Crawford Public Astronomer based at the Institute of Astronomy, University of Cambridge and a fellow of Emmanuel College Frank Close Emeritus Professor of Physics at the University of Oxford And Lucie Green Professor of Physics and a Royal Society University Research Fellow at Mullard Space Science Laboratory at University College London Producers: Simon Tillotson and Julia Johnson

Melvyn Bragg and guests discuss Chairman Mao and the revolt he led within his own party from 1966, setting communists against each other, to renew the revolution that he feared had become too bourgeois and to remove his enemies and rivals. Universities closed and the students formed Red Guard factions to attack the 'four olds' - old ideas, culture, habits and customs - and they also turned on each other, with mass violence on the streets and hundreds of thousands of deaths. Over a billion copies of Chairman Mao’s Little Red Book were printed to support his cult of personality, before Mao himself died in 1976 and the revolution came to an end. The image above is of Red Guards, holding The Little Red Book, cheering Mao during a meeting to celebrate the Great Proletarian Cultural Revolution at Tiananmen Square, Beijing, August 1966 With Rana Mitter Professor of the History and Politics of Modern China and Fellow of St Cross College, University of Oxford Sun Peidong Visiting Professor at the Center for International Studies at Sciences Po, Paris And Julia Lovell Professor in Modern Chinese History and Literature at Birkbeck, University of London Produced by Simon Tillotson and Julia Johnson

Melvyn Bragg and guests discuss John Wesley (1703 - 1791) and the movement he was to lead and inspire. As a student, he was mocked for approaching religion too methodically and this jibe gave a name to the movement: Methodism. Wesley took his ideas out across Britain wherever there was an appetite for Christian revival, preaching in the open, especially the new industrial areas. Others spread Methodism too, such as George Whitefield, and the sheer energy of the movement led to splits within it, but it soon became a major force. With Stephen Plant Dean and Runcie Fellow at Trinity Hall at the University of Cambridge Eryn White Reader in Early Modern History at Aberystwyth University And William Gibson Professor of Ecclesiastical History at Oxford Brookes University and Director of the Oxford Centre for Methodism and Church History Produced by Simon Tillotson and Julia Johnson

Melvyn Bragg and guests discuss the Portuguese poet Pessoa (1888-1935) who was largely unknown in his lifetime but who, in 1994, Harold Bloom included in his list of the 26 most significant western writers since the Middle Ages. Pessoa wrote in his own name but mainly in the names of characters he created, each with a distinctive voice and biography, which he called heteronyms rather than pseudonyms, notably Ricardo Reis, Alberto Caeiro, Álvaro de Campos and one who was closer to Pessoa's own identity, Bernardo Soares. Most of Pessoa's works were unpublished at his death, discovered in a trunk; as more and more was printed and translated, his fame and status grew. With Cláudia Pazos-Alonso Professor of Portuguese and Gender Studies and Senior Research Fellow at Wadham College, University of Oxford Juliet Perkins Visiting Senior Research Fellow in Portuguese Studies at King’s College London And Paulo de Medeiros Professor of English and Comparative Literary Studies at the University of Warwick Producer: Simon Tillotson

Melvyn Bragg and guests discuss the notorious events off Jamaica in 1781 and their background. The British slave ship Zong, having sailed across the Atlantic towards Jamaica, threw 132 enslaved Africans from its human cargo into the sea to drown. Even for a slave ship, the Zong was overcrowded; those murdered were worth more to the ship dead than alive. The crew said there was not enough drinking water to go round and they had no choice, which meant they could claim for the deaths on insurance. The main reason we know of this atrocity now is that the owners took their claim to court in London, and the insurers were at first told to pay up as if the dead slaves were any other lost goods, not people. Abolitionists in Britain were scandalised: if courts treated mass murder in the slave trade as just another business transaction and not a moral wrong, the souls of the nation would be damned. But nobody was ever prosecuted. The image above is of sailors throwing slaves overboard, from Torrey's 'American Slave Trade', 1822 With Vincent Brown Charles Warren Professor of American History and Professor of African and African American Studies at Harvard University Bronwen Everill Class of 1973 Lecturer in History and Fellow at Gonville & Caius College, University of Cambridge And Jake Subryan Richards Assistant Professor of History at the London School of Economics Studio production: Hannah Sander Producer: Simon Tillotson

Melvyn Bragg and guests discuss the great German artist Albrecht Dürer (1471-1528) who achieved fame throughout Europe for the power of his images. These range from his woodcut of a rhinoceros, to his watercolour of a young hare, to his drawing of praying hands and his stunning self-portraits such as that above (albeit here in a later monochrome reproduction) with his distinctive A D monogram. He was expected to follow his father and become a goldsmith, but found his own way to be a great artist, taking public commissions that built his reputation but did not pay, while creating a market for his prints, and he captured the timeless and the new in a world of great change.

The philosopher Mary Astell (1666 – 1731) has been described as “the first English feminist”. Born in Newcastle in relatively poor circumstances in the aftermath of the upheaval of the English Civil War and the restoration of the monarchy, she moved to London as a young woman and became part of an extraordinary circle of intellectual and aristocratic women. In her pioneering publications, she argued that women’s education should be expanded, that men and women’s minds were the same and that no woman should be forced to marry against her will. Perhaps her most famous quotation is: “If all Men are born Free, why are all Women born Slaves?” Today, she is one of just a handful of female philosophers to be featured in the multi-volume Cambridge History of Political Thought. The image above is from Astell's "Reflections upon Marriage", 3rd edition, 1706, held by the British Library (Shelfmark 8415.bb.27) With: Hannah Dawson Senior Lecturer in the History of Ideas at King’s College London Mark Goldie Professor Emeritus of Intellectual History at the University of Cambridge Teresa Bejan Associate Professor of Political Theory at Oriel College, University of Oxford Producer: Simon Tillotson

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.

Melvyn Bragg and guests discuss Maria Theresa (1717-1780) who inherited the Austrian throne in 1740 at the age of 23. Her neighbours circled like wolves and, within two months, Frederick the Great had seized one of her most prized lands, Silesia, exploiting her vulnerability. Yet over the next forty years through political reforms, alliances and marriages, she built Austria up into a formidable power, and she would do whatever it took to save the souls of her Catholic subjects, with a rigidity and intolerance that Joseph II, her son and heir, could not wait to challenge. With Catriona Seth Marshal Foch Professor of French Literature at the University of Oxford Martyn Rady Professor of Central European History at University College London And Thomas Biskup Lecturer in Early Modern History at the University of Hull Producer: Simon Tillotson

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.

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.

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.

Melvyn Bragg and guests discuss ideas about the Stone Age people who created the extraordinary images found in caves around the world, from hand outlines to abstract symbols to the multicoloured paintings of prey animals at Chauvet and, as shown above, at Lascaux. In the 19th Century, it was assumed that only humans could have made these, as Neanderthals would have lacked the skills or imagination, but new tests suggest otherwise. How were the images created, were they meant to be for private viewing or public spaces, and what might their purposes have been? And, if Neanderthals were capable of creative work, in what ways were they different from humans? What might it have been like to experience the paintings, so far from natural light? With Alistair Pike Professor of Archaeological Sciences at the University of Southampton Chantal Conneller Senior Lecturer in Early Pre-History at Newcastle University And Paul Pettitt Professor of Palaeolithic Archaeology at Durham University Producer: Simon Tillotson

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.

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.

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.

Melvyn Bragg and guests discuss the origins of horses, from their dog sized ancestors to their proliferation in the New World until hunted to extinction, their domestication in Asia and their development since. The genetics of the modern horse are the most studied of any animal, after humans, yet it is still uncertain why they only have one toe on each foot when their wider family had more, or whether speed or stamina has been more important in their evolution. What is clear, though, is that when humans first chose to ride horses, as well as eat them, the future of both species changed immeasurably.

Melvyn Bragg and guests discuss the debate in Valladolid, Spain in 1550, over Spanish rights to enslave the native peoples in the newly conquered lands. Bartolomé de Las Casas (pictured above), the Bishop of Chiapas, Mexico, was trying to end the encomienda system in which those who now owned the land could also take the people in forced labour. Juan Gines Sepulveda, a philosopher, argued for the colonists' property rights over people, asserting that some native Americans were 'natural slaves' as defined by Aristotle. Valladolid became seen as the first open attempt by European colonists to discuss the ethics of slavery, and Las Casas became known as 'Saviour of the Indians' and an advocate for human rights, although for some time he argued that African slaves be imported to do the work in place of the native people, before repenting.

Melvyn Bragg and guests discuss the great Roman military disaster of 9 AD when Germanic tribes under Arminius ambushed and destroyed three legions under Varus. According to Suetonius, emperor Augustus hit his head against the wall when he heard the news, calling on Varus to give him back his legions. The defeat ended Roman expansion east of the Rhine. Victory changed the development of the Germanic peoples, both in the centuries that followed and in the nineteenth century when Arminius, by then known as Herman, became a rallying point for German nationalism.
