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.

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.

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.

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.

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.

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.

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.

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.
