Melvyn Bragg and his guests discuss the invention of radio. In the early 1860s the Scottish physicist James Clerk Maxwell derived four equations which together describe the behaviour of electricity and magnetism. They predicted the existence of a previously unknown phenomenon: electromagnetic waves. These waves were first observed in the early 1880s, and over the next two decades a succession of scientists and engineers built increasingly elaborate devices to produce and detect them. Eventually this gave birth to a new technology: radio. The Italian Guglielmo Marconi is commonly described as the father of radio - but many other figures were involved in its development, and it was not him but a Canadian, Reginald Fessenden, who first succeeded in transmitting speech over the airwaves.

Melvyn Bragg and his guests discuss the Romance of the Three Kingdoms, widely regarded as one of the greatest works of Chinese literature. Written 600 years ago, it is an historical novel that tells the story of a tumultuous period in Chinese history, the 2nd and 3rd centuries AD. Partly historical and partly legend, it recounts the fighting and scheming of the feudal lords and the three states which came to power as the Han Dynasty collapsed. The influence of Romance of the Three Kingdoms in East Asia has been likened to that of Homer in the West, and this warfare epic remains popular in China today.

Melvyn Bragg and his guests discuss Queen Zenobia, a famous military leader of the ancient world. Born in around 240 AD, Zenobia was Empress of the Palmyrene Empire in the Middle East. A highly educated, intelligent and militarily accomplished leader, she claimed descent from Dido and Cleopatra and spoke many languages, including Egyptian. Zenobia led a rebellion against the Roman Empire and conquered Egypt before being finally defeated by the Emperor Aurelian. Her story captured the imagination of many Renaissance writers, and has become the subject of numerous operas, poems and plays.

Melvyn Bragg and his guests discuss the work of the anthropologist Claude Lévi-Strauss. One of twentieth-century France's most celebrated intellectuals, Lévi-Strauss attempted to show in his work that thought processes were a feature universal to humans, whether they lived in tribal rainforest societies or in the rich intellectual life of Paris. During the 1930s he studied native Brazilian tribes in the Amazonian jungle, but for most of his long career he preferred the study to the field. He was the leading exponent of structuralism, a school of thought which was influential for decades, and was involved in a famous debate with his friend Jean-Paul Sartre, who resisted many of his ideas. His books about the nature of myth, human thought and kinship are now seen as some of the most important anthropological texts written in the twentieth century.

Melvyn Bragg and his guests discuss the Icelandic Sagas. First written down in the 13th century, the sagas tell the stories of the Norse settlers of Iceland, who began to arrive on the island in the late 9th century. They contain some of the richest and most extraordinary writing of the Middle Ages, and often depict events known to have happened in the early years of Icelandic history, although there is much debate as to how much of their content is factual and how much imaginative. Full of heroes, feuds and outlaws, with a smattering of ghosts and trolls, the sagas inspired later writers including Sir Walter Scott, William Morris and WH Auden.

Melvyn Bragg and his guests discuss the Essays of Michel de Montaigne. Born near Bordeaux in 1533, Montaigne retired from a life of public service aged 38 and began to write. He called these short works 'essais', or 'attempts'; they deal with an eclectic range of subjects, from the dauntingly weighty to the apparently trivial. Although he never considered himself a philosopher, he is often now seen as one of the most outstanding Sceptical thinkers of early modern Europe. His approachable style, intelligence and subtle thought have made him one of the most widely admired writers of the Renaissance.

Melvyn Bragg and his guests discuss the Amazons, a tribe of formidable female warriors first described in Greek literature. They appear in the Homeric epics and were described by Herodotus, and featured prominently in the decoration of Greek vases and public buildings. In later centuries, particularly in the Renaissance, the Amazons became a popular theme of literature and art. After the discovery of the New World, the largest river in South America was named the Amazon, since the warlike tribes inhabiting the river's margins reminded Spanish pioneers of the warriors of classical myth.

Melvyn Bragg and his guests discuss the life and work of Anton Chekhov. Born in 1860, Chekhov trained as a doctor and for most of his adult life divided his time between medicine and writing. Best known for plays including The Cherry Orchard and Three Sisters, he is also celebrated today as one of the greatest of short story writers. His works are often powerful character studies and chronicle the changing nature of Russian society in the late nineteenth century.

David Bradshaw, John Bowen and Ann Pasternak Slater join Melvyn Bragg to discuss Evelyn Waugh's comic novel Decline and Fall. Set partly in a substandard boys' public school, the novel is a vivid, often riotous portrait of 1920s Britain. Its themes, including modernity, religion and fashionable society, came to dominate Waugh's later fiction, but its savage wit and economy of style were entirely new. Published when Waugh was 24, the book was immediately celebrated for its vicious satire and biting humour.

Melvyn Bragg and his guests discuss Thomas Malory's "Le Morte Darthur", the epic tale of King Arthur and his knights of the Round Table. Sir Thomas Malory was a knight from Warwickshire, a respectable country gentleman and MP in the 1440s who later turned to a life of crime and spent various spells in prison. It was during Malory's final incarceration that he wrote "Le Morte Darthur", an epic work which was based primarily on French, but also some English, sources.

Malory died shortly after his release in 1470 and it was to be another fifteen years before "Le Morte Darthur" was published by William Caxton, to immediate popular acclaim. Although the book fell from favour in the seventeenth century, it was revived again in Victorian times and became an inspiration for the Pre-Raphaelite movement who were entranced by the chivalric and romantic world that Malory portrayed.

The Arthurian legend is one of the most enduring and popular in western literature and its characters - Sir Lancelot, Guinevere, Merlin and King Arthur himself, are as well-known today as they were then; and the book's themes - chivalry, betrayal, love and honour - remain as compelling.
