Echolocation

Melvyn Bragg and guests discuss how some bats, dolphins and other animals emit sounds at high frequencies to explore their environments, rather than sight. This was such an unlikely possibility, to natural historians from C18th onwards, that discoveries were met with disbelief even into the C20th; it was assumed that bats found their way in the dark by touch. Not all bats use echolocation, but those that do have a range of frequencies for different purposes and techniques for preventing themselves becoming deafened by their own sounds. Some prey have evolved ways of detecting when bats are emitting high frequencies in their direction, and some fish have adapted to detect the sounds dolphins use to find them.

Montesquieu

Melvyn Bragg and guests discuss the ideas of Charles-Louis de Secondat, Baron de La Brède et de Montesquieu (1689-1755) whose works on liberty, monarchism, despotism, republicanism and the separation of powers were devoured by intellectuals across Europe and New England in the eighteenth century, transforming political philosophy and influencing the American Constitution. He argued that an individual's liberty needed protection from the arm of power, checking that by another power; where judicial, executive and legislative power were concentrated in the hands of one figure, there could be no personal liberty. With Richard Bourke Professor in the History of Political Thought at Queen Mary, University of LondonRachel Hammersley Senior Lecturer in Intellectual History at Newcastle UniversityAndRichard Whatmore Professor of Modern History at the University of St Andrews and Director of the St Andrews Institute of Intellectual HistoryProducer: Simon Tillotson.

Persepolis

Melvyn Bragg and guests discuss the role of the great 'City of the Persians' founded by Darius I as the ceremonial capital of the Achaemenid Empire that stretched from the Indus Valley to Egypt and the coast of the Black Sea. It was known as the richest city under the sun and was a centre at which the Empire's subject peoples paid tribute to a succession of Achaemenid leaders, until the arrival of Alexander III of Macedon who destroyed it by fire supposedly in revenge for the burning of the Acropolis in Athens.The image above is a detail from a relief at the Apadana, the huge audience hall, and shows a lion attacking a bull.With Lloyd Llewellyn-Jones Professor of Ancient History at Cardiff UniversityVesta Sarkhosh Curtis Curator of Middle Eastern Coins at the British MuseumAndLindsay Allen Lecturer in Greek and Near Eastern History at King's College LondonProducer: Simon Tillotson.

Henrik Ibsen

Melvyn Bragg and guests discuss the great Norwegian playwright and poet, best known for his middle class tragedies such as The Wild Duck, Hedda Gabler, A Doll's House and An Enemy of the People. These are set in a world where the middle class is dominant and explore the qualities of that life, its weaknesses and boundaries and the ways in which it takes away freedoms. It is the women who fare the worst in this society, something Ibsen explored in A Doll's House among others, a play that created a sensation with audiences shocked to watch a woman break free of her bourgeois family life to find her destiny. He explored dark secrets such as incest and, in Ghosts, hereditary syphilis, which attracted the censors. He gave actresses parts they had rarely had before, and audiences plays that, after Shakespeare, became the most performed in the world.With Tore Rem Professor of English Literature at the University of OsloKirsten Shepherd-Barr Professor of English and Theatre Studies and Tutorial Fellow, St Catherine's College at the University of OxfordAnd Dinah Birch Professor of English Literature and Pro-Vice Chancellor for Cultural Engagement at the University of LiverpoolProducer: Simon Tillotson.

Margaret of Anjou

Melvyn Bragg and guests discuss one of the most remarkable queens of the Middle Ages who took control when her husband, Henry VI, was incapable. Margaret of Anjou (1430-1482) wanted Henry to stay in power for the sake of their son, the heir to the throne, and her refusal to back down was seen by her enemies as a cause of the great dynastic struggle of the Wars of the Roses.

The Emancipation of the Serfs

Melvyn Bragg and guests discuss the 1861 declaration by Tsar Alexander II that serfs were now legally free of their landlords. Until then, over a third of Russians were tied to the land on which they lived and worked and in practice there was little to distinguish their condition from slavery. Russia had lost the Crimean War in 1855 and there had been hundreds of uprisings, prompting the Tsar to tell the nobles, "The existing condition of owning souls cannot remain unchanged. It is better to begin to destroy serfdom from above than to wait until that time when it begins to destroy itself from below." Reform was constrained by the Tsar's wish to keep the nobles on side and, for the serfs, tied by debt and law to the little land they were then allotted, the benefits were hard to see. With Sarah Hudspith Associate Professor in Russian at the University of LeedsSimon Dixon The Sir Bernard Pares Professor of Russian History at UCLAndShane O'Rourke Senior Lecturer in History at the University of YorkProducer: Simon Tillotson.

The Almoravid Empire

Melvyn Bragg and guests discuss the Berber people who grew to dominate the western Maghreb, founded Marrakesh and took control of Al-Andalus. They were desert people, wearing veils over their faces to keep out the sand, and they wanted a simpler form of Islam. They called themselves the Murabitun, the people who gathered together to fight the holy war, and they were tough fighters; the Spanish knight El Cid fought them and lost, and the legend that built around him said the Almoravids were terrible and had to be resisted. They kept back the Christians of northern Spain, so helping extend Muslim rule in the Iberian Peninsula, before they themselves were destroyed and replaced by their rivals, the Almohads, from the Atlas Mountains.The image above shows the interior of the cupola, Almoravid Koubba, Marrakesh (C11th)With Amira K Bennison Professor in the History and Culture of the Maghreb at the University of CambridgeNicola Clarke Lecturer in the History of the Islamic World at Newcastle UniversityAnd Hugh Kennedy Professor of Arabic at SOAS, University of LondonProducer: Simon Tillotson.

Middlemarch

Melvyn Bragg and guests discuss what Virginia Woolf called 'one of the few English novels written for grown-up people'. It was written by George Eliot, the pen name of Mary Anne Evans (1819-80), published in 8 parts in 1871-72, and was originally two separate stories which became woven together. One, 'Middlemarch', focused on a doctor, Tertius Lydgate and the other, 'Miss Brooke', on Dorothea Brooke who became the central figure in the finished work. The events are set in a small town in the Midlands, surrounded by farmland, leading up to the Reform Act 1832, and the novel explores the potential to change in matters of religion, social status, marriage and politics, and is particularly concerned with the opportunities available to women to lead fulfilling lives.
