Melvyn Bragg and guests discuss Harriet Martineau who, from a non-conformist background in Norwich, became one of the best known writers in the C19th. She had a wide range of interests and used a new, sociological method to observe the world around her, from religion in Egypt to slavery in America and the rights of women everywhere. She popularised writing about economics for those outside the elite and, for her own popularity, was invited to the coronation of Queen Victoria, one of her readers.

Melvyn Bragg and guests discuss Giuseppe Garibaldi and the Italian Risorgimento. According to the historian AJP Taylor, Garibaldi was the only wholly admirable figure in modern history. Born in Nice in 1807, one of Garibaldi's aims in life was the unification of Italy and, in large part thanks to him, Italy was indeed united substantially in 1861 and entirely in 1870. With his distinctive red shirt and poncho, he was a hero of Romantic revolutionaries around the world. His fame was secured when, with a thousand soldiers, he invaded Sicily and toppled the monarchy in the Italian south. The Risorgimento was soon almost complete.This topic is the one chosen from over 750 different ideas suggested by listeners in October, for our yearly Listener Week.WithLucy Riall Professor of Comparative History of Europe at the European University Institute and Professor of History at Birkbeck, University of LondonEugenio Biagini Professor of Modern and Contemporary History at the University of CambridgeandDavid Laven Associate Professor of History at the University of NottinghamProducer: Simon Tillotson.

Melvyn Bragg and guests discuss the Baltic Crusades, the name given to a series of overlapping attempts to convert the pagans of North East Europe to Christianity at the point of the sword. From the 12th Century, Papal Bulls endorsed those who fought on the side of the Church, the best known now being the Teutonic Order which, thwarted in Jerusalem, founded a state on the edge of the Baltic, in Prussia. Some of the peoples in the region disappeared, either killed or assimilated, and the consequences for European history were profound.

Melvyn Bragg and guests discuss the ideas brought together under Justinian I, Byzantine emperor in the 6th century AD, which were rediscovered in Western Europe in the Middle Ages and became very influential in the development of laws in many European nations and elsewhere.WithCaroline Humfress Professor of Medieval History at the University of St AndrewsSimon Corcoran Lecturer in Ancient History at Newcastle Universityand Paul du Plessis Senior Lecturer in Civil law and European legal history at the School of Law, University of EdinburghProducer: Simon Tillotson.

This image: Joseph Mallord William Turner, The Fighting Temeraire, 1839 (c) The National Gallery, LondonMelvyn Bragg and guests discuss "The Fighting Temeraire", one of Turner's greatest works and the one he called his 'darling'. It shows one of the most famous ships of the age, a hero of Trafalgar, being towed up the Thames to the breakers' yard, sail giving way to steam. Turner displayed this masterpiece to a public which, at the time, was deep in celebration of the Temeraire era, with work on Nelson's Column underway, and it was an immediate success, with Thackeray calling the painting 'a national ode'.With Susan Foister Curator of Early Netherlandish, German and British Painting at the National GalleryDavid Blayney Brown Manton Curator of British Art 1790-1850 at Tate Britainand James Davey Curator of Naval History at the National Maritime MuseumProducer: Simon Tillotson.

"He who saw the Deep" are the first words of the standard version of The Epic of Gilgamesh, the subject of this discussion between Melvyn Bragg and his guests. Gilgamesh is often said to be the oldest surviving great work of literature, with origins in the third millennium BC, and it passed through thousands of years on cuneiform tablets. Unlike epics of Greece and Rome, the intact story of Gilgamesh became lost to later generations until tablets were discovered by Hormuzd Rassam in 1853 near Mosul and later translated. Since then, many more tablets have been found and much of the text has been reassembled to convey the story of Gilgamesh, king of Uruk the sheepfold, and Enkidu who the gods created to stop Gilgamesh oppressing his people. Together they fight Humbaba, monstrous guardian of the Cedar Forest, and kill the Bull of Heaven, for which the gods make Enkidu mortally ill. Gilgamesh goes on a long journey as he tries unsuccessfully to learn how to live forever, learning about the Great Deluge on the way, but his remarkable building works guarantee that his fame will last long after his death.With Andrew George Professor of Babylonian at SOAS, University of LondonFrances Reynolds Shillito Fellow in Assyriology at the Oriental Institute, University of Oxford and Fellow of St Benet's HallandMartin Worthington Lecturer in Assyriology at the University of CambridgeProducer: Simon Tillotson.

The scientist John Dalton was born in North England in 1766. Although he came from a relatively poor Quaker family, he managed to become one of the most celebrated scientists of his age. Through his work, he helped to establish Manchester as a place where not only products were made but ideas were born. His reputation during his lifetime was so high that unusually a statue was erected to him before he died. Among his interests were meteorology, gasses and colour blindness. However, he is most remembered today for his pioneering thinking in the field of atomic theory.

Melvyn Bragg and guests discuss the changes in the intellectual world of Western Europe in the 12th Century, and their origins. This was a time of Crusades, the formation of states, the start of Gothic architecture, a reconnection with Roman and Greek learning and their Arabic development and the start of the European universities, and has become known as The 12th Century Renaissance.The image above is part of Notre-Dame de la Belle-Verrière, Chartres Cathedral, from 1180.WithLaura Ashe Associate Professor of English at Worcester College, University of Oxford Elisabeth van Houts Honorary Professor of European Medieval History at the University of Cambridge and Giles Gasper Reader in Medieval History at Durham UniversityProducer: Simon Tillotson.

Melvyn Bragg and guests discuss The Bronze Age Collapse, the name given by many historians to what appears to have been a sudden, uncontrolled destruction of dominant civilizations around 1200 BC in the Aegean, Eastern Mediterranean and Anatolia. Among other areas, there were great changes in Minoan Crete, Egypt, the Hittite Empire, Mycenaean Greece and Syria. The reasons for the changes, and the extent of those changes, are open to debate and include droughts, rebellions, the breakdown of trade as copper became less desirable, earthquakes, invasions, volcanoes and the mysterious Sea Peoples.

Melvyn Bragg and guests discuss the English mystic Margery Kempe (1373-1438) whose extraordinary life is recorded in a book she dictated, The Book of Margery Kempe. She went on pilgrimage to Jerusalem, to Rome and Santiago de Compostela, purchasing indulgences on her way, met with the anchoress Julian of Norwich and is honoured by the Church of England each 9th November. She sometimes doubted the authenticity of her mystical conversations with God, as did the authorities who saw her devotional sobbing, wailing and convulsions as a sign of insanity and dissoluteness. Her Book was lost for centuries, before emerging in a private library in 1934.The image (above), of an unknown woman, comes from a pew at Margery Kempe's parish church, St Margaret's, Kings Lynn and dates from c1375.WithMiri Rubin Professor of Medieval and Early Modern History at Queen Mary, University of LondonKatherine Lewis Senior Lecturer in History at the University of HuddersfieldAndAnthony Bale Professor of Medieval Studies at Birkbeck University of LondonProducer: Simon Tillotson.
