China, Iran, Afghanistan, Syria, Uzbekistan and India: if you went to any of these places a thousand years ago, you would find goods and produce from the others. But how did they get there and why? This week’s Forum explores the ancient pattern of trading networks which criss-crossed the plains, deserts and mountains of China, Central Asia and points further West, and which encouraged not just the exchange of commodities such as silk, paper and horses but ideas and people too. Bridget Kendall talks to Valerie Hansen, professor of history at Yale University who has a particular interest in trade and exchanges across Eurasia; historian Dr. Susan Whitfield, former curator of the Central Asian collections at the British Library in London; and Tamara Chin, professor of comparative literature at Brown University whose work focuses on ancient China.(Photo: A man rides a horse at Band-e-Amir lake, central Afghanistan, on a former Silk Route that once linked China with Central Asia and beyond.

Bertha von Suttner’s path to becoming a leading 19th-century pacifist and the first woman to win the Nobel Peace Prize was far from straightforward. The product of the aristocratic and militaristic world of 19th century Bohemia, as a young woman von Suttner eloped to the Caucasus and turned her hand to writing for a living. On her return to Europe she published an acclaimed anti-war novel, Lay Down Your Arms, a work that marked the start of her quest for disarmament. Her long friendship with Alfred Nobel finally bore fruit in the Swedish industrialist’s last will which included the Peace Prize.Bridget Kendall is joined by Dr. Barbara Burns, Reader in German at Glasgow University, and the editor of a new English edition of Lay Down Your Arms; Dr. Peter van den Dungen, former Lecturer in Peace Studies at the University of Bradford and until recently General Coordinator of the International Network of Museums for Peace; and musician Stefan Frankenberger, the author of an audio book called The Unknown Soldier, In memory of Bertha von Suttner.

Born more than six hundred years ago, Joan of Arc is regarded as a French national heroine – a peasant girl who, inspired by saintly visions, battled to break the Siege of Orléans and see Charles VII finally crowned King of France in a grand cathedral. But in 1431, she was burned at the stake.Bridget Kendall and guests discuss the life and death of this medieval teenage celebrity who helped to shape the course of the Hundred Years War with England. They also reflect on her status as an enduring symbol in popular culture through the ages, including on the stage and the big screen. Bridget is joined by film scholar Robin Blaetz, and historians Juliet Barker, Xavier Helary and Daniel Hobbins.Photo: Joan of Arc: Painting by J D Ingres in the Louvre. (Hulton Archive/Getty Images)

With its Hanging Gardens and huge walls, Babylon was celebrated as one of the Seven Wonders of the ancient world; to the Israelites enslaved there under Nebuchadnezzar, it was a lasting emblem of oppression and depravity, where they wept as they remembered Zion. It is only in the last two hundred years that Babylon's fuller history has been unearthed, both the remains of its buildings and a huge number of clay tablets covered in writing, revealing a complex world that created epic stories, powerful people and an understanding of science and the stars, and it was their 60 based numbering system that led to our 60 seconds in a minute and 60 minutes in an hour. It has been called a cradle of civilisation.Bridget Kendall explores the reputation of Babylon and its contribution to the world with four experts: Frances Reynolds, Shillito Fellow in Assyriology at the Oriental Institute, University of Oxford; Grant Frame, Professor of Assyriology at the University of Pennsylvania and Curator of the Babylonian Section of Penn Museum; Daniel Schwemer, Chair of Ancient Oriental Studies at the University of Würzburg; and Jaafar Jotheri, Assistant Professor in Geoarchaeology at the University of Al-Qadisiyah, Iraq.(Image: Detail of the Ishtar gate, Babylon.

Aesop, with his tales of tortoises and hares, foxes and grapes, and wolves in sheep's clothing has been a part of world literature for over two thousand years. Since the time of the Ancient Greeks successive generations have drawn moral lessons from his fables, and over history his animals' exploits have been used to support differing ideals. Malcolm X was a fan, as was Imperial Britain, the Nazis had their version and the Trade Union movement published the fables too. There are over 700 fables, and they are supposedly written by a black slave far clever than his philosopher master. Bridget Kendall traces the origin and meaning of Aesop's fables and explores what they can teach us about understanding our own extraordinary times with three world experts: Edith Hall, Professor of Classics at Kings College London; Vayos Liapis, Professor of Theatre at the Open University of Cyprus; Dan-el Padilla Peralta, Associate Professor of Classics at Princeton University.

Bridget Kendall, an expert in color theory, leads a fascinating discussion on Johann Wolfgang von Goethe's impact on art and color perception. The dialogue dives into how Goethe's 'The Theory of Colours' contrasts with Newton's views, revealing the emotional weight colors carry. Highlights include the dual meanings of red in African textiles, the history of color in art, and the innovative solutions of the Gobelin tapestry company. The experts emphasize the evolving relationship between color, emotion, and cultural exchange throughout history.

From 1849, hundreds of thousands of prospectors from across the USA headed for California in the hope of finding gold. Some made great fortunes, and there was a new Californian dream for these 49ers, willing to risk everything and, if they failed, to try again. California was to become the engine house of the US economy, while expanding so rapidly that it unbalanced the free and slave-owning states and hastened the USA towards civil war. Yet the new arrivals also drove out competing miners from around the Pacific who had reached the goldfields first, and destroyed the lives of Native Americans there, and excluded Chinese people who had begun to settle, with lasting consequences.Joining Bridget Kendall to explore who won and who lost in the California Gold Rush are Cliff Trafzer, Distinguished Professor of History at the University of California, Riverside; Mae Ngai, Professor of History at Columbia University, and author of the forthcoming book The Chinese Question, a study of Chinese gold miners; and HW Brands, Professor of History at The University of Texas at Austin and author of Dreams of El Dorado: A History of the American West.(Image: Gold Nuggets Credit: bodnarchuk/Getty Images)

A century ago a deadly flu virus swept the planet, uniting the world in a disaster on a par with World War One. Over 50 million people died. Social distancing was put in place but drugs were ineffective, there was no vaccine, and in many places medicine could not cope. The world recovered but was never the same again. What can the last great pandemic teach us about how to combat Covid-19 today? Three world experts join Bridget Kendall: Laura Spinney, science journalist and author of Pale Rider: The Spanish Flu of 1918 and How it Changed the World;. Svenn Erik Mamelund, historical demographer and research professor at Oslo Metropolitan University; Siddharth Chandra, director of the Asian Studies Centre and professor at James Madison College, Michigan State University.(Photo: Japanese school girls wear protective masks to guard against the influenza outbreak.

It’s the map of the world we all recognise today, but until Gerard Mercator came up with his elegant solution in 1569, the question of how to turn the earth’s three dimensional sphere into a flat image had long flummoxed mapmakers. Nearly 500 years later, Mercator’s model is still the standard for modern mapmaking. What makes it so enduring?Joining Rajan Datar to discuss the man who defined the way we see the world are geographer and explorer Nicholas Crane, philosopher Emily Thomas and professor of cartography Philippe De Maeyer.Illustration: Portrait of Gerard Mercator, Flemish cartographer (born Gerard de Kremer, 1512 - 1594).

How many people can lay claim to playing a key role in three different 20th century protest movements across the world, each of which largely succeeded in their aims? Margaret ‘Gretta’ Cousins, the daughter of a minor court official from Boyle in Ireland and a musician by profession certainly can. The common thread in all of these battles for this driven, feisty activist was the demand for equality for women: Gretta Cousins spent time in jails in Ireland, England and India for her beliefs and remained a catalyst for change throughout her life. As a suffragette she was involved in high-profile direct action in London and Dublin, while in India she not only contributed to the improvement of women’s lives but also became the country’s first female magistrate.Rajan Datar is joined by historians Dr. Margaret Ward from Queen's University in Belfast, Dr. Jyoti Atwal from Jawaharlal Nehru University, New Delhi and University of Limerick and Dr. Emily Rook-Koepsel from the University of Pittsburgh.(Photo: Margaret Cousins, c.1931)
