Melvyn Bragg and guests discuss the largest and arguably the most astonishing religious structure on Earth, built for Suryavarman II in the 12th Century in modern-day Cambodia. It is said to have more stone in it than the Great Pyramid of Giza, and much of the surface is intricately carved and remarkably well preserved. For the last 900 years Angkor Wat has been a centre of religion, whether Hinduism, Buddhism or Animism or a combination of those, and a source of wonder to Cambodians and visitors from around the world. With Piphal Heng Postdoctoral scholar at the Cotsen Institute and the Programme for Early Modern Southeast Asia at UCLA Ashley Thompson Hiram W Woodward Chair of Southeast Asian Art at SOAS University of London And Simon Warrack A stone conservator who has worked extensively at Angkor Wat Producer: Simon Tillotson

Melvyn Bragg and guests discuss the Czech educator Jan Amos Komenský (1592-1670) known throughout Europe in his lifetime under the Latin version of his name, Comenius. A Protestant and member of the Unity of Brethren, he lived much of his life in exile, expelled from his homeland under the Catholic Counter-Reformation, and he wanted to address the deep antagonisms underlying the wars that were devastating Europe especially The Thirty Years War (1618-1648). A major part of his plan was Universal Education, in which everyone could learn about everything, and better understand each other and so tolerate their religious differences and live side by side. His ideas were to have a lasting influence on education, even though the peace that followed the Thirty Years War only entrenched the changes in his homeland that made his life there impossible. The image above is from a portrait of Comenius by Jürgen Ovens, 1650 - 1670, painted while he was living in Amsterdam and held in the Rikjsmuseum With Vladimir Urbanek Senior Researcher in the Department of Comenius Studies and Early Modern Intellectual History at the Institute of Philosophy of the Czech Academy of Sciences Suzanna Ivanic Lecturer in Early Modern European History at the University of Kent And Howard Hotson Professor of Early Modern Intellectual History at the University of Oxford and Fellow of St Anne’s College Producer: Simon Tillotson

Melvyn Bragg and guests discuss the accounts by Eusebius of Caesarea (c260-339 AD) and others of the killings of Christians in the first three centuries after the crucifixion of Jesus. Eusebius was writing in a time of peace, after The Great Persecution that had started with Emperor Diocletian in 303 AD and lasted around eight years. Many died under Diocletian, and their names are not preserved, but those whose deaths are told by Eusebius became especially celebrated and their stories became influential. Through his writings, Eusebius shaped perceptions of what it meant to be a martyr in those years, and what it meant to be a Christian. The image above is of The Martyrdom of Saint Blandina (1886) at the Church of Saint-Blandine de Lyon, France With: Candida Moss Edward Cadbury Professor of Theology at the University of Birmingham Kate Cooper Professor of History at Royal Holloway, University of London And James Corke-Webster Senior Lecturer in Classics, History and Liberal Arts at King’s College London Producer: Simon Tillotson

Melvyn Bragg and guests discuss the astonishing work of Michelangelo (1477-1564) in this great chapel in the Vatican, firstly the ceiling with images from Genesis (of which the image above is a detail) and later The Last Judgement on the altar wall. For the Papacy, Michelangelo's achievement was a bold affirmation of the spiritual and political status of the Vatican, of Rome and of the Catholic Church. For the artist himself, already famous as the sculptor of David in Florence, it was a test of his skill and stamina, and of the potential for art to amaze which he realised in his astonishing mastery of the human form. With Catherine Fletcher Professor of History at Manchester Metropolitan University Sarah Vowles The Smirnov Family Curator of Italian and French Prints and Drawings at the British Museum And Matthias Wivel The Aud Jebsen Curator of Sixteenth-Century Italian Paintings at the National Gallery Producer: Simon Tillotson
