Melvyn Bragg and guests discuss George Orwell's (1903-1950) final novel, published in 1949, set in a dystopian London which is now found in Airstrip One, part of the totalitarian superstate of Oceania which is always at war and where the protagonist, Winston Smith, works at the Ministry of Truth as a rewriter of history: 'Who controls the past,' ran the Party slogan, 'controls the future: who controls the present controls the past.' The influence of Orwell's novel is immeasurable, highlighting threats to personal freedom with concepts he named such as doublespeak, thoughtcrime, Room 101, Big Brother, memory hole and thought police.With David Dwan Professor of English Literature and Intellectual History at the University of OxfordLisa Mullen Teaching Associate in Modern Contemporary Literature at the University of CambridgeAndJohn Bowen Professor of English Literature at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss the origin of this personification of the English everyman and his development as both British and Britain in the following centuries. He first appeared along with Lewis Baboon (French) and Nicholas Frog (Dutch) in 1712 in a pamphlet that satirised the funding of the War of the Spanish Succession. The author was John Arbuthnot (1667-1735), a Scottish doctor and satirist who was part of the circle of Swift and Pope, and his John Bull was the English voter, overwhelmed by taxes that went not so much into the war itself but into the pockets of its financiers. For the next two centuries, Arbuthnot’s John Bull was a gift for cartoonists and satirists, especially when they wanted to ridicule British governments for taking advantage of the people’s patriotism.

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.WithPiphal Heng Postdoctoral scholar at the Cotsen Institute and the Programme for Early Modern Southeast Asia at UCLAAshley Thompson Hiram W Woodward Chair of Southeast Asian Art at SOAS University of LondonAndSimon Warrack A stone conservator who has worked extensively at Angkor WatProducer: Simon Tillotson

Melvyn Bragg and guests discuss the celebrated Welsh poet, Dylan Thomas (1914 - 1953). He wrote some of his best poems before he was twenty in the first half of his short, remarkable life, and was prolific in the second half too with poems such as those set in London under the Blitz and reworkings of his childhood in Swansea, and his famous radio play Under Milk Wood (performed after his death). He was read widely and widely heard: with his reading tours in America and recordings of his works that sold in their hundreds of thousands after his death, he is credited with reviving the act of poetry as performance in the 20th century.WithNerys Williams Associate Professor of Poetry and Poetics at University College DublinJohn Goodby Professor of Arts and Culture at Sheffield Hallam UniversityAndLeo Mellor The Roma Gill Fellow in English at Murray Edwards College, University of CambridgeProducer: Simon Tillotson

Melvyn Bragg and guests discuss the abrupt transformation of stars after shining brightly for millions or billions of years, once they lack the fuel to counter the force of gravity. Those like our own star, the Sun, become red giants, expanding outwards and consuming nearby planets, only to collapse into dense white dwarves. The massive stars, up to fifty times the mass of the Sun, burst into supernovas, visible from Earth in daytime, and become incredibly dense neutron stars or black holes. In these moments of collapse, the intense heat and pressure can create all the known elements to form gases and dust which may eventually combine to form new stars, new planets and, as on Earth, new life.The image above is of the supernova remnant Cassiopeia A, approximately 10,000 light years away, from a once massive star that died in a supernova explosion that was first seen from Earth in 1690WithMartin Rees Astronomer Royal, Fellow of Trinity College, CambridgeCarolin Crawford Emeritus Member of the Institute of Astronomy and Emeritus Fellow of Emmanuel College, University of CambridgeAndMark Sullivan Professor of Astrophysics at the University of SouthamptonProducer: Simon Tillotson

Melvyn Bragg and guests discuss ideas of Georg Wilhelm Friedrich Hegel (1770 - 1831) on history. Hegel, one of the most influential of the modern philosophers, described history as the progress in the consciousness of freedom, asking whether we enjoy more freedom now than those who came before us. To explore this, he looked into the past to identify periods when freedom was moving from the one to the few to the all, arguing that once we understand the true nature of freedom we reach an endpoint in understanding. That end of history, as it's known, describes an understanding of freedom so far progressed, so profound, that it cannot be extended or deepened even if it can be lost.WithSally Sedgwick Professor and Chair of Philosophy at Boston UniversityRobert Stern Professor of Philosophy at the University of SheffieldAnd Stephen Houlgate Professor of Philosophy at the University of WarwickProducer: 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 RikjsmuseumWithVladimir Urbanek Senior Researcher in the Department of Comenius Studies and Early Modern Intellectual History at the Institute of Philosophy of the Czech Academy of SciencesSuzanna Ivanic Lecturer in Early Modern European History at the University of KentAndHoward Hotson Professor of Early Modern Intellectual History at the University of Oxford and Fellow of St Anne’s CollegeProducer: Simon Tillotson

Melvyn Bragg and guests discuss two of China’s greatest poets, Li Bai and Du Fu, who wrote in the 8th century in the Tang Era. Li Bai (701-762AD) is known for personal poems, many of them about drinking wine, and for finding the enjoyment in life. Du Fu (712-770AD), a few years younger, is more of an everyman, writing in the upheaval of the An Lushan Rebellion (755-763AD). Together they have been a central part of Chinese culture for over a millennium, reflecting the balance between the individual and the public life, and one sign of their enduring appeal is that there is rarely agreement on which of them is the greater.The image above is intended to depict Du Fu.With Tim Barrett Professor Emeritus of East Asian History at SOAS, University of LondonTian Yuan Tan Shaw Professor of Chinese at the University of Oxford and Professorial Fellow at University CollegeAndFrances Wood Former Curator of the Chinese Collections at the British LibraryProducer: Simon Tillotson

Melvyn Bragg and guests discuss the impact of David I of Scotland (c1084-1153) on his kingdom and on neighbouring lands. The youngest son of Malcolm III, he was raised in exile in the Anglo-Norman court and became Earl of Huntingdon and Prince of Cumbria before claiming the throne in 1124. He introduced elements of what he had learned in England and, in the next decades, his kingdom saw new burghs, new monasteries, new ways of governing and the arrival of some very influential families, earning him the reputation of The Perfect King.With Richard Oram Professor of Medieval and Environmental History at the University of StirlingAlice Taylor Professor of Medieval History at King’s College LondonAndAlex Woolf Senior Lecturer in History at the University of St AndrewsProducer: 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, FranceWith:Candida Moss Edward Cadbury Professor of Theology at the University of BirminghamKate Cooper Professor of History at Royal Holloway, University of LondonAndJames Corke-Webster Senior Lecturer in Classics, History and Liberal Arts at King’s College LondonProducer: Simon Tillotson
