Melvyn Bragg and guests discuss the link between archaeology and imperialism. In 1842 a young English adventurer called Austen Henry Layard set out to excavate what he hoped were the remains of the biblical city of Nineveh in Mesopotamia. On arrival he discovered that the local French consul, Paul Emile Botta, was already hard at work. Across the Middle East and in Egypt, archaeologists, antiquarians and adventurers were exploring cities older than the Bible and shipping spectacular monuments down the Nile and the Tigris to burgeoning European museums.What was it about the ancient cultures of Egypt and Mesopotamia that so gripped the 19th century imagination? How did nationalism and imperialism affect the search for the ancient past and how did archaeology evolve from its adventuresome, even reckless, origins into the science of artefacts we know today?With Tim Champion, Professor of Archaeology, University of Southampton; Richard Parkinson, Assistant Keeper in the Department of Ancient Egypt and Sudan at the British Museum; Eleanor Robson, Lecturer in the History and Philosophy of Science at Cambridge University and a Fellow of All Souls College, Oxford.

Melvyn Bragg and guests discuss King Alfred and the defeat of the Vikings at Battle of Edington. At the end of the 9th century the Vikings controlled almost all of what we now call England. Mercia had fallen and its king had fled, Northumbria had fallen and so had Essex. The only independent kingdom left standing against the rampaging Danes was Wessex, and Alfred the Great; then he was overrun, his treasury, palaces and castles taken whilst he and his most loyal followers were left to wander the moors. Yet he came back. The Battle of Edington in 878 is taken by many to be the great founding Battle of England. It is the conflict in which Alfred, King of Wessex, came back to defeat the Vikings and launch a grand project to establish a new entity of Englishness, what he called the 'Anglecynn' in the South of the island of Britain.How did Alfred manage to defeat the Vikings when he had been so thoroughly routed? What motivated his project to fashion Englishness? And without Edington, would there be no England?With Richard Gameson, Reader in Medieval History, University of Kent at Canterbury; Sarah Foot, Professor of Early Medieval History, University of Sheffield; John Hines, Professor in the School of History and Archaeology, Cardiff University.

Meet John Ruskin, a brilliant art critic who criticized Victorian society through art and architecture. He praised Gothic architecture for its imperfections and craftsmanship while condemning capitalist ideals. Learn about Ruskin's early influences, his vision of society, and his lasting impact on figures like Gandhi and Tolstoy.

Melvyn Bragg and guests discuss the heavenly host of Angels. George Bernard Shaw made the observation that "in heaven an angel is nobody in particular", but there is nothing commonplace about this description of angels from the Bible's book of Ezekiel:"They had the likeness of a man. And every one had four faces, and every one had four wings. And their feet were straight feet; and the sole of their feet was like the sole of a calf's foot: and they sparkled like the colour of burnished brass.... As for the likeness of their faces, they four had the face of a man, and the face of a lion, on the right side: and they four had the face of an ox on the left side; they four also had the face of an eagle." With angels like that, it is easy to see why they have caused so much controversy over the centuries.What part have angels played in western religion? How did they get their halos and their wings? And what are they really: Gods or men?With Martin Palmer, theologian and Director of the International Consultancy on Religion, Education and Culture; Valery Rees, Renaissance Scholar at the School of Economic Science; John Haldane, Professor of Philosophy, University of St Andrews.

Melvyn Bragg and guests discuss 'dark energy'. Only 5% of our universe is composed of visible matter, stars, planets and people; something called 'dark matter' makes up about 25% and an enormous 70% of the universe is pervaded with the mysteriously named 'dark energy'. It is a recent discovery and may be only a conjecture, but it has been invoked to explain an abiding riddle of the cosmos: if the expansion of the universe is powered by the energy of the Big Bang, then why isn't the expansion slowing down over time as the initial energy runs down and the attractive force of gravity asserts itself? Scientists had predicted a Big Crunch as the logical opposite of the Big Bang, but far from retracting, the expansion of the universe is actually accelerating...it's running away with itself.How do we know that the universe is behaving like this and what's causing it? If dark energy is the culprit, then what is this elusive, though omnipresent entity?With Sir Martin Rees, Astronomer Royal and Professor of Cosmology and Astrophysics, Cambridge University; Carolin Crawford, Royal Society University Research Fellow at the Institute of Astronomy, University of Cambridge; Sir Roger Penrose, Emeritus Rouse Ball Professor of Maths at Oxford University.

Melvyn Bragg and guests discuss the mad, bad world of modern utopias. "I want to gather together about twenty souls," wrote D H Lawrence in 1915, "and sail away from this world of war and squalor and find a little colony where there shall be no money but a sort of communism as necessaries of life go, and some real decency". Utopias were in the air in the first decades of the 20th century and the literature of the period abounds with worlds of imagined escape, feminist utopias, technological nightmares and rich imaginings of the world as it could or should become. Many of the societies that writers like H G Wells created were meant seriously, as signposts to a future that would seem horrific to us now, where the weak are eradicated and the strong prosper and procreate.What was it about that era that brought forward so many imagined futures? How did utopias become the dystopias of Brave New World and 1984, and why are writers so much less likely to create a Utopia now?With John Carey, Emeritus Professor of English Literature, Oxford University and editor of The Faber Book of Utopias; Steve Connor, Professor of Modern Literature at Birkbeck, University of London; Laura Marcus, Professor of English, University of Sussex.
