In Our Time With Melvyn Bragg Folgen

Melvyn Bragg and guests discuss the devastating mass extinctions of the Late Devonian Period, roughly 370 million years ago, when around 70 percent of species disappeared. Scientists are still trying to establish exactly what happened, when and why, but this was not as sudden as when an asteroid hits Earth. The Devonian Period had seen the first trees and soils and it had such a diversity of sea life that it’s known as the Age of Fishes, some of them massive and armoured, and, in one of the iconic stages in evolution, some of them moving onto land for the first time. One of the most important theories for the first stage of this extinction is that the new soils washed into oceans, leading to algal blooms that left the waters without oxygen and suffocated the marine life.

In this 900th edition of the programme, Melvyn Bragg and guests discuss one of the best known and most influential of the poems of the Romantic movement. Samuel Taylor Coleridge (1772-1834) wrote The Rime of the Ancient Mariner in 1798 after discussions with his friend Wordsworth. He refined it for the rest of his life, and it came to define him, a foreshadowing of his opium-addicted, lonely wandering and deepening sense of guilt. The poem tells of a sailor compelled to tell and retell the story of a terrible voyage in his youth, this time as guests are heading to a wedding party, where he stoppeth one of three.The image above is from Gustave Doré's illustration of the mariner's shooting of the albatross, for an 1877 German language edition of the poemWithSir Jonathan Bate Professor of Environmental Humanities at Arizona State UniversityTom Mole Professor of English Literature and Book History at the University of EdinburghAnd Rosemary Ashton Emeritus Quain Professor of English Language and Literature at University College LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the man who, according to Machiavelli, was the last of the Five Good Emperors. Marcus Aurelius, 121 to 180 AD, has long been known as a model of the philosopher king, a Stoic who, while on military campaigns, compiled ideas on how best to live his life, and how best to rule. These ideas became known as his Meditations, and they have been treasured by many as an insight into the mind of a Roman emperor, and an example of how to avoid the corruption of power in turbulent times.The image above shows part of a bronze equestrian statue of Marcus Aurelius.With Simon Goldhill Professor of Greek Literature and Culture and Fellow of King’s College, CambridgeAngie Hobbs Professor of the Public Understanding of Philosophy at the University of SheffieldAndCatharine Edwards Professor of Classics and Ancient History at Birkbeck, University of LondonProducer: Simon Tillotson
