In Our Time With Melvyn Bragg Folgen

Melvyn Bragg and guests discuss the voyage of HMS Challenger which set out from Portsmouth in 1872 with a mission a to explore the ocean depths around the world and search for new life. The scale of the enterprise was breath taking and, for its ambition, it has since been compared to the Apollo missions. The team onboard found thousands of new species, proved there was life on the deepest seabeds and plumbed the Mariana Trench five miles below the surface. Thanks to telegraphy and mailboats, its vast discoveries were shared around the world even while Challenger was at sea, and they are still being studied today, offering insights into the ever-changing oceans that cover so much of the globe and into the health of our planet.The image above is from the journal of Pelham Aldrich R.N. who served on the Challenger Surveying Expedition from 1872-5.WithErika Jones Curator of Navigation and Oceanography at Royal Museums GreenwichSam Robinson Southampton Marine and Maritime Institute Research Fellow at the University of SouthamptonAndGiles Miller Principal Curator of Micropalaeontology at the Natural History Museum LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the speeches that became a byword for fierce attacks on political opponents. It was in the 4th century BC, in Athens, that Demosthenes delivered these speeches against the tyrant Philip II of Macedon, father of Alexander the Great, when Philip appeared a growing threat to Athens and its allies and Demosthenes feared his fellow citizens were set on appeasement. In what became known as The Philippics, Demosthenes tried to persuade Athenians to act against Macedon before it was too late; eventually he succeeded in stirring them, even if the Macedonians later prevailed. For these speeches prompting resistance, Demosthenes became famous as one of the Athenian democracy’s greatest freedom fighters. Later, in Rome, Cicero's attacks on Mark Antony were styled on Demosthenes and these too became known as Philippics.The image above is painted on the dome of the library of the National Assembly, Paris and is by Eugene Delacroix (1798-1863). It depicts Demosthenes haranguing the waves of the sea as a way of strengthening his voice for his speeches.With Paul Cartledge A. G.

Melvyn Bragg and guests discuss the Bauhaus which began in 1919 in Weimar, Germany, as a school for arts and crafts combined, and went on to be famous around the world. Under its first director, Walter Gropius, the Bauhaus moved to Dessau and extended its range to architecture and became associated with a series of white, angular, flat-roofed buildings reproduced from Shanghai to Chicago, aimed for modern living. The school closed after only 14 years while at a third location, Berlin, under pressure from the Nazis, yet its students and teachers continued to spread its ethos in exile, making it even more influential.The image above is of the Bauhaus Building, Dessau, designed by Gropius and built in 1925-6WithRobin Schuldenfrei Tangen Reader in 20th Century Modernism at The Courtauld Institute of ArtAlan Powers History Leader at the London School of ArchitectureAnd Michael White Professor of the History of Art at the University of YorkProducer: Simon Tillotson
