In Our Time Folgen

After 27 years, Melvyn Bragg has decided to step down from the In Our Time presenter’s chair. With over a thousand episodes to choose from, he has selected just six that capture the huge range and depth of the subjects he and his experts have tackled. In this first pick, we hear Melvyn Bragg and his guests discuss the origins, science and mythology of the moon. Humans have been fascinated by our only known satellite since prehistory. In some cultures the Moon has been worshipped as a deity; in recent centuries there has been lively debate about its origins and physical characteristics. Although other planets in our solar system have moons ours is, relatively speaking, the largest, and is perhaps more accurately described as a 'twin planet'; the past, present and future of the Earth and the Moon are locked together. Only very recently has water been found on the Moon - a discovery which could prove to be invaluable if human colonisation of the Moon were ever to occur. Mankind first walked on the Moon in 1969, but it is debatable how important this huge political event was in developing our scientific knowledge. The advances of space science, including data from satellites and the moon landings, have given us some startling insights into the history of our own planet, but many intriguing questions remain unanswered.

In each episode, host Melvyn Bragg and expert guests explore the characters, events and discoveries that have shaped our world.

Melvyn Bragg and his guests discuss the Siege of Tenochtitlan. In 1521 the Spanish conquistador Hernan Cortes led an army of Spanish and native forces against the city of Tenochtitlan, the spectacular island capital of the Aztec civilisation. At first Cortes had been welcomed by the Aztec leader, Moctezuma, and he and his men were treated like kings. But their friendship proved short-lived, and soon celebrations turned into vicious fighting. After a prolonged siege and fierce battle, in which many thousands died, the city finally fell. This major confrontation between Old and New Worlds precipitated the downfall of the Aztec Empire, and marked a new phase in European colonisation of the Americas.With:Alan Knight Professor of the History of Latin America at the University of OxfordElizabeth GrahamProfessor of Mesoamerican Archaeology at University College, LondonCaroline Dodds Pennock Lecturer in International History at the University of Sheffield Producer: Natalia Fernandez.

Melvyn Bragg and his guests discuss Delacroix's painting Liberty Leading the People. In 1830 revolution once more overtook France, when a popular uprising toppled the French king Charles X. A few months later, the artist Eugene Delacroix immortalised the events of the July Revolution in a painting which remains one of the icons of the age. His allegorical depiction of a Paris barricade, with the figure of Liberty clutching a tricolore while standing on a pile of corpses, is a powerful image which has provoked much debate in the years since it was first unveiled to an enthusiastic public.Producer: Natalia Fernandez.
