Melvyn Bragg and guests discuss the remarkable diversity of the animals that dominated life on land in the Triassic, before the rise of the dinosaurs in the Jurassic, and whose descendants are often described wrongly as 'living fossils'. For tens of millions of years, the ancestors of alligators and Nile crocodiles included some as large as a bus, some running on two legs like a T Rex and some that lived like whales. They survived and rebounded from a series of extinction events but, while the range of habitats of the dinosaur descendants such as birds covers much of the globe, those of the crocodiles have contracted, even if the animals themselves continue to evolve today as quickly as they ever have.

The Valladolid Debate (Summer Repeat)

Melvyn Bragg and guests discuss the debate in Valladolid, Spain in 1550, over Spanish rights to enslave the native peoples in the newly conquered lands. Bartolomé de Las Casas (pictured above), the Bishop of Chiapas, Mexico, was trying to end the encomienda system in which those who now owned the land could also take the people in forced labour. Juan Gines Sepulveda, a philosopher, argued for the colonists' property rights over people, asserting that some native Americans were 'natural slaves' as defined by Aristotle. Valladolid became seen as the first open attempt by European colonists to discuss the ethics of slavery, and Las Casas became known as 'Saviour of the Indians' and an advocate for human rights, although for some time he argued that African slaves be imported to do the work in place of the native people, before repenting.

Edward Gibbon (Summer Repeat)

1 Recommendations

Melvyn Bragg and guests discuss the life and ideas of one of the great historians, best known for his History of the Decline and Fall of the Roman Empire (published 1776-89). According to Gibbon (1737-94) , the idea for this work came to him on 15th of October 1764 as he sat musing amidst the ruins of Rome, while barefooted friars were singing vespers in the Temple of Jupiter. Decline and Fall covers thirteen centuries and is an enormous intellectual undertaking and, on publication, it became a phenomenal success across Europe.
