In Our Time

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.

Melvyn Bragg and guests discuss the great Roman military disaster of 9 AD when Germanic tribes under Arminius ambushed and destroyed three legions under Varus. According to Suetonius, emperor Augustus hit his head against the wall when he heard the news, calling on Varus to give him back his legions. The defeat ended Roman expansion east of the Rhine. Victory changed the development of the Germanic peoples, both in the centuries that followed and in the nineteenth century when Arminius, by then known as Herman, became a rallying point for German nationalism.

Melvyn Bragg and guests discuss the works and life of one of the most popular writers in Europe in C19th, Amantine Lucile Aurore Dupin (1804-1876) who wrote under the name George Sand. When she wrote her first novel under that name, she referred to herself as a man. This was in Indiana (1832), which had the main character breaking away from her unhappy marriage. It made an immediate impact as it overturned the social conventions of the time and it drew on her own early marriage to an older man, Casimir Dudevant. Once Sand's identity was widely known, her works became extremely popular in French and in translation, particularly her rural novels, outselling Hugo and Balzac in Britain, perhaps buoyed by an interest in her personal life, as well as by her ideas on the rights and education of women and strength of her writing.

Melvyn Bragg and guests discuss Alcuin of York, c735-804AD, who promoted education as a goal in itself, and had a fundamental role in the renaissance at Charlemagne's court. He wrote poetry and many letters, hundreds of which survive and provide insight into his life and times. He was born in or near York and spent most of his life in Northumbria before accepting an invitation to Charlemagne's court in Aachen. To this he brought Anglo-Saxon humanism, encouraging a broad liberal education for itself and the better to understand Christian doctrine. He left to be abbot at Marmoutier, Tours, where the monks were developing the Carolingian script that influenced the Roman typeface. The image above is Alcuin’s portrait, found in a copy of the Bible made at his monastery in Tours during the rule of his successor Abbot Adalhard (834–843). Painted in red on gold leaf, it shows Alcuin with a tonsure and a halo, signifying respect for his memory at the monastery where he had died in 804. His name and rank are spelled out alongside: Alcvinvs abba, ‘Alcuin the abbot’. It is held at the Staatsbibliothek Bamberg -Kaiser-Heinrich-Bibliothek - Msc.Bibl.1,fol.5v (photo by Gerald Raab).

Melvyn Bragg and guests discuss the flow of particles from the outer region of the Sun which we observe in the Northern and Southern Lights, interacting with Earth's magnetosphere, and in comet tails that stream away from the Sun regardless of their own direction. One way of defining the boundary of the solar system is where the pressure from the solar wind is balanced by that from the region between the stars, the interstellar medium. Its existence was suggested from the C19th and Eugene Parker developed the theory of it in the 1950s and it has been examined and tested by a series of probes in C20th up to today, with more planned.
