The Measurement of Time

Melvyn Bragg and his guests discuss the measurement of time. Early civilisations used the movements of heavenly bodies to tell the time, but even in the ancient world more sophisticated timekeeping devices such as waterclocks were known. The development of mechanical clocks in Europe emerged in the medieval period when monks used such devices to sound an alarm to signal it was the hour to pray, although these clocks did not tell them the time. For hundreds of years clocks were inaccurate and it proved hard to remedy the problems, let alone settle on a standard time that the country should follow. It was with the advent of the railways that time finally became standardised in Britain in the mid-19th century and only in 1884 that Greenwich became the prime meridian of the world. Atomic clocks now mark the passing of the days, hours, and minutes and they are capable of keeping time to a second in 15 million years.

Moses Mendelssohn

Melvyn Bragg and his guests discuss the work and influence of the eighteenth-century philosopher Moses Mendelssohn. A prominent figure at the court of Frederick the Great, Mendelssohn was one of the most significant thinkers of his age. He came from a humble, but culturally rich background and his obvious intelligence was recognised from a young age and nurtured by the local rabbi where he lived in the town of Dessau in Prussia. Moses's learning earned him the sobriquet of the 'German Socrates' and he is considered to be one of the principal architects of the Haskala, the Jewish Enlightenment, and widely regarded as having helped bring Judaism into the mainstream of European culture. Mendelssohn is perhaps best remembered today for his efforts to bring Jewish and German culture closer together and for his plea for religious toleration.With:Christopher ClarkProfessor of Modern European History at the University of CambridgeAbigail GreenTutor and Fellow in History at the University of OxfordAdam SutcliffeSenior Lecturer in European History at King's College, London Producer: Natalia Fernandez.

Vitruvius and De Architectura

Melvyn Bragg and his guests discuss Vitruvius' De Architectura. Written almost exactly two thousand years ago, Vitruvius' work is a ten-volume treatise on engineering and architecture, the only surviving work on the subject from the ancient world. This fascinating book offers unique insights into Roman technology and contains discussion of the general principles of architecture, the training of architects and the design of temples, houses and public buildings.The rediscovery of this seminal treatise in the 15th century provided the impetus for the neoclassical architectural movement, and Vitruvius exerted a significant influence on the work of Renaissance architects including Palladio, Brunelleschi and Alberti. It remains a hugely important text today, two millennia after it was written.With:Serafina CuomoReader in Roman History at Birkbeck, University of LondonRobert TavernorEmeritus Professor of Architecture and Urban Design at the London School of EconomicsAlice KoenigLecturer in Latin and Classical Studies at the University of St Andrews.Producer: Thomas Morris.

Lyrical Ballads

Melvyn Bragg and his guests discuss Lyrical Ballads, the collection of poems by William Wordsworth and Samuel Coleridge first published in 1798. The work was conceived as an attempt to cast off the stultifying conventions of formal 18th-century poetry. Wordsworth wrote that the poems it contains should be "considered as experiments. They were written chiefly with a view to ascertain how far the language of conversation in the middle and lower classes of society is adapted to the purpose of poetic pleasure."Lyrical Ballads contains some of the best-known work by Coleridge and Wordsworth, including The Rime of the Ancient Mariner and Tintern Abbey - and is today seen as a point of radical departure for poetry in English.With:Judith HawleyProfessor of Eighteenth-Century Literature at Royal Holloway, University of LondonJonathan BateProvost of Worcester College, OxfordPeter SwaabReader in English Literature at University College London.Producer: Thomas Morris.

Erasmus

Melvyn Bragg and his guests discuss the life and work of the Dutch humanist scholar Desiderius Erasmus. In his lifetime Erasmus was almost universally recognised as the greatest classical scholar of his age, the translator and editor of numerous Latin and Greek texts. But above all he was a religious scholar who published important editions of the Bible which expunged many corruptions to the texts of the Scriptures. He was an outspoken critic of the Church, whose biting satire on its excesses, In Praise of Folly, was famed throughout Europe.When the Reformation began in 1517, however, Erasmus chose to remain a member of the Catholic Church rather than side with Martin Luther and the reformers, and a few years later he engaged in a celebrated debate with Luther on the subject of free will. Through his writings on the Church, on education and the wide gamut of humanist scholarship, Erasmus is remembered today as one of the greatest thinkers of the northern Renaissance.With:Diarmaid MacCullochProfessor of the History of the Church at the University of OxfordEamon DuffyProfessor of the History of Christianity at the University of CambridgeJill KrayeProfessor of the History of Renaissance Philosophy and Librarian at the Warburg Institute, University of London.Producer: Thomas Morris.
