Melvyn Bragg and guests discuss the treaties France entered into with the United States of America in 1778, to give open support to the USA in its revolutionary war against Britain and to promote French trade across the Atlantic. This alliance had profound consequences for all three. The French navy, in particular, played a decisive role in the Americans’ victory in their revolution, but the great cost of supporting this overseas war fell on French taxpayers, highlighting the need for reforms which in turn led to the French Revolution. Then, when France looked to its American ally for support in the new French revolutionary wars with Britain, Americans had to choose where their longer term interests lay, and they turned back from the France that had supported them to the Britain they had just been fighting, and France and the USA fell into undeclared war at sea.The image above is a detail of Bataille de Yorktown by Auguste Couder, with Rochambeau commanding the French expeditionary force in 1781With Frank Cogliano Professor of American History at the University of EdinburghKathleen Burk Professor Emerita of Modern and Contemporary History at University College LondonAndMichael Rapport Reader in Modern European History at the University of GlasgowProducer: Simon Tillotson

Melvyn Bragg and guests discuss the form of Christianity adopted by Ostrogoths in the 4th century AD, which they learned from Roman missionaries and from their own contact with the imperial court at Constantinople. This form spread to the Vandals and the Visigoths, who took it into Roman Spain and North Africa, and the Ostrogoths brought it deeper into Italy after the fall of the western Roman empire. Meanwhile, with the Roman empire in the east now firmly committed to the Nicene Creed not the Arian, the Goths and Vandals faced conflict or conversion, as Arianism moved from an orthodox view to being a heresy that would keep followers from heaven and delay the Second Coming for all.The image above is the ceiling mosaic of the Arian Baptistry in Ravenna, commissioned by Theodoric, ruler of the Ostrogothic Kingdom of Italy, around the end of the 5th centuryWithJudith Herrin Professor of Late Antique and Byzantine Studies, Emeritus, at King's College LondonRobin Whelan Lecturer in Mediterranean History at the University of LiverpoolAndMartin Palmer Visiting Professor in Religion, History and Nature at the University of WinchesterProducer: Simon Tillotson

Melvyn Bragg and guests discuss Laplace (1749-1827) who was a giant in the world of mathematics both before and after the French Revolution. He addressed one of the great questions of his age, raised but side-stepped by Newton: was the Solar System stable, or would the planets crash into the Sun, as it appeared Jupiter might, or even spin away like Saturn threatened to do? He advanced ideas on probability, long the preserve of card players, and expanded them out across science; he hypothesised why the planets rotate in the same direction; and he asked if the Universe was deterministic, so that if you knew everything about all the particles then you could predict the future. He also devised the metric system and reputedly came up with the name 'metre'.
