The history of the world as told through one hundred objects. This week Neil MacGregor, the director of the British Museum, is exploring the world in the 7th Century, at a time when the teachings of Islam were transforming the Middle East and goods and ideas were flowing both ways along the tangle of connections that have become known as the Silk Road. But what was happening in Britain at this time? In today's programme, Neil travels to East Anglia to describe the sensational burial discovery that has been hailed as a "British Tutankhamen". He tells the story of the Sutton Hoo helmet, the world it inhabited and the imagination it has inspired. The poet Seamus Heaney reflects on the helmet in the context of the great Anglo-Saxon epic poem, Beowulf, and the archaeologist Angus Wainwright describes the discovery of the great grave ship where the helmet was found.
