The Director of the British Museum, Neil MacGregor, retells the history of human development from the first stone axe to the credit card using 100 selected objects from the Museum. Today Neil has chosen an object found in France, dating back 13,000 years. It is a carving of two swimming reindeer and it's not just the likeness that is striking. The creator of this carving was one of the first humans to express their world through art. But why did they do it? Neil MacGregor tells the story of the Swimming Reindeer, and its place in the history of art and religion with contributions from the Archbishop of Canterbury Dr Rowan Williams and archaelogist Professor Steven Mithen.Producer: Anthony Denselow
