A 6,000-year-old, polished, stone axe found in Canterbury but made in the Alps. Between 5,000 and 2,000BC Mesopotamia built the royal city of Ur, the Indus valley boasted the city of Harappa, and the great early civilisation of Egypt spread along the Nile. But in Britain, and most other places, life was much simpler. Neil MacGregor, Director of the British Museum, tells the story of how this beautiful jade axe may have been used and traded, and how its source was traced to the heart of Europe. (Duration: 14 mins)
