Neil MacGregor concludes the first week of the second part of his global history as told through objects from the British Museum. This week he has been exploring the lives and methods of powerful rulers around the world about 2000 years ago, from Alexander the Great in Egypt to Asoka in India. Today he introduces us to the great Roman emperor Augustus, whose powerful, God-like status is brilliantly enshrined in a larger than life bronze head with striking eyes. Neil MacGregor describes how Augustus dramatically enlarged the Roman Empire, establishing his image as one of its most familiar objects. The historian Susan Walker and the politician Boris Johnson help explain the power and methodology of Augustus.
