Book excerpt: This book takes a dramatically original approach to the history of humanity, using objects which previous civilisations have left behind them, often accidentally, as prisms through which we can explore past worlds and the lives of the men and women who lived in them. The book's range is enormous. It begins with one of the earliest surviving objects made by human hands, a chopping tool from the Olduvai gorge in Africa, and ends with an object from the 21st century which represents the world we live in today. Neil MacGregor's aim is not simply to describe these remarkable things, but to show us their significance - how a stone pillar tells us about a great Indian emperor preaching tolerance to his people, how Spanish pieces of eight tell us about the beginning of a global currency or how an early Victorian tea-set tells us about the impact of empire. Each chapter immerses the reader in a past civilisation accompanied by an exceptionally well-informed guide. Seen through this lens, history is a kaleidoscope - shifting, interconnected, constantly surprising, and shaping our world today in ways that most of us have never imagined. An intellectual and visual feast, it is one of the most engrossing and unusual history books published in years.
