As recently as 1987, robbers discovered by far the most spectacular vestiges of the Moche people, who ruled much of Peru for the first six centuries of the Christian era. This find - a royal burial chamber shoulder-deep in gold and silver ornaments and carvings studded with jewels - has provided many powerful insights into their way of life as Nigel Davies shows. Patterns representing a condor, a killer whale and even an 80-metre monkey, visible only from the air, are etched into a bare expanse of desert at Nazca. Davies analyses and assesses the latest scholarly theories surrounding one of the world's great enigmas. He then turns to the key power centres of the 'middle period' in Huari and Tiahuanaco, the great coastal civilization of Chimor (the first for which we have written accounts), and its eventual defeat by the Incas in around 1470. Alongside the often biased conquistador chronicles, rchaeology can now illuminate the Inca imperial cult, their methods of agriculture, road-building, town-planning and settlement.
