""This authoritative volume has been revised throughout and expanded, with new images and accounts of the major discoveries of recent years. Updates begin with the earliest periods: one of the enduring puzzles surrounding Mexican prehistory, the origins of maize farming, has at last been solved. There are insights into the latest finds at the Olmec sites at Chiapas de Corzo and Zazacatla. The classic city of Teotihuacan continues to yield discoveries, changing the way we look at this major site. The Post-Classic Huastec people are covered in greater detail. And the unearthing of burial deposits in the center of the Aztec capital of Tenochtitlan has led to a new understanding of the history and symbolism of this hallowed area.""--Page 4 of cover.
