This book traces the evolution of Maya civilization through the Pre-Columbian era, a span of some 2,500 years from the origins of complex society within Mesoamerica to the end of the Pre-Columbian world with the Spanish Conquest in the 16th century. The sixth edition presents new archaeological evidence and historical studies and offers the most extensive revisions of this classic work to date. The result is the most through and incisive study of the origins and development of ancient Maya civilization ever published.
