The rich findings of recent exploration and research are incorporated in this completely revised and greatly expanded edition of the standard work on the New World's most brilliant native civilization - that of the Maya people of northern Central America and southern Mexico. New field discoveries, new technical advances, new successes in the decipherment of Maya writing, and new theoretical perspectives on the Maya past have made necessary this present edition. It contains some 500 photographs, line drawings, maps, and site maps - about one fourth of which are new.
