Masson1 lassic Period Maya society (A.D. ∼250–850) is almost as well C known for its collapse as for its tremendous accomplishments in hieroglyphic writing, monumental art, and architecture and an extensive, populous network of cities and towns that crossed the terrain of parts of four modern nations (Mexico, Guatemala, Belize, and Hon- duras). Indeed, interest in the political and demographic collapse of this civilization around the 9th century A.D. is inextricably linked to its earlier majesty, and ancient Maya culture has evoked romantic interest about lost cities in the jungle since the early 19th century explorations of Stephens and Catherwood (1).
