The homelands of the ancient Maya spanned a vast region that today includes central and south Mexico, Belize, Guatemala, and the western portions of Honduras and El Salvador. Maya peoples expressed their cultural practices and belief systems through distinct artistic styles and a hieroglyphic writing system. Over time, many pieces of pottery have been removed from ancient Maya sites without archaeological excavation. Even though knowledge of where vessels came from is lost, they can nevertheless offer many insights about Maya artistic production.
