Mesoamerican rain and fertility god, usually depicted wearing a fringed mouth-mask or a spectacle-shaped frame round his eyes, recognized this way in the art of the Aztec people of Teotihuacán. Under various names Tlaloc was worshipped by other of the Mexican tribes: Chac (Lowland Maya), Tajin (Totonacs) and Cocijo (Zapotecs). Images of Tlaloc occur in many contexts over a considerable period of time, e.g. at Copán, Monte Alban, Kaminaljuyu and Chichen Itza. During the Classic Period his image appears on pottery, wall painting, and architecture.
