Itzamná, (Mayan: “Iguana House”) principal pre-Columbian Mayan deity, ruler of heaven, day, and night. He frequently appeared as four gods called Itzamnás, who encased the world. Like some of the other Mesoamerican deities, the Itzamnás were associated with the points of the compass and their colours—east, red; north, white; west, black; and south, yellow.
