Chaac

Chaac (also spelled Chac or, in Classic Mayan, Chaahk [t͡ʃaːhk]) is the name of the Maya rain deity. With his lightning axe, Chaac strikes the clouds and produces thunder and rain. Chaac corresponds to Tlaloc among the Aztecs.

Rain deities and rain makers

Like other Maya gods, Chaac is both one and manifold. Four Chaacs are based in the cardinal directions and wear the directional colors. In 16th-century Yucatán, the directional Chaac of the east was called Chac Xib Chaac 'Red Man Chaac', only the colors being varied for the three other ones.

Contemporary Yucatec Maya farmers distinguish many more aspects of the rain and the clouds and personify them as different, hierarchically-ordered rain deities. The Chorti Maya have preserved important folklore regarding the process of rain-making, which involved rain deities striking rain-carrying snakes with their axes.

The rain deities had their human counterparts. In the traditional Mayan (and Mesoamerican) community, one of the most important functions was that of rain maker, which presupposed an intimate acquaintance with (and thus, initiation by) the rain deities, and a knowledge of their places and movements. According to a Late-Postclassic Yucatec tradition, Chac Xib Chaac (the rain deity of the east) was the title of a king of Chichen Itza, and similar titles were bestowed upon Classic rulers as well (see below).
