The four rain deities in Maya mythology are called the Chacs, also spelled Chaacs or Chacs.
Rather than being only one god, Chaac could be understood as both a single rain deity and a group of directional rain beings. The four Chacs were associated with the cardinal directions, and each direction had its own color: red for east, white for north, black for west, and yellow for south. Green was associated with the center.
Chaac was linked to rain, thunder, lightning, and agricultural fertility. Maya imagery often shows him with a long, pendulous nose, reptilian features, and a lightning axe. In myth, the axe could split open clouds or help release the maize hidden inside a mountain, connecting storms directly with the survival of crops.
The Chacs should not be confused with the Bacabs or Pauahtuns. Colonial descriptions sometimes grouped these figures together because all were associated with directions, weather, or cosmic support, but they are distinct names and concepts. Modern Yucatec Maya communities also recognize multiple aspects of rain and clouds.
