Tlaloc (Tlá-loch) was the Aztec rain deity and one of the most ancient and widespread deities of all Mesoamerica. Tlaloc was thought to live on the top of the mountains, especially the ones always covered by clouds; and from there he sent the much needed rains. The rain god was a pan-Mesoamerican deity, whose origins can be traced back to Teotihuacan and the Olmec. The rain deity was called Chaac by the ancient Maya and Cocijo by the Zapotec of Oaxaca.
