Tlaloc

Tláloc is the god of rain in Aztec religion. He was also a deity of earthly fertility and water, and worshipped as a giver of life and sustenance; many rituals and sacrifices predicated upon these aspects were held in his name. He was feared—albeit not as a malicious figure—for his power over hail, thunder, lightning, and rain. He is also associated with caves, springs, and mountains, most specifically the sacred mountain where he was believed to reside. Cerro Tláloc is very important in understanding how rituals surrounding this deity played out. Tláloc appears to be one of the oldest and most universal figures of worship in ancient Mexico.
