In Mixtec mythology, Dzahui or Dzavui was the god of rain. Child sacrifices were performed for Dzahui on the tops of hills during times of drought, sickness, and at harvest time.

In Mixtec codices, Dzahui exhibits the blue or green rain goggle mask also seen on the central Mexican deity Tlaloc. He possesses exposed teeth incisors and longer, somewhat curled jaguar canine teeth emerging from curled lips. Occasionally, depictions of Dzahui depict the god with a blue or green protrusion, emerging from his nose.
