Ilyap'a

In Incan mythology, Ilyap'a ("thunder and lightning") was a very popular weather god. His holiday was on July 25. He was said to keep the Milky Way in a jug and use it to create rain.

During droughts, the Incans tied up black dogs and let them starve, hopinh Ilyap'a would send them rain out of pity. He appeared as man in shining clothes, carrying a club and stones.
