In Aztec mythology, Atlahua, Ahtlahua, Atlahoa, Atlavâ or Atlaua was a water God, fisherman and archer. There were said to be at least four ancient Aztec temples at which he was worshiped, the tallest supposedly being over 200 feet tall. The Aztecs prayed to him when there were deaths in water, such as when Hernando Cortez conquered Tenochtitlan, and the lake was said to be "floating with heads and corpses".
