According to the Inca creation myth, Ataguchu is a god of creation. He instructed Piguerao and Apocatequil on how to get out of Pacari (the Cave of Refuge) to which they had retreated during some great world disaster. Piguerao and Apocatequil are twin sons of Guamansuri (the first mortal), and Apocatequil was the chief priest of the moon god and also consider a god himself, the god of lightning. Respect for these twins led the Incas to view all twin births as sacred.
Ataguju, a god of the Huamachuco Indians of Peru, is a variation of Ataguchu. According to their myths, Ataguju appeared in a triad with Sugadcavra (Sugudcavra) and Acumgavrad, though he was their superior and creator. He also created the first mortal, Guamansuri, the father of Apocatequil and Piguero.
