Chronos

Chronos (Χρονος), also known as Aeon (Αιων) and Porus (Πορος), was the Greek primordial god of time. He was only mentioned in the Orphic cosmogony where he was said to be a child of Hydros and Gaea and the husband of Ananke. By Ananke, he was said to be the father of Chaos, Aether, and Erebus. However, the Orphic cosmogony was not the usual belief. He was usually depicted as a serpentine deity with three heads (a human, a bull, and a lion) wrapped around the world egg with his wife.
