The god of eternity. He was a ghostly primordial deity who personified the meaning of time (sometimes he is confused with god Chronos). In Greek, Aion means "century". Although incorporeal, he was also portrayed as a monster with a snake body and three heads: one human (male), one bull and one lion. According to a myth, Aion and his companion, Ananke (also with a snake body), wrapped themselves around the cosmic egg and broke it to form the "sorted" Universe (earth - sky - sea).
