Chronos is the personification of time in Greek mythology. He was considered to have the shape of a three-headed serpent. The heads were those of a man, a bull and a lion. Along with his daughter Ananke, the goddess of inevitability who was also in the form of a snake, he revolved around the primordial world egg, until they split it apart to form the earth, the sea and the sky. According to the Orphic cult, Chronos gave birth to Aether and Chaos, and created a silver egg in Aether. Out of the egg eclosed the gods Phanes and Hydrus, who later gave birth to the first gods and the universe. Sometimes, Chronos was confused with the Titan god Cronus by mistake, or conflated with him on purpose.
