Chronos

Chronos, or Chronus, was the personification of time.

Mythology
Chronos was imagined as a serpentine god with three heads--those of a man, a bull, and a lion. He and his consort, Ananke, circled the primal world egg in their coils and split it apart to form the ordered universe of earth, sea, and sky.

Chronos was confused or identified with Cronus, possibly because of the similar names. This identification became more widespread during the Renaissance, giving rise to the allegory of "Father Time" wielding the harvesting scythe.

He was depicted in Greco-Roman mosaics as a man turning the Zodiac Wheel. Chronos, however, might also be contrasted with the deity Aion as Eternal Time.

Chronos was usually portrayed as an old, wise man with a long, gray beard, similar to Father Time.

Mythical Cosmogonies
In the Orphic cosmogony, the unaging Chronos produced Aether and Chaos and made a silvery egg in the divine Aether. It produced the god Phanes, who gave birth to the first generation of gods and is the ultimate creator of the cosmos.
