Chronos

(Greek: Χρόνος, meaning, "time"), also spelled Khronos or Chronus, is the personification of time in pre-Socratic philosophy and later literature. Chronos is frequently confused with, or perhaps consciously identified with, the Titan Cronus in antiquity due to the similarity in names. The identification became more widespread during the Renaissance, giving rise to the iconography of Father Time wielding the harvesting scythe. Greco-Roman mosaics depicted Chronos as a man turning the zodiac wheel. He is comparable to the deity Aion as a symbol of cyclical time. In the Orphic tradition, the unaging Chronos was "engendered" by "earth and water", and produced Aether, Chaos, and an egg. The egg produced the hermaphroditic god Phanes who gave birth to the first generation of gods and is the ultimate creator of the cosmos. He is usually portrayed as an old wise man with a thick grey beard.
