"Chronos (/ˈkroʊnɒs/; Greek: Χρόνος, "time," also transliterated as Khronos or Latinised as Chronus) is the personification of Time in pre-Socratic philosophy and later literature.
Chronos is a god with a serpentine shape and three heads: those of a man, a bull, and a lion. Chronos and his daughter and consort Ananke (Inevitability) circled the primal world egg in their coils and split it apart to form the ordered universe of earth, sea, and sky.
Chronos already was 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 allegory of "Father Time" wielding the harvesting scythe.
He was depicted in Greco-Roman mosaics as a man turning the Zodiac Wheel. Chronos might also be contrasted with the deity Aion as Eternal Time
Chronos is usually portrayed as an old, wise man with a long, grey beard, similar to Father Time. Some of the current English words whose etymological root is khronos/chronos include chronology, chronometer, chronic, anachronism, and chronicle."
