Chronos

In Greek mythology, Chronos in pre-Socratic philosophical works is said to be the personification of time. His name in Modern Greek also means "year" and is alternatively spelled Chronus (Latin spelling).

Chronos was imagined as an incorporeal god. Serpentine in form, with three heads—that of a man, a bull, and a lion. He and his consort, serpentine Ananke (Inevitability), circled the primal world-egg in their coils and split it apart to form the ordered universe of earth, sea and sky. He is not to be confused with the Titan Cronus.

He was depicted in Greco-Roman mosaics as a man turning the Zodiac Wheel. Often the figure is named Aeon (Eternal Time), a common alternate name for the god.

Chronos is usually portrayed through an old, wise man with a long, gray beard, such as "Father Time". Some of the current English words whose etymological root is khronos/chronos include chronology, chronic, anachronism, and chronicle.
