Chronos (also transliterated as Khronos or Latinised as Chronus) is the personification of Time in pre-Socratic philosophy and later literature. Chronos governed linear, chronological time. The other Greek word for time is kairos, meaning the indeterminate moment that is right for something to occur.
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 (see aeon). Chronos is usually portrayed as an old, wise man with a long, grey beard, similar to Father Time.
