The ancient deity associated with the passage of time, often depicted with a scythe, is Chronos. He is personified as time itself in ancient mythology, symbolizing the relentless and cyclical nature of time. Unlike the Titan Kairos, who represents opportune moments, Chronos signifies the inexorable progression of time. His visual associations, such as the scythe or hourglass, are icons of the inevitability of time and its impact on mortality and existence itself within various mythological frameworks.
