Chronos

[1] Chronos is frequently confused with, or perhaps consciously identified with, the Titan, Cronus, in antiquity, due to the similarity in names.

[2] The identification became more widespread during the Renaissance, giving rise to the iconography of Father Time wielding the harvesting scythe.

[5] He is usually portrayed as an old callous man with a thick grey beard, personifying the destructive and stifling aspects of time.

[8] In the Orphic tradition, the unaging Chronos was "engendered" by "earth and water", and produced Aether, Chaos, and an egg.

Pherecydes of Syros in his lost Heptamychos ("The seven recesses"), around 6th century BC, claimed that there were three eternal principles: Chronos, Zas (Zeus) and Chthonie (the chthonic).
