Chronos

In Greek mythology, Chronos (Greek: Χρονος, Khronos, "time"), also known as Aeon (Greek: Αιων, Aion, "age" or "eternity") and Porus (Greek: Πορος, Poros, "contrivance" or "passage"), was the primordial god of time, particularly linear and chronological time. He is typically depicted with the Zodiac Wheel and as an old man with a long, gray beard. He is contrasted with Aion, the deity of eternal time.

Mythology
In the Orphic tradition, Chronos was born from "earth and water" and sired Aether and Chaos, the two atmospheres, as well as the primal world egg, all with his consort, Ananke. From the egg came Phanes, who gave birth to the first generation of gods.

Chronos was also envisioned as a serpentine deity wrapped around the primal world egg. Along with Ananke, they split the world egg into the earth, heaven, and the sea.
