In Greek mythology, Proteus (; , ) is an early prophetic sea god or god of rivers and oceanic bodies of water, one of several deities whom Homer calls the "Old Man of the Sea" (hálios gérôn). Some who ascribe a specific domain to Proteus call him the god of "elusive sea change", which suggests the constantly changing nature of the sea or the liquid quality of water. He can foretell the future, but, in a mytheme familiar to several cultures, will change his shape to avoid doing so; he answers only to those who are capable of capturing him.

Cabeiro, mother of the Cabeiri and the three Cabeirian nymphs by Hephaestus, was also called the daughter of Proteus.

Mythology Proteus, prophetic sea-god According to Homer (Odyssey iv: 355), the sandy island of Pharos situated off the coast of the Nile Delta was the home of Proteus, the oracular Old Man of the Sea and herdsman of the sea-beasts.
