Proteus was another "Old Man of the Sea," a son of Poseidon (in some accounts) or an older sea-divinity in his own right (in others), who herded Poseidon's seal-flocks on the island of Pharos near the mouth of the Nile. Like Nereus, he was prophetic; like Nereus, he resisted interrogation by shape-shifting; and the most famous Proteus-narrative is that of Menelaus, who, becalmed in Egypt on the way home from Troy, was advised by Proteus's daughter Eidothea to seize her father at noon (when he came up from the sea to nap among his seals) and to hold him fast through all his transformations. Menelaus did so, holding through fire, water, lion, serpent, leopard, boar, and finally tree, until Proteus relented and gave him the prophecies he needed for his return. The story is told at length in the fourth book of the Odyssey. From Proteus the English tongue derived the adjective protean for that which changes form bewilderingly.

Curator’s note
What the sources say, and what later tradition added. The sources for this bay
Homer, Odyssey 4.351–570 (the Menelaus encounter, the principal text); Vergil, Georgics 4.387–528 (a later and elaborated version). A different Proteus appears in Herodotus 2.112–120 as an Egyptian king (perhaps reflecting some Greek confusion or syncretism with an Egyptian figure); the divine Proteus and the Egyptian king Proteus are not consistently distinguished in the tradition.
