Source Verification: Proteus
Every claim below is either what a named ancient source attests, in its own line or section, or a point where the sources themselves disagree.
What the Sources Attest
Who is Proteus, and where is he from?
An immortal sea god Homer's Odyssey places in Egypt, described as "the servant of Poseidon" with unerring knowledge of the sea and of every traveler's fate. He tends Poseidon's seals near the island of Pharos and is the father of the minor goddess Eidothea.
Source: Homer, Odyssey 4.349-370
How does Menelaus force Proteus to speak?
By ambush and endurance. Disguised in sealskins on Eidothea's advice, Menelaus and three companions lie hidden among Proteus's own seals until he comes ashore to sleep, then seize him. He cycles through the shapes of a lion, a serpent, a leopard, a boar, running water, and a tree trying to break free, but the men never release their grip until he gives up and answers.
Source: Homer, Odyssey 4.400-424
What does Proteus predict about Menelaus's own fate?
That he will not die in Argos, but will be carried by the immortals to the Elysian plain at the edge of the world, a reward Proteus explains is granted specifically because Menelaus is married to Helen and therefore counted as Zeus's own son-in-law.
Source: Homer, Odyssey 4.561-570
What does Proteus reveal about Odysseus?
That Odysseus is alive but trapped, held on Calypso's island against his will and weeping for a way home, unable to leave because he has no ship or crew left to sail with. This is the first news in the Odyssey's own story of where Odysseus actually is.
Source: Homer, Odyssey 4.555-560
Is Proteus the same figure as Nereus, the other shape-shifting Old Man of the Sea?
No. Homer ties Proteus to Egypt and to Poseidon's service, while Hesiod makes Nereus a son of Pontus and Gaia with no connection to Egypt at all; their genealogies never meet. But both are called "the old man of the sea," and both stories share the same core structure, a hero who must physically hold a shape-shifting god through every transformation to win a truth, almost certainly one folk-tale pattern used twice rather than one figure under two names.
Source: Homer, Odyssey 4.349-370
Is Proteus also said to be an Egyptian king rather than a sea god?
In a separate, later tradition, yes. Apollodorus records that some accounts place the real Helen at the court of a King Proteus of Egypt during the Trojan War, with only a cloud phantom of her sent to Troy, an entirely different role for the name than Homer's shape-shifting sea god, and one this site treats as a distinct strand of tradition rather than a contradiction to resolve.

Where Accounts Differ
- whether Proteus and Nereus are the same figure
- Proteus's parallel with Nereus (shared epithet, shared forced-transformation-prophecy structure) is treated here as a real, source-attested pattern, not an identification of the two figures, which no ancient source makes.
