Proteus (Greek)

Proteus (/ˈproʊtiəs, -tjuːs/;[1] Ancient Greek: Πρωτεύς) is an early sea-god or god of rivers and oceanic bodies of water, one of several deities whom Homer calls the "Old Man of the Sea".[2] Some who ascribe to him a specific domain call him the god of "elusive sea change", which suggests the constantly changing nature of the sea or the liquid quality of water in general. He can foretell the future, but, in a mytheme familiar to several cultures, will change his shape to avoid having to; he will answer only to someone who is capable of capturing the beast. From this feature of Proteus comes the adjective protean, with the general meaning of "versatile", "mutable", "capable of assuming many forms". "Protean" has positive connotations of flexibility, versatility and adaptability.

According to Homer (Odyssey iv:412), 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. In the Odyssey, Menelaus relates to Telemachus that he had been becalmed here on his journey home from the Trojan War. He learned from Proteus' daughter Eidothea ("the very image of the Goddess"), that if he could capture her father, he could force him to reveal which of the gods he had offended and how he could propitiate them and return home. Proteus emerged from the sea to sleep among his colony of seals, but Menelaus was successful in holding him, though Proteus took the forms of a lion, a serpent, a leopard, a pig, even of water or a tree. Proteus then answered truthfully, further informing Menelaus that his brother Agamemnon had been murdered on his return home, that Ajax the Lesser had been shipwrecked and killed, and that Odysseus was stranded on Calypso's Isle Ogygia.

he children of Proteus, besides Eidothea, include Polygonus and Telegonus, who both challenged Heracles at the behest of Hera and were killed, one of Heracles' many successful encounters with representatives of the pre-Olympian world order.

Another Proteus occurs in Greek myth as one of the fifty sons of King Aegyptus. There are also legends concerning Apollonius of Tyana that say Proteus incarnated himself as the 1st century philosopher. These legends are mentioned in the 3rd century biographical work Life of Apollonius of Tyana.

Proteus of Egypt
In the Odyssey (iv.430ff) Menelaus wrestles with "Proteus of Egypt, the immortal old man of the sea who never lies, who sounds the deep in all its depths, Poseidon's servant" (Robert Fagles's translation). Proteus of Egypt is mentioned in an alternative version of the story of Helen of Troy in the tragedy Helen of Euripides (produced in 412 BC). The often unconventional playwright introduces a "real" Helen and a "phantom" Helen (who caused the Trojan War), and gives a backstory that makes the father of his character Theoclymenus, Proteus, a king in Egypt who had been wed to a Nereid Psamathe. In keeping with one of his themes in Helen, Euripides mentions in passing Eido ("image"), a daughter of the king and therefore sister of Theoclymenus who underwent a name-change after her adolescence and became "Theonoë," "god-minded," since she was as it turned out capable of foreseeing the future--as such, she is a prophet who appears as a crucial character in the play. The play's king Proteus is already dead at the start of the action, and his tomb is present onstage. It appears that he is only marginally related to the "Old Man of the Sea"[6] and should not be confused with the sea god Proteus, although it is tempting to see Euripides as playing a complex literary game with the sea god's history--both Proteuses, for example, are protectors of the house of Menelaus, both are connected with the sea, both dwell in Egypt, and both are "grandfatherly" or "ancient" figures.

At Pharos a king of Egypt named Proteus welcomed the young god Dionysus in his wanderings.[7] In Hellenistic times, Pharos was the site of the Lighthouse of Alexandria, one of the seven wonders of the ancient world.

Etymology
Proteus' name suggests the "first" (from Greek "πρῶτος" - protos, "first"), as protogonos (πρωτόγονος) is the "primordial" or the "firstborn". It is not certain to what this refers, but in myths where he is the son of Poseidon, it possibly refers to his being Poseidon's eldest son, older than Poseidon's other son, the sea-god Triton. The first attestation of the name, although it is not certain whether it refers to the god or just a person, is in Mycenaean Greek; the attested form, in Linear B, is 𐀡𐀫𐀳𐀄, po-ro-te-u.
