Perseus

In Greek mythology, Perseus (US: /ˈpɜːr.si.əs/ ^ⓘ, UK: /ˈpɜː.sjuːs/; Greek: Περσεύς, translit. Perseús) is the legendary founder of the Perseid dynasty. He was, alongside Cadmus and Bellerophon, the greatest Greek hero and slayer of monsters before the days of Heracles. He beheaded the Gorgon Medusa for Polydectes and saved Andromeda from the sea monster Cetus. He was a demigod, being the son of Zeus and the mortal Danaë, as well as the half-brother and great-grandfather of Heracles (as they were both children of Zeus, and Heracles's mother was Perseus's granddaughter).

Because of the obscurity of the name "Perseus" and the legendary character of its bearer, most etymologists presume that it might be pre-Greek; however, the name of Perseus's native city was Greek and so were the names of his wife and relatives. There is some idea that it descended into Greek from the Proto-Indo-European language. In that regard Graves proposed the only Greek derivation available: Perseus might be from the Greek verb pérthein (πέρθειν) "to waste, ravage, sack, destroy", some form of which is familiar in Homeric epithets. According to Carl Buck, the -eus suffix is typically used to form an agent noun, in this case from the aorist stem, pers-. Pers-eus therefore is a "sacker [of cities]"; that is, a soldier by occupation, a fitting name for the first Mycenaean warrior.

The further origin of perth- is more obscure. Hofmann lists the possible root as *bher-, from which Latin ferio, "strike". This corresponds to Pokorny's *bher-(3), "scrape, cut". Ordinarily *bh- descends to Greek as ph-. This difficulty can be overcome by presuming a dissimilation from the -th- in pérthein, which the Greeks would have preferred from a putative *phérthein. Graves carries the meaning still further, to the Perse- in Persephone, goddess of death. Ventris & Chadwick speculate about a Mycenaean goddess pe-re-*82 (Linear B: 𐀟𐀩𐁚), attested on tablet PY Tn 316, and tentatively reconstructed as *Preswa.

A Greek folk etymology connected Perseus to the name of the Persian people, whom they called the Pérsai (from Old Persian Pārsa "Persia, a Persian"). However, the native name of the Persians – Pārsa in Persian – has always been pronounced with an -a-. Herodotus recounts this story, devising a foreign son of Andromeda and Perseus, Perses, from whom the Persians took the name. Apparently the Persians also knew that story, as Xerxes tried to use it to suborn the Argives during his invasion of Greece, but ultimately failed to do so.

King Acrisius of Argos had only one child, a daughter named Danaë. Disappointed by not having a male heir, Acrisius consulted the Oracle at Delphi, who warned him that he would one day be killed by his own grandson. To keep Danaë childless, Acrisius imprisoned her in a room atop a bronze tower in the courtyard of his palace: This mytheme is also connected to Ares, Oenopion, Eurystheus, and others. Zeus came to her in the form of a shower of gold, and fathered her child. Soon after, their child, a son, was born; Perseus. "Perseus Eurymedon, for his mother gave him this name as well".

Fearful for his future, but unwilling to provoke the wrath of the gods and the Erinyes by killing the offspring of Zeus and his daughter, Acrisius cast the two into the sea in a wooden chest. Danaë's fearful prayer, made while afloat in the darkness, has been expressed by the poet Simonides of Ceos. The mother and child were washed ashore on the island of Seriphos, where they were taken in by the fisherman Dictys ("fishing net"), who raised the boy to manhood. The brother of Dictys was Polydectes ("he who receives/welcomes many"), the king of the island.

When Perseus was growing up on the island of Seriphus, Polydectes came to lust for the beautiful Danaë. Perseus believed Polydectes was less than honorable, and protected his mother from him; then Polydectes plotted to send Perseus away in disgrace. He held a large banquet where each guest was expected to bring a gift. Polydectes requested that the guests bring horses, under the pretense that he was collecting contributions for the hand of Hippodamia, daughter of Oinomaos. Perseus had no horse to give, so he asked Polydectes to name the gift; he would not refuse it. Polydectes held Perseus to his rash promise and demanded the snake-haired Medusa's head.

Medusa and her two immortal elder sisters, Stheno and Euryale, were Gorgons, monsters with snakes for hair, sharp fangs and claws, wings of gold, and gazes that turned people to stone.
