Medusa's power may have begun as a ritual mask, not a monster
Of the three Gorgon sisters, only Medusa could die. Perseus took her head by watching her reflection in a polished shield, and even severed it kept turning people to stone. One classical scholar argued the whole legend grew backwards from a terrifying mask whose ritual purpose had been forgotten.
Medusa, whose name means guardian or protectress, was one of the Gorgons, usually pictured with living snakes for hair and a gaze that petrified. Hesiod and Apollodorus made her and her immortal sisters Stheno and Euryale daughters of the sea-god Phorcys and his sister Ceto, while Hyginus named a father called Gorgon. Writers disagreed on where they lived: Hesiod and Aeschylus spoke of Sarpedon near Cisthene, while Herodotus and Dionysius Scytobrachion placed them in Libya.
King Polydectes of Seriphus sent Perseus to fetch her head because he wanted to marry the hero's mother. The gods equipped him: a mirrored shield from Athena, winged golden sandals from Hermes, a sword from Hephaestus and the helm of invisibility belonging to Hades. Medusa was carrying Poseidon's child, and when she was beheaded the winged horse Pegasus and the giant Chrysaor sprang out. Perseus later turned Polydectes to stone and gave the head to Athena for her aegis.
Her blood was said to have seeded wonders. In Ovid, Perseus petrified the Titan Atlas; drops from the head supposedly became Red Sea coral when he set it down on seaweed in Ethiopia, where he rescued and married Andromeda. Other poets said Saharan vipers and the two-headed Amphisbaena grew from her spilt blood. Her face, the Gorgoneion, served in antiquity as a charm against evil. Jane Ellen Harrison saw that object as the true origin, a ritual mask later given a body and a story.
Her looks changed over time. Early art made the Gorgons grotesque, but by the fifth century BC artists showed Medusa as beautiful, and Pindar wrote of her fair cheeks in 490 BC. Polygnotus painted her asleep and lovely as Perseus struck, an unheroic scene that may invite pity or mock the hero. Ovid's late version makes her a maiden punished with snakes by Minerva after Neptune took her in the goddess's temple, a detail no earlier source mentions.
