In Greek mythology, Medusa was one of the three Gorgons, generally described as a winged woman with living snakes in place of hair, whose appearance was so hideous that anyone who looked upon her was turned to stone. Of the three Gorgon sisters — Medusa, Stheno, and Euryale, the daughters of the sea-deities Phorcys and Ceto — she alone was mortal. She was beheaded by the hero Perseus, and from her body sprang the winged horse Pegasus and the giant Chrysaor, her children by Poseidon. Perseus used her severed head, which kept its petrifying power, as a weapon before giving it to Athena, who set it upon her aegis.

I.Mythology
The three Gorgons were the offspring of the sea-god Phorcys and his sister Ceto, according to Hesiod and Apollodorus, though Hyginus instead names their father as Gorgon. They shared a common ancestry with other monstrous sisters, including the grey Graeae. Of the three Gorgons — Medusa, Stheno, and Euryale — only Medusa was mortal.
King Polydectes of Seriphus sent Perseus to fetch Medusa's head, hoping to remove him so that he might marry Perseus's mother. The gods were aware of this, and Perseus received help: a mirrored shield from Athena, winged sandals from Hermes, a sword from Hephaestus, and Hades' helm of invisibility. Because Medusa alone among the Gorgons was mortal, Perseus was able to slay her, doing so while looking only at her reflection in the mirrored shield to avoid being turned to stone.
At the moment of her death Medusa was pregnant by Poseidon, and from her body sprang Pegasus, a winged horse, and Chrysaor, a giant wielding a golden sword. Perseus carried away the head, which retained its power to petrify onlookers, and ultimately gave it to Athena, who placed it on her shield, the aegis.
Later traditions elaborated on the aftermath. According to Ovid, the corals of the Red Sea were formed from Medusa's blood spilled onto seaweed, and the venomous vipers of the Sahara grew from drops of her blood scattered across the desert.
Ancient vase-painters depicted Medusa as wholly monstrous, but sculptors and vase-painters of the fifth century BC began to envisage her as beautiful as well as terrifying. In a late retelling by Ovid, Medusa was originally a beautiful maiden; when Neptune (Poseidon) mated with her in the temple of Minerva (Athena), the offended goddess punished Medusa by transforming her lovely hair into serpents.
II.Modern interpretations
Historical: Some early scholars read the myth as a quasi-historical memory of religious and political change. Joseph Campbell argued that Perseus's beheading of Medusa signified that the Hellenes overran the goddess's chief shrines and stripped her priestesses of their Gorgon masks.
Psychoanalysis: In a 1940 note, Sigmund Freud equated decapitation with castration, writing that the terror of Medusa is a terror of castration linked to the sight of something, and connecting the snake-haired head to primal castration anxiety. He also observed that there are no recorded instances of Medusa turning a woman to stone.
Feminism: Twentieth-century feminist writers reassessed Medusa in literature and culture, often treating her as a symbol of female rage. The 1978 feminist journal Women: A Journal of Liberation used Medusa imagery as a guide through terror toward the sources of women's power. Hélène Cixous's essay "The Laugh of the Medusa" argued that men's retellings made her monstrous, insisting that one need only look at the Medusa straight on to see that she is not deadly but beautiful and laughing. Contemporary artists such as Judy Takács have reframed the myth as a rape-victim narrative, and scholars have examined the use of Medusa as a logo by the fashion company Versace.
Nihilism: Medusa has also been read as a figure of scientific determinism and nihilism, symbolizing an unavoidable truth. Jack London employed her in this sense in The Mutiny of the Elsinore, invoking a "Medusa-Truth."
III.Art
Medusa has been a recurring subject in Western art, depicted by masters including Leonardo da Vinci, Benvenuto Cellini, Caravaggio, and Bernini, and later by artists such as Salvador Dalí and Auguste Rodin. The contemporary sculptor Luciano Garbati portrayed her in 2008 clutching the severed head of Perseus, inverting the traditional narrative of victor and victim.
Flags and emblems: The head of Medusa appears on the flag and emblem of Sicily, together with the three-legged trinacria, implying the protection of the goddess Athena, who wore the Gorgon's likeness on her aegis.
IV.Science
Medusa is honored in more than sixty scientific names across zoology and biology, including such genera as Medusaceratops, Stygiomedusa, and Medusablennius.
