Medusa is a figure from Greek mythology, best known as the most famous of the Gorgons. In the best-known version of the myth, she was mortal, had a petrifying gaze, and was killed by the hero Perseus; her severed head was later used as a protective symbol.

Medusa is usually presented as one of the three Gorgons and the most famous member of that group. Sources describe her as a monster or chthonic figure associated with petrification and danger.

Origin stories

Ancient and later retellings differ on Medusa’s origins. Some describe her as born a Gorgon, while others say she was once a beautiful woman who was transformed into a monster after an encounter involving Poseidon and Athena.

Medusa is central to the myth of Perseus, who was sent to kill her and succeeded with help from gods such as Athena and Hermes in several versions. Perseus used a reflective shield to avoid looking directly at her and cut off her head.
