The Gorgons were all sisters born to Phorcys and Ceto and they were called Medusa, Euryale, and Stheno. (Medusa was mortal while her sisters were immortal).
Medusa was a formidable enemy, with her hideous appearance she was able to turn any onlooker into stone. In some myths, Medusa was born a monster like her sisters, but she was the only Gorgon to possess snake locks, because they were a punishment from Athena as the once beautiful mortal Medusa was punished by Athena with a hideous appearance and loathsome snakes for hair for having been raped in Athena’s temple by Poseidon.
As for her death it is said that Perseus, with the aid of divine gifts, found the Gorgons’ cave and slayed Medusa by beheading her. After Perseus had finished with the Gorgon’s head, he gave it to Athena, who adorned her shield and breastplate with it to instil fear in her enemies.
Euryale was the second eldest one of the Gorgons, she had brass hands, sharp fangs, and hair of living, venomous snakes. She also had the ability to turn someone into stone with just a gaze. In many stories, Euryale is known for her bellowing cries, especially in the tale of Medusa’s death at Perseus’ hands.
Stheno was the eldest of the Gorgons, she was also a vicious female monster with brass hands, sharp fangs and “hair” made of living venomous snakes.
Stheno was known to be the most independent and ferocious, she had killed more men than both of her sisters combined according to ancient myths. Stheno is depicted as a thin gorgon monster with red snakes curling around her head instead of hair.
