Was medusa a mortal gorgon

Medusa was one of the three Gorgon sisters in Greek mythology, and she is unique among them as a mortal. According to the myth, she was originally a beautiful maiden but was transformed into a Gorgon by Athena as punishment. Unlike her immortal sisters, Stheno and Euryale, Medusa's mortality made her vulnerable, ultimately leading to her demise at the hands of the hero Perseus.
