No, Medusa is from Greek mythology.
The theme of the story is, " Don't be sure until you're positive
No
Medusa is the monster slain by Perseus, the oldest of the Greek heroes.
Medusa was not a hero- her actions were motivated by the fact that she was a monster.
The story is about him and his mother, he is trying to get the gorgan's head, medusa.
If you're talking about Perseus and the Gorgon's head, than it's Perseus. If you're talking about the story about who Medusa got her snake hair, then it's just Poseidon, Medusa and Athena.
Well, the story goes, that when Persues had slain Medusa, Pegasus sprang out of Medusa's severed neck. It must have something to do with that.
I should probably put the story here, or else my answer won't make sense. The story of Medusa: Medusa used to be a beautiful girl. She was a girlfriend of Poseidon, the God of The Seas. One day, Medusa and Poseidon were making out on the floor of one of Athena's temples. Athena realised what was happening, and got mad. She turned Medusa's lovely curls into writhing little snakes, and put a curse on Medusa: whoever looked at Medusa in the eyes will turn into stone. Therefore, Athena turned Medusa into a Gorgon. The explanation: um...never mess with a goddess??
Stheno and Euryale didn't become like Medusa. Medusa became like them. Before Medusa had become a woman with snakes as hair she was mortal. Her sisters were not. There are two versions of Medusa's story. One was that Medusa became cursed because she slept with Poseidon in Athena's temple. The other story was that Medusa had sworn celibacy to Athena, but forgot those vows and married Poseidon.
Yes, she never existed
