How did the ancient Greeks believe in Medusa?

The ancient Greeks viewed Medusa as one of the three Gorgon sisters, known for her hair of snakes and her ability to turn anyone who gazed upon her into stone. She was often seen as a symbol of danger and protection, embodying both fear and fascination. In mythology, Medusa was originally a beautiful maiden who was transformed into a monster as punishment by Athena. Despite her terrifying appearance, she also served as a protective figure, with her image commonly used on shields and amulets to ward off evil.
