Ancient Greece is famous for its mythology. Ancient Greek myths are stories that include magic and creatures, as well as the Greek gods and goddesses. There is usually a message at the end of the story. The myths were often stories of good versus evil, with characters facing difficult obstacles.
Medusa and her two sisters were monsters called Gorgons. Medusa looked like an ugly witch with poisonous snakes instead of hair. She turned people to stone by looking them in the eye. She was eventually defeated by Perseus, who avoided looking Medusa in the eye by using his shield as a mirror to see where she was. He then slayed her with his sword.
