Medusa was originally a beautiful woman, but was punished by the goddess Athena by transforming her into a monster with snakes for hair. Anyone who made eye contact with Medusa would immediately turn to stone. Perseus was sent by the king Polydectes to retrieve Medusa's head, knowing it was a deadly mission. With help from the gods, Perseus obtained tools to slay Medusa without looking at her directly. He found her sleeping, cut off her head using Athena's reflective shield, and returned successfully with the head to turn Polydectes to stone.
