Μέδουσα She was beheaded by the hero Perseus, who was sent to fetch her head by King Polydectes of Seriphus. Polydectes wanted to marry Perseus’s mother. The gods were well aware of this, and Perseus received help. He received a mirrored shield from Athena, gold, winged sandals from Hermes, a sword from Hephaestus and Hades’s helm of invisibility. Since Medusa was the only one of the three Gorgons who was mortal, Perseus was able to slay her while looking at the reflection from the mirrored shield he received from Athena. During that time, Medusa was pregnant by Poseidon. When Perseus beheaded her, Pegasus, a winged horse, and Chrysaor, a giant wielding a golden sword, sprang from her body.
