Medusa turned men who looked at her to stone. Thus, when Perseus set out to decapitate her, he could only do it if he didn't have to look at her. Perseus was given divine gifts that helped him. Athena, Hermes, and nymphs lent him with winged sandals, Hades' cap of invisibility, a bag for the head, and a sickle or curved sword, which Perseus used to decapitate the sleeping monster, while looking into the mirrored surface of Athena's bronze shield. Perseus gave the head of Medusa to Athena for her shield. He needed the cap of invisibility to escape from Medusa's two pursuing sisters.
