I will go off and kill Medusa and bring back her head!

He tells him to go to the Gray Women so they can tell him where the nymphs' abode is which is where the item he needed was. Hermes then gave Perseus a sword which could not be broken by the Gorgon's scales. Then, Athena gives Perseus her shield so he will be able to look into that to see Medusa and not be turned into stone. The Gray Women tell him the directions and he finds winged sandals,a magic wallet, and a cap that made the wearer invisible awaiting him.
