Danaë is the beautiful young daughter of King Acrisius. King Acrisius is told by the Oracle of Delphi that her son would one day kill him, and so he traps Danaë in a Bronze home underground. Zeus "visits" Danaë, who is sealed in a chest with her baby , which took them to Dictys. Dictys beomes a father figure to Perseus.
Polydectes, the cruel brother of Dictys, doesn't want to have Perseus when he married Danaë. He manages to make Perseus swear to bring him the head of a Gorgon.
Athena and Hermes help Perseus by giving him a bronze shield, so he may gaze upon Medusa without being turned to stone, and a sword that cannot be bent by their scales. They also tell him where the Gray Sisters live.
The only people who knew the location of the nymphs of the North were the three Grey Women, who shared an eye. Perseus threatened the three by capturing their eye, and they gave him the location.
Perseus and Hermes are welcomed by the Hyperboreans, who tell them the location of the Gorgons and give them three gifts. They were given a magic wallet, winged shoes, and a cap of invisibility.
Perseus beheads Medusa and puts her head into his magic wallet.
