Hermes and Perseus then collected the three magical gifts from the North nymphs. The nymphs gave him a pair of winged sandals, a magic wallet, and a cap that had the power to turn him invisible. Then Perseus and Hermes flew to the island of the Gorgons.
The Road Back
Perseus arrived at the island of the Gorgons. He hovered over the Gorgons with his sword ready then he stared into the shield and struck off Medusa's head. Perseus then stuffed her head into the magic wallet. Hermes mission was over so he left Perseus.
Now that Perseus had Medusa's head he was ready to go home with the award. He traveled back to the island to prove to Polydectes that he was brave enough to get the wedding gift. Perseus also won another reward, he saved his mother from marrying Polydectes.
Return with the Elixir
On the way back Perseus slew a dangerous sea monster that was going to devour Andromeda. For which, she agreed to be Perseus's bride. Perseus brought the head to Polydectes, Who didn't believe that Perseus killed Medusa and called him a liar, so Perseus show Polydectes the head and turned to stone.
King Dictys became the ruler of the island. Perseus went to Argos, where King Acrisius was attending games. Perseus wanted to take part in the games and threw a discus. The discus was taken by the wind and hit King Acrisius, which killed him.
Delphi's oracle that said Danaé's son would kill king came true. Danaé does not have to marry Polydectes, and Perseus doesn't have to defend his mother from marrying Polydectes anymore.
