Danae's father was told by an oracle that his grandson would be the cause of his death. Her father kept her underground, in Argos Greece so she could never have a child. Zeus found Danae underground and they had a baby boy, named Perseus. When Danae's father found out she had a child he sent her and her child across the ocean in a box, and they washed up on an island, where Perseus grew up.
Meeting with a Mentor
The ruler of the island was Polydectes, who fell in love with Danae. Perseus wanted to protect his mother because she didn't want to get married to Polydectes. Polydectes tricked Perseus into going on a dangeous mission so he could marry Danae.
Crossing the Threshold
Perseus makes a promise to complete the mission before finding out what the task was. When Polydectes told Perseus that he wanted Medusa's head, Perseus did not think he would survive. He said the mission was impossible because Medusa was so powerful. Perseus knew he had to complete the mission, because the promise was already made.
Test, Allies, and Enemies
Before Perseus leaves for the mission, he meets two mentors. Athena flew down and gave him her shield of brass to use as a mirror to reflect Medusa. Hermes came to guide him along the mission, and give him a sword that could never be broken, not even by Medusa's scales.
Perseus and Hermes travel to Medusa's home, where they find the gray women. Perseus steals their eye so he can find out where the nymphs of the north are. Once he finds the nymphs of the north, they give him the three magical gifts that he needed to defeat Medusa. The gifts where, winged sandals, a magic wallet, and a cap that makes him invisable.
Perseus's allies throughout the story are Athena, Hermes and the nymphs of the north. Hermes guided him for the entire journey. Athena gave him advice on how to kill Medusa. The nymphs of the north gave him the gifts to fight Medusa happily.
