Perseus goes to the 3 grey sisters after getting advice from Hermes. He eventually gets out where the nymphs are and goes to them next.
After talking and dealing with the nymphs he gets them to tell him where Medusa is then he goes to her.
Perseus went and got the head of Medusa using a shield that the nymphs gave him. When he got her head he ran.
On his way back Perseus danced with the nymphs then went on his way. Before he got home he came across a girl that was being sacrificed as a punishment because of something that her mother had done. The sea serpent was about to kill the girl when Perseus killed that serpent and as a present he was to marry the girl.
When Perseus arrived home he saw that king polydectus was to marry his mother. Perseus then turned everyone to stone with Medusa’s head except his mother.
Dane told Perseus that her dad king Acrisius was in the room and he had killed him just like the prophecy said would happen. Then after he throws Medusa’s head in the ocean it sank to the bottom.
