One day, Danaë will have a son that will kill you.
A fisherman lucky rescued them from the chest and they lived with him for many years.
The King of Argos had a daughter named Danaë. He was told by a god named Delphi that he would never have a son, but Danaë's son would kill him.
Years later, the king of the island fell in love with Danaë. Since Perseus did not have a wedding present, he said he would get Medusa's head.
The king locked away Danaë in a bronze house, where she couldn't be reached. He thought he was safe from death. But, Zeus appeared in the house through gold rain, and she would carry his son, Perseus.
In alarm, the king put the mother and son in a chest and threw it into the sea. He hoped this would avoid his death if Perseus wasn't near him.
All was well until the king of the island fell in love with Danaë. The king wanted to marry her, but did not want Perseus. Since Perseus was without a wedding gift, he declared he would get Medusa's head and bring it back, a seemingly impossible task.
Perseus was given many tools to help him complete the task. Hermes gave him a sword and the directions to the Gray Women, who gave him directions to the Nymphs of the North. Athena gave him a shield to protect him from Medusa. When he reached the country of Hyperboreans, they gave him winged sandals so he could fly, a magic wallet that expanded to fit whatever was put in it, and lastly a cap that made whoever wore it invisible.
An invisible cap!
When he arrived, all three Gorgons were asleep. Perseus put his invisible cap on and used his shield to see their reflection. Using his shield, he killed Medusa and put it in his expandable wallet. When he returned, he rescued a woman and later married her. He also turned the king of the island and his guests to stone.
