Danae was the princess of Argos, in Peloponessos. She was a daughter of King Akrisios. When her father learns of a prophecy that he was to be killed by a son of his daughter, he locked her away, but Zeus, disguised as a golden shower, impregnated her. She had a son named Perseus. After hearing of this, the king locked them in a chest and cast them out at sea. Perseus did eventually fulfill the prophecy.
