He impersonated him before going to his chamber and had sex with his wife, Danae. Later, the real Acrisius arrived and realized what happened, but Zeus turned into an eagle and flew to Olympus. After Danae gave birth to a son, an enraged Acrisius decided to execute both of them out of revenge against Zeus. He locked them in a coffin and brought them on the edge of the sea where he declared that he cursed Zeus, but a lighting struck him and severely deformed his body.
