King Acrisius of Argos, according to Greek mythology, was visited by the oracle at Delphi and was told that his daughter Danaë would bear a son who would eventually kill him.
To prevent this, Acrisius locked Danaë in a bronze chamber to ensure that she would never have children. However, Zeus, the king of the gods, who had taken a liking to Danae, visited her in the form of a golden shower and impregnated her.
Danaë gave birth to a son, Perseus, and Acrisius, upon learning of his grandson’s birth, cast Danaë and the infant into the sea in a wooden chest.
Miraculously, both Danae and Perseus survived and washed up on the shore of the island of Seriphos, where they were taken in by the fisherman Dictys.
Perseus grew up to become a hero, and in one of his adventures, he accidentally killed Acrisius with a stray discus throw, thus fulfilling the prophecy of the oracle at Delphi.
