Danae

Danae, daughter of Acrisius, king of Argos, grandson of Danaus, was imprisoned by her father owing to an oracular response that she would be the mother of a child, the slayer of his grandfather. Visited by Zeus in prison amid a shower of gold, she eventually gave birth to a son, Perseus. Mother and son were thrown into the sea in a chest by Acrisius, and drifted to the island of Seriphos. Arrived at manhood, Perseus accompanied his mother to Argos, and subsequently, as foretold, Acrisius, through an accident, met with his death at the hands of his grandson at Larissa.
