When Acrisius learnt of Danae having a baby boy, he locked her in a wooden chest with her newborn son Perseus, and threw them to sea. Under Zeus' watchful eye, the chest arrived safely on the shores of Seriphos, where the chest was drawn and opened by a fisherman, Diktys. The fisherman kindly sheltered mother and son, who took care of them well along with his wife. Perseus grew strong and handsome, learning how to use the sword and ride the horse.
