When Acrisius inquired of the oracle how he should get male children, the god said that his daughter would give birth to a son who would kill him. Fearing that, Acrisius built a brazen chamber under ground and there guarded Danae. However, she was seduced, as some say, by Proetus, whence arose the quarrel between them; but some say that Zeus had intercourse with her in the shape of a stream of gold which poured through the roof into Danae’s lap. When Acrisius afterwards learned that she had got a child Perseus, he would not believe that she had been seduced by Zeus, and putting his daughter with the child in a chest, he cast it into the sea. The chest was washed ashore on Seriphus, and Dictys took up the boy and reared him. Polydectes, brother of Dictys, was then king of Seriphus and fell in love with Danae, but could not get access to her, because Perseus was grown to man’s estate. So he called together his friends, including Perseus, under the pretext of collecting contributions towards a wedding-gift for Hippodamia, daughter of Oenomaus. Now Perseus having declared that he would not stick even at the Gorgon’s head, Polydectes required the others to furnish horses, and not getting horses from Perseus ordered him to bring the Gorgon’s head. So under the guidance of Hermes and Athena he made his way to the daughters of Phorcus, to wit, Enyo, Pephredo, and Dino; for Phorcus had them by Ceto, and they were sisters of the Gorgons, and old women from their birth. The three had but one eye and one tooth, and these they passed to each other in turn. Perseus got possession of the eye and the tooth, and when they asked them back, he said he would give them up if they would show him the way to the nymphs. Now these nymphs had winged sandals and the kibisis, which they say was a wallet. But Pindar and Hesiod in The Shield say of Perseus:—

“But all his back had on the head of a dread monster, The Gorgon, and round him ran the kibisis.”
