Acrisius put mother and child in a chest and cast it into the sea; it washed ashore on Seriphus, where Dictys reared the boy (Apollod. 2.4.1). Homer settles the paternity: Zeus himself names \"Danaë of the fair ankles, daughter of Acrisius, who bare Perseus, pre-eminent above all warriors\" among his loves (Il. 14.319–320).",

Guided by Hermes and Athena, Perseus took the single eye and tooth of the Phorcides to learn the way to the nymphs, who gave him winged sandals, the kibisis (a wallet) and the cap of Hades that made him unseen; Hermes gave him an adamantine sickle (Apollod. 2.4.2).",

Hesiod has the same birth: \"when Perseus cut off her head, there sprang forth great Chrysaor and the horse Pegasus\" (Theog. 280–281). Ovid's Perseus tells it himself: he saw \"her horrid face\" reflected on the shield \"upon my left\" and struck while \"even her serpent-hair was slumber-bound\" (Met. 4.706).",
