I. Son of Jupiter and Danăē, abandoned by his grandfather Acrisius, but rescued and brought up by Polydectes, king of Seriphus. When grown up, he undertook, at the instigation of Polydectes, an expedition against the islands of the Gorgons, and received from Vulcan a sickle-shaped sword, from Mercury winged shoes, and from Minerva a shield and the flying horse Pegasus. Thus armed, he killed and cut off the head of Medusa, whose look turned every thing into stone. On his way back, he, by means of it, turned into stone a sea-monster to which Andromeda, the daughter of Cepheus, was exposed, and married her. Their son Perses became the progenitor of the Persians. After his death, Perseus was placed among the constellations, Ov. M. 4, 609 sq.; Hyg. Fab. 64; 244; id. Astron. 12; Cic. N. D. 2, 44, 112; Prop. 2, 30 (3, 28), 4; 2, 28 (3, 24), 22; Serv. Verg.
