<P> From the Hesperides he received a knapsack (kibisis) to safely contain Medusa's head . Zeus gave him an adamantine sword (a Harpe) and Hades' helm of darkness to hide . Hermes lent Perseus winged sandals to fly, and Athena gave him a polished shield . Perseus then proceeded to the Gorgons' cave . </P> <P> In the cave he came upon the sleeping Medusa . By viewing Medusa's reflection in his polished shield, he safely approached and cut off her head . From her neck sprang Pegasus ("he who sprang") and Chrysaor ("sword of gold"), the result of Poseidon and Medusa's meeting . The other two Gorgons pursued Perseus, but, wearing his helm of darkness, he escaped . From here he proceeded to visit Atlas, king of Mauretania, who had refused him hospitality; in revenge Perseus turned him to stone . </P> <P> On the way back to Seriphos Island, Perseus stopped in the kingdom of Aethiopia . This mythical Ethiopia was ruled by King Cepheus and Queen Cassiopeia . Cassiopeia, having boasted her daughter Andromeda equal in beauty to the Nereids, drew the vengeance of Poseidon, who sent an inundation on the land and a sea serpent, Cetus, which destroyed man and beast . The oracle of Ammon announced that no relief would be found until the king exposed his daughter Andromeda to the monster, and so she was fastened naked to a rock on the shore . Perseus slew the monster and, setting her free, claimed her in marriage . </P> <P> Perseus married Andromeda in spite of Phineus, to whom she had before been promised . At the wedding a quarrel took place between the rivals, and Phineus was turned to stone by the sight of Medusa's head that Perseus had kept . Andromeda ("queen of men") followed her husband to Tiryns in Argos, and became the ancestress of the family of the Perseidae who ruled at Tiryns through her son with Perseus, Perses . After her death she was placed by Athena among the constellations in the northern sky, near Perseus and Cassiopeia . Sophocles and Euripides (and in more modern times Pierre Corneille) made the episode of Perseus and Andromeda the subject of tragedies, and its incidents were represented in many ancient works of art . </P>
