Epic Myth
The Slaying of the Gorgon
Perseus was the son of Zeus and the mortal princess Danaë. His grandfather, King Acrisius of Argos, had been told by an oracle that his grandson would one day kill him, so he set Danaë and the infant Perseus adrift at sea in a wooden chest. They washed ashore on the island of Seriphos, where they were taken in by a fisherman. Perseus grew into a brave and noble young man.
The king of Seriphos, Polydectes, desired Danaë and wanted Perseus out of the way. He tricked the young hero into promising to bring him the head of Medusa — one of the three Gorgon sisters. Medusa was a monster so horrifying that anyone who looked directly at her face was instantly turned to stone. Her hair was a writhing mass of living snakes, and her eyes burned with a petrifying gaze. No warrior had ever faced her and survived.
The gods themselves intervened to help Perseus. Athena, who despised Medusa, gave him a polished bronze shield as bright as a mirror. Hermes gave him a pair of winged sandals for flight, the cap of Hades that granted invisibility, and a special pouch called a kibisis that could safely contain Medusa's severed head without the bearer being petrified. Armed with these divine gifts and a sickle of adamantine, Perseus set out on his quest.
Perseus flew to the edge of the world where the Gorgons dwelled. He found Medusa sleeping among her two immortal sisters. Using the mirrored surface of Athena's shield to watch Medusa's reflection — never looking at her directly — Perseus descended silently from above. With a single stroke of the adamantine sickle, he severed Medusa's head. From her neck sprang two beings: Pegasus, the winged horse, and Chrysaor, a giant wielding a golden sword — children conceived through Poseidon's earlier union with Medusa.
Perseus stuffed the still-living head into the kibisis and fled on his winged sandals as the two immortal Gorgons awoke and pursued him. Protected by the cap of invisibility, he escaped their fury and soared across the sky toward home.
On his journey home, Perseus used Medusa's head as a weapon of devastating power. When the Titan Atlas refused him hospitality, Perseus revealed the head and transformed the giant into the Atlas Mountains. When he found the princess Andromeda chained to a rock as a sacrifice to a sea monster, he slew the beast and claimed her as his bride. And when he finally returned to Seriphos, he found Polydectes threatening his mother. Perseus walked into the king's hall, drew out the Gorgon's head, and turned Polydectes and his court to stone.
The prophecy about his grandfather came true as well — at a discus-throwing contest years later, Perseus's throw was caught by a gust of wind and struck Acrisius, killing him. Thus the cycle of fate that began with an oracle's warning ended exactly as foretold, proving once again that in Greek mythology, no mortal — however heroic — can escape destiny.
