Perseus- Greek DemigodDemigod"Slayer of Medusa"

The Prophecy and the Bronze Chamber

The story of Perseus begins with fear of the future. His grandfather Acrisius, king of Argos, consulted the oracle at Delphi about his prospects for a male heir. The oracle's response was devastating: Acrisius would have no sons, and his daughter's son would one day kill him. Determined to escape this fate, Acrisius imprisoned his daughter Danaë in an underground chamber of bronze, to prevent any man from reaching her.

But no mortal barriers can thwart a god. Zeus, desiring Danaë, transformed himself into a shower of golden light that streamed through the opening and filled her chamber. From this divine union, she conceived Perseus. When Acrisius discovered his daughter holding an infant son, he refused to believe in divine parentage but feared to kill his own grandchild directly, lest he bring blood-guilt upon himself. Instead, he sealed mother and child in a wooden chest and cast them into the sea, leaving their fate to the waves. The lyric poet Simonides captured the pathos of this scene in a famous fragment: Danaë adrift in the pitching chest, the wind and dark water terrifying her as she clutched her sleeping infant, whispering to the child who knew nothing of the bronze bolts, the salt spray, or the purple darkness of the sea above them.

The Island of Seriphos

The chest drifted across the Aegean until it washed ashore on the island of Seriphos. There, a fisherman named Dictys found it caught in his nets and rescued the woman and child within. Dictys, a good man despite his humble station, raised Perseus as his own son, while Danaë lived under his protection.

But Dictys's brother was Polydectes, the king of Seriphos, and Polydectes was not a good man. He desired Danaë and grew increasingly aggressive in his pursuit. By the time Perseus reached manhood, he was fiercely protective of his mother and had become an obstacle to the king's designs. Polydectes devised a plan to remove him permanently.

The Impossible Quest

Polydectes announced he would marry Hippodamia, princess of another land, and demanded wedding gifts from all his subjects. Perseus, poor but proud, boasted that he would bring anything the king required, even the head of Medusa, the mortal Gorgon whose gaze turned all who beheld her to stone. Polydectes immediately accepted this rash promise, knowing the quest would certainly kill the young man.

Medusa was one of three Gorgon sisters who dwelt at the edge of the world, beyond the stream of Ocean. Two of the sisters, Stheno and Euryale, were immortal; only Medusa could be killed. All three had serpents for hair and claws of bronze, and a gaze that turned the living to stone. No hero had ever faced them and survived.

Divine Aid

Perseus did not journey alone. The gods favored Zeus's son. Athena appeared to him. In Ovid's telling, she hated Medusa because Poseidon had ravished the girl in Athena's own temple, and Athena cursed her for it. The goddess gave Perseus her polished bronze shield, advising him to use its mirrored surface to view Medusa indirectly and avoid her petrifying gaze.

Hermes, the messenger god, also aided him, providing an adamantine harpe, a curved sword capable of cutting through anything and the only weapon that could sever a Gorgon's neck. But the gods did not reveal Medusa's location directly. First, Perseus had to visit the Graeae, the Grey Sisters, three ancient women who had been old since birth and who shared between them a single eye and a single tooth. Perseus found them by the shore of the great Ocean and seized the eye as it passed between them. Blind and helpless, the Graeae directed him to the Hyperborean nymphs who held the remaining equipment he needed. From these nymphs Perseus received winged sandals that granted the power of flight, the cap of Hades that rendered its wearer invisible, and a kibisis, a magical pouch that could safely contain Medusa's severed head, whose power remained lethal even after death.

The Slaying of Medusa

Perseus flew on winged sandals to the land beyond Ocean, to the place where the Gorgons slept among stone figures. Each had once been a living man who looked the wrong way. He found the three monsters lying together, serpent-hair coiled, bronze claws clutching the ground even in sleep.

Wearing the cap of invisibility, Perseus descended. He held up Athena's shield, watching the reflection of the sleeping Gorgons rather than looking directly at them. He identified Medusa, the mortal sister, and with a single stroke of the harpe severed her head.

From Medusa's neck, as the blood spurted forth, two beings emerged: Pegasus, the winged horse, and Chrysaor, a giant wielding a golden sword. These were the children of Poseidon, conceived when the sea god ravished Medusa, imprisoned within their mother until this violent birth. Perseus had no time to wonder at them. Stheno and Euryale awoke, screaming with grief and rage, but they could not see the invisible hero. He placed Medusa's head in the kibisis and fled on winged sandals, faster than even immortal Gorgons could follow.

The Rescue of Andromeda

Flying home over the coast of Ethiopia, Perseus saw a sight that stopped him mid-flight: a beautiful woman chained to a rock by the sea, waves crashing around her, a monstrous shape rising from the depths. This was Andromeda, daughter of King Cepheus and Queen Cassiopeia. Her mother had boasted that Andromeda was more beautiful than the Nereids, the sea nymphs, and the offended nymphs had complained to Poseidon. The sea god sent a flood and a monster to devastate the kingdom; the oracle revealed that only Andromeda's sacrifice could appease divine anger.

Perseus descended and made a bargain with the desperate king: he would kill the monster in exchange for Andromeda's hand in marriage. The beast rose from the water, trailing scales and foam. Perseus drew the Gorgon's head from the kibisis and turned the creature to stone.

Andromeda was freed, but her rescue was not without complication. She had been promised to her uncle Phineus, who arrived at the wedding feast with armed men to claim his bride. Perseus, outnumbered, resorted again to Medusa's head. He warned his friends to look away, then unveiled the Gorgon's face. Phineus and his soldiers became a gallery of stone statues, frozen in attitudes of attack, their weapons raised forever.

The Fulfillment of Prophecy

Perseus returned to Seriphos to find his mother Danaë sheltering in a temple, having fled there to escape Polydectes's increasingly violent pursuit. Perseus went to the king's hall, where Polydectes sat feasting with his men. When the king mocked him, asking where his wedding gift was, Perseus reached into the kibisis and brought forth Medusa's head. Polydectes and all his court became stone.

Perseus made the good fisherman Dictys king of Seriphos and returned the divine equipment to Hermes and the shield to Athena, who set Medusa's head upon her aegis. He sailed with his mother and Andromeda to Argos, to be reconciled with his grandfather Acrisius.

But Acrisius had not forgotten the prophecy. When he learned Perseus was coming, he fled north to Larissa. By chance or fate, Perseus followed, competing in funeral games held there. In the discus throw, a gust of wind carried his throw astray. The discus struck a spectator in the head and killed him. The spectator was Acrisius, and the prophecy was fulfilled despite every precaution.

Mycenae and the Stars

Ashamed to rule Argos after killing its king, even by accident, Perseus exchanged kingdoms with his cousin Megapenthes, taking Tiryns instead. He founded the great citadel of Mycenae nearby. Pausanias records two origins for the name: the mykes, or cap, of Perseus's scabbard that fell at the site, and a mushroom growing there beside a spring. The Cyclopes built its walls from stones so vast no team of mules could shift them. His great-grandson was Heracles.

Even the Persians claimed him. Herodotus reports that when Xerxes sent ambassadors to Argos before his invasion, they cited Perseus's son Perses as the ancestor of the Persian people, and the Argives, swayed by this claimed kinship, stayed neutral while the rest of Greece fought for its survival.

Perseus was placed among the stars near Andromeda, Cassiopeia, and Cepheus: the whole cast of the rescue, fixed overhead. The variable star Algol, which ancient astronomers observed to brighten and dim in a regular cycle, marked the Gorgon's severed head in the hero's outstretched hand.
