Explore the tale of young hero, Perseus, who sets out to defeat the terrifying Medusa, who could turn any man into stone. Learn about the birth and adventures of this famous hero and the lessons learned from the stories that surround him.

The Birth of Perseus

In order to fully understand the tale of Perseus and Medusa, it is first necessary to tell the story of Perseus' birth. Acrisius, the king of the Argos, had only one daughter, a beautiful girl named Danae. As Acrisius grew older he became worried because he had no sons, and he consulted the oracle at Delphi to ask if his children would inherit his kingdom. The oracle revealed that Acrisius would have no sons; however, his kingdom would pass to his grandson, the child of his daughter, Danae. She also revealed a dark and deadly secret: Acrisius was fated to die at the hand of his grandson.

Acrisius became fearful of this future event and so he locked the lovely Danae in a tower and refused to allow any men to see her. He hoped that by denying his daughter a husband, Acrisius could avoid the dark fate the oracle had promised. However, despite the precautions Acrisius took, he could not hide his daughter's loveliness from the Greek god Zeus. Zeus spotted Danae from the clouds and he appeared to her in a shower of gold.

When Acrisius realized that his daughter was pregnant as a result of the god's visits, he sealed Danae and her baby, Perseus, into a wooden chest and set it out to sea. Acrisius believed that both the mother and the infant would be drowned in the water or crushed against the rocky sea shore. But Danae and Perseus did not perish in the cold sea water; instead, their wooden chest washed up in the kingdom of King Polydectes. A fisherman discovered the pair and brought them to the king who was immediately entranced by the lovely young mother.

Danae and Perseus lived happily in the court of King Polydectes for many years and Perseus grew into a young man. When Perseus reached adulthood, the king, who had long loved his mother, proposed that he marry Danae and make her his queen. Perseus did not like this idea and refused to consent to his mother's marriage.

Perseus and Medusa

The cunning king hatched a plan to rid his kingdom of the troublesome young man so he might marry the beautiful Danae. One day, he suggested that Perseus set out on a grand adventure to defeat one of the fearsome Gorgon sisters, terrible monsters who terrorized the Greeks and defeated many would-be heroes. Eager for adventure, Perseus agreed to seek and defeat one of the Gorgon sisters, Medusa, a horrible monster who had the power of turning anyone who saw her into stone. Polydectes rejoiced that the youth would probably never return from his travels and concluded that he could marry Danae without difficulty.

Fortunately, Perseus was beloved of the gods. Athena, the Greek goddess of wisdom, and Hermes, the Greek god of mischief, appeared to the young man early in his travels. Athena provided the hero with valuable wisdom and advised him to seek out the Graeae, three old women who guarded valuable treasures that would help Perseus to defeat Medusa. Hermes gave the young hero a magic looking glass, which would allow him to see the monster without looking into her eyes.

Perseus found the three old women; however, they would not give up the treasures. Perseus noticed that the three sisters all shared one eye, passing it between them. The nimble young man snatched up the eye and demanded that the sisters give him three things: a magic helmet that would make him invisible, a pair of winged sandals that would allow him to fly, and a magic bag that would safely contain Medusa's head. In addition, Perseus forced the Graeae to tell him where the Gorgon sisters lived.
