QUOTE:
When Perseus grew up, Polydectes gave him a series of challenging tasks to complete. Armed with a sword made by the god Hermes, winged sandals, and a shiny bronze shield given to him by the goddess Athena, Perseus slew the dreaded monster Medusa. This hideous creature had writhing snakes for hair, elephant-like tusks for teeth, and blood-red eyes. Whoever looked at her was instantly turned to stone.
