Perseus was well equipped when he started out. He wore Pluto's helmet and Mercury's shoes, and travelled to the lonely cave of the Gorgon without being seen and as fast as a dart of fire sent by Jupiter. Medusa paced the halls of her cave endlessly, moaning and crying in her despair, for she was never able to escape those crawling, slimy snakes which covered her head and body. Perseus waited until she was so weary that she sank down on the stones of the cave and slept. Then, taking care not to look at her hideous face but only following her image that was reflected in his shield, Perseus cut off Medusa's head and carried it away in triumph. Then the people who travelled the sea in ships were saved from her cruelty, and her power for evil was changed in Perseus' hands to a power for good. Carrying the head of Medusa high, the hero flew in the winged shoes far and wide over land and sea until he came at last to the western limit of the earth where the sun goes down. That was the realm of Atlas, one of the giants who was rich in herds and flocks and allowed no one to share his wealth or even enter his estates. Atlas' chief pride was his orchard whose fruits were all of gold, hung on golden branches and folded from sight by golden leaves. Perseus had no ambition to take this golden harvest. "I stop in your domain only as a guest," he explained to the giant, "I am of noble birth, having sprung from the gods, and I have just accomplished the brave deed of destroying the terror Medusa wrought on the sea. I ask only rest and food of you." But Atlas could think of nothing but his greed for his gold apples. "Be gone, boaster!" he cried, "or I will crush you like a worm beneath my heel. Neither your parentage or your valor shall avail you anything." Perseus did not attempt to meet the force of the giant's greater strength, but he held up the head of the Gorgon full in his face. Then the massive bulk of Atlas was slowly but surely turned to stone. His iron muscles, his brawny limbs, his huge body and head increased in size and petrified until he towered above Perseus, a mighty mountain. His beard and hair became forests, his arm and shoulders cliffs, his head a summit, and his bones rocks. For all the rest of the centuries Atlas was to stand there holding the sky with its weight of stars on his shoulders. Perseus continued his flight and he came to the country of the Ethiopians. The sea was as ruthless here as it had been when Medusa ruled the billows in her cave on the coast of Greece. As Perseus approached the coast he saw a terrible sight.
