As Perseus drew near, unseen by them, because of his magic helmet, the sisters were passing their one eye from hand to hand, so that at that moment all three were blind.
Perseus saw his chance, and stretching out his hand seized the eye. They, each thinking the other had it, began to quarrel. But Perseus cried, 'I hold the eye in my hand. Tell me where I may find Medusa and you shall have it back.'
The sisters were startled by a voice when they had neither seen nor heard any one approach; they were more startled by what the voice said.
Very unwilling were they to tell their secret, yet what could they do if the stranger refused to give back their one eye? Already he was growing impatient, and threatening to throw it into the sea. So lest he should really fling it away they were forced to tell him where he would find the Gorgon. Then Perseus, placing the eye in one of the eager, out-stretched hands, sped swiftly on his journey.
As he reached the land of which the Grææ had told him, he heard the restless beating of the Gorgon's wings, and he knew that his quest was well-nigh over.
Onward still he flew, and then raising his burnished shield he looked into it, and lo! he saw the images of the Gorgons. They lay, all three, fast asleep on the shore.
Unsheathing his sword, Perseus held it high, and then, keeping his gaze fixed upon the shield, he flew down and swiftly cut off Medusa's head and thrust it into a magic bag which he carried slung over his shoulder.
Now as Perseus seized the terrible head, the serpents coiled around the Gorgon's brow roused themselves, and began to hiss so fiercely that the two sisters awoke and knew that evil had befallen Medusa.
They could not see Perseus, for he wore his magic helmet, but they heard him, and in an instant they were following fast, eager to avenge the death of their sister.
For a moment the brave heart of the hero failed.
