Perseus did all he could to persuade them, but they were so stubborn that he was only wasting words. Meanwhile they laid out supper, which they ate in a very strange way, each taking her turn with the one tooth which they had among them, and passing it round from one to the other, just as they did with their only eye. This made the meal rather long and slow, for they ate enormously. After supper they put the eye and the tooth into a little box while they took a nap, when Perseus, watching his opportunity, snatched up the box, put on his helmet, and cried out-- "Now tell me the way to Medusa, or else you shall never see or eat again!" The poor old Graiæ went down on their knees, and implored him to give them back their only tooth and their only eye. But he said-- "It is my turn to be stubborn. Tell me where to find Medusa, and you shall have them back; but not a minute before." "I suppose we must, then," said the eldest, with a sigh. "Well, it won't be our fault now, whatever happens. And after all, it's better that you should be turned into stone than that we should be blind and starved." "Much better," her sisters groaned. "Very well, then," said the eldest Graia, "you must go straight on, night and day, until you come into the country of King Atlas, which is called Mauritania. Near the king's palace is a garden where the trees bear golden apples, guarded by a dragon. If the dragon does not devour you, you must pass the garden gate, and go on, a long, long way, till you come to a great lake where, if you do not find the Gorgons, you will be a lucky man." Perseus gave the old women back their tooth and eye, which they received with joy, and thanking them for their information, left the hut and traveled on. After many days and nights, during which he found it hard to find food, he came into a fertile country wherein stood a stately palace, so high that it seemed to touch the clouds. Hard by was a vast garden enclosed by a high wall, and at the gate, sure enough, sat a monstrous dragon with glaring eyes. But Perseus, wearing his invisible helmet, passed by safely, because unseen. In time he came to the lake, where he took off his helmet to quench his thirst. While he was drinking, he was startled by the approach of what sounded like a mighty rush of wind, and he had but just time to put on his helmet again before he saw, reflected in the lake, the flying form of the terrible Medusa--the Gorgon whom he had vowed to slay, and who, not seeing him, sat down beside him with folded wings. Well was it for Perseus that he remembered what would happen to him if he looked at Medusa. And yet how in the world was he to fight her without looking at her? That was a puzzle indeed. Suddenly he bethought himself of Minerva's shield, which was polished like a mirror. He turned it towards Medusa, and saw, not herself indeed, but her reflection in the polished shield, which did just as well.
