"She is a very accomplished person, I assure you," continued Quicksilver, "and has all the arts and sciences at her fingers' ends. In short, she is so immoderately wise, that many people call her wisdom personified. But, to tell you the truth, she has hardly vivacity enough for my taste; and I think you would scarcely find her so pleasant a travelling companion as myself. She has her good points, nevertheless; and you will find the benefit of them, in your encounter with the Gorgons." By this time it had grown quite dusk. They were now come to a very wild and desert place, overgrown with shaggy bushes, and so silent and solitary that nobody seemed ever to have dwelt or journeyed there. All was waste and desolate, in the gray twilight, which grew every moment more obscure. Perseus looked about him, rather disconsolately, and asked Quicksilver whether they had a great deal farther to go. "Hist! hist!" whispered his companion. "Make no noise! This is just the time and place to meet the Three Gray Women. Be careful that they do not see you before you see them; for, though they have but a single eye among the three, it is as sharp sighted as half a dozen common eyes." "But what must I do," asked Perseus, "when we meet them?" Quicksilver explained to Perseus how the Three Gray Women managed with their one eye. They were in the habit, it seems, of changing it from one to another, as if it had been a pair of spectacles, or--which would have suited them better--a quizzing glass. When one of the three had kept the eye a certain time, she took it out of the socket and passed it to one of her sisters, whose turn it might happen to be, and who immediately clapped it into her own head, and enjoyed a peep at the visible world. Thus it will easily be understood that only one of the Three Gray Women could see, while the other two were in utter darkness; and, moreover, at the instant when the eye was passing from hand to hand, neither of the poor old ladies was able to see a wink. I have heard of a great many strange things, in my day, and have witnessed not a few; but none, it seems to me, that can compare with the oddity of these Three Gray Women, all peeping through a single eye. So thought Perseus, likewise, and was so astonished that he almost fancied his companion was joking with him, and that there were no such old women in the world. "You will soon find whether I tell the truth or no," observed Quicksilver. "Hark! hush! hist! hist! There they come, now!"
