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 -- 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 .

But , XXXXX the middle of the third sister 's forehead , there was a very large , bright , and piercing eye , which sparkled like a great diamond in a ring ; and so penetrating did it seem to be , that Perseus could not help thinking it must possess the gift of seeing in the darkest midnight just as perfectly as at noonday .
