The Nymphs next produced a pair of shoes , or slippers , or sandals , with a nice little pair of wings at the heel of each . `` Put them on , Perseus , '' said Quicksilver . `` You will find yourself as light-heeled as you can desire , for the remainder of our journey . '' So Perseus proceeded to put one of the slippers on , while he laid the other on the ground by his side . Unexpectedly , however , this other slipper spread its wings , fluttered up off the ground , and would probably have flown away , if Quicksilver had not made a leap , and luckily caught it in the air . `` Be more careful , '' said he , as he gave it back to Perseus . `` It would frighten the birds , up aloft , if they should see a flying slipper amongst them . '' When Perseus had got on both of these wonderful slippers , he was altogether too buoyant to tread on earth . Making a step or two , lo and behold ! upward he popt into the air , high above the heads of Quicksilver and the Nymphs , and found it very difficult to clamber down again . Winged slippers , and all such high-flying contrivances , are seldom quite easy to manage , until one grows a little accustomed to them . Quicksilver laughed at his companion 's involuntary activity , and told him that he must not be in so desperate a hurry , but must wait for the invisible helmet . The good-natured Nymphs had the helmet , with its dark tuft of waving plumes , all in readiness to put upon his head . And now there happened about as wonderful an incident as anything that I have yet told you . The instant before the helmet was put on , there stood Perseus , a beautiful young man , with golden ringlets and rosy cheeks , the crooked sword by his side , and the brightly polished shield upon his arm , -- a figure that seemed all made up of courage , sprightliness , and glorious light . But when the helmet had descended over his white brow , there was no longer any Perseus to be seen ! Nothing but empty air ! Even the helmet , that covered him with its invisibility , had vanished ! `` Where are you , Perseus ? '' asked Quicksilver .
`` Why , here , XXXXX be sure ! ''
