Snatching the eye, Perseus compelled the Grææ, as the price of its restoration, to tell him how he might obtain the helmet of Hades that renders its wearer invisible, and the winged shoes and pouch that were necessary. With this outfit, to which Minerva added her shield and Mercury his knife, Perseus sped to the hall of the Gorgons. In silence sat two of the sisters,-- But a third woman paced about the hall, And ever turned her head from wall to wall And moaned aloud, and shrieked in her despair; Because the golden tresses of her hair Were moved by writhing snakes from side to side, That in their writhing oftentimes would glide On to her breast, or shuddering shoulders white; Or, falling down, the hideous things would light Upon her feet, and crawling thence would twine Their slimy folds about her ankles fine.[206] [Illustration: FIG. 119. PERSEUS From the sculpture by Cellini] This was Medusa. Her, while she was praying the gods to end her misery, or, as some say, while she was sleeping, Perseus approached, and, guided by her image reflected in the bright shield which he bore, cut off her head, and so ended her miserable existence. Thus are described the horror and the grace of her features in death: It lieth, gazing on the midnight sky, Upon the cloudy mountain peak supine; Below, far lands are seen tremblingly; Its horror and its beauty are divine. Upon its lips and eyelids seems to lie Loveliness like a shadow, from which shine, Fiery and lurid, struggling underneath, The agonies of anguish and of death. Yet it is less the horror than the grace Which turns the gazer's spirit into stone; Whereon the lineaments of that dead face Are graven, till the characters be grown Into itself, and thought no more can trace; 'Tis the melodious hue of beauty thrown Athwart the darkness and the glare of pain, Which humanize and harmonize the strain.[207]... =153. Perseus and Atlas.= From the body of Medusa sprang the winged horse Pegasus, of whose rider, Bellerophon, we shall presently be informed. [Illustration: FIG. 120. PERSEUS WITH HEAD OF MEDUSA]
