Then she told the travelers to be of brave heart and of valiant hope, because there lay before them an ordeal demanding all their prowess, and after that the prospect of a great reward. "Now," she said, "that you have learned to love me, and to desire to have your dwelling here with me, you must go forth to prove your knighthood. I am not inaccessible, but no man must think to win me for his lady unless he first justify his fealty by noble service. The world to which you now go is a world of mirage and of phantasms, which appear real only to those who have never reached and seen this realm of mine on the heavenward side of the sun. You will have to pass through ways beset by monstrous spectres, over wastes where rage ferocious hydras, chimeras, and strange dragons breathing flame. You must journey past beautiful shadowy islets of the summer sea, in whose fertile bays the cunning sirens sing; you must brave the mountain robber, the goblins of the wilderness, and the ogre whose joy is to devour living men. But fear nothing, for all these are but phantoms; nor do you need any sword or spear to slay them, but only a loyal mind and an unswerving purpose. Let not your vision be deceived, nor your heart beguiled; return to me unscathed through all these many snares, and doubt not the worth and greatness of the guerdon I shall give. Nor think you go unaided. With each of you I send a guide and monitor; heed well his voice and follow where he leads." II.
