Now this young man was no other than the wild man whom Guerrino had set free from the prison of King Filippomaria his father. This youth, after wandering through various countries and strange lands, met one day by chance a very lovely and benignant fairy, who was at that time suffering from a certain distemper. She, when she looked upon him and saw how misshapen and hideous he was, laughed so violently at the sight of his ugliness that she caused to burst an imposthume which had formed in the vicinity of her heart—an ailment which might well have caused her death by suffocation. And at that very moment she was delivered from all pain and trouble of this infirmity, as if she had never been afflicted therewith in the past, and restored to health. Wherefore the good fairy, in recompense for so great a favour done to her, said to him, not wishing to appear ungrateful to him: ‘O thou creature, who art now so deformed and filthy, since thou hast been the means of restoring to me my health which I so greatly desired, go thy ways, and be thou changed from what thou art into the fairest, the wisest, and the most graceful youth that may anywhere be found. And, besides this, I make you the sharer with me of all the power and authority conferred upon me by nature, whereby you will be able to do and to undo whatsoever you will according to your desire.’ And having presented to him a noble horse endowed with magic powers, she gave him leave to go whithersoever he would. Thus as Guerrino journeyed along with the young man, knowing nothing as to who he might be, but well known of him the while, they came at last to a mighty and strong city called Irlanda, over which at that time ruled King Zifroi. This King Zifroi was the father of two daughters, graceful to look upon, of modest manners, and in beauty surpassing Venus herself, one of them named Potentiana and the other Eleuteria. They were held so dear by the king their father that he could see by no other eyes than theirs. As soon as Guerrino entered the city of Irlanda with the unknown youth and with his train of servants, he hired a lodging of a certain householder who was the wittiest fellow in the whole of Irlanda, and who treated his guests with cheer of the best. And on the day following, the unknown youth made believe that he must needs depart and travel into another country, and went to take leave of Guerrino, thanking him in hearty wise for the boon of his company and good usage, but Guerrino, who had conceived the strongest love and friendship for him, would on no account let him go, and showed him such strong evidence of his good feeling that in the end the young man agreed to tarry with him.
