So married they were, and Jack turned out a real good husband. And the squire and his lady were never tired of praising their son-in-law, "Jack the Cunning Thief." Powel, Prince of Dyfed. [Illustration: P] Powel, Prince of Dyfed, was lord of the seven Cantrevs of Dyfed; and once upon a time Powel was at Narberth, his chief palace, where a feast had been prepared for him, and with him was a great host of men. And after the first meal, Powel arose to walk, and he went to the top of a mound that was above the palace, and was called Gorseth Arberth. "Lord," said one of the court, "it is peculiar to the mound that whosoever sits upon it cannot go thence without either receiving wounds or blows, or else seeing a wonder." "I fear not to receive wounds and blows in the midst of such a host as this; but as to the wonder, gladly would I see it. I will go, therefore, and sit upon the mound." And upon the mound he sat. And while he sat there, they saw a lady, on a pure white horse of large size, with a garment of shining gold around her, coming along the highway that led from the mound; and the horse seemed to move at a slow and even pace, and to be coming up towards the mound. "My men," said Powel, "is there any among you who knows yonder lady?" "There is not, lord," said they. "Go one of you and meet her, that we may know who she is." And one of them arose; and as he came upon the road to meet her she passed by, and he followed as fast as he could, being on foot; and the greater was his speed, the farther was she from him. And when he saw that it profited him nothing to follow her, he returned to Powel, and said unto him, "Lord, it is idle for any one in the world to follow her on foot." "Verily," said Powel, "go unto the palace, and take the fleetest horse that thou seest, and go after her." And he took a horse and went forward. And he came to an open level plain, and put spurs to his horse; and the more he urged his horse, the farther was she from him. Yet she held the same pace as at first. And his horse began to fail; and when his horse's feet failed him, he returned to the place where Powel was. "Lord," said he, "it will avail nothing for any one to follow yonder lady. I know of no horse in these realms swifter than this, and it availed me not to pursue her."
