Powel, Prince of Dyfed. OWEL, 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 pre- pared 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.” “J 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.
