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 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.
