The Four Branches of the Mabinogi

Pwyll Prince of Dyved was lord of the seven Cantrevs of Dyved; and once upon a time he was at Narberth his chief palace, and he was minded to go and hunt, and the part of his dominions in which it pleased him to hunt was Glyn Cuch. So he set forth from Narberth that night, and went as far as Llwyn Diarwyd. And that night he tarried there, and early on the morrow he rose and came to Glyn Cuch, when he let loose the dogs in the wood, and sounded the horn, and began the chase. And as he followed the dogs, he lost his companions; and whilst he listened to the hounds, he heard the cry of other hounds, a cry different from his own, and coming in the opposite direction.

And he beheld a glade in the wood forming a level plain, and as his dogs came to the edge of the glade, he saw a stag before the other dogs. And lo, as it reached the middle of the glade, the dogs that followed the stag overtook it and brought it down. Then looked he at the colour of the dogs, staying not to look at the stag, and of all the hounds that he had seen in the world, he had never seen any that were like unto these. For their hair was of a brilliant shining white, and their ears were red; and as the whiteness of their bodies shone, so did the redness of their ears glisten. And he came towards the dogs, and drove away those that had brought down the stag, and set his own dogs upon it.
