These apparently casual records of Arthurian marvels are noteworthy, not only as indicating an early association of Arthurian traditions with the topography of Wales, but also as affording a connecting link between the earliest Latin documents in which Arthur’s name is found and one of the very oldest of the Welsh Arthurian tales. In the Welsh romance, or rather fairy-tale, of _Kulhwch and Olwen_,--the primitive literary form of which probably dates from the tenth century,[30]--the hunting of the _Twrch Trwyth_, or the Boar Trwyth (the _porcus Troit_ of Nennius), forms one of the capital features. Now, in that hunt, as described in _Kulhwch and Olwen_, Arthur’s dog Cabal, or Cavall,--which is the Welsh form of the name,--takes part; he is led to the chase by Arthur’s faithful henchman, Bedwyr, or Bedivere.[31] Nor was it in bringing to bay “the boar Troit” alone that Cavall took part. He was conspicuous in the capture and the slaughter of another monster, who is called an Arch- or Head-Boar, bearing the fearsome name of “Yskithyrwyn Benbaedd.” “And Arthur,” we read,[32] “went himself to the chase, leading his own dog Cavall. And Kaw, of North Britain, mounted Arthur’s mare Llamrei, and was first in the attack. Then Kaw, of North Britain, wielded a mighty axe, and absolutely daring he came valiantly up to the boar, and clave his head in twain. And Kaw took away the tusk. Now the boar was not slain by the dogs that Yspaddaden had mentioned, but by Cavall, Arthur’s own dog.”[33] The battle of Mount Badon, as we have seen, is recorded in the _Annales Cambriæ_, contained in a MS of the tenth century. Still more interesting is another record in that document under the year 537. In that year, we read, was fought “the battle of Camlan, in which Arthur and Medraut fell.” Although we hear nothing of Medraut’s treachery, or of his being Arthur’s nephew, here, so far as we know, is the first recorded allusion to what subsequently became one of the prime tragic features in Arthurian story. Medrod, or Modred, is the villain of the romances, and Camlan is that “dim, weird battle of the west,” where Arthur fought the “traitor of his house,” and “Striking the last stroke with Excalibur Slew him, and all but slain himself, he fell.”[34]
