In the twelfth and thirteenth centuries there arose into general notoriety in Europe, a body of "Romance," which in various forms retained its popularity till the Reformation. In it the plot, the incidents, the characters, were almost wholly those of Chivalry, that bond which united the warriors of France, Spain, and Italy, with those of pure Teutonic descent, and embraced more or less firmly all the nations of Europe, excepting only the Slavonic races, not yet risen to power, and the Celts, who had fallen from it. It is not difficult to account for this latter omission. The Celts, driven from the plains into the mountains and islands, preserved their liberty, and hated their oppressors with fierce, and not causeless, hatred. A proud and free people, isolated both in country and language, were not likely to adopt customs which implied brotherhood with their foes. Such being the case, it is remarkable that when the chief romances are examined, the name of many of the heroes and their scenes of action are found to be Celtic, and those of persons and places famous in the traditions of Wales and Brittany. Of this the romances of Ywaine and Gawaine, Sir Perceval de Galles, Eric and Enide, Mort d'Arthur, Sir Lancelot, Sir Tristan, the Graal, &c., may be cited as examples. In some cases a tendency to triads, and other matters of internal evidence, point in the same direction. That Wales possessed an ancient literature, containing various lyric compositions, and certain triads, in which are arranged historical facts or moral aphorisms, has been shown by Sharon Turner, who has established the high antiquity of many of these compositions. The Mabinogion, however, though thus early recorded in the Welsh tongue, are in their existing form by no means wholly Welsh. They are of two tolerably distinct classes. Of these, the older contains few allusions to Norman customs, manners, arts, arms, and luxuries. The other, and less ancient, are full of such allusions, and of ecclesiastical terms. Both classes, no doubt, are equally of Welsh root, but the former are not more overlaid or corrupted, than might have been expected, from the communication that so early took place between the Normans and the Welsh; whereas the latter probably migrated from Wales, and were brought back and re-translated after an absence of centuries, with a load of Norman additions. Kilhwch and Olwen, and the dream of Rhonabwy, may be cited as examples of the older and purer class; the Lady of the Fountain, Peredur, and Geraint ab Erbin, of the later, or decorated. - Lady Charlotte Guest
