It may seem difficult to account for this. Although the ancient dominion of the Celts over Europe is not without enduring evidence in the names of the mountains and streams, the great features of a country, yet the loss of their prior language by the great mass of the Celtic nations in Southern Europe (if indeed their successors in territory be at all of their blood), prevents us from clearly seeing, and makes us wonder, how stories, originally embodied in the Celtic dialects of Great Britain and France, could so influence the literature of nations to whom the Celtic languages were utterly unknown. Whence then came these internal marks, and these proper names of persons and places, the features of a story usually of earliest date and least likely to change? These romances were found in England, France, Germany, Norway, Sweden, and even Iceland, as early as the beginning of the thirteenth and end of the twelfth century. The Germans, who propagated them through the nations of the North, derived them certainly from France. Robert Wace published his Anglo-Norman Romance of the Brut d’Angleterre about 1155. Sir Tristan was written in French prose in 1170; and The Chevalier au Lion, Chevalier de l’Epée, and Sir Lancelot du Lac, in metrical French, by Chrestien de Troyes, before 1200. From these facts it is to be argued that the further back these romances are traced, the more clearly does it appear that they spread over the Continent from the North-west of France. The older versions, it may be remarked, are far more simple than the later corruptions. In them there is less allusion to the habits and usages of Chivalry, and the Welsh names and elements stand out in stronger relief. It is a great step to be able to trace the stocks of these romances back to Wace, or to his country and age. For Wace’s work was not original. He himself, a native of Jersey, appears to have derived much of it from the “Historia Britonum” of Gruffydd ab Arthur, commonly known as “Geoffrey of Monmouth,” born 1128, who himself professes to have translated from a British original. It is, however, very possible that Wace may have had access, like Geoffrey, to independent sources of information.
