Geoffrey may or may not have intended his astonishing story to be seriously accepted, but in fact it was received with almost universal credence. For centuries it was incorporated in outline or in excerpts into almost all the sober chronicles, and what is of much more importance for literature, it was taken up and rehandled in various fashions by very numerous romancers. About twenty years after Geoffrey wrote, the French poet Wace, an English subject, paraphrased his entire 'History' in vivid, fluent, and diffuse verse. Wace imparts to the whole, in a thorough-going way, the manners of chivalry, and adds, among other things, a mention of the Round Table, which Geoffrey, somewhat chary of the supernatural, had chosen to omit, though it was one of the early elements of the Welsh tradition. Other poets followed, chief among them the delightful Chrêtien of Troyes, all writing mostly of the exploits of single knights at Arthur's court, which they made over, probably, from scattering tales of Welsh and Breton mythology. To declare that most romantic heroes had been knights of Arthur's circle now became almost a matter of course. Prose romances also appeared, vast formless compilations, which gathered up into themselves story after story, according to the fancy of each successive editor. Greatest of the additions to the substance of the cycle was the story of the Holy Grail, originally an altogether independent legend. Important changes necessarily developed. Arthur himself, in many of the romances, was degraded from his position of the bravest knight to be the inactive figurehead of a brilliant court; and the only really historical element in the story, his struggle against the Saxons, was thrust far into the background, while all the emphasis was laid on the romantic achievements of the single knights.
