It is, however, very disagreeable to have to speak disrespectfully of a writer so agreeable in himself and so really important in our story as Chrestien. His own gifts and performances are, as it seems to me, clear enough. He took from this or that source--his selection of the _Erec_ and _Percivale_ matters, if not also that of _Yvain_, suggests others besides the, by that time as I think, concentrated Arthurian story--and from the Arthuriad itself the substance of the _Chevalier a la Charette_. He varied and dressed them up with pleasant etceteras, and in especial, sometimes, though not always, embroidered the already introduced love-motive with courtly fantasies and with a great deal of detail. I should not be at all disposed to object if somebody says that he, before any one else, set the type of the regular verse _Roman d'aventures_. It seems likely, again, from the pieces referred to above, that he may have had originals more definitely connected with Celtic sources, if not actually Celtic themselves, than those which have given us the mighty architectonic of the "Vulgate" _Arthur_. In his own way and place he is a great and an attractive figure--not least in the history of the novel. But I can see nothing in him that makes me think him likely, and much that makes me think him utterly unlikely, to be the author of what I conceive to be the greatest, the most epoch-making, and almost the originating conception of the novel-romance itself. Who it was that did conceive this great thing I do not positively know. All external evidence points to Walter Map; no internal evidence, that I have seen, seems to me really to point away from him. But if any one likes let us leave him a mere Eidolon, an earlier "Great Unknown." Our business is, once more, with what he, whoever he was, did. [Sidenote: The constitution of the Arthuriad.]
