Galahad version of the Quest, substituted for the "childhood" opening of this hypothetical source the one now found in his version, and the Gonemans episode went with the remainder of that part of the story. When the hero comes to the Grail Castle, the author is puzzled; his hero knows beforehand what he has to do, sets out with the distinct purpose of doing it, and yet remains silent. To account for this silence the author uses the motive belonging to a discarded episode, but applies the words to his hermit, forgetting that he had put no such words into his mouth, and that, attributed to him, the injunction to keep silence became simply meaningless. Is the model treated in this way by the Didot-Perceval Chrestien's poem? Hardly, for this reason. After the Good Friday incident occurs the remarkable passage, quoted (supra, p. 31), as to the silence of the trouvères respecting it. Chrestien gives the incident in full, and the author of the Perceval could have had no reason for his stricture, or could not have ventured it had he been using Chrestien's work. Two hypotheses then remain; the unknown source may have been a version akin to that used by Chrestien and Gautier, or it may have been a summary abridgment of the Conte du Graal, in which, inter alia, the Good Friday incident was left out. In either case the presence of the passage in the Perceval is equally hard of explanation; but the first hypothesis is favoured by the primitive character of the incident of the Ford Perillous, and several other features which will be touched upon in their place. The Didot-Perceval would thus be an attempt to provide an ending for Borron's poem by adapting to its central donnée a version of the Perceval sage akin to that which forms the groundwork of the Conte du Graal, its author being largely influenced by the Galahad form of the Quest as found in the Queste. If this view be correct, the testimony of Perceval (wherever not influenced by Borron's poem or the Queste) is of value in determining the original form of the story, the more so from the author's evident want of skill in piecing together his materials. It will, therefore, be used in the following section, which deals with the relationship of the Conte du Graal and the Mabinogi of Peredur ab Evrawc.
