Now, of Chrêtien's source he only tells us that Count Philip of Flanders gave him the book in which he found this story of Perceval and the Grail, but of the author of the book he says no word. Of Kiot's source, Wolfram tells us that the story of the origin of the Grail was found in a MS. at Toledo, written in Arabic by a heathen astronomer, Flegetanis; and it also appears, from a passage in Book VIII. p. 238, that the story of Parzival was contained in the same MS. That Kiot then sought through the chronicles of various countries for some confirmation of the tale, and finally found the record of the Grail kings in the chronicles of Anjou. Of the sources thus variously given, the book possessed by Count Philip of Flanders, the Arabic MS. of Flegetanis, the Chronicles of Anjou, and Kiot's poem founded upon these two last, the Chronicles of Anjou alone remain to us; do they throw any light on the question or not? It has long been asserted that they do _not_, and it is true that they contain no record of the Grail kings, nor, though King Arthur is mentioned, and treated as an historical personage, do we find any mention of Mazadan, Gamuret, Herzeleide, and Parzival under the same names; but it also seems equally clear that the writer of the _Parzival_ knew the Chronicles of Anjou, and in the case of each of the characters mentioned above it is not difficult to trace a distinct correspondence between what is recorded in the _Parzival_ and real personages and events of Angevin history. (A reference to Appendix A, vol. i., 'on the Angevin allusions' will show how close in some cases this parallel is.) Now we find that the greater number of these allusions are contained in the earlier part of the poem, Books I., II., and III., some of the most striking, _e.g._ the account of the origin of the Angevin House; the parallel between Gamuret and Fulk V.; and the introduction of Herzeleide, being in the two first books; _i.e._ that part of the poem peculiar to Wolfram's version is also the part of the poem richest in indications of a knowledge of Angevin history.
