But certain links were missing in the chain of evidence, and the work was not complete. No inconsiderable part of the information at my disposal depended upon personal testimony, the testimony of those who knew of the continued existence of such a ritual, and had actually been initiated into its mysteries—and for such evidence the student of the letter has little respect. He worships the written word; for the oral, living, tradition from which the word derives force and vitality he has little use. Therefore the written word had to be found. It has taken me some nine or ten years longer to complete the evidence, but the chain is at last linked up, and we can now prove by printed texts the parallels existing between each and every feature of the Grail story and the recorded symbolism of the Mystery cults. Further, we can show that between these Mystery cults and Christianity there existed at one time a close and intimate union, such a union as of itself involved the practical assimilation of the central rite, in each case a ‘Eucharisticc’ Feast, in which the worshippers partook of the Food of Life from the sacred vessels. In face of the proofs which will be found in these pages I do not think any fair-minded critic will be inclined to dispute any longer the origin of the ‘Holy’ Grail; after all it is as august and ancient an origin as the most tenacious upholder of Its Christian character could desire. But I should wish it clearly to be understood that the aim of these studies is, as indicated in the title, to determine the _origin_ of the Grail, not to discuss the _provenance_ and interrelation of the different versions. I do not believe this latter task can be satisfactorily achieved unless and until we are of one accord as to the character of the subject matter. When we have made up our minds as to what the Grail really was, and what it stood for, we shall be able to analyse the romances; to decide which of them contains more, which less, of the original matter, and to group them accordingly. On this point I believe that the table of descent, printed in Volume II. of my _Perceval_ studies is in the main correct, but there is still much analytical work to be done, in particular the establishment of the original form of the _Perlesvaus_ is highly desirable. But apart from the primary object of these studies, and the results therein obtained, I would draw attention to the manner in which the evidence set forth in the chapters on the Mystery cults, and especially that on _The Naassene Document_, a text of extraordinary value from more than one point of view, supports and complements the researches of Sir J. G. Frazer. I am, of course, familiar with the attacks directed against the ‘Vegetation’ theory, the sarcasms of which it has been the object, and the criticisms of what is held in some quarters to be the exaggerated importance attached to these Nature cults. But in view of the use made
