Wherefore, in spite of all the learning and ingenuity brought to bear against it, I avow myself an impenitent believer in Sir J. G. Frazer's main theory, and as I have said above, I hold that theory to be of greater and more far-reaching importance than has been hitherto suspected.
I would add a few words as to the form of these studies--they may be found disconnected. They have been written at intervals of time extending over several years, and my aim has been to prove the essentially archaic character of all the elements composing the Grail story rather than to analyse the story as a connected whole. With this aim in view I have devoted chapters to features which have now either dropped out of the existing versions, or only survive in a subordinate form, e.g. the chapters on The Medicine Man, and The Freeing of the Waters. The studies will, I hope, and believe, be accepted as offering a definite contribution towards establishing the fundamental character of our material; as stated above, when we are all at one as to what the Holy Grail really was, and is, we can then proceed with some hope of success to criticize the manner in which different writers have handled the inspiring theme, but such success seems to be hopeless so long as we all start from different, and often utterly irreconcilable, standpoints and proceed along widely diverging roads. One or another may, indeed, arrive at the goal, but such unanimity of opinion as will lend to our criticism authoritative weight is, on such lines, impossible of achievement.
As a first step towards the successful prosecution of an investigation into the true nature and character of the mysterious object we know as the Grail it will be well to ask ourselves whether any light may be thrown upon the subject by examining more closely the details of the Quest in its varying forms; i.e., what was the precise character of the task undertaken by, or imposed upon, the Grail hero, whether that hero were Gawain, Perceval, or Galahad, and what the results to be expected from a successful achievement of the task. We shall find at once a uniformity which assures us of the essential identity of the tradition underlying the varying forms, and a diversity indicating that the tradition has undergone a gradual, but radical, modification in the process of literary evolution. Taken in their relative order the versions give the following result.
