later prose form that we find any suggestion of a Grail Chapel, whereas were the source of the story really to be found in the Mass, such a feature would certainly have had its place in the earliest versions. But in each and all these cases the solution proposed has no relation to other features of the story; it is consequently of value _in_, and _per se_, only, and cannot be regarded as valid evidence for the source of the legend as a whole. In the process of transmutation from Ritual to Romance, the kernel, the Grail legend proper, may be said to have formed for itself a shell composed of accretions of widely differing _provenance_. It is the legitimate task of criticism to analyse such accretions, and to resolve them into their original elements, but they are accretions, and should be treated as such, not confounded with the original and essential material. After upwards of thirty years spent in careful study of the Grail legend and romances I am firmly and entirely convinced that the root origin of the whole bewildering complex is to be found in the Vegetation Ritual, treated from the esoteric point of view as a Life-Cult, _and in that alone_. Christian Legend, and traditional Folk-tale, have undoubtedly contributed to the perfected romantic _corpus_, but they are in truth subsidiary and secondary features; a criticism that would treat them as original and primary can but defeat its own object; magnified out of proportion they become stumbling-blocks upon the path, instead of sign-posts towards the goal. CHAPTER XII Mithra and Attis The fact that there was, at a very early date, among a certain sect of Christian Gnostics, a well-developed body of doctrine, based upon the essential harmony existing between the Old Faith and the New, which claimed by means of a two-fold Initiation to impact to the inner circle of its adherents the secret of life, physical and spiritual, being, in face of the evidence given in the previous chapter, placed beyond any possible doubt, we must now ask, is there any evidence that such teaching survived for any length of time, or could have penetrated to the British Isles, where, in view of the priority of the _Bleheris-Gawain_ form, the Grail legend, as we know it, seems to have originated? I think there is at least presumptive evidence of such preservation, and transmission. I have already alluded to the close connection existing between the Attis cult, and the worship of the popular Persian deity, Mithra, and have given quotations from Cumont illustrating this connection; it will be worth while to study the question somewhat more closely, and discover, if possible, the reason for this intimate alliance. On the face of it there seems to be absolutely no reason for the connection of these cults; the two deities in no way resemble each other; the stories connected with them have no possible analogy; the root conception is widely divergent.
