“We have found, further, that this close relation between the ruler and his land, which resulted in the ill of one becoming the calamity of all, is no mere literary invention, proceeding from the fertile imagination of a twelfth century court poet, but a deeply rooted popular belief, of practically immemorial antiquity and inexhaustible vitality; we can trace it back thousands of years before the Christian era, we find it fraught with decisions of life and death to-day.
Further, we find in that belief a tendency to express itself in certain ceremonial practices, which retain in a greater or less degree the character of the ritual observances of which they are the survival. Mr E. K. Chambers, in The Mediaeval Stage, remarks: “If the comparative study of Religion proves anything it is, that the traditional beliefs and customs of the mediaeval or modern peasant are in nine cases out of ten but the detritus of heathen mythology and heathen worship, enduring with but little external change in the shadow of a hostile faith.”
“This is notably true of the village festivals and their ludi. Their full significance only appears when they are regarded as fragments of forgotten cults, the naïve cults addressed by a primitive folk to the beneficent deities of field and wood and river, or the shadowy populace of its own dreams 1.”
We may, I think, take it that we have established at least the possibility that in the Grail romances we possess, in literary form, an example of the detritus above referred to, the fragmentary record of the secret ritual of a Fertility cult.”
