Another illustration of adaptability is seen in the rites at wells or rocks common all over Europe. What may have been the original cause of the sacredness of a well or a rock, what may have been the original intention of the processions, the dances and the decorations we have of course no means of knowing. We may guess that some peculiarity in the shape of the rock, the sweet or healing waters of the fountain, or some sudden and unexplained or untoward incident first called and concentrated popular attention, and that a precise, intelligible meaning may hardly have been attached to the few and simple ceremonies first performed. In course of time, we may conjecture, ritual and belief were elaborated and defined. However this may be, we know that before the end of paganism--at {152} least in those countries of the west where inscriptions have been preserved--a spirit or god was believed to haunt the place and to preside over the rites of which it was the scene. To him they were addressed, and it was his favour they sought to conciliate. Christianity came and diverted the rites to new objects, not altogether forbidding, but baptizing them, in accordance with the policy enunciated in Pope Gregory’s famous letter to the Abbot Mellitus. All these changes necessitate adaptations of practice. That which at first was formless receives a definite form. That which may have been an indeterminate expression of awe and reverence becomes distinctly worship, though not without elements, often retained to the last, that we should call magical. And the changes in the nominal objects of worship are accompanied by progressive changes in the details of the ritual. Lastly when, as in many cases, official recognition of the ritual is abandoned, and it is left to the unguided superstition of the peasant, it tends to slip back into its original indeterminate condition. Acts are performed or avoided, and ceremonies undertaken, not as worship of a power known and resident on the hallowed spot, but for benefits sometimes precise, more often for luck mysterious, impersonal, half-credited, or from fear of something equally mysterious, but for that reason all the more terrible. Beyond this, the practices linger into a stage, unknown to the savages who began them, where they are performed for pleasure, or else in the hope of monetary gain, by children and adolescents, and die away gradually under the stress of modern life and the influence of the schoolmaster. The earlier stages of this round may, as we have seen, be observed occasionally in the rites of peoples still in the lower culture. Close observation, accurate analysis and {153} comparison would probably result in finding them more frequently. Meanwhile let us turn to another question.
