Sir G.L. Gomme supports the theory that the Druids were a pre-Celtic priesthood, because, in his opinion, much of their belief in magic as well as their use of human sacrifice and the redemption of one life by another, is opposed to "Aryan sentiment." Equally opposed to this are their functions of settling controversies, judging, settling the succession to property, and arranging boundaries. These views are supported by a comparison of the position of the Druids relatively to the Celts with that of non-Aryan persons in India who render occasional priestly services to Hindu village communities.[1008] Whether this comparison of occasional Hindu custom with Celtic usage two thousand years ago is just, may be questioned. As already seen, it was no mere occasional service which the Druids rendered to the Celts, and it is this which makes it difficult to credit this theory. Had the Celtic house-father been priest and judge in his own clan, would he so readily have surrendered his rights to a foreign and conquered priesthood? On the other hand, kings and chiefs among the Celts probably retained some priestly functions, derived from the time when the offices of the priest-king had not been differentiated. Cæsar's evidence certainly does not support the idea that "it is only among the rudest of the so-called Celtic tribes that we find this superimposing of an apparently official priesthood." According to him, the power of the Druids was universal in Gaul, and had their position really corresponded to that of the pariah priests of India, occasional priests of Hindu villages, the determined hostility of the Roman power to them because they wielded such an enormous influence over Celtic thought and life, is inexplainable. If, further, Aryan sentiment was so opposed to Druidic customs, why did Aryan Celts so readily accept the Druids? In this case the receiver is as bad as the thief. Sir G.L. Gomme clings to the belief that the Aryans were people of a comparatively high civilisation, who had discarded, if they ever possessed, a savage "past." But old beliefs and customs still survive through growing civilisation, and if the views of Professor Sergi and others are correct, the Aryans were even less civilised than the peoples whom they conquered.[1009] Shape-shifting, magic, human sacrifice, priestly domination, were as much Aryan as non-Aryan, and if the Celts had a comparatively pure religion, why did they so soon allow it to be defiled by the puerile superstitions of the Druids?
