with the tilling of the soil then extended their influence beyond the limits of vegetation cults proper and became universal elements of the deity cults. The powers shared by the numerous demoniacal beings of the more primitive cults were now centralized in a _single_ goddess mother. The life-giving activity of the deity in connection with human procreation came to be of focal interest. The exaggerated development of cult ecstasy caused the orgy to become a form of self-mortification. The cult associates, especially the priests, lacerated and emasculated themselves in the fury of religious excitement. By becoming a permanent custom, this gave rise to a group of eunuchs consecrated to the service of the deity. These were doubtless the earliest eunuchs of history. In the guardians of Turkish harems and in the singers of the Sistine Chapel, survivals of these unrestrained cults of the past still exist. Now, when the group of emasculated priests paced beside the chariot of the goddess, they might easily have hit upon the idea of hitching a castrated animal to the wagon. But, however plausible this hypothesis may appear, in that it avoids the impossible assumption of an invention, it nevertheless leaves one question unanswered. Even though the castration of the priest may be understood as the result of the well-known effects of extreme religious excitement, the castration of the bull is not yet accounted for. Are we to suppose that the priest merely aimed to render the animal similar to himself? Neither ecstasy nor reflection could account for such a purpose. But there is another factor which has always been significant for cult, and which attained to increased importance precisely in the worship of the deity. I refer to _sacrifice_. In its highest stages, sacrifice assumes new forms, in that man offers either himself or parts of his own body, his blood, his hair, or a finger. A late survival of such sacrifices is to be found in a custom that is still prevalent in Catholic countries. Here it frequently occurs that a sick man lays a wax replica of the diseased part of his body upon the altar of the saint. This idea of sacrificing parts of one's own body is also exemplified in the self-emasculation practised by the Russian sect of Skopzi even in our own Christian age. Such sacrifice, moreover, may receive a wider application, so as to include, among the sacrificial objects, parts of the animal. Now at one time the kidneys with their connected organs were regarded as vehicles of the soul, and, as such, were sacrificed to the gods. The castration of the bull, therefore, may originally well have been regarded as the sacrifice of the most readily accessible of the favourite vehicles of the soul. Thus, it may have been in the case of the animal whose generative organs had been sacrificed to the deity that man first observed the change of characteristics which fitted the animal to be hitched to the chariot of the deity, and finally, through an extension
