The belief that human beings can change themselves, or be changed, into animals carries with it the corollary that wounds received by a person when in the semblance of an animal will remain on the body after the return to human shape. This belief seems to be connected with the worship of animal-gods or sacred animals, the worshipper being changed into an animal by being invested with the skin of the creature, by the utterance of magical words, by the making of magical gestures, the wearing of a magical object, or the performance of magical ceremonies. The witches of the sixteenth and seventeenth centuries appear to have carried on the tradition of the pre-Christian cults; and the stories of their transformations, when viewed in the light of the ancient examples, are capable of the same explanation. Much confusion, however, has been caused by the religious and so-called scientific explanations of the contemporary commentators, as well as by the unfortunate belief of modern writers in the capacity of women for hysteria. At both periods pseudo-science has prevented the unbiassed examination of the material. There are no records extant of the animals held sacred by the early inhabitants of Great Britain, but it is remarkable that the range of the witches' transformations was very limited; cats and hares were the usual animals, occasionally but rarely dogs, mice, crows, rooks, and bees. In France, where the solemn sacrifice of a goat at the Sabbath points to that animal being sacred, it is not surprising to find both men and women witches appearing as goats and sheep. Unless there were some definite meaning underlying the change of shape, there would be no reason to prevent the witches from transforming themselves into animals of any species. It would seem then that the witches, like the adorers of animal gods in earlier times, attempted to become one with their god or sacred animal by taking on his form; the change being induced by the same means and being as real to the witch as to Sigmund the Volsung[894] or the worshipper of Lycaean Zeus.[895] In the earlier cults the worshipper, on becoming an animal, changed his outward shape to the eye of faith alone, though his actions and probably his voice proclaimed the transformation. The nearest approach to an outward change was by covering the body with the skin of the animal, or by wearing a part of the skin or a mask. The witches themselves admitted that they were masked and veiled, and the evidence of other witnesses goes to prove the same. Boguet suggests that the disguise was used to hide their identity, which was possibly the case at times, but it seems more probable, judging by the evidence, that the masking and veiling were for ritual purposes.
