It has been usual in modern times to regard the persecution of the witches as a proof of the barbarous intolerance of the ancient Church; but, in truth, a careful examination of the evidence leaves no room for doubting that witchcraft was only the cloak of real vices. Most of the persons who were burned in France as sorcerers had really used the popular belief in magic to hide their own debaucheries, and had succeeded in depraving large numbers of youth of both sexes. It was stated by a theological writer of the time of Francis I., that in his day there were one hundred thousand persons sold to Satan in France.[183] Allowing for some exaggeration, it must still be inferred from this statement that this form of prostitution had assumed alarming proportions. Nor is there any good reason for doubting but priests and other persons of lewd propensities turned the simplicity of the village girls to account in very many instances, and richly earned the severe penalty that was inflicted upon them by the arm of the Church. The vigil, or _sabat_, disappears from history during the sixteenth century. That it had been for some time before its extinction a haunt of debauchees and a fertile source of prostitution, the writers on demonology and the old chroniclers establish incontrovertibly. Other aids to prostitution were obtained from the very ranks of the Church. During the Middle Ages numbers of strange sects appeared, many of which relied for success on the favor they allowed to sensuality. At the present day it is not easy to determine what proportion of the stories that are in print respecting many of these sects were the fruit of sectarian jealousy on the part of their rivals; some of them were doubtless calumniated, but there are others about whose character and practices there is no room for controversy. The Flagellants, for instance, who counted eight hundred thousand proselytes in France in the fourteenth century, were unquestionably depraved. They marched in procession, men and women together, through the cities of France, each member of the society using the whip freely on the bare back of the person before him; and at night they assembled in country places, and proceeded to more serious flagellations. The opinion of learned persons ascribed erotic effects to these flagellations, it being said, apparently with truth, that when the flagellants had excited their senses by their discipline, they gave way to frantic debauchery. However this be, it is plain that the spectacle of naked men and women marching in procession and scourging one another can not but have been provocative of prostitution.[184]
