“Sorcier est celuy qui par moyens Diaboliques sciemment s’efforce de paruenir a quel que chose.” (“A sorcerer is one who by commerce with the Devil has a full intention of attaining his own ends.”) With these words the profoundly erudite jurisconsult Jean Bodin, one of the acutest and most strictly impartial minds of his age, opens his famous _De la Demonomanie des Sorciers_,[1] and it would be, I imagine, hardly possible to discover a more concise, exact, comprehensive, and intelligent definition of a Witch. The whole tremendous subject of Witchcraft, especially as revealed in its multifold and remarkable manifestations throughout every district of Southern and Western Europe from the middle of the thirteenth until the dawn of the eighteenth century,[2] has it would seem in recent times seldom, if ever, been candidly and fairly examined. The only sound sources of information are the contemporary records; the meticulously detailed legal reports of the actual trials; the vast mass of pamphlets which give eye-witnessed accounts of individual witches and reproduce evidence _uerbatim_ as told in court; and, above all, the voluminous and highly technical works of the Inquisitors and demonologists, holy and reverend divines, doctors _utriusque iuris_, hard-headed, slow, and sober lawyers,—learned men, scholars of philosophic mind, the most honourable names in the universities of Europe, in the forefront of literature, science, politics, and culture; monks who kept the conscience of kings, pontiffs; whose word would set Europe aflame and bring an emperor to his knees at their gate. It is true that Witchcraft has formed the subject of a not inconsiderable literature, but it will be found that inquirers have for the most part approached this eternal and terrible chapter in the history of humanity from biassed, although wholly divergent, points of view, and in consequence it is often necessary to sift more or less thoroughly their partial presentation of their theme, to discount their unwarranted commentaries and illogical conclusions, and to get down in time to the hard bed-rock of fact.
