Among those who were so far beyond their age that the truths they proclaimed not only were rejected by the majority but brought them into danger was Dr. John Weyer, the first serious opponent of the witch mania. He stood almost alone. His attack on the witch-hunters, though it marks the turn of the tide, was followed by more than a century of cruelty, injustice, and superstition; yet our ideas on the subject are now so entirely altered that it is hard to imagine the value and danger of the service he performed, and his name was almost forgotten even by members of his own profession, when his biography was published by Dr. K. Binz in 1885.[265] Let us try to get some idea of the nature of the witch mania, that we may better appreciate the courage and intelligence of this ancient physician. In the second half of the fifteenth century a new age began in Western Europe. The revival of Greek, the invention of printing, and the discovery of America gave fresh ideas and new prospects to mankind. But, as the sun’s rays were believed to breed serpents in fermenting matter, so amid this ferment of new life and light rose a hideous monster, more terrible than any fabled dragon of romance or superstition of the darkest ages, which for generations satiated itself on the tears and blood of the innocent and helpless. This was the witch mania. For two centuries the majority of theologians and jurists in Western Europe were convinced that vast numbers of their fellow creatures, especially women, were in league with the devil, that they had sexual intercourse with him or his imps, and that he bestowed on them in exchange for their souls the power of injuring their neighbours in person or property. They thought it their duty to search out these witches, to force from them, by the most terrible tortures they could devise, not only confessions of their own guilt, but also denunciations of their associates, and finally to put them to death, preferably by burning. In consequence, many thousands of innocent persons of all ages and ranks, but especially poor women, were judicially murdered, after being first compelled by unspeakable torments to commit moral suicide by declaring themselves guilty of unmentionable crimes, and to involve their dearest friends and relations in a similar fate. There is no sadder scene in the whole tragicomedy of human history. There had been nothing like it in the darkest of the dark ages, there was nothing like it among the far more ignorant and superstitious adherents of the Eastern Church. The witch mania in its extreme form has been manifested only by the Catholics and Protestants of the sixteenth and seventeenth centuries and by some tribes of African savages.
