The subtleties of theologic interpretation soon evolved a more comprehensive method of dealing with the “possessor” and the possessed. As an appeal to pride was ineffectual and noxious drugs unavailing, it was found necessary to whip the devil out, or the unfortunate individuals were imprisoned, and as a refinement of this treatment they were even tortured. Thus the jailer for a long time played the part of a specialist in lunacy, with the clergy in consultation. Places in which the insane were confined were known as “fool towers” and “witch towers.” This state of things was not altered with the dawn of the Reformation. The writings of Luther conclusively show his ideas in regard to possession and witchcraft, and these views under Calvin reached enormous development. Even Cotton Mather, in many respects far in advance of his times, and who himself had known persecution, was not emancipated from these delusions, and Salem has many a story to tell of possession and witch-baiting. It is true we may quite properly consider these views as the thought of the times, but, in many other respects, Luther, Calvin, and Mather were in advance of their period, and, therefore, a justification for their actions is not quite apparent. Marcus Aurelius also was much superior to his age, yet was grateful to his teachers that they taught him to disregard superstition in all its various forms. It is not unlikely that conditions of this kind frequently led to epidemics—if not of actual insanity, at least to hysteria—which not rarely developed in cities, nunneries, and monasteries; thus the epidemics in Erfurt in 1237, in the Rhine countries in 1374, and many others (see Hirsch). It is rather remarkable that while such views and practises prevailed in the Christian Church, the followers of Mohammed not only held different views, but adopted a mode of treatment of the insane which laid the foundation of modern therapeutics in diseases of the mind. In the twelfth century, in Bagdad, a palace called the “Home of Mercy” was built, in which the insane were confined, examined every month, and released as soon as they had recovered. An asylum in Cairo was founded in 1304, while the first Christian asylum expressly for the mad is noted in 1409 (Lecky). But science fought its way through the barriers of ignorance, misdirected zeal, and superstition. Altho there were physicians and “magicians,” who conformed to the views of the Church, the seed sown by the earlier schools of medicine slowly but surely began to put forth shoots, and the result was a tree of knowledge, the fruit of which may be observed in every modern insane asylum of the world, where the unfortunate sufferer is treated with kindness and skill, which, fortunately, often results in cure.
