This disposition of mind, altogether so peculiar to the Middle Ages, and which, happily for mankind, has yielded to an improved state of civilization and the diffusion of popular instruction, accounts for the origin and long duration of this extraordinary mental disorder. The good sense of the people recoiled with horror and aversion from this heavy plague, which, whenever malevolent persons wished to curse their bitterest enemies and adversaries, was long after used as a malediction.[63] The indignation also that was felt by the people at large against the immorality of the age was proved by their ascribing this frightful affliction to the inefficacy of baptism by unchaste priests, as if innocent children were doomed to atone, in after years, for this desecration of the sacrament administered by unholy hands. We have already mentioned what perils the priests in the Netherlands incurred from this belief. They now, indeed, endeavored to hasten their reconciliation with the irritated and at that time very degenerate people by exorcisms, which, with some, procured them greater respect than ever, because they thus visibly restored thousands of those who were affected. In general, however, there prevailed a want of confidence in their efficacy, and then the sacred rites had as little power in arresting the progress of this deeply rooted malady as the prayers and holy services subsequently had at the altars of the greatly revered martyr St. Vitus. We may, therefore, ascribe it to accident merely, and to a certain aversion to this demoniacal disease, which seemed to lie beyond the reach of human skill, that we meet with but few and imperfect notices of the St. Vitus' dance in the second half of the fifteenth century. The highly colored descriptions of the sixteenth century contradict the notion that this mental plague had in any degree diminished in its severity, and not a single fact is to be found which supports the opinion that any one of the essential symptoms of the disease, not even excepting the tympany, had disappeared, or that the disorder itself had become milder in its attacks. The physicians never, as it seems, throughout the whole of the fifteenth century, undertook the treatment of the dancing mania, which, according to the prevailing notions, appertained exclusively to the servants of the Church. Against demoniacal disorders they had no remedies, and though some at first did promulgate the opinion that the malady had its origin in natural circumstances, such as a hot temperament, and other causes named in the phraseology of the schools, yet these opinions were the less examined, as it did not appear worth while to divide with a jealous priesthood the care of a host of fanatical vagabonds and beggars.
