There dwelt a physician in Zwickau—we no longer know the name of this estimable man—who, full of zeal for the good of mankind, opposed this destructive folly. He went from house to house, and wherever he found a patient buried in a hot bed, dragged him out with his own hands, everywhere forbad that the sick should thus be tortured with heat, and saved by his decisive conduct, many, who but for him, must have been smothered like the rest[612]. It often happened, at this time, that amidst a circle of friends, if the Sweating Sickness was only brought to mind by a single word, first one, and then another was seized with a tormenting anguish, their blood curdled, and certain of their destruction, they quietly slunk away home, and there actually became a prey to death[613]. This mortal fear is a heavy addition to the scourge of rapidly fatal epidemics, and is, properly speaking, an inflammatory disease of the mind, which, in its proximate effects upon the spirits, bears some resemblance to the nightmare. It confuses the understanding, so as to render it incapable of estimating external circumstances according to their true relations to each other; it magnifies a gnat into a monster, a distant improbable danger into a horrible spectre which takes a firm hold of the imagination; all actions are perverted, and if during this state of distraction, any other disease break out, the patient conceives that he is the devoted victim of the much dreaded epidemic, like those unfortunate persons, who, having been bitten by a harmless animal, nevertheless become the subjects of an imaginary hydrophobia. Thus, during the calamitous autumn of 1529, many may have been seized with only an imaginary Sweating Sickness, and under the towering heap of clothing on their loaded beds have met with their graves[614]. Others among these brain-sick people who had the good fortune to remain exempt from bodily ailments, many of them even boasting of their firmness, fell, through the violent commotions in their nerves, into a state of chronic hypochondriasis, which, under circumstances of this sort, is marked by shuddering, and a feeling of uneasiness and dread at the bare mention of the original cause of terror, even when there is no longer any trace of its existence[615]. A person thus disordered in his mind, was recently seen to destroy himself[616] on receiving false intelligence of the return of the late epidemic; thus betraying conduct even more dastardly than those cowardly soldiers, who, when the cannon begin to roar, inflict on themselves slight wounds that they may avoid sharing the dangers of the battle.
