Indeed, for more than six hundred years, they had no physicians, but employed theurgic methods of treatment by means of prayers, charms, and prescriptions from the ancient Sibylline Books, which were reputed to date from the reign of Tarquin the Proud, in the sixth century B. C. These volumes were kept in a stone chest, under ground, in the Temple of Jupiter Capitolinus at Rome. The ancient Romans possessed only the rude surgery and domestic medicine of the barbarians, until the importation of scientific methods from Greece. Cato the Censor (B. C. 234-149) disliked physicians, partly because they were mostly Greeks, and partly because he himself, although venerated as a model of Roman virtue, was an outrageous quack, who thought himself equal to a whole college of physicians.[212:1] From a very early time, and for many centuries, medical pretenders and empirics were known as "magicians." Practitioners of this class throve exceedingly during the reigns of several Roman emperors. They strove to work upon the imaginations of the people by sensational curative methods. Inasmuch, wrote Dr. Hugo Magnus, as whatever is curious and unusual, has always possessed a special fascination for humanity, the incredible remedies of the magicians found everywhere hosts of believers. And as the most nonsensical theories, if well tinged with the miraculous, find eager credence, there developed a rude form of psycho-therapy. For by the employment of extraordinary and even loathsome substances, many of which had no value as material remedies, they sought to impress curative ideas upon the minds of their patients, and doubtless very often with success. Inventive genius must have been sorely taxed among the magicians, in their endeavors to originate sensational prescriptions. The voluminous works of Alexander of Tralles, Quintus Serenus Samonicus, Marcellus Empiricus, and of many others, show how close was the union between medicine and magic. An enumeration of uncouth remedies formerly in vogue would fill huge pharmacopœias, and belongs to the domain of Folk-Medicine. Let one or two examples suffice here. For the removal of those hardened portions of the epidermis, usually occurring upon the feet, and vulgarly known as corns, Pliny the Elder, in his "Natural History," recommends the sufferer, after observing the flight of a meteor, to pour a little vinegar upon the hinge of a door. And Sextus Placitus Papyriensis, a nonsensical medical writer of the fourth century, advises, for the cure of glaucoma, that the affected eye be rubbed with the corresponding organ of a wolf.
