Never did the far-famed sanctuary of the god of medicine in Epidaurus witness such an influx of invalids as gathered in the hospitals of Salerno and pressed through the streets of the Hippocratic city, seeking the aid of those doctors whose marvelous cures had given them a world-wide reputation. Small wonder, then, that the _Regimen Santatis Salernitanum_--that famous code of health of the school of Salerno--has been translated into almost all the languages of modern Europe, and that since 1480 no fewer than two hundred and fifty editions of it have been published. "Not to have been familiar with it from beginning to end, not to have been able to quote it orally as occasion might require, would, during the Middle Ages, have cast serious suspicion upon the professional culture of any physician."[194] But the noblest claims of the Hippocratic city to the gratitude of humanity yet remain to be told. A German traveler in the thirteenth century wrote: "Laudibus aeternum nullum negat esse Salernum Illuc pro morbis totus circumfluit orbis."[195] This was because Salerno was universally recognized as the "day star" and "morning glory" of the best culture in the healing art, and, still more, because of the thorough instruction she gave in her schools of medicine and the preeminence she so long held in every department of medical lore. The course of study in medicine was long and thorough, and the candidate applying for a degree had to pass a rigid examination and give proof not only of his proficiency in every branch of the healing art, but also of perfect acquaintance with the various branches of science and letters as well. At the time of Frederick II, who organized all the different schools of Salerno into a single university, a three years' course in philosophy and literature was required before one could present himself for entrance into the school of medicine. The courses in medicine lasted five years, at least, after which a year of practice with an old physician was required. In addition to this, if the candidate wished to practice surgery he was obliged to devote one year to the study of human anatomy and to the dissection of human bodies. Considering the progress of knowledge since the time of Frederick II, it must be admitted that the legal requirements enforced by the faculty of Salerno compare favorably with those of the best of our medical schools of to-day.
