Old-Time Makers of Medicine / The Story of The Students And Teachers of the Sciences Related to Medicine During the Middle Ages

by James J. Walsh

Less than this could scarcely have been expected from the medical school which brought such an uplift of professional dignity and advance in the standards of medical education that are to be noticed in connection with Salerno. Registration, licensure, preliminary education, adequate professional studies, clinical experience under expert guidance, even special training for surgical work, all came in connection with this great medical school. Such practical progress in medical education could not have been made but by men who faced the problems of the practice of medicine without self-deception and solved them as far as possible by common-sense, natural, and rational methods.

It is usually said that at Salerno surgery occupied an inferior position. It is true that we have less record of it in the earlier years of Salerno than we would like to see. It was somewhat handicapped by the absence of human dissection. This very important defect was not due to any Church opposition to anatomy, as has often been said, but to the objection that people have to seeing the bodies of their friends or acquaintances used for anatomical purposes. In the comparatively small towns of the Middle Ages there were few strangers, and therefore very seldom were there unclaimed bodies. The difficulty was in the obtaining of dissecting material. We had the same difficulty in this country until about two generations ago, and the only way that bodies could be obtained regularly was by "resurrecting" them, as it was called, from graveyards. In the absence of human subjects, anatomy was taught at Salerno upon the pig. The principal portion of the teaching in anatomy consisted of the demonstration of the organs in the great cavities of the body and their relations, with some investigations of their form and the presumed functions of the corresponding organs in man. Copho's well-known "Anatomy of the Pig" was a text-book written for the students of Salerno. In spite of its limitations, it shows the beginnings of rather searching original inquiry and even some observations in pathological anatomy. It is simple and straightforward and does not profess to be other than it is, though it must be set down as the first reasonably complete contribution to comparative anatomy.

When their surgery came to be written down, however, it gave abundant evidence of the thoroughness with which this department of medicine had been cultivated by the Salernitan faculty. We have the text-book of Roger, with the commentary of Rolando, and then the so-called commentary of the Four Masters. These writings were probably made rather for the medical school at Bologna than that of Salerno, though there is no doubt that at least Roger and Rolando received their education at Salerno and embodied in their writings the surgical traditions of that school. While I have preferred, in order to have a connected story of surgical development, to treat of their contributions to their specialty under the head of the "Great Surgeons of the Medieval Universities," it seems well to point out here that they must be considered as representing especially the surgical teaching of the older medical school of Salerno. There are many interesting features of the old teaching that they have embodied in their books. For instance, at Salerno both sutures and ligatures were employed in order to prevent bleeding. We are rather accustomed to think of such uses of thread, and especially the ligature, as being much later inventions. The fact of the matter is, however, that ligatures and sutures were reinvented over and over again and then allowed to go out of use until someone who had no idea of their dangers came to reinvent them once more.[8]

Much is often said about the place of Arabian surgery and medicine at this time, and the influence that they had over the medical teaching and thinking of the period. To trust many of the shorter histories of medicine the Arabs must be given credit for more of the medical thought of this time than any other medical writers or thinkers. It is forgotten, however, apparently, that in the southern part of Italy, where Salerno was situated, Greek influence never died out. This had been a Greek colony in the olden time and continued to be known for many centuries after the Christian era as Magna Græcia. Greek medicine, then, had more influence here than anywhere else. As a matter of fact, the beginnings of Salernitan teaching are all Greek and not at all Arabian. This is as true in surgery as in medicine. I have quoted Gurlt in the chapter on "Great Surgeons of the Medieval Universities," insisting that the Salernitan school owed nothing at all to Arabian surgery. Salernitan medicine was, during the twelfth century, just as free from Arabian influence. When Arabian medicine makes itself felt, as pointed out by Pagel in his "Geschichte der Heilkunde im Mittelalter,"[9] far from exerting a beneficial influence, it had a rather unfortunate effect. It led especially to an oversophistication of medicine from the standpoint of drug therapeutics. The Arabian physicians trusted nature very little. In this they were like our forefathers of medicine one hundred years ago, of whom Rush was the typical representative—so history repeats itself.

Before the introduction of Arabian medicine the Salernitan school of medicine was noted for its common-sense methods and its devotion to all the natural modes of healing. It looked quite as much to the prevention of disease as its treatment. Diet and air and water were always looked upon as significant therapeutic aids. With the coming of Arabian influence there began, says Pagel, "as the literature of the times shows very well, that rule of the apothecary in therapeutics which was an unfortunate exaggeration. Now all the above-mentioned complicated prescriptions came to be the order of the day. Apparently the more complicated a prescription the better. Dietetics especially was relegated to the background. Salerno, at the end of the twelfth century, had already reached its highest point of advance in medicine and was beginning to decline. Decadence was evident in so far as all the medical works that we have from that time are either borrowings or imitations from Arabian medicine with which eventually Salernitan medical literature became confounded. Only a few independent authors are found after this time." This is so very different from what is ordinarily presumed to have been the case and openly proclaimed by many historians of medicine because apparently they would prefer to attribute scientific advance to the Arabs than to the Christian scholars of the time, that it is worth while noting it particularly.

Salerno was particularly rich in its medical literary products. Very often we have not the names of the writers. Apparently there is good reason to think that a number of the professors consulted together in writing a book, and when it was issued it was considered to be a text-book of the Salernitan school of medicine rather than of any particular professor. This represents a development of co-operation on the part of colleagues in medical teaching that we are likely to think of as reserved for much later times.

The most important medical writing that comes to us from Salerno, in the sense at least of the work that has had most effect on succeeding generations, has been most frequently transcribed, most often translated and committed to memory by many generations of physicians, is the celebrated Salernitan medical poem on hygiene. The title of the original Latin was "Regimen Sanitatis Salernitanum." It was probably written about the beginning of the twelfth century. A century or so later it came to be the custom to call medical books after flowers, and so we had the "Lilium Medicinæ" and the "Flos Medicinæ" down at Montpellier, and this became the "Flos Medicinæ" of Salerno. Pagel calls it the quintessence of Salernitan therapeutics.

For many centuries portions at least of this Latin medical poem were as common in the mouths of physicians all over Europe as the aphorisms of Hippocrates or the sayings of Galen. Probably this enables us to understand the great reputation that the Salernitan school enjoyed and the influence that it wielded better than anything else. The poem is divided into ten principal parts, containing altogether about 3,500 lines. The first part on hygiene has 855 lines in eight chapters. The second part on materia medica, though containing only four chapters, has also about 800 lines. Anatomy and physiology are crowded into about 200 lines, etiology has something over 200, semiotics has about 250, pathology has but thirty lines more or less, and therapeutics about 400; nosology has about 600 more, and finally there is something about the physician himself, and an epilogue. As Latin verses go, when written for such purposes, these are not so bad, though some of them would grate on a literary ear. The whole work makes a rather interesting compendium of medicine, with therapeutic indications and contra-indications, and whatever the physician of the medieval period needed to have ready to memory. Some of its prescriptions, both in the sense of formulæ and of directions to the patient, have quite a modern air.

One very interesting contribution to medical literature that comes to us from Salerno bears the title, "The Coming of a Physician to His Patient, or An Instruction for the Physician Himself." We have had a number of such works published in recent years, but it is a little surprising to have the subject taken up thus early in the history of modern professional life. It is an extremely valuable document, as demonstrating how practical was the teaching at Salerno. The work is usually ascribed to Archimattheas, and it certainly gives a vivid picture of the medical customs of the time. The instruction for the immediate coming of the physician to his patient runs as follows: "When the doctor enters the dwelling of his patient, he should not appear haughty, nor covetous, but should greet with kindly, modest demeanor those who are present, and then seating himself near the sick man accept the drink which is offered him (sic) and praise in a few words the beauty of the neighborhood, the situation of the house, and the well-known generosity of the family,—if it should seem to him suitable to do so. The patient should be put at his ease before the examination begins and the pulse should be felt deliberately and carefully. The fingers should be kept on the pulse at least until the hundredth beat in order to judge its kind and character; the friends standing round will be all the more impressed because of the delay and the physician's words will be received with just that much more attention."
