GREAT SURGEONS OF THE MEDIEVAL UNIVERSITIES
Strange as it may appear to those who have not watched the development of our knowledge of the Middle Ages in recent years the most interesting feature in the medical departments and, indeed, of the post-graduate work generally of the medieval universities, is that in surgery. There is a very general impression that this department of medicine did not develop until quite recent years, and that particularly it failed to develop to any extent in the Middle Ages. A good many of the historians of this period, indeed, though never the special historians of medicine, have even gone far afield in order to find some reason why surgery did not develop at this time. They have insisted that the Church by its prohibition of the shedding of blood, first to monks and friars, and then to the secular clergy, prevented the normal development of surgery. Besides they add that Church opposition to anatomy completely precluded all possibility of any genuine natural evolution of surgery as a science.
There is probably no more amusing feature of quite a number of supposedly respectable and presumably authoritative historical works written in English than this assumption with regard to the absence of surgery during the later Middle Ages. Only the most complete ignorance of the actual history of medicine and surgery can account for it. The writers who make such assertions must never have opened an authoritative medical history. Nothing illustrates so well the expression of the editors of the "Cambridge Modern History" referred to more than once in these pages that "in view of changes and of gains such as these [the jointing of original documents] it has become impossible for historical writers of the present day to trust without reserve even to the most respected secondary authority. The honest student finds himself continually deserted, retarded, misled by the classics of historical literature." Fortunately for us this sweeping condemnation does not hold to any great extent for the medical historical classics. All of the classic historians of medicine tell us much of the surgery of the thirteenth and fourteenth centuries, and in recent years the republication of old texts and the further study of manuscript documents of various kinds have made it very clear that there is almost no period in the history of the world when surgery was so thoroughly and successfully cultivated as during the rise and development of the universities and their medical schools in the thirteenth and fourteenth centuries.
It is interesting to trace the succession of great contributors to surgery during these two centuries. We know their teaching not from tradition, but from their text-books so faithfully preserved for us by their devoted students, who must have begrudged no time and spared no labor in copying, for many of the books are large, yet exist in many manuscript copies.
Modern surgery may be said to owe its origin to a school of surgeons, the leaders of whom were educated at Salerno in the early part of the thirteenth century, and who, teaching at various north Italian universities, wrote out their surgical principles and experiences in a series of important contributions to that department of medical science. The fact that the origin of the school was at Salerno, where, as is well known, Arabian influence counted for much and for which Constantine's translations of Arabian works proved such a stimulus a century before, makes most students conclude that this later medieval surgical development is simply a continuation of the Arabian surgery that, as we have seen, developed very interestingly during the earlier Middle Ages. Any such idea, however, is not founded on the realities of the situation, but on an assumption with regard to the extent of Arabian influence. Gurlt in his "History of Surgery" (Vol. I, page 701) completely contradicts this idea, and says with regard to the first of the great Italian writers on surgery, Rogero, that "though Arabian works on surgery had been brought over to Italy by Constantine Africanus a hundred years before Roger's time, these exercised no influence over Italian surgery in the next century, and there is scarcely a trace of the surgical knowledge of the Arabs to be found in Roger's works."
It is in the history of medicine particularly that it is possible to trace the true influence of the Arabs on European thought in the later Middle Ages. We have already seen in the chapter on Salerno that Arabian influence did harm to Salernitan medical teaching. The school of Salerno itself had developed simple, dietetic, hygienic, and general remedial measures that included the use of only a comparatively small amount of drugs. Its teachers emphasized nature's curative powers. With Arabian influence came polypharmacy, distrust of nature, and attempts to cure disease rather than help nature. In surgery, which developed very wonderfully in the thirteenth and fourteenth centuries, Salerno must be credited with the incentive that led up to the marvellous development that came. With this, however, Arabian influence has nothing to do. Gurlt, besides calling attention to the fact that the author of the first great text-book on the subject not only did not draw his inspiration from Arab sources, insisted that "instead of any Arabisms being found in his [Roger's] writings many Græcisms occur." The Salernitan school of surgery drank at the fountain-head of Greek surgery. Apart from Greek sources Roger's book rests entirely upon his own experiences, those of his teachers and his colleagues, and the tradition in surgery that had developed at Salerno. This tradition was entirely from the Greek. Roger himself says in one place, "We have resolved to write out deliberately our methods of operation such as they have been derived from our own experience and that of our colleagues and illustrious men."
