It would be easy to think that these hospitals were rudely built, were badly ventilated, were ill-arranged and, above all, were likely to be houses for the perpetuation of disease rather than for the regaining of health. We are prone to think that we are the first generation to solve the problem of hospital construction. We know what poorly-constructed, badly-planned institutions were the hospitals of three generations ago. What, then, must have been the hospital buildings of centuries ago? This argument has no place in history; the worst hospitals in the world and in history were erected at the end of the eighteenth and the beginning of the nineteenth century. Some of the best hospitals ever constructed date from the thirteenth, fourteenth and fifteenth centuries. This was a time when great architects were successfully solving the construction problems for cathedrals, municipal buildings, colleges and the like, and they solved them quite as successfully for hospitals. Some of these hospitals were models in their way. One of them, built toward the end of the thirteenth century, by the sister of St. Louis, Marguerite of Bourgogne, with its large windows high in the walls, in single-story buildings, with arrangements for the segregation of patients, with the kitchens in a separate building, with beautiful {130} frescoes on the walls so that patients' minds might be occupied and not left to their own often disturbing devices as with our bare wall, with a stream of running water divided so as to pass on both sides of the hospital, is a model of construction for all time. It was in surgery rather than medicine, however, that these great mediaeval university medical schools left their impress upon the history of medicine. During the thirteenth, fourteenth and fifteenth centuries we have a series of wonderful teachers of surgery, whose achievements we know not by tradition nor by fragments of their writings, but by the text-books which they wrote and which constituted the teaching for generations and sometimes for centuries after their time. Gurlt, the great German historian of surgery, devotes some 300 pages of the first volume of his "History of Surgery" to the surgical accomplishments of the Middle Ages. He even protests that space compels him to abbreviate the story of what these old-time masters of surgery did to lay the foundation of modern surgical practices. It is a commonplace in the American writing of history that there was no surgery at this time. President White says that, "for over a thousand years surgery was considered dishonorable until the German Emperor Wenceslas, in 1403, ordered that it should be held in honor again." The two centuries immediately preceding this date represent the {131} greatest period in the history of surgery down to our own time, and because of its originality probably greater in real achievement than even our vaunted age.
