It is no less a person than Virchow, the greatest of modern medical scientists, who has traced the origins of the modern German city hospitals back to Innocent and given us a list of those which were established during the century following his pontificate. Here are the names of those towns from Virchow's list in which hospitals were founded during the thirteenth century in Germany alone, which will show very convincingly how widespread the hospital establishment movement was: Zurich, St. Gallen, Bern, Basel, Constanz, Villingen, Pfullendorf, Freiburg, Breisch, Stephansfelden, Oppenheim, Mainz, Speyer, Coblenz (an der Leer), Cologne, Crefeld, Ulm, Biberach, Rothenburg, Kirchheim, Mergentheim, Wimpfen, Reutlingen, Memmingen, Augsburg, Rothenburg a. Tauber, München, Frankfort a. M., {252} Hoxter, Dortmund, Brandenburg, Spandau, Salzwedel, Stendal, Berlin, Perleberg, Pritzwalk, Halberstadt, Halle, Quedlinburg, Helmstedt, Magdeburg, Sangerhauson, Eisenach, Naumburg, Hanover, Gottingen, Northeim, Bremen, Hamburg, Lübeck, Parchim, Wismar, Rostock, Schwerin, Mollen, Oldeslo, Ratzelburg, Ribnitz, Stettin, Stralsund, Greifswald, Demmin, Anclam, Breslau, Bunzlau, Gorlitz, Brieg, Glatz, Sagan, Steinau, Glogau, Inowraclaw, Wien, Meran, Brixen, Sterzing, Elbing, Thorn, Königsberg, Danzig, Marienburg, Riga. Many of these towns were comparatively small. In fact, there were no cities that we moderns would call large in the thirteenth century. London had probably not more than some twenty thousand; Paris, even at the most flourishing period of the university, under fifty thousand. Most of the German towns had less than ten thousand, and of these which are the sites of hospital foundations mentioned by Virchow, probably not more than a dozen, if that many, had more than five thousand inhabitants. Since the movement spread even to such small towns, it can be readily understood how far-reaching in its effects was the policy initiated by Innocent III. and how thoroughly he laid the secure foundations of a great Christian hospital system.
