It is no wonder, then, that practically all the ecclesiastical visitors who came in such numbers to Rome, made it a custom at this time to attend one or more of Columbus's anatomical lectures. They were looked upon as one of the features of the Roman university life of the time. How much good was accomplished by this can scarcely be estimated. The example must have had great influence especially on members of faculties of various educational institutions who came to the Papal See. To some degree at least these interesting teaching methods must have aroused in such men the desire to see them emulated in their own teaching institutions, and therefore must have done much to advance medical education. The fact that these things were done in the Papal Medical School only emphasized the significance of them for ecclesiastics, and made them more ready to bring about their imitation in other teaching centers.
How well the Popes were justified in their estimation of Columbus's genius as an anatomical investigator will be best appreciated from his discovery of the pulmonary circulation, which formed, as Harvey confesses at the beginning of his work on the circulation, the foundation on which Harvey's great discovery naturally arose. It is probable that Columbus would not have come to Rome, in spite of the flattering offers held out to him, only that he was already the personal friend of a number of high ecclesiastics, and even of the Pope who extended the invitation. How well the Popes continued to think of Columbus after his years of work in the Roman Medical School will be well understood from the fact that, when his great work De Re Anatomica was published after his death by his sons, Pope Pius IV. accepted the dedication of it. This was of course not an unusual thing, for many books on other sciences were dedicated to the Popes, and the example thus set was subsequently imitated. Twenty-five years later, Professor Piccolomini dedicated his Anatomical Lectures to Pope Sixtus V. Subsequent anatomical publications of the Papal Medical School were issued under like patronage. The famous edition of Eustachius's anatomical sketches, published under the editorship of Lancisi, is a notable example of this, and went to press mainly at the expense of Pope Clement XI., who realized how valuable they were likely to be for the teaching of anatomy.
These two great discoverers in anatomy, Columbus and Eustachius, were succeeded, as is so often the case in the history of university faculties, by a man more capable of writing about great discoveries than of making them himself. This was Piccolomini, who devoted himself to showing how much the ancients had taught about anatomy, though at the same time he also made clear the place occupied by modern anatomical discoveries. While his name is not attached to any great discovery in the science of anatomy, he is generally acknowledged to have been one of the great teachers of his time and one who was needed just then in order to make people realize how the old and the new in anatomy must be coordinated. Piccolomini's successor in the chair of anatomy at Rome was another original genius and investigator whose name, however, and fame has never been as great among English-speaking people as in Italy, or among the Latin races generally. The fact that he was a rival of Harvey's in the matter of the discovery of the circulation of the blood has always made the Italians exaggerate his position in medical history, while it has undoubtedly made English writers of medical history diminish the importance of his work.
Historians of science consider him worthy to be called the greatest living scientist of his time–the end of the sixteenth century. He was not only a scientific physician, but he was an authority in all the sciences related to medicine, and indeed had profound interests in every branch of physical science. His contemporaries looked up to him as a leader in scientific thought. To anyone who examines the question of the discovery of the circulation of the blood with freedom from bias, there can be no doubt but that the honor for this discovery has been unduly taken away from Caesalpinus in English-speaking countries, to be conferred solely on Harvey. Not that there is any wish to lessen the value of Harvey's magnificent original work, nor make little of his wonderful powers of observation, nor of the marvelous experimental and logical method by which he followed out his thoughts to their legitimate conclusion, but that I would insist on giving honor where honor is due, though most writers in English refuse to give Caesalpinus's claims a proper share of attention.
The Italians have always declared that Caesalpinus was the real discoverer of the circulation, and there is no doubt that his career occurs just at that point in the evolution of the medical sciences, and especially anatomy and physiology in Italy, where this discovery would naturally come. Lest it should be thought, however, that my interest in the Popes and the Papal Medical School has led me to exaggerate the claims of Caesalpinus as a great naturalist and medical scientist, I prefer to quote the description of him given by Professor Michael Foster in his lectures on the History of Physiology, delivered in this country as the Lane Lectures, at the Cooper Medical College in San Francisco, and published by the Cambridge University Press, 1901. Professor Foster was not one to exaggerate the claims of any Italian, and least of all of any Italian who might be supposed to have a claim that would stand against Harvey's. The soupçon of Chauvinism in his treatment of Servetus and Columbus in this regard is indeed rather amusing. He said:–
"Of a very different stamp to Columbus was Andreas Caesalpinus. Born at Arezzo in 1519, he was for many years Professor of Medicine at Pisa, namely, from 1567 to 1592, when he passed to Rome, where he became Professor at the Sapienza University and Physician to Pope Clement VIII., and where at a ripe old age he died in 1603.
"If Columbus lacked general culture, Caesalpinus was drowned in it. Learned in all the learning of the ancients and an enthusiastic Aristotelian, he also early laid hold of all the new learning of the time. Naturalist as well as physician, he taught at Pisa botany as well as medicine, being from 1555 to 1575 Professor of Botany, with charge of the Botanic garden founded there in 1543, the first of its kind–one remaining until the present day."
Professor Foster admits that Caesalpinus had a wonderful power of synthetising knowledge already in hand and anticipating conclusions in science that were to be confirmed subsequently. In his Medical Questions, though the work is written in rambling, discursive vein, he enunciated views which, however he arrived at them, certainly foreshadowed or even anticipated those which were later to be established on a sound basis. Foster quotes a passage in which Caesalpinus made it very clear that he thoroughly understood the mechanism of the circulation and grasped every detail essential to it. After quoting this passage, which it must be confessed is rambling, Foster thus sums up what Caesalpinus has to say with regard to the circulation:–
"He thus appears to have grasped the important truth, hidden, it would seem, from all before him, that the heart, at its systole, discharges its contents into the aorta (and pulmonary artery), and at its diastole receives blood from the vena cava (and pulmonary vein)."
"Again, in his Medical Questions he seems to have grasped the facts of the flow from the arteries to the veins, and of the flow along the veins to the heart."
That there was no change of Papal policy in the next century can be gathered from an interesting phase of Papal interest in science which, though not directly concerned with medicine, eventually resulted in important theoretic advances in medical science. This was the encouragement of Father Kircher's work at Rome. Father Kircher was the Jesuit who made the first scientific museum. As the result of his general interest in things scientific he wrote a little book on the pest. In this book he stated in very clear terms the modern doctrine of the origin of disease from little living things, which he called corpuscles. Because of this Tyndall attributes to Father Kircher the first realization of the role that bacteria play in disease. Even more wonderful than this, however, was Father Kircher's anticipation of modern ideas with regard to the conveyance of disease. He insisted that contagious diseases, as a rule, were not carried, as had been thought, by the air, but were conveyed from one person to another, either directly, or by the intermediation of some living thing. He considered that cats and dogs were surely active in conveying diseases, and he even reached the conclusion that insects were also important in this matter. His expressions with regard to this are not of the indefinite character which one often encounters in the supposed anticipation of important principles in medicine, but are very precise and definite. Father Kircher is quoted by Dr. Howard Kelly, of Baltimore, in his life of Major Walter Reed, whose work in showing that yellow fever is transmitted by mosquitoes is well known, as saying in one place, "Flies carry the plague," and in another place, "There can be no doubt that flies feed on the internal secretions of the diseased dying, then flying away they deposit their excretions on the food in neighboring dwellings, and persons who eat it are thus infected." It is interesting to find that the Professor of the Practice of Medicine in the Papal University at Rome when this book was published, far from resenting, as many professors of medicine might, the excursion of an outsider into his science, said Father Kircher's book "not only contains an excellent resume of all that is known about the pest or plague, but also many valuable hints and suggestions on the regional spread of the disease which had never before been made." He did not hesitate to add that it was marvelous for a man, not educated as a physician, to have reached such surprising conclusions, which seemed worthy of general acceptance. All this, it may be said in passing, was within a few years after the trial of Galileo. In this next century the Popes continued their special efforts to secure the greatest teachers of anatomy and physiology for their Roman medical school. One of the results was the appointment of Malpighi, whose name has deservedly become attached to more structures in the human body because of tissues which he first studied in detail, than any other man in the history of medicine. Malpighi represents the beginning of most of the comparative biological sciences, and his original observations upon plants, upon the lower animals, on fishes and then on the anatomical structure of man and the higher animals, stamp him as an investigating genius of the highest order. He was the personal friend of Innocent XI., who wished to have him near him at Rome as his own medical adviser, and besides desired the prestige of his fame and the stimulating example of his investigating spirit for the students of the medical school of the Sapienza. The closing years of Malpighi's life were rendered happier, and his wonderful researches were as well rewarded as such work can be, by the estimation in which he was held at Rome.
Malpighi was succeeded as Papal Physician and Professor in Rome by Tozzi, who is distinguished in the history of medicine for his commentaries on the ancients rather than for original observation, but who was looked upon in his time as one of the most prominent physicians in Italy. Tozzi had been the Professor of Medicine and Mathematics at the University of Naples, where he became famous. From here he received a flattering invitation to the chair of physic at Padua. In order that he might not desert Naples, his salary was raised and he was given the post of Protomedicus or Chief Physician to the Court. It was after this that the death of Malpighi left an important chair vacant in Rome, and there being no one apparently more worthy than this man for whom other important universities were contending, he was offered the chair on such excellent conditions that he accepted it. It is another case of the Popes being not only willing and even anxious, but also able because of their position, to secure the best talent available for their medical school at the Roman University.
Undoubtedly one of the greatest members of the faculty that the Papal Medical School ever had is Lancisi, one of the supreme medical teachers of history, who is usually considered one of the founders of modern clinical medicine. When at the beginning of the eighteenth century Boerhaave attracted the attention of the world by his bedside teaching of medicine at Leyden, there were two occupants of thrones in Europe who proved to have particular interest in this new departure. They were perhaps the last two who might ordinarily be expected to have much use for such improvements in medical education. One of them was the Empress Maria Theresa, of Austria, whose patronage of Boerhaave 's pupil, Van Swieten, secured the establishment of that system of clinical teaching which has since made the Vienna Medical School famous. The other was the Pope. With his approbation Lancisi established clinical teaching at Rome, and thus did much to maintain at Rome a great center of medical progress during the eighteenth century.
Lancisi was graduated at the Sapienza, the Roman University, at the early age of eighteen. When only twenty-two he became assistant physician at the Santo Spirito Hospital and began to show the first hint of the brilliant genius he was to display later in life.
Some ten years later, as the result of a competitive examination which still further demonstrated his talents, he was chosen Professor of Anatomy in his Alma Mater, the Sapienza. He was only thirty-three at the time, and the fact that he should be chosen shows that the Papal University was ready to take advantage of talent wherever it found it and did not allow itself to be won only by notoriety at a distance. The excellence of the choice was demonstrated before long by Lancisi's brilliant career as a teacher and an original investigator. Some of the most distinguished medical men from all over the world came to listen to his lectures (according to Hirsch's Biographical Lexicon of the Most Prominent Physicians of All Times and Peoples), and even Malpighi and Tozzi, the Papal physicians during the time, were among his auditors. [Footnote 29]
[Footnote 29: Most of these details are taken from Hirsch's Biographisches Lexicon der hervorragenden Aertzte aller Zeiten und Völker. Wien und Leipzig, 1886.]
After the departure of Tozzi from Rome Lancisi became the Papal physician. He continued to be the medical adviser of Popes Innocent XI. and XII. and of Clement XI. until his death in 1720. It was under Clement that he had the new clinic built, in which teaching after the manner of Boerhaave was to be established. At his death Lancisi left his fortune and his library to Santo Spirito Hospital, on condition that a new portion of the hospital should be erected for women. There is no doubt that he belongs among the most distinguished of contributors to medical science, and Hirsch declares that anatomy, practical medicine, and hygiene are indebted to him for notable achievements. His books are still classics. The one on Sudden Death worked a revolution in the medical diseases of the brain and heart. His work De Motu Cordis et Aneurysmatibus has been pronounced epoch-making, and his suggestion of percussion over the sternum in order to determine the presence of an aneurysm, made him almost an anticipator of Auenbrugger and prompted Morgagni's famous book De Sedibus et Causis Morborum, which appeared after his death. Lancisi's work on Aneurysms was not published until after his death.
Two others of his books deserve mention because they show how broad were the interests of the man in many phases of progress in medicine. Their titles are Diseases and Infections of Domestic Animals and The Climate of Rome.
The next great name in Italian medicine is that of Morgagni. He was not a regular Papal physician, nor a member of the faculty of the Papal Medical School, but he was often consulted, as we told in the chapter on Papal Physicians, both as to the health of the Popes and the methods of teaching at the Roman Medical School. His life brings us down almost to the nineteenth century, and the cordial relations of the Popes to him, far from being an exception in the history of medicine, are only typical of the attitude of the Roman Pontiffs to medical and all other scientists from the dawn of the history of science in modern times.
While the Papal Medical School at Rome, attached to the university of the city and directly under the control of the Papal Curia, more especially deserves the name thus given it, it must not be forgotten that there was in the Papal States a series of medical schools in various cities. One of these, at Perugia, founded by a bull of Pope John XXII., has come under consideration in the chapter on A Papal Patron of Medical Education. Another medical school, that of Ferrara, which also was in the Papal States, had considerable prestige. Some distinguished professors taught there before going to Padua or Bologna. At the beginning of the sixteenth century, Bologna, after having been during the preceding three centuries under the domination of one powerful family or another, from the Pepoli to the Bentivogli, and then to the Visconti and back again to the Bentivogli, was incorporated in the Papal States under Pope Julius II. At this time the Medical School of Bologna was at the height of its reputation and was one of the two greatest medical schools in Italy. Padua was its only rival. Shortly after this Rome became a serious competitor in medical education. Practically, then, this was a second Papal medical school, almost as directly under the control of the Popes as the Roman Medical School. Far from there being any diminution in the glory or the efficiency of the Bolognese Medical School, its reputation even became enhanced after the city came under the control of the Popes.
This is all the more surprising because, as we have shown, just about this time the Popes began the work of making their Medical School at Rome the most important center for medical education, especially in the scientific phases of medicine–anatomy, physiology, and comparative anatomy–that there was at that time in the world. In spite of this rivalry, however, nothing was done directly to hurt the prestige of the school of Bologna, and indeed the rivalry seems to have been more of an encouraging competition than in any sense a destructive struggle for existence. When the Popes took possession of Bologna, Alexander Achillini was professor of anatomy and medicine in the Bolognese school, and his discoveries and methods of investigation attracted the attention of students from all over the world. His assistant for many years and his successor in the post was Berengar of Carpi, of whom we have already said much in the chapter Anatomy Down to the Renaissance. For some time Vesalius lectured on medicine and anatomy at Bologna, and one of Berengar's most distinguished successors in the sixteenth century was Aranzi, who occupied the post of anatomical professor for thirty-two years and who corrected a number of errors in anatomical detail that had been made by Vesalius and others of the preceding generation. He confirmed Columbus's discoveries at Rome with regard to the course which the blood follows in passing from the right to the left side of the heart, and made many important additions to the knowledge of the anatomical relations of the cavities of the heart, the valves, and the great blood vessels. There are a number of important structures in the brain which owe their names to him, and his descriptions of them are better, according to Prof. Turner, than those of other anatomists for a century after his time.
The tradition of great teachers thus carried on during the first century after the absorption of Bologna into the Papal States, continued uninterruptedly in the next century, when we find on the list of professors at Bologna such names as those of Malpighi, the greatest mind in the medical sciences of the seventeenth century, and his colleague Fracassati, who, though over-shrouded by Malpighi, still claims a prominent place in the history of medicine. Bologna has a special feature of medical development to its credit which, because of its importance for science in general as well as for medicine, deserves to be mentioned here. During the century after the Popes became the rulers of the city scientific societies were founded here, and as the professors and students of the medical school were also the most interested in science in general, the membership of these societies was largely made up of individuals connected with the medical school. A special society for the cultivation of anatomical knowledge, the first of its kind ever founded, was established in Bologna scarcely more than a century after the city came under the Papal dominion. It was called the Coro Anatomico, or anatomical choir, and had at first only nine members. Among these, however, were such distinguished men as Malpighi, Fracassati, Capponi, and Massari, to the last of whom the initiative of the foundation of the society is said to have been due. Bologna was noted during the sixteenth and seventeenth centuries for the number of foreign students of medicine who were attracted to its hospitable medical school and who carried the tradition of science for its own sake, so characteristic of this Papal Medical School, to all parts of the world.
After this consideration of the relation of the Popes to medical science during many centuries when medicine practically included all the physical sciences, it may seem utterly inexplicable to any fair-minded person that the tradition of the opposition of the Popes to science and scientific educational development should have apparently become a commonplace in history. This will not be a surprise, however, to those who know how perversive and influential has been the Protestant tradition which from the beginning of the sixteenth century has devoted itself to blackening the reputation of the Church, the Popes, and Catholic ecclesiastics generally. Nowhere is this more true than in history as written for English-speaking people. Those who left the old Church and their immediate descendants, justified their withdrawal to themselves as well as others, by taking every possible excuse and inventing every possible pretext, to show how unworthy of their continued allegiance the old Church had been. The point of view thus assumed was taken quite seriously by succeeding generations, until at length a whole body of historical traditions, utterly unfounded in fact, accumulated, especially in England, where it must be remembered that for several centuries Catholics were not in a position to impugn and eradicate it. This unfortunate state of affairs, and not real opposition on the part of the Popes to science, is the source of the tradition with regard to the supposed opposition between the Church and science.
