With this list before him, the reader will have all the material necessary to understand the declaration that there is no series of men whose names are connected together by any bond in the history of medicine, even as members of the faculty of our oldest medical schools, that represent so much achievement and original investigation in medical matters as the Papal Physicians. With these men beside them as advisers and very often as intimate friends, it would have been quite impossible for the Popes to have been deliberate opponents of scientific progress. We all know that by a curious irony of fate physicians are sometimes found ranged against the line of advance in medical science, but this is inevitable with human frailty and the incidents of opposition have not done nearly so much harm as their conservative refusal to listen to enthusiastic discoverers, whose discovery was of no significance, has done of {468} good. No medical society in the world has an unblemished record of constant readiness to accept genuine new discoveries and all of them have sometime or other been in opposition to what proved eventually to be significant scientific progress. There are no striking incidents in the lives of the Papal Physicians in this regard though their admiration for Aristotle, Hippocrates and Galen sometimes kept them over conservative. As a rule, however, they were ready to welcome every new step in medical advance that was made.

We all know how much a man's physician usually means in influencing him with regard to the att.i.tude that he shall a.s.sume towards scientific advances generally and particularly announced progress in the biological sciences. The Popes could scarcely have had better advisers in this matter than the men who were actually chosen as Papal Physicians. They came from every part of Italy and sometimes even from other countries. A library consisting of their works alone would contain an extremely valuable collection of books ill.u.s.trating nearly every phase of advance in medicine.

APPENDIX VI.

ASTRONOMY AND THE CHURCH.

_Some Roman Astronomers_.

A formal list of Papal Astronomers in any way comparable to that of the Papal Physicians cannot be given. Astronomy is not so compelling in its interests as medicine and while man's first serious scientific interest is his body, and the first modern university, that of Salerno, was founded around a medical school, the development of astronomy as a science was practically delayed until the Renaissance.

Though a formal list of Papal Astronomers is not available, there is, however, a long series of names of workers in astronomy at Rome, some of whom occupied positions in the Papal capital actually called by that name, with many others who merited it for the work they did with Papal aid and encouragement. A large number of astronomical investigators conducted their researches under the patronage of the Popes, often dedicated their books, with permission, to them, were frequently supported by Papal revenues and had their observatories supplied by the Papal government, or else they were in intimate relations with the Papacy and received every stimulus for their researches.

For special purposes, as the correction of the calendar, distinguished astronomers were summoned from long distances to Rome. At the Sapienza Papal University and later at the Roman College directly under the control of the Jesuits, but with the entire approval and constant effective good-will of the Popes, men of great distinction in astronomy and mathematics have frequently been professors. Some of the very greatest contributions to the science of astronomy have been issued not only with dedications to the Popes, as I have said, but not infrequently have been printed at the expense of the Holy See.

In the chapter on Papal Physicians I have suggested that no list of men connected by any bond in the history of medicine are so distinguished as the roll of the Papal Physicians. The faculty of no medical school, for instance, no matter how long it may be able to trace its history, contains so many distinguished names. This same thing might well be said of the list of men who have done distinguished work in astronomy whose names are in some way {470} connected with the Papacy and whose relations to the Popes make it very clear that far from a determined course of opposition there was, on the contrary, a definite policy of encouragement and patronage for astronomical workers and that this greatly helped the diffusion of valuable scientific information with regard to the heavens and made the ecclesiastics of the world particularly interested in these important advances in human knowledge. In this appendix, then, as a complement to the appendix on the Papal Physicians, I have brought together some of the names and the achievements of astronomers who worked at Rome or were in some way connected with the Popes. I know that it is incomplete, but even as it stands it is a strong confirmation of that principle so surprising to many presumably well-informed people that the Popes were, as far as conditions permitted, always the patrons, not the persecutors, of scientists in all departments of the purely physical as well as biological, theoretic and applied sciences.

It is sometimes a.s.sumed in the modern time, and it used to be the custom a generation ago for nearly everyone in English-speaking countries to a.s.sume, that because we knew very little about science in the medieval period it must be because there was very little to know.

We have learned the fallacy of that supposition to our cost, by the republication of the great text-books of medicine and surgery of the medieval period and by the deeper study of such great scholars as Roger Bacon, Albertus Magnus and St. Thomas Aquinas. Even the scanty records that we have show us the Popes following the same sort of policy with regard to education and science as at the present time.

Men who collected scientific information for academic or popular diffusion, as Isidore of Seville, Albertus Magnus, Thomas of Aquin, were not infrequently raised to ecclesiastical dignities during life and placed among the saints after death. Occasionally a distinguished scientist like Gerbert, who became Pope Sylvester II, or Petrus Hispa.n.u.s the well-known physician, who became Pope John XXI, were even made Popes. It is easy to understand that their att.i.tude as Supreme Pontiffs towards science would be not only not one of opposition but of sympathy and helpful patronage.

While as I have said astronomy as a formal science practically did not develop until the Renaissance, there were a series of important discussions of the relations of the earth to the other heavenly bodies and of the size and shape of the earth itself among the professors of the medieval universities, and the perfect freedom with which these discussions were carried on shows how unshackled {471} was human thought. Albertus Magnus discussed the antipodes, dismissed the notion that if there were men on the other side of the earth they would surely fall off by the thoroughly Socratic remark that we ourselves were on the other side from them yet did not fall off, and understood and taught very definitely the rotundity of the earth and other doctrines that are usually supposed to be much more recent, and that are often said to have brought their holders into ecclesiastical odium. Far from this, Albert was always in high favor and was made a bishop and canonized as a saint after his death.

Roger Bacon studied light, declared that it moved with a definite velocity and gathered and made good use in his teaching of an immense amount of information in the departments of knowledge that we now call astronomy and geography. Humboldt declared that it was a pa.s.sage from Roger Bacon which more than anything else, even the Toscanelli letters, roused Columbus to his life purpose of sailing westwards.

Roger Bacon's books, the one with the paragraph now famous because of its connection with Columbus among the number, were issued at the request of the Pope and it seems very probable that we would have had no idea of his marvellous antic.i.p.ation of many modern scientific truths only for the definitely expressed wish of the Pope to know the English Franciscan's thought. We have just celebrated the seventh centenary of Roger Bacon's birth, and this has brought home to us how much of a loss to the history of human culture would have been the missing of Bacon's works. Bacon's difficulties in life were with his Order and were personal matters not directly connected with his science.

With the beginning of the Renaissance the stimulating effect of the study of Greek science on the men of the fifteenth century was exerted and one of those who was most deeply touched by the Greek spirit was Cardinal Nicholas of Cusa, or Cusa.n.u.s, as he is called from the Latin name of his birthplace. He wrote a series of books touching many matters in science and treating various phases of mathematics. He dwelt particularly on certain problems relating to geography and astronomy. I have summed up his scientific career in a chapter of ”Old Time Makers of Medicine” (N. Y., 1911). He taught the rotundity of the earth and that the earth was the same sort of a body as the other stars in the heavens, that it was not and could not be the centre of the universe and that it had a movement of its own. Far from such revolutionary teaching leading to his persecution or bringing him under the suspicion {472} of the ecclesiastical authorities he was, on the contrary, looked up to for his scholars.h.i.+p, received successive ecclesiastical preferments, became Bishop of Brixen and then Papal Legate to Germany for the reform of abuses, and finally a Cardinal. He did much to encourage interest in mathematical, geographical and astronomical science, provided opportunities for students, encouraged Puerbach and Regiomonta.n.u.s in their significant pioneer work in mathematics and astronomy, and generally showed himself the enlightened patron of every movement related to the physical sciences, and all the workers with the experimental method.

The first epoch-making astronomer who was brought into intimate relations with the Pope of whom we have definite knowledge was Regiomonta.n.u.s. He is deservedly known as the Father of Modern Astronomy for his initiation of series of calculations and publications with regard to the heavens and his establishment at Nuremburg of a regular observatory. He was summoned to Rome to direct the calculations for the correction of the calendar, but unfortunately died there at the early age of forty. His invitation to Rome for this purpose came within the same decade when, if we were to trust certain modern historians of the relations of the Popes to science, Pope Calixtus III issued his supposed bull against Halley's comet. The bull has never been found. The att.i.tude of the Popes towards science is much better ill.u.s.trated by the invitation to Regiomonta.n.u.s and the encouragement of astronomical research thus afforded than by the fict.i.tious bull against the comet. The supposed bull has, however, played a large role in convincing a number of people of Church opposition to science, some of them being professors of science who knew nothing about the almost simultaneous appointment of Regiomonta.n.u.s as Papal Astronomer.

Toscanelli, over the question of whose influence on Columbus an as yet unsettled controversy is waged, was a lifelong friend of Nicholas of Cusa, they had been schoolmates at College and undoubtedly the great cardinal doctor of laws or of decrees as they said at that time, owed much of his progressive advanced views on scientific subjects to his Florentine friend ”the doctor of physic, Paul Toscanelli.” Cusa.n.u.s at the height of his fame dedicated his book on Geometrical Transformations ”to Paul the Florentine physician.” Regiomonta.n.u.s, as well as Cusa, often sought Toscanelli's opinion on abstruse questions of mathematics and quoted him with confidence. The intimate relations of Cusa.n.u.s and Regiomonta.n.u.s with the Popes of the middle of the fifteenth century are very well known. Toscanelli's services to astronomy are only {473} less famous than those to cosmography. A series of his careful and painstaking observations and calculations of the orbits of the comets of 1433, 1449-50, of Halley's comet of 1456 and of the comets of 1457 and 1472 are preserved in ma.n.u.script. They demonstrate his profound and successful interest in astronomical subject and it is easy to see that they must have cost him, as indeed he tells in his letters, many a night's watching of the stars. The relations between the ecclesiastical authorities and Toscanelli are very well ill.u.s.trated by that well-known monument to his astronomical skill which still interests visitors so much in the Cathedral of Santa Maria del Fiore at Florence. This is the gnomon arranged in the dome of the Cathedral by the shadow of which it is said that he could determine midday to within half a second. The use of the Cathedral for this purpose is interesting testimony to the cordial relations of science and religion at this time. It may be said in pa.s.sing that Toscanelli's gnomon was later improved by Cardinal Ximenes of Spain, showing that these cordial ecclesiastical relations with science were not confined to Italy.

While Toscanelli was making his observations Antoninus of Florence was for some thirteen years the Archbishop of the city and was one of the learned members of the Dominican Order at this time, who had made his novitiate among the Dominicans with Fra Angelico and Fra Bartholomeo the great Renaissance painters. Antoninus was greatly influenced evidently by his a.s.sociations with Toscanelli and formed one of a group of men containing the Florentine physician astronomer, Cardinal Cusa.n.u.s and Regiomonta.n.u.s, himself afterwards a bishop, who were on terms of intimate relations.h.i.+p at least in scholarly matters at this period. Archbishop Antoninus, who is the author of a _Summa Theologica Moralis_ of which no less than fifteen editions were printed after his death, wrote also a series of histories in which he shows this influence by insisting that comets are celestial bodies like the others in the heavens and had no effect on the physical or moral conditions of the world and, quite contrary to popular beliefs, were not responsible for war or pestilence nor prophetic of evil to mankind. There had been a number of brilliant comets in the heavens about this time and there was consequently a widespread interest in them and much popular superst.i.tion with regard to them. Antoninus was on terms of familiar intimacy with Pope Eugene IV, who insisted on his becoming Archbishop of Florence, though Antoninus would have preferred to have remained a simple Dominican and keep his leisure for his scholarly work. When the Pope felt his end {474} approaching he called Antoninus to Rome to administer the last rites of the Church to him and be by his side during his last hours. Antoninus was frequently consulted by Pope Eugene's successors, Nicholas V and Pius II, both of whom were among the scholarly patrons of learning and art at this time. Some fifty years after his death Antoninus was canonized by Pope Hadrian VI, the scholarly Pope from Utrecht in Holland. His whole career then shows clearly the relations of the ecclesiastics and particularly the Popes of the time to science in a most favorable light.

The relations.h.i.+p with the rising science of the Renaissance period thus initiated was continued during the following century. At the end of the fifteenth century Copernicus studied for ten years in Italy and felt so thoroughly the interest of Italians in advances in science as well as scholars.h.i.+p that when some years later he came to formulate his great new hypothesis of the heavens, he sent an abstract of his theory to some of the Roman teachers with whom he had become intimate during his stay and it was taught publicly in the city to crowded audiences. This may well seem surprising to many whose only knowledge of the relations of the Popes to astronomy is the Galileo incident, but it must not be forgotten that Copernicus' great work in which he elaborated his theory, was dedicated, with permission, to the Pope, and not only received no censure until Galileo's time, nearly a century later, but was welcomed as a great contribution to science and thought. It was looked upon as a theory, to be discussed as any other.

When Galileo, at the end of the first quarter of the seventeenth century, insisted on teaching it as absolute science, it must not be forgotten that there were no astronomers in Europe who looked upon Copernicanism as an accepted scientific doctrine. Even the reasons advanced by Galileo for its acceptance have all since been rejected.

Owing to the discussions of it far and wide in the time of Galileo, certain expressions in Copernicus' great work were required by the Church authorities to be corrected so that his explanation of the heavens should be presented as the theory that it was and not as an absolute doctrine of science.
