Chapter 5

It has often been the subject of misunderstanding as to why medicine should have developed among the Latin Christian nations so much more slowly than among the Arabs during the early Middle Ages. Anyone who knows the conditions in which Christianity came into existence in Italy will not be surprised at that. The Arabs in the East were in contact with Greek thought, and that is eminently prolific and inspiring. At the most, the Christians in Italy got their inspiration at second hand through the Romans. The Romans themselves, in spite of intimate contact with Greek physicians, never made any important contributions to medical science, nor to science of any kind. Their successors, the Christians of Rome and Italy, then could scarcely be expected to do better, hampered especially, as they were, by the trying social conditions created by the invasion of the barbarians from the North. Whenever the Christians were in contact with Greek thought and Greek medicine, above all, as at Alexandria, or in certain of the cities of the near East, we have distinguished contributions from them.

ARABIAN CHRISTIAN PHYSICIANS

That this is not a partial view suggested by the desire to make out a better case for Christianity in its relation to science will be very well understood, besides, from the fact that a number of the original physicians of Arab stock who attracted attention during the first period of Arabian medicine, that is, during the eighth and ninth centuries, were Christians. There are a series of physicians belonging to the Christian family Bachtischua, a name which is derived from Bocht Jesu, that is, servant of Jesus, who, from the middle of the eighth to the middle of the eleventh century, acquired great fame. The first of them, George (Dschordschis), after acquiring fame elsewhere, was called to Bagdad by the Caliph El-Mansur, where, because of his medical skill, he reached the highest honors. His son became the body-physician of Harun al-Raschid. In the third generation Gabriel (Dschibril) acquired fame and did much, as had his father and grandfather, for the medicine of the time, by translations of the Greek physicians into Arabian.

These men may well be said to have introduced Greek medicine to the Mohammedans. It was their teaching that aroused Moslem scholars from the apathy that had characterized the attitude of the Arabian people toward science at the beginning of Mohammedanism. As time went on, other great Christian medical teachers distinguished themselves among the Arabs. Of these the most prominent was Messui the elder, who is also known as Janus Damascenus. Both he and his father practised medicine with great success in Bagdad, and his son became the body-physician to Harun al-Raschid either after or in conjunction with Gabriel Bachtischua. Like his colleague or predecessor in official position, he, too, made translations from the Greek into Arabic. Another distinguished Arabian Christian physician was Serapion the elder. He was born in Damascus, and flourished about the middle of the ninth century. He wrote a book on medicine called the "Aggregator," or "Breviarium," or "Practica Medicinae," which appeared in many printed editions within the century after the invention of printing. During the ninth century, also, we have an account of Honein Ben Ischak, who is known in the West as Johannitius. After travelling much, especially in Greece and Persia, he settled in Bagdad, and, under the patronage of the Caliph Mamum, made many translations. He translated most of the old Greek medical writers, and also certain of the Greek philosophic and mathematical works. The accuracy of his translations became a proverb. His compendium of Galen was the text-book of medicine in the West for many centuries. It was known as the "Isagoge in Artem Parvam Galeni." His son, Ishac Ben Honein, and his nephew, Hobeisch, were also famous as medical practitioners and translators.

Still another of these Arabian Christians, who acquired a reputation as writers in medicine, was Alkindus. He wrote with regard to nearly everything, however, and so came to be called the philosopher. He is said altogether to have written and translated about two hundred works, of which twenty-two treat of medicine. He was a contemporary of Honein Ben Ischak in the ninth century. Another of the great ninth-century Christian physicians and translators from the Greek was Kostaben Luka. He was of Greek origin, but lived in Armenia and made translations from Greek into Arabic. Nearly all of these men took not alone medical science, but the whole round of physical science, for their special subject. A typical example in the ninth century was Abuhassan Ben Korra, many of whose family during succeeding generations attracted attention as scholars. He became the astronomer and physician of the Caliph Motadhid. His translations in medical literature were mainly excerpts from Hippocrates and Galen meant for popular use. These Christian translators, thoroughly scientific as far as their times permitted them to be, were wonderfully industrious in their work as translators, great teachers in every sense of the word, and they are the men who formed the traditions on which the greater Arabian physicians from Rhazes onward were educated.

It would be easy to think that these men, occupied so much with translations, and intent on the re-introduction of Greek medicine, might have depended very little on their own observations, and been very impractical. All that is needed to counteract any such false impression, however, is to know something definite about their books. Gurlt, in his "History of Surgery," has some quotations from Serapion the elder, who is often quoted by Rhazes. In the treatment of hemorrhoids Serapion advises ligature and insists that they must be tied with a silk thread or with some other strong thread, and then relief will come. He says some people burn them _medicinis acutis_ (touching with acids, as some do even yet), and some incise them with a knife. He prefers the ligature, however. He calmly discusses the removal of stones from the kidney by incision of the pelvis of the kidney through an opening in the loin. He considers the operation very dangerous, however, but seems to think the removal of a stone from the bladder a rather simple procedure. His description of the technique of the use of a catheter and of a stylet with it, and apparently also of a guide for it in difficult cases, is extremely interesting. He suggests the opening of the bladder in the median line, midway between the scrotum and the anus, and the placing of a canula therein, so as to permit drainage until healing occurs.

Even this brief review of the careers and the writings of the physicians of early Christian times shows how well the tradition of old Greek medicine was being carried on. There was much to hamper the cultivation of science in the disturbances of the time, the gradual breaking up of the Roman Empire, and the replacement of the peoples of southern Europe by the northern nations, who had come in, yet in spite of all this, medical tradition was well preserved. The most prominent of the conservators were themselves men whose opinions on problems of practical medicine were often of value, and whose powers of observation frequently cannot but be admired. There is absolutely no trace of anything like opposition to the development of medical science or medical practice, but, on the contrary, everywhere among political and ecclesiastical authorities, we find encouragement and patronage. The very fact that, in the storm and stress of the succeeding centuries, manuscript copies of the writings of the physicians of this time were preserved for us in spite of the many vicissitudes to which they were subjected from fire, and war, and accidents of various kinds for hundreds of years, until the coming of printing, shows in what estimation they were held. During this time they owed their preservation to churchmen, for the libraries and the copying-rooms were all under ecclesiastical control.

GREAT JEWISH PHYSICIANS[3]

Any account of Old-Time Makers of Medicine without a chapter on the Jewish Physicians would indeed be incomplete. They are among the most important factors in medieval medicine, representing one of the most significant elements of medical progress. In spite of the disadvantages under which their race labored because of the popular feeling against them on the part of the Christians in the earlier centuries and of the Mohammedans later, men of genius from the race succeeded in making their influence felt not only on their own times, but accomplished so much in making and writing medicine as to influence many subsequent generations. Living the segregated life that as a rule they had to, from the earliest times (the Ghettos have only disappeared in the nineteenth century), it would seem almost impossible for them to have done great intellectual work. It is one of the very common illusions, however, that great intellectual work is accomplished mainly in the midst of comfortable circumstances and as the result of encouraging conditions. Most of our great makers of medicine at all times, and never more so than during the past century, have been the sons of the poor, who have had to earn their own living, as a rule, before they reached manhood, and who have always had the spur of that necessity which has been so well called the mother of invention. Their hard living conditions probably rather favored than hampered their intellectual accomplishments.

It is not unlikely that the difficult personal circumstances in which the Jews were placed had a good deal to do at all times with stimulating their ambitions and making them accomplish all that was in them. Certain it is that at all times we find a wonderful power in the people to rise above their conditions. With them, however, as with other peoples, luxury, riches, comfort, bring a surfeit to initiative and the race does not accomplish so much. At various times in the early Middle Ages, particularly, we find Jewish physicians doing great work and obtaining precious acknowledgment for it in spite of the most discouraging conditions. Later it is not unusual to find that there has been a degeneration into mere money-making as the result of opportunity and consequent ease and luxury. At a number of times, however, both in Christian and in Mohammedan countries, great Jewish physicians arose whose names have come to us and with whom every student of medicine who wants to know something about the details of the course of medical history must be familiar. There are men among them who must be considered among the great lights of medicine, significant makers always of the art and also in nearly all cases of the science of medicine.

A little consideration of the history of the Jewish people and their great documents eliminates any surprise there may be with regard to their interest in medicine and successful pursuit of it during the Middle Ages. The two great collections of Hebrew documents, the Old Testament and the Talmud, contain an immense amount of material with reference to medical problems of many kinds. Both of these works are especially interesting because of what they have to say of preventive medicine and with regard to the recognition of disease. Our prophylaxis and diagnosis are important scientific departments of medicine dependent on observation rather than on theory. While therapeutics has wandered into all sorts of absurdities, the advances made in prophylaxis and in diagnosis have always remained valuable, and though at times they have been forgotten, re-discovery only emphasizes the value of preceding work. It is because of what they contain with regard to these two important medical subjects that the Old Testament and the Talmud are landmarks in the history of medicine as well as of religion.

Baas, in his "Outlines of the History of Medicine," says: "It corresponds to the reality in both the actual and chronological point of view to consider the books of Moses as the foundation of sanitary science. The more we have learned about sanitation in the prophylaxis of disease and in the prevention of contagion in the modern time, the more have we come to appreciate highly the teachings of these old times on such subjects. Moses made a masterly exposition of the knowledge necessary to prevent contagious disease when he laid down the rules with regard to leprosy, first as to careful differentiation, then as to isolation, and finally as to disinfection after it had come to be sure that cure had taken place. The great lawgiver could insist emphatically that the keeping of the laws of God not only was good for a man's soul but also for his body."

With this tradition familiarly known and deeply studied by the mass of the Hebrew people, it is no surprise to find that when the next great Hebrew development of religious writing came in the Talmud during the earlier Middle Ages, that also contains much with regard to medicine, not a little of which is so close to absolute truth as never to be out of date. Friedenwald, in his "Jewish Physicians and the Contributions of the Jews to the Science of Medicine," a lecture delivered before the Gratz College of Philadelphia fifteen years ago, summed up from Baas' "History of Medicine" the instructions in the Talmud with regard to health and disease. The summary represents so much more of genuine knowledge of medicine and surgery than might be expected at the early period at which it was written, during the first and second century of our era, that it seems well to quote it at some length.

"Fever was regarded as nature's effort to expel morbific matter and restore health; which is a much safer interpretation of fever, from a practical point of view, than most of the theories bearing on this point that have been taught up to a very recent period. They attributed the halting in the hind legs of a lamb to a callosity formed around the spinal cord. This was a great advance in the knowledge of the physiology of the nervous system. An emetic was recommended as the best remedy for nausea. In many cases no better remedy is known to-day. They taught that a sudden change in diet was injurious, even if the quality brought by the change was better. That milk fresh from the udder was the best. The Talmud describes jaundice and correctly ascribes it to the retention of bile, and speaks of dropsy as due to the retention of urine. It teaches that atrophy or rupture of the kidneys is fatal. Induration of the lungs (tuberculosis) was regarded as incurable. Suppuration of the spinal cord had an early, grave meaning. Rabies was known. The following is a description given of the dog's condition: 'His mouth is open, the saliva issues from his mouth; his ears drop; his tail hangs between his legs; he runs sideways, and the dogs bark at him; others say that he barks himself, and that his voice is very weak. No man has appeared who could say that he has seen a man live who was bitten by a mad dog.' The description is good, and this prognosis as to hydrophobia in man has remained unaltered till in our day when Pasteur published his startling revelation. The anatomical knowledge of the Talmudists was derived chiefly from dissection of the animals. As a very remarkable piece of practical anatomy for its very early date is the procuring of the skeleton from the body of a prostitute by the process of boiling, by Rabbi Ishmael, a physician, at the close of the first century. He gives the number of bones as 252 instead of 232. The Talmudists knew the origin of the spinal cord at the foramen magnum and its form of termination; they described the oesophagus as being composed of two coats; they speak of the pleura as the double covering of the lungs; and mention the special coat of fat about the kidneys. They had made progress in obstetrics; described monstrosities and congenital deformities; practised version, evisceration, and Caesarian section upon the dead and upon the living mother. A.H. Israels has clearly shown in his 'Dissertatio Historico-Medica Inauguralis' that Caesarian section, according to the Talmud, was performed among the Jews with safety to mother and child. The surgery of the Talmud includes a knowledge of dislocation of the thigh bone, contusions of the skull, perforation of the lungs, oesophagus, stomach, small intestines, and gall bladder; wounds of the spinal cord, windpipe, of fractures of the ribs, etc. They described imperforate anus and how it was to be relieved by operation. Chanina Ben Chania inserted natural and wooden teeth as early as the second century, C.E."

There is a famous summing up of the possibilities of life and happiness in the Talmud that has been often quoted--its possible wanting in gallantry being set down to the times in which it was written. "Life is compatible with any disease, provided the bowels remain open; any kind of pain, provided the heart remain unaffected; any kind of uneasiness, provided the head is not attacked; all manner of evils, except it be a bad woman."

There are many other interesting suggestions in the Talmud. Sometimes they have come to be generally accepted in the modern time, sometimes they are only curious notions that have not, however, lost all their interest. The crucial incision for carbuncle is a typical example of the first class and the suggestion of the removal of superfluous fat from within the abdomen or in the abdominal wall itself by operation is another. That they had some idea of the danger of sepsis may be gathered from the fact that they suspected iron surgical instruments and advised the use of others of less enduring character.

The Talmud itself was indeed a sort of encyclopedia in which was gathered knowledge of all kinds from many sources. It was not particularly a book of medicine, though it contains so many medical ideas. In many parts of it the authors' regard for science is emphatically expressed. Landau, in his "History of Jewish Physicians," closes his account of the Talmud with this paragraph:

"I conclude this brief review of Talmudic medicine with some reference to how high the worth of science was valued in this much misunderstood work. In one place we have the expression 'occupation with science means more than sacrifice.' In another 'science is more than priesthood and kingly dignity.'"[4]

After all this of national tradition in medicine before and after Christ, it is only what we might quite naturally expect to find, that there is scarcely a century of the Middle Ages which does not contain at least one great Jewish physician and sometimes there are more. Many of these men made distinct contributions to medical science and their names have been held in high estimation ever since. Perhaps I should say that they were held in high estimation until that neglect of historical studies which characterized the eighteenth century developed, and that there has been a reawakening of interest in our time. We forget this curious decadence of the later seventeenth and eighteenth centuries which did so much to obscure history and especially the history of the sciences. Fortunately the scholars of the sixteenth and early seventeenth centuries accomplished successfully the task of printing many of the books of these old-time physicians and secured their publication in magnificent editions. These were bought eagerly by scholars and libraries all over Europe in spite of the high price they commanded in that era of slow, laborious printing. The Renaissance exhibits some of its most admirable qualities in its reverence for these old workers in science and above all for the careful preparation by its scholars of the text of these first editions of old-time physicians. The works have often been thus literally preserved for us, for some of them at least would have disappeared among the vicissitudes of the intervening time, most of which was anything but favorable to the preservation of old-time works, no matter what their content or value.

During the second and third centuries of our era, while the Talmudic writings were taking shape, three great Jewish physicians came into prominence. The first of them, Chanina, was a contemporary of Galen. According to tradition, as we have said, he inserted both natural and artificial teeth before the close of the second century. The two others were Rab or Raw and Samuel. Rab has the distinction of having studied his anatomy from the human body. According to tradition he did not hesitate to spend large sums of money in order to procure subjects for dissection. At this time it is very doubtful whether Galen, though only of the preceding generation, ever had the opportunity to study more than animals or, at most, a few human bodies. Samuel, the third of the group, was an intimate friend of Rab's, perhaps a disciple, and his fame depends rather on his practice of medicine than of research in medical science. He was noted for his practical development of two specialties that cannot but seem to us rather distant from each other. His reputation as a skilful obstetrician was only surpassed by the estimation in which he was held as an oculist. He seems to have turned to astronomy as a hobby, and was highly honored for his knowledge of this science. Probably there is nothing commoner in the story of great Jewish physicians than their successful pursuit of some scientific subject as a hobby and reaching distinction in it. Their surplus intellectual energy needed an outlet besides their vocation, and they got a rest by turning to some other interest, often accomplishing excellent results in it. Like most great students with a hobby, the majority of them were long-lived. Their lives are a lesson to a generation that fears intellectual overwork.

During the fourth century we have a number of very interesting traditions with regard to a great Jewish physician, Abba Oumna, to whom patients flocked from all over the world. He seems particularly to have been anxious to make his services available to the scholars of his time. He looked upon them as brothers in spirit, fellow-laborers whose investigations were as important as his own and whose labors for mankind he hoped to extend by the helpfulness of his profession. In order that it might be easy for them to come to him without feeling abashed by their poverty, and yet so that they might pay him anything that they thought they were able to, he hung up a box in his anteroom in which each patient might deposit whatever he felt able to give. His kindliness towards men became the foundation for many legends. Needless to say he was often imposed upon, but that seems to have made no difference to him, and he went on straightforwardly doing what he thought he ought to do, regardless of the devious ways of men, even those whom he was generously assisting. While we do not know much of his scientific medicine, we do know that he was a fine example of a practitioner of medicine on the highest professional lines.
