Modern surgery may be said to owe its origin to a school of surgeons, the leaders of whom were educated at Salerno in the early part of the thirteenth century, and who, teaching at various north Italian universities, wrote out their surgical principles and experiences in a series of important contributions to that department of medical science.
The fact that the origin of the school was at Salerno, where, as is well known, Arabian influence counted for much and for which Constantine"s translations of Arabian works proved such a stimulus a century before, makes most students conclude that this later medieval surgical development is simply a continuation of the Arabian surgery that, as we have seen, developed very interestingly during the earlier Middle Ages.
Any such idea, however, is not founded on the realities of the situation, but on an a.s.sumption with regard to the extent of Arabian influence. Gurlt in his "History of Surgery" (Vol. I, page 701) completely contradicts this idea, and says with regard to the first of the great Italian writers on surgery, Rogero, that "though Arabian works on surgery had been brought over to Italy by Constantine Africa.n.u.s a hundred years before Roger"s time, these exercised no influence over Italian surgery in the next century, and there is scarcely a trace of the surgical knowledge of the Arabs to be found in Roger"s works."
It is in the history of medicine particularly that it is possible to trace the true influence of the Arabs on European thought in the later Middle Ages. We have already seen in the chapter on Salerno that Arabian influence did harm to Salernitan medical teaching. The school of Salerno itself had developed simple, dietetic, hygienic, and general remedial measures that included the use of only a comparatively small amount of drugs. Its teachers emphasized nature"s curative powers. With Arabian influence came polypharmacy, distrust of nature, and attempts to cure disease rather than help nature. In surgery, which developed very wonderfully in the thirteenth and fourteenth centuries, Salerno must be credited with the incentive that led up to the marvellous development that came. With this, however, Arabian influence has nothing to do.
Gurlt, besides calling attention to the fact that the author of the first great text-book on the subject not only did not draw his inspiration from Arab sources, insisted that "instead of any Arabisms being found in his [Roger"s] writings many Graecisms occur." The Salernitan school of surgery drank at the fountain-head of Greek surgery. Apart from Greek sources Roger"s book rests entirely upon his own experiences, those of his teachers and his colleagues, and the tradition in surgery that had developed at Salerno. This tradition was entirely from the Greek. Roger himself says in one place, "We have resolved to write out deliberately our methods of operation such as they have been derived from our own experience and that of our colleagues and ill.u.s.trious men."
ROGER, ROLAND, AND THE FOUR MASTERS
Ruggero, or Rogero, who is also known as Rogerio and Rogerus with the adjective Parmensis, or Salernita.n.u.s, of Parma or of Salerno, and often in German and English history simply as Roger, lived at the end of the twelfth or the beginning of the thirteenth century and probably wrote his text-book about 1180. This text-book was, according to tradition, originally drafted for his lessons in surgery at Salerno. It attracted much attention and after being commented on by his pupil Rolando, the work of both of them being subsequently annotated by the Four Masters, this combined work became the basis of modern surgery. Roger was probably born either in Palermo or Parma. There are traditions of his having taught for a while at Paris and at the University of Montpellier, though these are not substantiated. His book was printed at Venice in 1546, and has been lately reprinted by De Renzi in his "Collectio Salernitana."
Roland was a pupil of Roger"s, and the two names that often occur in medieval romance became a.s.sociated in a great historic reality as a consequence of Roland"s commentary on his master"s work, which was a favorite text-book in surgery for a good while in the thirteenth century at Salerno. Some s.p.a.ce will be given to the consideration of their surgical teaching after a few words with regard to some disciples who made a second commentary, adding to the value of the original work.
This is the well-known commentary of the Four Masters, a text-book of surgery written somewhat in the way that we now make text-books in various departments of medicine, that is, by asking men who have made specialties of certain subjects to write on that subject and then bind them all together in a single volume. It represents but another striking reminder that most of our methods are old, not new as we are likely to imagine them. The Four Masters took the works of Roger and Rolando, acknowledged their indebtedness much more completely than do our modern writers on all occasions, I fear, and added their commentaries.
Gurlt says ("Geschichte der Chirurgie," Vol. I, p. 703) that "in spite of the fact that there is some doubt about the names of the authors, this volume const.i.tutes one of the most important sources for the history of surgery of the later Middle Ages and makes it very clear that these writers drew their opinions from a rich experience." It is rather easy to ill.u.s.trate from the quotations given in Gurlt or from the accounts of their teaching in Daremberg or De Renzi some features of this experience that can scarcely fail to be surprising to modern surgeons. For instance, what is to be found in this old text-book of surgery with regard to fractures of the skull is likely to be very interesting to surgeons at all times. One might be tempted to say that fewer men would die every year in prison cells who ought to be in hospitals, if the old-time teaching was taken to heart. For there are rather emphatic directions not to conclude because the scalp is unwounded that there can be no fracture of the skull. Where nothing can be felt care must be exercised in getting the history of the case. For instance, if a man is. .h.i.t by a metal instrument shaped like the clapper of a bell or by a heavy key, or by a rounded instrument made of lead--this would remind one very much of the lead pipe of the modern time, so fruitful of mistakes of diagnosis in head injuries--special care must be taken to look for symptoms in spite of the lack of an external penetrating wound. Where there is good reason to suspect a fracture because of the severity of the injury, the scalp should be incised and a fracture of the cranium looked for carefully. That is carrying the exploratory incision pretty far. If a fracture is found the surgeon should trephine so as to relieve the brain of any pressure of blood that might be affecting it.
There are many warnings, however, of the danger of opening the skull and of the necessity for definitely deciding beforehand that there is good reason for so doing. How carefully their observations had been made and how well they had taken advantage of their opportunities, which were, of course, very frequent in those warlike times when firearms were unknown, hand-to-hand conflict common, and blunt weapons were often used, can be appreciated very well from some of the directions. For instance, they knew of the possibility of fracture by _contrecoup_. They say that "quite frequently though the percussion comes in the anterior part of the cranium, the cranium is fractured on the opposite part."[18] They even seem to have known of accidents such as we now discuss in connection with the laceration of the middle meningeal artery. They warn surgeons of the possibilities of these cases. They tell the story of "a youth who had a very small wound made by a thrown stone and there seemed no serious results or bad signs. He died the next day, however. His cranium was opened and a large amount of black blood was found coagulated about his dura mater."
There are many interesting things said with regard to depressed fractures and the necessity for elevating the bone. If the depressed portion is wedged then an opening should be made with the trephine and an elevating instrument called a spatumen used to relieve the pressure.
Great care should be taken, however, in carrying out this procedure lest the bone of the cranium itself, in being lifted, should injure the soft structures within. The dura mater should be carefully protected from injury as well as the pin. Care should especially be exercised at the brow and the rear of the head and at the commissures (_proram et pupim et commissuras_), since at these points the dura mater is likely to be adherent. Perhaps the most striking expression, the word _infect_ being italicized by Gurlt, is: "In elevating the cranium be solicitous lest you should infect or injure the dura mater."
For wounds of the scalp sutures of silk are recommended because this resists putrefaction and holds the wound edges together. Interrupted sutures about a finger-breadth apart are recommended. "The lower part of the wound should be left open so that the cure may proceed properly."
Red powder was strewed over the wound and the leaf of a plant set above it. In the lower angle of the wound a pledget of lint for drainage purposes was inlaid. Hemorrhage was prevented by pressure, by the binding on of _burnt_ wool firmly, and by the ligature of veins and by the cautery.
There are rather interesting discussions of the prognosis of wounds of the head, especially such as may be determined from general symptoms in this commentary of the Four Masters on Roger"s and Rolando"s treatises.
If an acute febrile condition develops, the wound is mortal. If the patient loses the use of the hands and feet or if he loses his power of direction, or his sensation, the wound is mortal. If a universal paralysis comes on, the wound is mortal. For the treatment of all these wounds careful precautions are suggested. Cold was supposed to be particularly noxious to them. Operations on the head were not to be done in cold weather and, above all, not in cold places. The air where such operations were done must be warmed artificially. Hot plates should surround the patient"s head while the operation was being performed. If this were not possible they were to be done by candlelight, the candle being held as close as possible in a warm room. These precautions are interesting as foreshadowing many ideas of much more modern time and especially indicating how old is the idea that cold may be taken in wounds. In popular medicine this still has its place. Whenever a wound does badly in the winter time patients are sure that they have taken cold. Such popular medical ideas are always derived from supposedly scientific medicine, and until we learned about microbes physicians used the same expressions. We have not got entirely away from them yet.
These old surgeons must have had many experiences with fractures at the base of the skull. Hemorrhages from the mouth and nose, for instance, and from the ears were considered bad signs. They were inclined to suggest that openings into the skull should be discovered by efforts to demonstrate a connection between the mouth and nares and the brain cavity. For instance, in their commentary the Four Masters said: "Let the patient hold his mouth and nostrils tight shut and blow strongly."
If there was any lessening of the pressure or any appearance of air in the wound in the scalp, then a connection between the mouth and nose was diagnosticated. This is ingenious but eminently dangerous because of the infectious material contained in the nasal and oral cavities, so likely to be forced by such pressure into the skull. They were particularly anxious to detect linear fractures. One of their methods of negative diagnosis for fractures of the skull was that if the patient were able to bring his teeth together strongly, or to crack a nut without pain, then there was no fracture present. One of the commentators, however, adds to this "_sed hoc aliquando fallit_--but this sign sometimes fails." Split or crack fractures were also diagnosticated by the method suggested by Hippocrates of pouring some colored fluid over the skull after the bone was exposed, when the linear fracture would show by coloration. The Four Masters suggest a sort of red ink for this purpose.
While they have so much to say about fractures of the skull and insist, over and over again, that though all depressed fractures need treatment and many fissure fractures require trepanation, still great care must be exercised in the selection of cases. They say, for instance, that surgeons who in every serious wound of the head have recourse to the trephine must be looked upon as "fools and idiots" (_idioti et stolidi_). In the light of what we now know about the necessity for absolute cleanliness,--asepsis as we have come to call it,--it is rather startling to note the directions that are given to a surgeon to be observed on the day when he is to do a trepanation. For obvious reasons I prefer to quote it in the Latin: "_Et nota quod die ilia cavendum est medico a coitu et malis cibis aera corrumpentibus, ut sunt allia, cepe, et hujusmodi, et colloquio mulieris menstruosae, et ma.n.u.s ejus debent esse mundae, etc._" My quotation is from Gurlt, Vol. I, p. 707. The directions are most interesting. The surgeon"s hands must be clean, he must avoid the taking of food that may corrupt the air, such as onions, leeks, and the like; must avoid menstruating and other women, and in general must keep himself in a state of absolute cleanliness.
To read a pa.s.sage like this separated from its context and without knowing anything about the wonderful powers of observation of the men from whom it comes, it would be very easy to think that it is merely a set of general directions which they had made on some general principle, perhaps quite foolish in itself. We know, however, that these men had by observation detected nearly every feature of importance in fractures of the skull, their indications and contra-indications for operation and their prognosis. They had antic.i.p.ated nearly everything of importance that has come to be insisted on even in our own time in the handling of these difficult cases. It is not unlikely, therefore, that they had also arrived at the recognition by observations on many patients that the satisfactory after-course of these cases which were operated on by the surgeon after due regard to such meticulous cleanliness as is suggested in the paragraph I have quoted, made it very clear that these aseptic precautions, as we would call them, were extremely important for the outcome of the case and, therefore, were well worth the surgeon"s attention, though they must have required very careful precautions and considerable self-denial. Indeed this whole subject, the virtual antic.i.p.ation of our nineteenth-century principles of aseptic surgery in the thirteenth century, is not a dream nor a far-fetched explanation when one knows enough about the directions that were laid down in the surgical text-books of that time.
THE NORTH ITALIAN SURGEONS
After Roger and Rolando and the Four Masters, who owe the inspiration for their work to Salerno and the south of Italy, comes a group of north Italian surgeons: Bruno da Longoburgo, usually called simply Bruno; Theodoric and his father, Hugo of Lucca, and William of Salicet.
Immediately following them come two names that belong, one almost feels, to a more modern period: Mondino, the author of the first text-book on dissection, and Lanfranc (the disciple of William of Salicet), who taught at Paris and "gave that primacy to French surgery which it maintained all the centuries down to the nineteenth" (Pagel). It might very well be thought that this group of Italian surgeons had very little in their writings that would be of any more than antiquarian interest for the modern time. It needs but a little knowledge of their writings as they have come down to us to show how utterly false any such opinion is. To Hugo da Lucca and his son Theodoric we owe the introduction and the gradual bringing into practical use of various methods of anaesthesia. They used opium and mandragora for this purpose and later employed an inhalant mixture, the composition of which is not absolutely known. They seem, however, to have been very successful in producing insensibility to pain for even rather serious and complicated and somewhat lengthy operations. Indeed it is to this that must be attributed most of their surprising success as surgeons at this early date.
We are so accustomed to think that anaesthesia was discovered about the middle of the nineteenth century in America that we forget that literature is full of references in Tom Middleton"s (seventeenth century) phrase to "the mercies of old surgeons who put their patients to sleep before they cut them." Anaesthetics were experimented with almost as zealously, during the latter half of the thirteenth century at least, as during the latter half of the nineteenth century. They were probably not as successful as we are, but they did succeed in producing insensibility to pain, otherwise they could never have operated to the extent they did. Moreover the traditions show that the Da Luccas particularly had invented a method that left very little to be desired in this matter of anaesthesia. A reference to the sketch of Guy de Chauliac in this volume will show how practical the method was in his time.
Nearly the same story as with regard to anaesthetics has to be repeated for what are deemed so surely modern developments,--asepsis and antisepsis. I have already suggested that Roger seems to have known how extremely important it was to approach operations upon the skull with the most absolute cleanliness. There are many hints of the same kind in other writers which show that this was no mere accidental remark, but was a definite conclusion derived from experience and careful observation of results. We find much more with regard to this same subject in the writings of the group of northern Italian surgeons and especially in the group of those a.s.sociated with William of Salicet.
Professor Clifford Allb.u.t.t, Regius Professor of Medicine at the University of Cambridge, England, in his address before the St. Louis World"s Fair Congress of Arts and Science in 1904, did not hesitate to declare that William discussed the causes for union by first intention and the modes by which it might be obtained. He, too, insisted on cleanliness as the most important factor in having good surgical results, and all of this group of men, in operating upon septic cases, used stronger wine as a dressing. This exerted, as will be readily understood, a very definite antiseptic quality.
Evidently some details of the teaching of this group of great surgeons in northern Italy in the second half of the thirteenth century will make clearer to us how much the rising universities of the time were accomplishing in medicine and surgery as well as in their other departments. The dates of the origin of some of these universities should perhaps be recalled so as to remind readers how closely related they are to this great group of surgical teachers. Salerno was founded very early, probably in the tenth century, Bologna, Reggio, and Modena came into existence toward the end of the twelfth century; Vicenza, Padua, Naples, Vercelli, and Piacenza, as well as Arezzo, during the first half of the thirteenth century; Rome, Perugia, Trevizo, Pisa, Florence, Sienna, Lucca, Pavia, and Ferrara during the next century. The thirteenth century was the special flourishing period of the universities, and the medical departments, far from being behind, were leaders in accomplishment. (See my "The Thirteenth Greatest of Centuries," N.Y., 1908.)
BRUNO DA LONGOBURGO
The first of this important group of north Italian surgeons who taught at these universities was Bruno of Longoburgo. While he was born in Calabria, and probably studied in Salerno, his work was done at Vicenza, Padua, and Verona. His text-book, the "Chirurgia Magna," dedicated to his friend Andrew of Piacenza, was completed at Padua in January, 1252.
Gurlt notes that he is the first of the Italian surgeons who quotes, besides the Greeks, the Arabian writers on surgery. Eclecticism had definitely come into vogue to replace exclusive devotion to the Greek authors, and men were taking what was good wherever they found it. Gurlt tells us that Bruno owed much of what he wrote to his own experience and observation. He begins his work by a definition of surgery, _chirurgia_, tracing it to the Greek and emphasizing that it means handwork. He then declares that it is the last instrument of medicine to be used only when the other two instruments, diet and potions, have failed. He insists that surgeons must learn by seeing surgical operations and watching them long and diligently. They must be neither rash nor over bold and should be extremely cautious about operating. While he says that he does not object to a surgeon taking a gla.s.s of wine, the followers of this specialty must not drink to such an extent as to disturb their command over themselves, and they must not be habitual drinkers. While all that is necessary for their art cannot be learned out of books, they must not despise books however, for many things can be learned readily from books, even about the most difficult parts of surgery. Three things the surgeon has to do:--"to bring together separated parts, to separate those that have become abnormally united, and to extirpate what is superfluous."
In his second chapter on healing he talks about healing by first and second intention. Wounds must be more carefully looked to in summer than in winter, because _putrefactio est major in aestate quam in hyeme_, putrefaction is greater in summer than in winter. For proper union care must be exercised to bring the wound edges accurately together and not allow hair, or oil, or dressings to come between them. In large wounds he considers st.i.tching indispensable, and recommends for this a fine, square needle. The preferable suture material in his experience was silk or linen.
The end of the wound was to remain open in order that lint might be placed therein in order to draw off any objectionable material. He is particularly insistent on the necessity for drainage. In deep wounds special provision must be made, and in wounds of extremities the limb must be so placed as to encourage drainage. If drainage does not take place, then either the wound must be thoroughly opened, or if necessary a counter opening must be made to provide drainage. All his treatment of wounds is dry, however. Water, he considered, always did harm. We can readily understand that the water generally available and especially as surgeons saw it in camps and on the battlefield, was likely to do much more harm than good. In penetrating wounds of the belly cavity, if there was difficulty in bringing about the reposition of the intestines, they were first to be pressed back with a sponge soaked in warm wine. Other manipulations are suggested, and if necessary the wound must be enlarged. If the omentum finds its way out of the wound, all of it that is black or green must be cut off. In cases where the intestines are wounded they are to be sewed with a small needle and a silk thread and care is to be exercised in bringing about complete closure of the wound.
This much will give a good idea of Bruno"s thoroughness. Altogether, Gurlt, in his "History of Surgery," gives about fifteen large octavo pages of rather small type to a _brief_ compendium of Bruno"s teachings.
One or two other remarks of Bruno are rather interesting in the light of modern developments in medicine. For instance, he suggests the possibility of being able to feel a stone in the bladder by means of bimanual palpation. He teaches that mothers may often be able to cure hernias, both umbilical and inguinal, in children by promptly taking up the treatment of them as soon as noticed, bringing the edges of the hernial opening together by bandages and then preventing the reopening of the hernia by prohibiting wrestling and loud crying and violent motion. He has seen overgrowth of the mamma in men, and declares that it is due to nothing else but fat, as a rule. He suggests if it should hang down and be in the way on account of its size it should be extirpated.
He seems to have known considerable about the lipomas and advises that they need only be removed in case they become bothersomely large. The removal is easy, and any bleeding that takes place may be stopped by means of the cautery. He divides rectal fistulae into penetrating and non-penetrating, and suggests salves for the non-penetrating and the actual cautery for those that penetrate. He warns against the possibility of producing incontinence by the incision of deep fistulae, for this would leave the patient in a worse state than before.
HUGH OF LUCCA
Bruno brought up with him the methods and principles of surgery from the south of Italy, but there seems to have been already in the north at least one distinguished surgeon who had made his mark. This was Ugo da Lucca or Ugo Lucca.n.u.s, sometimes known in the modern times in German histories of medicine as Hugo da Lucca and in English, Hugh of Lucca. He flourished early in the thirteenth century. In 1214 he was called to Bologna to become the city physician, and joined the Bolognese volunteers in the crusade in 1218, being present at the siege of Damietta. He returned to Bologna in 1221 and was given the post of legal physician to the city. The civic statutes of Bologna are, according to Gurlt, the oldest monument of legal medicine in the Middle Ages. Ugo died not long after the middle of the century, and is said to have been nearly one hundred years old. Of his five sons, three became physicians.
The most celebrated of these was Theodoric, who wrote a text-book of surgery in which are set down the traditions of surgery that had been practised in his father"s life. Theodoric is especially enthusiastic in praise of his father, because he succeeded in bringing about such perfect healing of wounds with only wine and water and the ligature and without the employment of any ointments.
Ugo seems to have occupied himself much with chemistry. To him we owe a series of discoveries with regard to anodyne and anaesthetizing drugs. He is said to have been the first who taught the sublimation of a.r.s.enic.
Unfortunately he left no writings after him, and all that we know of him we owe to the filial devotion of his son Theodoric.
THEODORIC
This son, after having completed his medical studies at the age of about twenty-three, entered the Dominican Order, then only recently established, but continued his practice of medicine undisturbed. His ecclesiastical preferment was rapid. He attracted the attention of the Bishop of Valencia, and became his chaplain in Rome. At the age of about fifty he was made a bishop in South Italy and later transferred to the Bishopric of Cervia, not far from Ravenna. Most of his life seems to have been pa.s.sed in Bologna however, and he continued to practise medicine, devoting his fees, however, entirely to charity. His text-book of surgery was written about 1266 and is signed with his full name and t.i.tle as Bishop of Cervia. Even at this time however, he still retained the custom of designating himself as a member of the Dominican Order.
The most interesting thing in the first book of his surgery is undoubtedly his declaration that all wounds should be treated only with wine and bandaging. Wine he insists on as the best possible dressing for wounds. It was the most readily available antiseptic that they had at that time, and undoubtedly both his father"s recommendation of it and his own favorable experience with it were due to this quality. It must have acted as an excellent inhibitive agent of many of the simple forms of pus formation. At the conclusion of this first book he emphasizes that it is extremely important for the healing of wounds that the patient should have good blood, and this can only be obtained from suitable nutrition. It is essential therefore for the physician to be familiar with the foods which produce good blood in order that his wounded patients may be fed appropriately. He suggests, then, a number of articles of diet which are particularly useful in producing such a favorable state of the tissues as will bring about the rebirth of flesh and the adhesion of wound surfaces. Shortly before he emphasizes the necessity for not injuring nerves, though if nerves have been cut they should be brought together as carefully as possible, the wound edges being then approximated.
Probably the most interesting feature for our generation of the great text-books of the surgeons of the medieval universities is the occurrence in them of definite directions for securing union in surgical wounds, at least by first intention and their insistence on keeping wounds clear. The expression union by first intention comes to us from the olden time. They even boasted that the scars left after their incisions were often so small as to be scarcely noticeable. Such expressions of course could only have come from men who had succeeded in solving some of the problems of antisepsis that were solved once more in the generation preceding our own. With regard to their treatment of wounds, Professor Clifford Allb.u.t.t says:[19]
"They washed the wound with wine, scrupulously removing every foreign particle; then they brought the edges together, not allowing wine nor anything else to remain within--dry adhesive surfaces were their desire. Nature, they said, produces the means of union in a viscous exudation, or natural balm, as it was afterwards called by Paracelsus, Pare, and Wurtz. In older wounds they did their best to obtain union by cleansing, desiccation, and refreshing of the edges. Upon the outer surface they laid only lint steeped in wine. Powders they regarded as too desiccating, for powder shuts in decomposing matters wine after washing, purifying, and drying the raw surfaces evaporates."
Theodoric comes nearest to us of all these old surgeons. The surgeon who in 1266 wrote: "For it is not necessary, as Roger and Roland have written, as many of their disciples teach, and as all _modern_ surgeons profess, that pus should be generated in wounds. No error can be greater than this. Such a practice is indeed to hinder nature, to prolong the disease, and to prevent the conglutination and consolidation of the wound" was more than half a millennium ahead of his time. The italics in the word modern are mine, but might well have been used by some early advocate of antisepsis or even by Lord Lister himself. Just six centuries almost to the year would separate the two declarations, yet they would be just as true at one time as at another. When we learn that Theodoric was proud of the beautiful cicatrices which he obtained without the use of any ointment, _pulcherrimas cicatrices sine unguento aliquo inducebat_, then further that he impugned the use of poultices and of oils on wounds, while powders were too drying and besides had a tendency to prevent drainage, the literal meaning of the Latin words _saniem incarcerare_ is to "incarcerate sanious material," it is easy to understand that the claim that antiseptic surgery was antic.i.p.ated six centuries ago is no exaggeration and no far-fetched explanation with modern ideas in mind of certain clever modes of dressing hit upon accidentally by medieval surgeons.
Theodoric"s treatment of many practical problems is interesting for the modern time. For instance, in his discussion of cancer he says that there are two forms of the affection. One of them is due to a melancholy humor, a const.i.tutional tendency as it were, and occurs especially in the b.r.e.a.s.t.s of women or latent in the womb. This is difficult of treatment and usually fatal. The other cla.s.s consists of a deep ulcer with undermined edges, occurring particularly on the legs, difficult to cure and ready of relapse, but for which the outlook is not so bad. His description of _noli me tangere_ and of lupus is rather practical. Lupus is "eating herpes," occurs mainly on the nose, or around the mouth, slowly increases, and either follows a preceding erysipelas or comes from some internal cause. _Noli me tangere_ is a corroding ulcer, so called perhaps because irritation of it causes it to spread more rapidly. He thinks that deep cauterization of it is the best treatment. Since these are in the department of skin diseases this seems the place to mention that Theodoric describes salivation as occurring after the use of mercury for certain skin diseases. He has already shown that he knows of certain genital ulcers and sores on the genital regions and of distinctions between them.
WILLIAM OF SALICET
The third of the great surgeons in northern Italy was William of Salicet. He was a pupil of Bruno"s and the master of Lanfranc. The first part of his life was pa.s.sed at Bologna and the latter part as the munic.i.p.al and hospital physician of Verona. He probably died about 1280.
He was a physician as well as a surgeon and was one of those who insisted that the two modes of practising medicine should not be separated, or if they were both medicine and surgery would suffer. He thought that the physician learned much by seeing the interior of the body during life, while the surgeon was more conservative if he were a physician. It is curiously interesting to find that the Regius Professors at both Oxford and Cambridge in our time have expressed themselves somewhat similarly. Professor Clifford Allb.u.t.t is quite emphatic in this matter and Professor Osler is on record to the same effect. Following Theodoric, William of Salicet did much to get away from the Arabic abuse of the cautery and brought the knife back to its proper place again as the ideal surgical instrument. Unlike those who had written before him, William quoted very little from preceding writers. Whenever he quotes his contemporaries it is in order to criticise them. He depended on his own experience and considered that it was only what he had actually learned from experience that he should publish for the benefit of others.
A very good idea of the sort of surgery that William of Salicet practised may be obtained even from the beginning of the first chapter of his first book. This is all with regard to surgery of the head. He begins with the treatment of hydrocephalus or, as he calls it, "water collected in the heads of children newly born." He rejects opening of the head by an incision because of the danger of it. In a number of cases, however, he had had success by puncturing the scalp and membranes with a cautery, though but a very small opening was made and the fluid was allowed to escape only drop by drop. He then takes up eye diseases, a department of surgery rather well developed at that time, as can be seen from our account of the work of Pope John XXI as an ophthalmologist during the thirteenth century. See _Ophthalmology_ (January, 1909), reprinted in "Catholic Churchmen in Science,"
Philadelphia, The Dolphin Press, 1909.
William devotes six chapters to the diseases of the eyes and the eyelids. Then there are two chapters on affections of the ears. Foreign bodies and an acc.u.mulation of ear wax are removed by means of instruments. A polyp is either cut off or its pedicle bound with a ligature, and it is allowed to shrivel. The next chapter is on the nose.
Nasal polyps were to be grasped with a sharp tenaculum, _c.u.m tenacillis acutis_, and either wholly or partially extracted. Ranula was treated by being lifted well forward by means of a sharp iron hook and then split with a razor. It is evident that the tendency of these to fill up again was recognized, and accordingly it was recommended that vitriol powder, or alum with salt, be placed in the cavity for a time after evacuation in order to produce adhesive inflammation.
In the same chapter on the mouth one finds that William did not hesitate to perform what cannot but be considered rather extensive operations within the oral cavity. For instance, he tells of removing a large epulis and gives an account in detail of the case. To quote his own words: "I cured a certain woman from Piacenza who was suffering from fleshy tumor on the gums of the upper jaw, the tumor having grown to such a size above the teeth and the gums that it was as large or perhaps larger than a hen"s egg. I removed it at four operations by means of heated iron instruments. At the last operation I removed the teeth that were loose with certain parts of the jawbone."
