Galen - wikipedia Galen For other uses, see Galen ( disambiguation ). Galen of Pergamon Eighteenth - century portrait by Georg Paul Busch September 129 AD Pergamon c. 210 AD Occupation Physician Aelius Galenus or Claudius Galenus ( / ɡəˈliːnəs / ; Greek : Κλαύδιος Γαληνός ; September 129 AD -- c. 200 / c. 216 ), often Anglicized as Galen and better known as Galen of Pergamon ( / ˈɡeɪlən / ), was a prominent Greek physician, surgeon and philosopher in the Roman Empire. Arguably the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic. The son of Aelius Nicon, a wealthy architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher. Born in Pergamon ( present - day Bergama, Turkey ), Galen traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome, where he served prominent members of Roman society and eventually was given the position of personal physician to several emperors. Galen 's understanding of anatomy and medicine was principally influenced by the then - current theory of humorism ( also known as the four humors -- black bile, yellow bile, blood, and phlegm ), as advanced by ancient Greek physicians such as Hippocrates. His theories dominated and influenced Western medical science for more than 1,300 years. His anatomical reports, based mainly on dissection of monkeys, especially the Barbary macaque, and pigs, remained uncontested until 1543, when printed descriptions and illustrations of human dissections were published in the seminal work De humani corporis fabrica by Andreas Vesalius where Galen 's physiological theory was accommodated to these new observations. Galen 's theory of the physiology of the circulatory system endured until 1221, when Ibn al - Nafis published his encyclopedia of medicine entitled As - Shamil fi Tibb, in which he established that blood circulates, with the heart acting as a pump. Galen saw himself as both a physician and a philosopher, as he wrote in his treatise entitled That the Best Physician Is Also a Philosopher. Galen was very interested in the debate between the rationalist and empiricist medical sects, and his use of direct observation, dissection and vivisection represents a complex middle ground between the extremes of those two viewpoints. Many of his works have been preserved and / or translated from the original Greek, although many were destroyed and some credited to him are believed to be spurious. Although there is some debate over the date of his death, he was no younger than seventy when he died. In medieval Europe, Galen 's writings on anatomy became the mainstay of the medieval physician 's university curriculum, but by that time they suffered greatly from stasis and intellectual stagnation. Some of Galen 's ideas were incorrect : he did not dissect a human body, nor did the medieval lecturers. Galen 's original Greek texts gained renewed prominence during the early modern period. In the 1530s, Belgian anatomist and physician Andreas Vesalius took on a project to translate many of Galen 's Greek texts into Latin. Vesalius 's most famous work, De humani corporis fabrica, was greatly influenced by Galenic writing and form.

Galen describes his early life in On the affections of the mind. He was born in September AD 129 ; his father, Aelius Nicon, was a wealthy patrician, an architect and builder, with eclectic interests including philosophy, mathematics, logic, astronomy, agriculture and literature. Galen describes his father as a `` highly amiable, just, good and benevolent man ''. At that time Pergamon ( modern - day Bergama, Turkey ) was a major cultural and intellectual centre, noted for its library, second only to that in Alexandria, and attracted both Stoic and Platonic philosophers, to whom Galen was exposed at age 14. His studies also took in each of the principal philosophical systems of the time, including Aristotelian and Epicurean. His father had planned a traditional career for Galen in philosophy or politics and took care to expose him to literary and philosophical influences. However, Galen states that in around AD 145 his father had a dream in which the god Asclepius ( Aesculapius ) appeared and commanded Nicon to send his son to study medicine. Again, no expense was spared, and following his earlier liberal education, at 16 he began studies at the prestigious local sanctuary or Asclepieum dedicated to Asclepius, god of medicine, as a θεραπευτής ( therapeutes, or attendant ) for four years. There he came under the influence of men like Aeschrion of Pergamon, Stratonicus and Satyrus. Asclepiea functioned as spas or sanitoria to which the sick would come to seek the ministrations of the priesthood. Romans frequented the temple at Pergamon in search of medical relief from illness and disease. It was also the haunt of notable people such as Claudius Charax the historian, Aelius Aristides the orator, Polemo the sophist, and Cuspius Rufinus the Consul. In 148, when he was 19, his father died, leaving him independently wealthy. He then followed the advice he found in Hippocrates ' teaching and travelled and studied widely including such destinations as Smyrna ( now Izmir ), Corinth, Crete, Cilicia ( now Çukurova ), Cyprus, and finally the great medical school of Alexandria, exposing himself to the various schools of thought in medicine. In 157, aged 28, he returned to Pergamon as physician to the gladiators of the High Priest of Asia, one of the most influential and wealthy men in Asia. Galen claims that the High Priest chose him over other physicians after he eviscerated an ape and challenged other physicians to repair the damage. When they refused, Galen performed the surgery himself and in so doing won the favor of the High Priest of Asia. Over his four years there, he learned the importance of diet, fitness, hygiene and preventive measures, as well as living anatomy, and the treatment of fractures and severe trauma, referring to their wounds as `` windows into the body ''. Only five deaths among the gladiators occurred while he held the post, compared to sixty in his predecessor 's time, a result that is in general ascribed to the attention he paid to their wounds. At the same time he pursued studies in theoretical medicine and philosophy. Later years : AD 162 -- 217 Modern statue of Galen in his home town, Pergamon Galen went to Rome in 162 and made his mark as a practicing physician. His impatience brought him into conflict with other doctors and he felt menaced by them. His demonstrations there antagonized the less skilled and more conservative physicians in the city. When Galen 's animosity with the Roman medical practitioners became serious, he feared he might be exiled or poisoned, so he left the city. Rome had engaged in foreign wars in 161 ; Marcus Aurelius and his colleague Lucius Verus were in the north fighting the Marcomanni. During the autumn of 169 when Roman troops were returning to Aquileia, a great plague broke out, and the emperor summoned Galen back to Rome. He was ordered to accompany Marcus and Verus to Germany as the court physician. The following spring Marcus was persuaded to release Galen after receiving a report that Asclepius was against the project. He was left behind to act as physician to the imperial heir Commodus. It was here in court that Galen wrote extensively on medical subjects. Ironically, Lucius Verus died in 169, and Marcus Aurelius himself died in 180, both victims of the plague. Galen was the physician to Commodus for much of the emperor 's life and treated his common illnesses. According to Dio Cassius 72.14. 3 -- 4, in about 189, under Commodus ' reign, a pestilence occurred which at its height killed 2,000 people a day in Rome. This was most likely the same plague that struck Rome during Marcus Aurelius ' reign. Galen became physician to Septimius Severus during his reign in Rome. Galen compliments Severus and Caracalla on keeping a supply of drugs for their friends and mentions three cases in which they had been of use in 198. The Antonine plague Main article : Antonine Plague The ' Galen ' group of physicians in an image from the Vienna Dioscurides ; he is depicted top center. The Antonine Plague was named after Marcus Aurelius ' family name of Antoninus. It was also known as the Plague of Galen and held an important place in medicinal history because of its association with Galen. He had first - hand knowledge of the disease, and was present in Rome when it first struck in 166 AD, and was also present in the winter of 168 -- 69 during an outbreak among troops stationed at Aquileia. He had experience with the epidemic, referring to it as very long lasting, and described its symptoms and his treatment of it. Unfortunately, his references to the plague are scattered and brief. Galen was not trying to present a description of the disease so that it could be recognized in future generations ; he was more interested in the treatment and physical effects of the disease. For example, in his writings about a young man afflicted with the plague, he concentrated on the treatment of internal and external ulcerations. According to Niebuhr, `` this pestilence must have raged with incredible fury ; it carried off innumerable victims. The ancient world never recovered from the blow inflicted upon it by the plague that visited it in the reign of M. Aurelius. '' The mortality rate of the plague was 7 -- 10 percent ; the outbreak in 165 -- 168 would have caused approximately 3.5 to 5 million deaths. Otto Seeck believes that over half the population of the empire perished. J.F. Gilliam believes that the Antonine plague probably caused more deaths than any other epidemic during the empire before the mid-3rd century. It is believed that the Antonine Plague was smallpox, because though his description is incomplete, Galen gave enough information to enable a firm identification of the disease. Galen notes that the exanthema covered the victim 's entire body and was usually black. The exanthem became rough and scabby where there was no ulceration. He states that those that were going to survive developed a black exanthem. According to Galen, it was black because of a remnant of blood putrefied in a fever blister that was pustular. His writings state that raised blisters were present in the Antonine plague, usually in the form of a blistery rash. Galen states that the skin rash was close to the one Thucydides described. Galen describes symptoms of the alimentary tract via a patient 's diarrhea and stools. If the stool was very black, the patient died. He says that the amount of black stools varied. It depended on the severity of the intestinal lesions. He observes that in cases where the stool was not black, the black exanthema appeared. Galen describes the symptoms of fever, vomiting, fetid breath, catarrh, cough, and ulceration of the larynx and trachea. Eudemus When the Peripatetic philosopher Eudemus became ill with quartan fever, Galen felt obliged to treat him `` since he was my teacher and I happened to live nearby. '' Galen wrote : `` I return to the case of Eudemus. He was thoroughly attacked by the three attacks of quartan ague, and the doctors had given him up, as it was now mid-winter. '' Some Roman physicians criticized Galen for his use of the prognosis in his treatment of Eudemus. This practice conflicted with the then - current standard of care, which relied upon divination and mysticism. Galen retaliated against his detractors by defending his own methods. Garcia - Ballester quotes Galen as saying : `` In order to diagnose, one must observe and reason. This was the basis of his criticism of the doctors who proceeded alogos and askeptos. '' However, Eudemus warned Galen that engaging in conflict with these physicians could lead to his assassination. `` Eudemus said this, and more to the same effect ; he added that if they were not able to harm me by unscrupulous conduct they would proceed to attempts at poisoning. Among other things he told me that, some ten years before, a young man had come to the city and had given, like me practical demonstrations of the resources of our art ; this young man was put to death by poison, together with two servants who accompanied him. '' Garcia - Ballester says the following of Galen 's use of prognosis : `` In modern medicine, we are used to distinguishing between the diagnostic judgment ( the scientific knowledge of what a patient has ) and the prognostic judgment ( the conjecture about what will happen to him. ) Galen, like the Hippocratics, was not. For him, to understand a clinical case technically, ' to diagnose ', was, among other things, to know with greater or lesser certainty the outcome for the patient, ' to prognosticate '. Prognosis, then, is one of the essential problems and most important objectives of Galenic diagnosis. Galen was concerned to distinguish it from divination or prophecy, both to improve diagnosis technically and to enhance the physician 's reputation. '' Death The 11th - century Suda lexicon states that Galen died at the age of 70, which would place his death in about the year 199. However, there is a reference in Galen 's treatise `` On Theriac to Piso '' ( which may, however, be spurious ) to events of 204. There are also statements in Arabic sources that he died in Sicily at age 87, after 17 years studying medicine and 70 practicing it, which would mean he died about 217. According to these sources, the tomb of Galenus in Palermo was still well preserved in tenth century. Nutton believes that `` On Theriac to Piso '' is genuine, that the Arabic sources are correct, and that the Suda has erroneously interpreted the 70 years of Galen 's career in the Arabic tradition as referring to his whole lifespan. Boudon - Millot more or less concurs and favours a date of 216. Contributions to medicine Further information : humors Galen contributed a substantial amount to the Hippocratic understanding of pathology. Under Hippocrates ' bodily humors theory, differences in human moods come as a consequence of imbalances in one of the four bodily fluids : blood, yellow bile, black bile, and phlegm. Galen promoted this theory and the typology of human temperaments. In Galen 's view, an imbalance of each humor corresponded with a particular human temperament ( blood -- sanguine, black bile -- melancholic, yellow bile -- choleric, and phlegm -- phlegmatic ). Thus, individuals with sanguine temperaments are extroverted and social ; choleric people have energy, passion, and charisma ; melancholics are creative, kind, and considerate ; and phlegmatic temperaments are characterized by dependability, kindness, and affection. Galen dissecting a monkey, as imagined by Veloso Salgado in 1906 Galen 's principal interest was in human anatomy, but Roman law had prohibited the dissection of human cadavers since about 150 BC. Because of this restriction, Galen performed anatomical dissections on living ( vivisection ) and dead animals, mostly focusing on pigs and primates. This work was useful because Galen believed that the anatomical structures of these animals closely mirrored those of humans. Galen clarified the anatomy of the trachea and was the first to demonstrate that the larynx generates the voice. In one experiment, Galen used bellows to inflate the lungs of a dead animal. Galen 's work on the anatomy remained largely unsurpassed and unchallenged up until the 16th century in Europe. In the middle of the 16th century, the anatomist Andreas Vesalius challenged the anatomical knowledge of Galen by conducting dissections on human cadavers. These investigations allowed Vesalius to refute aspects of Galen 's anatomy. Among Galen 's major contributions to medicine was his work on the circulatory system. He was the first to recognize that there are distinct differences between venous ( dark ) and arterial ( bright ) blood. Although his anatomical experiments on animal models led him to a more complete understanding of the circulatory system, nervous system, respiratory system, and other structures, his work contained scientific errors. Galen believed the circulatory system to consist of two separate one - way systems of distribution, rather than a single unified system of circulation. He believed venous blood to be generated in the liver, from where it was distributed and consumed by all organs of the body. He posited that arterial blood originated in the heart, from where it was distributed and consumed by all organs of the body. The blood was then regenerated in either the liver or the heart, completing the cycle. Galen also believed in the existence of a group of blood vessels he called the rete mirabile in the carotid sinus. Both of these theories of the circulation of blood were later shown to be incorrect by Ibn al - Nafis. In his work De motu musculorum, Galen explained the difference between motor and sensory nerves, discussed the concept of muscle tone, and explained the difference between agonists and antagonists. Galen was a skilled surgeon, operating on human patients. Many of his procedures and techniques would not be used again for centuries, such as the procedures he performed on brains and eyes. To correct cataracts in patients, Galen performed an operation similar to a modern one. Using a needle - shaped instrument, Galen attempted to remove the cataract - affected lens of the eye. His surgical experiments included ligating the arteries of living animals. Although many 20th century historians have claimed that Galen believed the lens to be in the exact center of the eye, Galen actually understood that the crystalline lens is located in the anterior aspect of the human eye. At first reluctantly but then with increasing vigour, Galen promoted Hippocratic teaching, including venesection and bloodletting, then unknown in Rome. This was sharply criticised by the Erasistrateans, who predicted dire outcomes, believing that it was not blood but pneuma that flowed in the veins. Galen, however, staunchly defended venesection in his three books on the subject and in his demonstrations and public disputations. Contributions to philosophy See also : Philosophy of medicine Although the main focus of his work was on medicine, anatomy, and physiology, Galen also wrote about logic and philosophy. His writings were influenced by earlier Greek and Roman thinkers, including Plato, Aristotle, and the Stoics. Galen was concerned to combine philosophical thought with medical practice, as in his brief work That the Best Physician is also a Philosopher. He took aspects from each group and combined them with his original thought. He regarded medicine as an interdisciplinary field that was best practiced by utilizing theory, observation, and experimentation in conjunction. Several schools of thought existed within the medical field during Galen 's lifetime, the main two being the Empiricists and Rationalists ( also called Dogmatists or Philosophers ), with the Methodists being a smaller group. The Empiricists emphasized the importance of physical practice and experimentation, or `` active learning '' in the medical discipline. In direct opposition to the Empiricists were the Rationalists, who valued the study of established teachings in order to create new theories in the name of medical advancements. The Methodists formed somewhat of a middle ground, as they were not as experimental as the Empiricists, nor as theoretical as the Rationalists. The Methodists mainly utilized pure observation, showing greater interest in studying the natural course of ailments than making efforts to find remedies. Galen 's education had exposed him to the five major schools of thought ( Platonists, Peripatetics, Stoics, Epicureans, Pyrrhonists ), with teachers from the Rationalist sect and from the Empiricist sect. Opposition to the Stoics Galen was well known for his advancements in the medical field and the circulatory system ; he was also involved with philosophy. He developed his own tripartite soul model following the examples of Plato ; some scholars reference him as a Platonist. Galen would not have agreed with this claim because he was primarily a scientist and all of his claims could be supported by scientific evidence ; Plato was purely a philosopher. He also developed his own personality theory which was connected to liquids in the body, and believed that there was a physiological basis for mental disorders. Lastly, he connected many of his theories to the pneuma, which is where he most strongly opposed the Stoics definition and use of the pneuma. The Stoics, according to Galen, failed to give a credible answer for the localization of functions of the psyche, or the mind. Through his use of medicine, he was convinced that he came up with a better answer, the brain. The Stoics only recognized the soul as having one part, which was the rational soul and they claimed it would be found in the heart. Galen, following Plato 's idea, came up with two more parts to the soul. Galen also rejected Stoic propositional logic and instead embraced a hypothetical syllogistic which was strongly influenced by the Peripatetics and based on elements of Aristotelian logic. Localization of function One of Galen 's major works, On the Doctrines of Hippocrates and Plato, sought to demonstrate the unity of the two subjects and their views. Using their theories, combined with Aristotle 's, Galen developed a tripartite soul consisting of similar aspects. He used the same terms as Plato, referring to the three parts as rational, spiritual, and appetitive. Each corresponded to a localized area of the body. The rational soul was in the brain, the spiritual soul was in the heart, and the appetitive soul was in the liver. Galen was the first scientist and philosopher to assign specific parts of the soul to locations in the body because of his extensive background in medicine. This idea is now referred to as localization of function. Galen 's assignments were revolutionary for the time period, which set the precedent for future localization theories. Galen believed each part of this tripartite soul controlled specific functions within the body and that the soul, as a whole, contributed to the health of the body, strengthening the `` natural functioning capacity of the organ or organs in question ''. The rational soul controlled higher level cognitive functioning in an organism, for example, making choices or perceiving the world and sending those signals to the brain. He also listed `` imagination, memory, recollection, knowledge, thought, consideration, voluntary motion and sensation '' as being found within the rational soul. The functions of `` growing or being alive '' resided in the spirited soul. The spirited soul also contained our passions, such as anger. These passions were considered to be even stronger than regular emotions, and, as a consequence, more dangerous. The third part of the soul, or the appetitive spirit, controlled the living forces in our body, most importantly blood. The appetitive spirit also regulated the pleasures of the body and was moved by feelings of enjoyment. This third part of the soul is the animalistic, or more natural, side of the soul, it deals with the natural urges of the body and survival instincts. Galen proposed that when the soul is moved by too much enjoyment, it reaches states of `` incontinence '' and `` licentiousness '', the inability to willfully cease enjoyment, which was a negative consequence of too much pleasure. In order to unite his theories about the soul and how it operated within the body, he adapted the theory of the pneuma, which he used to explain how the soul operated within its assigned organs, and how those organs, in turn, interacted together. Galen then distinguished the vital pneuma, in the arterial system, from the psychic pneuma, in the brain and nervous system. Galen placed the vital pneuma in the heart and the psychic pneuma within the brain. He conducted many anatomical studies on animals, most famously an ox, to study the transition from vital to psychic pneuma. Although highly criticized for comparing animal anatomy to human anatomy, Galen was convinced that his knowledge was abundant enough in both anatomies to base one on the other. Mind -- body problem Further information : Mind -- body problem Galen believed there to be no distinction between the mental and the physical. This was a controversial argument of the time, and Galen fell with the Greeks in believing that the mind and body were not separate faculties. He believed that this could be scientifically proven. This was where his opposition to the Stoics became most prevalent. Galen proposed organs within the body to be responsible for specific functions, rather than individual parts. According to Galen, the Stoics ' lack of scientific justification discredited their claims of the separateness of mind and body, which is why he spoke so strongly against them. Psychotherapy Another one of Galen 's major works, On the Diagnosis and Cure of the Soul 's Passion, discussed how to approach and treat psychological problems. This was Galen 's early attempt at what would later be called psychotherapy. His book contained directions on how to provide counsel to those with psychological issues to prompt them to reveal their deepest passions and secrets, and eventually cure them of their mental deficiency. The leading individual, or therapist, had to be a male, preferably of an older, wiser, age, as well as free from the control of the passions. These passions, according to Galen, caused the psychological problems that people experienced. Published works Main article : Galenic corpus De curandi ratione Galenou apanta ( 1538 ) Galen may have produced more work than any author in antiquity, rivaling the quantity of work issued from Augustine of Hippo. So profuse was Galen 's output that the surviving texts represent nearly half of all the extant literature from ancient Greece. It has been reported that Galen employed twenty scribes to write down his words. Galen may have written as many as 500 treatises, amounting to some 10 million words. Although his surviving works amount to some 3 million words, this is thought to represent less than a third of his complete writings. In AD 191, a fire in the Temple of Peace destroyed many of his works, in particular treatises on philosophy. Because Galen 's works were not translated into Latin in the ancient period, and because of the collapse of the Roman Empire in the West, the study of Galen, along with the Greek medical tradition as a whole, went into decline in Western Europe during the Early Middle Ages, when very few Latin scholars could read Greek. However, in general, Galen and the ancient Greek medical tradition continued to be studied and followed in the Eastern Roman Empire, commonly known as the Byzantine Empire. All of the extant Greek manuscripts of Galen were copied by Byzantine scholars. In the Abbasid period ( after AD 750 ) Arab Muslims began to be interested in Greek scientific and medical texts for the first time, and had some of Galen 's texts translated into Arabic, often by Syrian Christian scholars ( see below ). As a result, some texts of Galen exist only in Arabic translation, while others exist only in medieval Latin translations of the Arabic. In some cases scholars have even attempted to translate from the Latin or Arabic back into Greek where the original is lost. For some of the ancient sources, such as Herophilus, Galen 's account of their work is all that survives. Even in his own time, forgeries and unscrupulous editions of his work were a problem, prompting him to write On his Own Books. Forgeries in Latin, Arabic or Greek continued until the Renaissance. Some of Galen 's treatises have appeared under many different titles over the years. Sources are often in obscure and difficult - to - access journals or repositories. Although written in Greek, by convention the works are referred to by Latin titles, and often by merely abbreviations of those. No single authoritative collection of his work exists, and controversy remains as to the authenticity of a number of works attributed to Galen. As a consequence, research on Galen 's work is fraught with hazard. Various attempts have been made to classify Galen 's vast output. For instance Coxe ( 1846 ) lists a Prolegomena, or introductory books, followed by 7 classes of treatise embracing Physiology ( 28 vols. ), Hygiene ( 12 ), Aetiology ( 19 ), Semeiotics ( 14 ), Pharmacy ( 10 ), Blood letting ( 4 ) and Therapeutics ( 17 ), in addition to 4 of aphorisms, and spurious works. The most complete compendium of Galen 's writings, surpassing even modern projects like the Corpus Medicorum Graecorum, is the one compiled and translated by Karl Gottlob Kühn of Leipzig between 1821 and 1833. This collection consists of 122 of Galen 's treatises, translated from the original Greek into Latin ( the text is presented in both languages ). Over 20,000 pages in length, it is divided into 22 volumes, with 676 index pages. Many of Galen 's works are included in the Thesaurus Linguae Graecae, a digital library of Greek literature started in 1972. Another useful modern source is the French Bibliothèque interuniversitaire de médecine ( BIUM ). Legacy Late antiquity In his time, Galen 's reputation as both physician and philosopher was legendary, the Emperor Marcus Aurelius describing him as `` Primum sane medicorum esse, philosophorum autem solum '' ( first among doctors and unique among philosophers Praen 14 : 660 ). Other contemporary authors in the Greek world confirm this including Theodotus the Shoemaker, Athenaeus and Alexander of Aphrodisias. The 7th - century poet George of Pisida went so far as to refer to Christ as a second and neglected Galen. Galen continued to exert an important influence over the theory and practice of medicine until the mid-17th century in the Byzantine and Arabic worlds and Europe. Hippocrates and Galen form important landmarks of 600 years of Greek medicine. A.J. Brock describes them as representing the foundation and apex respectively. A few centuries after Galen, Palladius Iatrosophista stated, in his commentary on Hippocrates, that Hippocrates sowed and Galen reaped. Thus Galen summarised and synthesised the work of his predecessors, and it is in Galen 's words ( Galenism ) that Greek medicine was handed down to subsequent generations, such that Galenism became the means by which Greek medicine was known to the world. Often, this was in the form of restating and reinterpreting, such as in Magnus of Nisibis ' 4th - century work on urine, which was in turn translated into Arabic. Yet the full importance of his contributions was not appreciated till long after his death. Galen 's rhetoric and prolificity were so powerful as to convey the impression that there was little left to learn. The term Galenism has subsequently taken on both a positive and pejorative meaning as one that transformed medicine in late antiquity yet so dominated subsequent thinking as to stifle further progress. After the collapse of the Western Empire the study of Galen and other Greek works almost disappeared in the Latin West. In contrast, in the predominantly Greek - speaking eastern half of the Roman empire ( Byzantium ), many commentators of the subsequent centuries, such as Oribasius, physician to the emperor Julian who compiled a Synopsis in the 4th century, preserved and disseminated Galen 's works, making Galenism more accessible. Nutton refers to these authors as the `` medical refrigerators of antiquity ''. In late antiquity, medical writing veered increasingly in the direction of the theoretical at the expense of the practical, with many authors merely debating Galenism. Magnus of Nisibis was a pure theorist, as were John of Alexandria and Agnellus of Ravenna with their lectures on Galen 's De Sectis. So strong was Galenism that other authors such as Hippocrates began to be seen through a Galenic lens, while his opponents became marginalised and other medical sects such as Asclepiadism slowly disappeared. Greek medicine was part of Greek culture, and Syrian Eastern Christians came in contact with it while the Eastern Roman Empire ( Byzantium ) ruled Syria and Western Mesopotamia, regions that were conquered from Byzantium in the 7th century by Arab Muslims. After AD 750, Muslims had these Syrian Christians make the first translations of Galen into Arabic. From then on, Galen and the Greek medical tradition in general became assimilated into the medieval and early modern Islamic Middle East. Influence on medicine in the Islamic world Further information : Medicine in the medieval Islamic world Galen 's approach to medicine became and remains influential in the Islamic world. The first major translator of Galen into Arabic was the Syrian Christian Hunayn ibn Ishaq. He translated ( c. 830 -- 870 ) 129 works of `` Jalinos '' into Arabic. Arabic sources, such as Rhazes ( Muhammad ibn Zakarīya Rāzi AD 865 -- 925 ), continue to be the source of discovery of new or relatively inaccessible Galenic writings. One of Hunayn 's Arabic translations, Kitab ila Aglooqan fi Shifa al Amrad, which is extant in the Library of Ibn Sina Academy of Medieval Medicine & Sciences, is regarded as a masterpiece of Galen 's literary works. A part of the Alexandrian compendium of Galen 's work, this 10th - century manuscript comprises two parts that include details regarding various types of fevers ( Humyat ) and different inflammatory conditions of the body. More important is that it includes details of more than 150 single and compound formulations of both herbal and animal origin. The book provides an insight into understanding the traditions and methods of treatment in the Greek and Roman eras. In addition, this book provides a direct source for the study of more than 150 single and compound drugs used during the Greco - Roman period. As the title of Doubts on Galen by Rhazes implies, as well as the writings of physicians such as Ibn Zuhr ( Avenzoar ) and Ibn al - Nafis, the works of Galen were not accepted unquestioningly, but as a challengeable basis for further inquiry. A strong emphasis on experimentation and empiricism led to new results and new observations, which were contrasted and combined with those of Galen by writers such as Rhazes, Ali ibn Abbas al - Majusi ( Haly Abbas ), Abu al - Qasim al - Zahrawi ( Abulasis ), Ibn Sina ( Avicenna ), Ibn Zuhr and Ibn al - Nafis. For example, the experiments carried out by Rāzi and Ibn Zuhr contradicted the Galenic theory of humorism, while Ibn al - Nafis ' discovery of the pulmonary circulation contradicted the Galenic theory on the heart. The influence of Galen 's writings, including humorism, remains strong in modern Unani medicine, now closely identified with Islamic culture, and widely practiced from India ( where it is officially recognized ) to Morocco. Reintroduction to the Latin West Mondino dei Liuzzi, Anathomia, 1541 From the 11th century onwards, Latin translations of Islamic medical texts began to appear in the West, alongside the Salerno school of thought, and were soon incorporated into the curriculum at the universities of Naples and Montpellier. From that time, Galenism took on a new, unquestioned authority, Galen even being referred to as the `` Medical Pope of the Middle Ages ''. Constantine the African was amongst those who translated both Hippocrates and Galen from Arabic. In addition to the more numerous translations of Arabic texts in this period, there were a few translations of Galenic works directly from the Greek, such as Burgundio of Pisa 's translation of De complexionibus. Galen 's works on anatomy and medicine became the mainstay of the medieval physician 's university curriculum, alongside Ibn Sina 's The Canon of Medicine, which elaborated on Galen 's works. Unlike pagan Rome, Christian Europe did not exercise a universal prohibition of the dissection and autopsy of the human body and such examinations were carried out regularly from at least the 13th century. However, Galen 's influence was so great that when dissections discovered anomalies compared with Galen 's anatomy, the physicians often tried to fit these into the Galenic system. An example of this is Mondino de Liuzzi, who describes rudimentary blood circulation in his writings but still asserts that the left ventricle should contain air. Some cited these changes as proof that human anatomy had changed since the time of Galen. The most important translator of Galen 's works into Latin was Niccolò di Deoprepio da Reggio, who spent several years working on Galen. Niccolò worked at the Angevin Court during the reign of king Robert of Naples. Among Niccolò 's translations is a piece from a medical treatise by Galen, of which the original text is lost. Renaissance Galen 's Opera omnia, dissection of a pig. Venice, 1565 The Renaissance, and the fall of the Byzantine Empire ( 1453 ), were accompanied by an influx of Greek scholars and manuscripts to the West, allowing direct comparison between the Arabic commentaries and the original Greek texts of Galen. This New Learning and the Humanist movement, particularly the work of Linacre, promoted literae humaniores including Galen in the Latin scientific canon, De Naturalibus Facultatibus appearing in London in 1523. Debates on medical science now had two traditions, the more conservative Arabian and the liberal Greek. The more extreme liberal movements began to challenge the role of authority in medicine, as exemplified by Paracelsus ' symbolically burning the works of Avicenna and Galen at his medical school in Basle. Nevertheless, Galen 's pre-eminence amongst the great thinkers of the millennium is exemplified by a 16th - century mural in the refectory of the Great Lavra of Mt Athos. It depicts pagan sages at the foot of the Tree of Jesse, with Galen between the Sibyl and Aristotle. Galen. De pulsibus. ( Manuscript ; Venice, c. 1550 ). This Greek manuscript of Galen 's treatise on the pulse is interleaved with a Latin translation. Galenism 's final defeat came from a combination of the negativism of Paracelsus and the constructivism of the Italian Renaissance anatomists, such as Vesalius in the 16th century. In the 1530s, the Flemish anatomist and physician Andreas Vesalius took on a project to translate many of Galen 's Greek texts into Latin. Vesalius ' most famous work, De humani corporis fabrica, was greatly influenced by Galenic writing and form. Seeking to examine critically Galen 's methods and outlook, Vesalius turned to human cadaver dissection as a means of verification. Galen 's writings were shown by Vesalius to describe details present in monkeys but not in humans, and he demonstrated Galen 's limitations through books and hands - on demonstrations despite fierce opposition from orthodox pro-Galenists such as Jacobus Sylvius. Since Galen states that he is using observations of monkeys ( human dissection was prohibited ) to give an account of what the body looks like, Vesalius could portray himself as using Galen 's approach of description of direct observation to create a record of the exact details of the human body, since he worked in a time when human dissection was allowed. Galen argued that monkey anatomy was close enough to humans for physicians to learn anatomy with monkey dissections and then make observations of similar structures in the wounds of their patients, rather than trying to learn anatomy only from wounds in human patients, as would be done by students trained in the Empiricist model. The examinations of Vesalius also disproved medical theories of Aristotle and Mondino de Liuzzi. One of the best known examples of Vesalius ' overturning of Galenism was his demonstration that the interventricular septum of the heart was not permeable, as Galen had taught ( Nat Fac III xv ). However, this had been revealed two years before by Michael Servetus in his fateful `` Christianismi restitutio '' ( 1553 ) with only three copies of the book surviving, but these remaining hidden for decades ; the rest were burned shortly after its publication because of persecution of Servetus by religious authorities. Michael Servetus, using the name `` Michel de Villeneuve '' during his stay in France, was Vesalius ' fellow student and the best Galenist at the University of Paris, according to Johann Winter von Andernach, who taught both. In the Galenism of the Renaissance, editions of the Opera Omnia by Galen were very important. It was begun in Venice in 1541 -- 1542 by the Guinta. There were fourteen editions of the book from that date until 1625. Just one edition was produced from Lyon between 1548 and 1551. The Lyon edition has commentaries on breathing and blood streaming that correct the work of earlier renowned authors such as Vesalius, Caius or Janus Cornarius. `` Michel De Villeneuve '' had contracts with Jean Frellon for that work, and the Servetus scholar - researcher Francisco Javier González Echeverría presented research that became an accepted communication in the International Society for the History of Medicine, which concluded that Michael De Villeneuve ( Michael Servetus ) is the author of the commentaries of this edition of Frellon, in Lyon. Another convincing case where understanding of the body was extended beyond where Galen had left it came from these demonstrations of the nature of human circulation and the subsequent work of Andrea Cesalpino, Fabricio of Acquapendente and William Harvey. Some Galenic teaching, such as his emphasis on bloodletting as a remedy for many ailments, however, remained influential until well into the 19th century. Contemporary scholarship Galenic scholarship remains an intense and vibrant field, following renewed interest in his work, dating from the German encyclopedia Realencyclopädie der Classischen Altertumswissenschaft. Copies of his works translated by Robert M. Green are held at the National Library of Medicine in Bethesda, Maryland.
