Legal and Medical Training

The growth of the University of Bologna coincided with a revival of interest in Roman law during the investiture controversy. The study of Roman law as embodied in the Code of Justinian (see Chapter 7) had never completely died out in the West, but in the late eleventh century a complete manuscript of Justinian’s Code was discovered in a library in Pisa. This discovery led scholars in nearby Bologna, beginning with Irnerius (ehr-NEH-ree-uhs) (ca. 1055–ca. 1130), to study and teach Roman law intently.

Irnerius and other teachers at Bologna taught law as an organic whole related to the society it regulated, an all-inclusive system based on logical principles that could be applied to difficult practical situations. Thus, as social and economic structures changed, law would change with them. Jurists educated at Bologna — and later at other universities — were hired by rulers and city councils to systematize their law codes and write legal treatises. In the 1260s the English jurist Henry Bracton wrote a comprehensive treatise bringing together the laws and customs of England, and King Alfonso X of Castile had scholars write the Siete Partidas (Book in Seven Parts), a detailed plan for administering his whole kingdom according to Roman legal principles.

Canon law (see Chapter 9) was also shaped by the reinvigoration of Roman law, and canon lawyers in ever-greater numbers were hired by church officials or became prominent church officials themselves. In about 1140 the Benedictine monk Gratian put together a collection of nearly 3,800 texts covering all areas of canon law. His collection, known as the Decretum, became the standard text on which teachers of canon law lectured and commented.

Jewish scholars also produced elaborate commentaries on law and religious tradition. Medieval universities were closed to Jews, but in some cities in the eleventh century special rabbinic academies opened that concentrated on the study of the Talmud, a compilation of legal arguments, proverbs, sayings, and folklore that had been produced in the fifth century in Babylon (present-day Iraq). Men seeking to become rabbis — highly respected figures within the Jewish community, with authority over economic and social as well as religious matters — spent long periods of time studying the Talmud, which served as the basis for their decisions affecting all areas of life.

Professional medical training began at Salerno. Individuals there, such as Constantine the African (1020?–1087) — who was a convert from Islam and later a Benedictine monk — began to translate medical works out of Arabic. These translations included writings by the ancient Greek physicians and Muslim medical writers, a blending of knowledge that later occurred on the nearby island of Sicily as well. (See “Evaluating the Evidence 10.2: Healthy Living.”) Students of medicine poured into the city.

Medical studies at Salerno were based on classical ideas, particularly those of Hippocrates and Aristotle (see Chapter 3). For the ancient Greeks, ideas about the human body were very closely linked to philosophy and to ideas about the natural world in general. Prime among these was the notion of the four bodily humors — blood, phlegm, black bile, and yellow bile — fluids in the body that influenced bodily health. Each individual was thought to have a characteristic temperament or complexion determined by the balance of these humors, just as today we might describe a person as having a “positive outlook” or a “type A” personality. Disease was generally regarded as an imbalance of humors, which could be diagnosed by taking a patient’s pulse or examining his or her urine. Treatment was thus an attempt to bring the humors back into balance, which might be accomplished through diet or drugs — mixtures of herbal or mineral substances — or by vomiting, emptying the bowels, or bloodletting. The bodily humors were somewhat gender related — women were regarded as tending toward cold and wet humors and men toward hot and dry — so therapies were also gender distinctive. Men’s greater heat, scholars taught, created other gender differences: heat caused men’s hair to burn internally so that they went bald, and their shoulders and brains to become larger than those of women (because heat rises and causes things to expand).

These ideas spread throughout Europe from Salerno and became the basis of training for physicians at other universities. University training gave physicians high social status and allowed them to charge high fees. They were generally hired directly by patients as needed, though some had more permanent positions as members of the household staffs of especially wealthy nobles or rulers.
