Surgery in the Middle Ages

The Middle Ages saw illness as an imbalance in the humors of the body. Sometimes that could be treated by changing the diet. In the case of some illnesses, it might be determined that the body had too much of the "hot, wet" humor, blood, for which the treatment was to drain some of it.

Blood-letting was the simplest surgical procedure, but medieval surgeons were eager to accomplish more. Part of the history of surgery in Western Europe was tied to the needs of warfare. Consider John Bradmore's efforts to remove an arrow from Henry V. Another surgeon connected to royalty was John Arderne, the expert on a very particular and painful physical problem that he treated with surgery.

Monasteries and other religious organizations were more educated than the general population, and their access to books meant knowing more about medicine. There was one branch of medicine they avoided, however, even though the Egyptian and Greeks practiced it: dissection and surgery. The church was squeamish about surgery because it shed blood (and could lead to infection and death). The Fourth Lateran Council of 1215 prohibited clerics from surgery or any practice that shed blood. Dissection of corpses was also frowned on.

Lay people, however, continued to expand knowledge of anatomy. The Italian Cronica of Salimbene di Adam (1221 - c.1290) tells the story of an epidemic that was killing men and chickens. A physician of Cremona discovered through dissection that the chickens had abcesses in their hearts. The corpse of a human victim was dissected; the same abcesses were found. The physician put out a pamphlet warning people against eating chicken or eggs, assuming that they were causing the spread of the disease.

Italy was where great strides in anatomy and surgery took place. The Anatomical Theatre of Padua, begun in 1595, was the first permanent anatomical theater in the world, where students watched their teachers dissect bodies to learn human anatomy. Anatomical dissection in Italy had begun long before that, however. For that story, we have to look at Italian physician Mondino de Luzzi (c.1270 - 1326), and the Anathomia corporis humani of 1316. We'll look into him next time.
