📖 Key Terms You Must Know

Heresy

A belief that contradicts the official teaching of the Christian Church. In the medieval period, being accused of heresy was extremely serious — it could lead to imprisonment, torture, or execution. Because the Church taught that Galen's work confirmed God's design of the human body, any doctor who challenged Galen's findings could be accused of questioning God's design — and therefore of heresy. This is why Galen's errors survived uncorrected for so long: the institutional threat made challenge impossible for any individual.

Dissection

The cutting open and examination of a human or animal body to study its anatomy. The Church banned human dissection in the medieval period because the body was considered sacred and needed to be preserved intact for resurrection. This ban was the most damaging restriction on medical progress: it prevented Galen's anatomical errors from being discovered and corrected. The ban began to be relaxed in the 14th and 15th centuries, and Vesalius exploited the opportunity in the 1540s to identify over 200 errors in Galen.

Hospice (medieval hospital)

A Church-run institution providing shelter, food, warmth, and basic care for the sick, poor, and pilgrims. Medieval hospices were not hospitals in the modern sense — they rarely provided medical treatment. Their value lay in nursing care: patients who were warm, fed, and rested had better survival rates than those who were sick at home. The Church operated these institutions as a religious duty ("caring for the least of my brothers"), not as a medical service.

Monastic scriptoria

Writing rooms in monasteries where monks copied manuscripts by hand. In the centuries after the fall of the Roman Empire, monastic scriptoria preserved Galen's medical works, Hippocrates' writings, and other classical texts. Without this copying work, the medical knowledge of ancient Greece and Rome would have been entirely lost. This is the Church's clearest positive contribution to the history of medicine.

Dogma

A principle or set of principles laid down by an authority as incontrovertibly true, which must be accepted without question. In medicine, Galen's work became Church dogma — not just a respected authority, but an unchallengeable truth. The transformation of Galen from "respected ancient physician" to "Church-endorsed medical dogma" is the key process that explains why medieval medicine could not progress. Dogma, by definition, cannot be revised in response to evidence.
