names; some diseases were called by the name of more than one saint, just
as some saints took care of more than one disease.
Sometimes, the sick were brought to the shrines of either local saints or
the saint thought most likely to help. Relics from the shrines could also be
brought to the sick. The original relics were fragments of bone from the
saint in question; the skeleton of Saint Margaret was held by the queens of
France and was brought into the room in its reliquary when a queen was
due to give birth to a baby. Relics could also be derivative, such as dust
from around a tomb or cloth that had been held in the presence of the
relics. There were also saints’ medals. A medal of Saint Benedict, founder
of the monasteries, had great healing power in the eyes of medieval peo-
ple, since he was the patron saint of all disease.
Prayers to the saints, or special charms invoking saints’ names, were part
of other remedies. A physician might prescribe a remedy like theriac or gin-
ger, but it had to be taken with certain blessings or prayers. Saints could
work through herbal or spice medicines, but it was dangerous to proceed
without any prayer to the saints at all.
Medical Theory
Medieval medicine was based on Aristotle’s idea, also endorsed by Galen,
that there were four humors, or temperaments, in a body. These humors
were expressed in both mind and body, in both personality and health. An
imbalance in humor resulted in disease. Aristotle also divided the world
into four elements: air, fi re, earth, and water. There were also four qualities
of things: hot, cold, dry, and wet. Air was considered hot and wet, while fi re
was hot and dry, earth was cold and dry, and water was cold and wet. The
four humors of the body were based on the same system.
The four humors were liquids thought to exist in the body: blood,
phlegm, yellow bile, and black bile. A temperament majoring in blood
was called sanguine and was hot and wet like air. A body producing more
phlegm was phlegmatic, and it was cold and wet like water. Yellow bile was
warm and dry like fi re, and its temperament was choleric. Black bile was
cold and dry, like earth, and its temperament was melancholic. If the body
produced too much black bile, the result would be a gloomy personality,
along with a physical tendency to coolness and dryness.
Imbalance led to disease. The imbalance might come from diet or bad
air. It might come from bad habits of living. The physician’s job was to ex-
amine the patient, determine the patient’s basic body temperament, and
decide what had gone out of balance. Measles, for example, was a hot, dry
disorder because it involved a high fever. Other illnesses might be hot and
wet or cool and dry. Diet, medicine, and other practical remedies were pre-
scribed to regain the proper balance. The system was not factually correct,
