Medieval Healthy Living
Humor Theory and its Applications
Ms. Agnes deLanvallei
Humor theory was developed in Roman or pre-Roman times. All things were determined to be composed of the four elements, water, fire, earth, and air. After the fall of Rome the theory was known vaguely to the men of the Catholic Church who preserved knowledge, but was not important them. The theory was preserved and studied among the Arabs.Writings in Arabic were translated into Latin in Spain and made their way to Italy and France from there. As European conditions started to favor the accumulation and development of knowledge, humor theory was part of it. By the end of the MiddleAges, it had been developed into a complex and elaborate set of beliefs, capable of explaining almost everything.1
The problem was that humor/four element theory was not correct. All things turn out to be made of subatomic particles combined into atoms, forming over 100 elements. They aren't made of water, fire, earth, and air. As modern physics and chemistry advanced, more and more of the tenets underlying the four elements and the humor theory of medicine that followed from them were shown to be false. The whole thing was eventually abandoned.
Throughout the Middle Ages, however, the four elements and humors underlaid all scientific explanations
Thus, to live a healthy life almost anywhere in Medieval Europe your physician would urge you to balance your humors. Here I explain about that and try to provide the tools to do so.
Four elements: combine in ALL things.

The seasons and the cardinal directions each are associated with a particular element.
A person, aging, goes from being very moist and hot in infancy, through being hot but dry as a youth, dry and cold in adulthood and moist and cold in old age.
Health is generally a balance of humors.1 The humors are based on the real fluids (blood, bile, phlegm) but they add medical meaning and so an "excess of phlegm" as described by a Medieval physician might not actually require that real phlegm (mucus) be present. Black bile is not a real fluid, but rather one created to balance the system. Everyone should have all four humors, in balanced amounts, to be healthy. Medical treatment favors helping restore balance by adding missing humors or reducing excesses (hence, for example, bleeding as a treatment).
Temperament. Like everything else, people's physiology and psychology are determined by the elements. A trained physician can recognize the different types, which tells them which characteristics are in excess and need treatment.
This figure encapsulates the general view. Note that the year and one's life progress clockwise from air.
AIR WATER FIRE moist (wet) hot

Medical Advice Based on Humor Theory: People were comprised of the four humors: blood, yellow bile, black bile and phlegm. The excess or shortage of one of the humors represented an excess or shortage of one or two of the four elements.
Health is balance: not too much or too little of any one humor. Often Doctrine of Opposites was the prescribed method, correcting an imbalance with its opposite.
Simple Advice that follows from this is:
In summer (hot & dry): take cool wet things
If old (cold & moist): seek hot dry things
In the west (cold & dry):seek hot wet things
If you are sanguine of temperament (hot & moist), avoid hot moist things, seek cool, dry ones.
Specific diseases are imbalances of humors and are treated with the opposites.
The Zodiac/horoscope makes this system even more complex, using twelve, not four points. Expanding along with humor theory, the Zodiac provides more detail, its twelve signs fitting neatly into the scheme drawn above. In the 16th and 17th centuries, well-defined horoscopes allowed the field of medical astrology to develop, in which the person's horoscope was drawn to find which illnesses the time and place of their birth made them prone to.
TYPES OF PEOPLE UNDER HUMOR THEORY
The theory was applied to people, using their physiology to categorize them (see chart above).
Lists of the characteristics are compiled: temperament list.
I apply this to myself: Example
A compilation of the humor characteristics ascribed to a variety of foods and other common things are given: by element; alphabetically
WHAT TO DO WITH THIS IN THE SCA?
Work out your Temperament and the foods your learned physician says you should and should not eat.
Cook feasts that are "healthy" according to Humor Theory.
Amuse yourself and your friends by describing foods or feasts in terms of Humor Theory.
