the theory of humors, along with astrology, governed practice. All human temperaments were considered to belong to one or another of the four humors—sanguine, phlegmatic, choleric, and melancholic. In various permutations with the signs of the zodiac, each of which governed a particular part of the body, the humors and constellations determined the degrees of bodily heat, moisture, and proportion of masculinity and femininity of each person.
