The physician
Galen (130-199 AD) elaborated
a model of health and disease as a
structure of elements, qualities,
humors, organs, and temperaments.
Health was understood in this
perspective to be a condition of
harmony or balance (eucrasia)
among these basic components that
make up both nature in general and
the individual body. Disease was
interpreted as the disproportion (dyscrasia)
of bodily fluids or
four humours: phlegm, blood,
and yellow and black bile.
