This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.
A temperament entry records one of the four Galenic humoral types, choleric, melancholic, phlegmatic and sanguine, a documented medical theory of the body attributed to the physician Galen that assigns each temperament a governing bodily fluid, yellow bile, black bile, phlegm and blood, and a paired hot, cold, wet or dry complexion, long before any astrological reading was layered onto that original medical scheme.
An entry records a temperament's documented governing humor and its complexion within Galen's own medical framework first, since the humoral theory itself is a documented ancient theory of physiology and disposition that predates and stands independent of its later astrological use, and only then records the specific planet later astrological tradition pairs with it.
An entry keeps this ancient medical theory honestly distinct from any claim of modern clinical validity, since Galenic humoral medicine is a documented historical system of thought, influential for many centuries, not a theory current medicine accepts, and an entry that presented it as settled fact rather than as a historical intellectual tradition would misstate what kind of claim it actually is.
An entry also records the season Galenic tradition pairs with a temperament, since the medical scheme itself already linked each humor to a time of year before any astrological planet was added to that pairing.
