Does this validate Vitruvius.
“Those who live near the equator, and are exactly under the sun’s course, are, owing to its power, low in stature, of dark complexion, with curling hair, black eyes, weak legs, deficient in quantity of blood. And this deficiency of blood makes them timid when opposed in battle, but they bear excessive heat and fevers without fear, because their limbs are nourished by heat. Those, however, born in northern countries are timid and weak when attacked by fever, but from their sanguineous habit of body more courageous in battle.”
Quite possibly.
I recently read a lot of WW2 N. Africa history.
Patton had little good to say about the natives.
