The Roman History · Amm. 19.4.2

Both philosophers and skilful physicians agree that excess of cold, or of heat, or of moisture, or of drought, all cause pestilences; on which account those who dwell in marshy or wet districts are subject to coughs and complaints in the eyes, and other similar maladies: on the other hand, those who dwell in hot climates are liable to fevers and inflammations. But since fire is the most powerful of all elements, so drought is the quickest at killing.
