Note 84 — SECTION III.

Hippocrates was of opinion that physicians ought to be skilled in astronomy. And Galen derides those physicians who deny that astronomy is necessary to their art. See his treatise entitled Si quis sit Medicus eundem esse philosophum. And in lib. viii. cap. 20, of his treatise De Ingenio Sanitatis, he calls physicians that are ignorant of astronomy homicides. But by astronomy here, both Hippocrates and Galen intended to signify what is now called astrology. Roger Bacon also, in his Epistle to Pope Clement, says, “Opera quæ fiunt hic inferius, variantur secundum diversitatem cœlestium constellationum, ut opera medicinæ et alkimiæ.” i. e. “The works which are performed in these inferior realms are varied according to the diversity of the celestial constellations, as, for instance, the works of medicine and alchemy.” If, however, as Galen says, and doubtless with great truth, physicians that are ignorant of this are homicides, how numerous must the medical homicides be of the present age!
