Moses Maimonides (1135-1204) wrote many philosophical, legal, and medical works. Of these, Medical Aphorisms is among his best known. Consisting of approximately fifteen hundred maxims from the ancient Greek physician Galen, it is arranged as twenty-five treatises organized according to traditional medieval subspecialties such as gyoecology, hygiene, and diet. Because the source texts no longer survive, Maimonides' version provides vital clues about Galen's thought that would otherwise remain unknown. This critical edition includes both the definitive Arabic text and a masterly English translation.
