This is the ninth volume in the Loeb Classical Library's ongoing edition of Hippocrates' invaluable texts, which provide essential information about the practice of medicine in antiquity and about Greek theories concerning the human body. Here Paul Potter presents the Greek text with facing English translation of eleven treatises, four previously unavailable in English, that illuminate Hippocratic medicine in such areas as anatomy, physiology, prognosis and clinical signs, obstetrics, and ophthalmology.
