The medical treatises collected under Hippocrates' name are essential sources of information about the practice of medicine in antiquity and about Greek theories concerning the human body. In this seventh volume of the ongoing Loeb edition of the Hippocratic Collection, Wesley Smith presents the first modern English translation of Books 2 and 4-7 of the Epidemics (the other two books are available in the first volume). In the casebooks and notes that make up the seven books called Epidemics--the title originally meant 'visits'--we can watch ancient physicians observing patients, noting and pondering symptoms, evaluating treatments, and developing theories about the body. They appear to be physicians' notebooks from several areas of the Aegean basin. Smith supplements his clear translation with explanatory notes. The other works available in the Loeb Classical Library edition of Hippocrates are the following. Volume I: Ancient Medicine. Airs, Waters, Places. Epidemics 1 and 3. The Oath. Precepts. Nutriment. Volume II: Prognostic. Regimen in Acute Diseases. The Sacred Disease. The Art. Breaths. Law. Decorum. Physician (Ch. 1). Dentition. Volume III: On Wounds in the Head. In the Surgery. On Fractures.
