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 already 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. Hippocratic medicine remained the basis of medical practice until the eighteenth century of our era, and the Epidemics long served as textbooks as well as historical records. Smith supplements his clear translation with explanatory notes. Wesley D. Smith is Professor of Clasical Studies, University of Pennsylvania.
