The Hippocratic Epidemics and Galen’s Commentary on them constitute milestones in the development of clinical medicine. But they also illustrate the rich exegetical traditions that existed in the post-classical Greek world. The present volume investigates these texts from various and diverse vantage points: textual criticism; Greek philology; knowledge transfer through translations; and medical history. Especially the Syriac and Arabic traditions of the Epidemics come under scrutiny.
