This collection of articles presents cutting-edge scholarship in Hippocratic studies in English from an international range of experts. It pays special attention to the commentary tradition, notably in Syriac and Arabic, and its relevance to the constitution and interpretation of works in the Hippocratic Corpus. It presents new evidence from hitherto unpublished sources, including Greek papyri and Syriac and Arabic manuscripts. It encompasses not only the classical period (and notably Galen), but also tackles evidence from the medieval and Renaissance periods.
