Innovation in Byzantine Medicine

Byzantine medicine remains a little known and misrepresented field not only in the context of debates on medieval medicine, but also among Byzantinists themselves. It is often viewed as stagnant and mainly preserving ancient ideas, and our knowledge of it continues to be based to a great extent on the comments of earlier authorities, which are often repeated uncritically. This volume presents the first comprehensive examination of the medical corpus of, arguably, the most important Late Byzantine physician:: John Zacharias Aktouarios (c.1275-c.1330). Its main thesis is that Johns medical works show an astonishing degree of openness to knowledge from outside Byzantium combined with a significant degree of originality, in particular, in the fields of uroscopy and human physiology. The analysis of Johns edited (On Urines and OnPsychic Pneuma) and unedited (Medical Epitome) treatises is supported for the first time by the consultation of a large number of manuscripts, and is also informed by evidence from a wide range of medical sources, including those previously unpublished, and texts from other genres, such as epistolography and merchants accounts. Thecontextualization of Johns corpus sheds new light on the development of Byzantine medical thought and practice, and enhances our understanding of the Late Byzantine social and intellectual landscape. Through examination of his medical observations in the light of examples from the medieval Latin and Islamic worlds, his theories are also placed within the wider Mediterranean milieu, highlighting the cultural exchange between Byzantium and its neighbours.
