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 John's 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 John's edited (On Urines and On Psychic 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of manuscripts, and is also informed by evidence from a wide range of medical sources, including those previously unpublished, and texts from other genres, such as epistolography and merchants' accounts. The contextualization of John's 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.

Scholars have made conflicting claims for Byzantine hospitals as medical institutions and as the forebears of the modern hospital. In this study is the first systematic examination of the evidence of the xenôn texts, or Xenonika, on which all such claims must in part rest. These texts, compiled broadly between the ninth and thirteenth centuries, are also transcribed or edited, with the exception of the combined texts of Romanos and Theophilos that, the study proposes, were originally a single manual and teaching work for doctors, probably based on xenôn practice. A schema of their combined chapter headings sets out the unified structure of this text. A short handlist briefly describes the principal manuscripts referred to throughout the study. The introduction briefly examines our evidence for the xenônes from the early centuries of the East Roman Empire to the fall of Constantinople in 1453. Chapter 3 examines the texts in xenon medical practice and compares them to some other medical manuals and remedy texts of the Late period and to their structures. The xenôn-ascribed texts are discussed one by one in chapters 4–8; the concluding chapter 9 draw together the common, as well as the divergent, aspects of each text and looks to the comparative evidence for hospital medical practice of the time in the West.

This interdisciplinary handbook provides extensive information about research in medieval studies and its most important results over the last decades. The handbook is a reference work which enables the readers to quickly and purposely gain insight into the important research discussions and to inform themselves about the current status of research in the field. The handbook consists of four parts. The first, large section offers articles on all of the main disciplines and discussions of the field. The second section presents articles on the key concepts of modern medieval studies and the debates therein. The third section is a lexicon of the most important text genres of the Middle Ages. The fourth section provides an international bio-bibliographical lexicon of the most prominent medievalists in all disciplines. A comprehensive bibliography rounds off the compendium. The result is a reference work which exhaustively documents the current status of research in medieval studies and brings the disciplines and experts of the field together.
