Anonymous’ and Stephanus’ commentaries, written in the 12th century AD, are the first surviving commentaries on Aristotle’s Rhetoric. Their study, including the environment in which they were written and the philosophical ideas expressed in them, provides a better understanding of the reception of Aristotle’s Rhetoric in Byzantium, the Byzantine practice of commenting on classical texts, and what can be called “Byzantine philosophy”. For the first time, this book explores the context of production of the commentaries, discusses the identity and features of their authors, and reveals their philosophical and philological significance. In particular, I examine the main topics discussed by Aristotle in the Rhetoric as contributing to persuasion, namely valid and fallacious rhetorical arguments, ethical notions, emotional response and style, and I analyse the commentators’ interpretations of these topics. In this analysis, I focus on highlighting the value of the philosophical views expressed, and on creating a discussion between the Byzantine and the modern interpretations of the treatise. Conclusively, the two commentators need to be considered as independent thinkers, who aimed primarily at integrating the treatise within the Aristotelian philosophical system.

Byzantine philosophy is an almost unexplored field. Being regarded either as mere scholars or as primarily religious thinkers, Byzantine philosophers, for the most part, have not been studied on their own philosophical merit, and their works have hardly been scrutinized as works of philosophy.Thus, although distinguished scholars in the past have tried to reconstruct the intellectual life of the Byzantine period, there is no question that we still lack even the beginnings of a systematic understanding of the philosophy of the Byzantines.Byzantine Philosophy and its Ancient Sources is conceived as a concerted attempt in this direction. It examines the attitude the Byzantines took towards the ancient philosophical tradition and the specific ancient sources which they relied upon to form their theories. But did the Byzantines merelycopy ancient philosophers or interpret them the way they already had been interpreted in late antiquity? Does Byzantine philosophy as a whole lack a distinctive character which differentiates it from the previous periods in the history of philosophy?Eleven scholars, representing different disciplines from philosophy and history to classics and medieval studies, approach these questions by thoroughly investigating particular topics which give us some insight as to the directions in which we should look for possible answers. These topics range,in modern terms, from philosophy of language, theory of knowledge, and logic, to political philosophy, ethics, natural philosophy, and metaphysics. The philosophers whose works our contributors study belong to all periods from the beginnings of Byzantine culture in the fourth century to the demiseof the Byzantine Empire in the fifteenth century.

Western studies tend to view Byzantine philosophy either as a minor offshoot of western European thought, or a handy storehouse for documents and ideas until they are needed. A scholar of philosophy (Aristotle U. of Thessaloniki), Tatakis (1896-1996) finds the view limiting, pointing out that during the Roman period, few Greeks learned Latin but Romans were not considered educated without a founding in Greek, and that Byzantine Christianity has its own trajectory unconcerned with how it deviates from western orthodoxy.

This volume provides the first authoritative study of the creative appropriation of Greek ethics by late antique and Byzantine authors.

George Gemistos Plethon (c. 1360-1454) was a remarkable and influential thinker, active at the time of transition between the Byzantine Middle Ages and the Italian Renaissance. His works cover literary, historical, scientific, but most notably philosophical issues. Plethon is arguably the most important of the Byzantine Platonists and the earliest representative of Platonism in the Renaissance, the movement which generally exercised a huge influence on the development of early modern thought. Thus his treatise on the differences between Plato and Aristotle triggered the Plato-Aristotle controversy of the 15th century, and his ideas impacted on Italian Renaissance thinkers such as Ficino. This book provides a new study of Gemistos’ philosophy. The first part is dedicated to the discussion of his 'public philosophy'. As an important public figure, Gemistos wrote several public speeches concerning the political situation in the Peloponnese as well as funeral orations on deceased members of the ruling Palaiologos family. They contain remarkable Platonic ideas, adjusted to the contemporary late Byzantine situation. In the second, most extensive, part of the book the Platonism of Plethon is presented in a systematic way. It is identical with the so-called philosophia perennis, that is, the rational view of the world common to various places and ages. Throughout Plethon’s writings, it is remarkably coherent in its framework, possesses quite original features, and displays the influence of ancient Middle and Neo-Platonic discussions. Plethon thus turns out to be not just a commentator on an ancient tradition, but an original Platonic thinker in his own right. In the third part the notorious question of the paganism of Gemistos is reconsidered. He is usually taken for a Platonizing polytheist who gathered around himself a kind of heterodox circle. The whole issue is examined in depth again and all the major evidence discussed, with the result that Gemistos seems rat

Science in Byzantium has rarely been systematically explored. A first of its kind, this collection of essays highlights the disciplines, achievements, and contexts of Byzantine science across the eleven centuries of the Byzantine empire. After an introduction on science in Byzantium and the 21st century, and a study of Christianization and the teaching of science in Byzantium, it offers a comprehensive and up-to-date survey of the scientific disciplines cultivated in Byzantium, from the exact to the natural sciences, medicine, polemology, and the occult sciences. The volume showcases the diversity and vivacity of the varied scientific endeavours in the Byzantine world across its long history, and aims to bring the field into broader conversations within Byzantine studies, medieval studies, and history of science.
