The Friar and the Philosopher William of Moerbeke was a prolific medieval translator of Aristotle and other ancient philosophical and scientific authors from Greek into Latin, and he played a decisive role in the acceptance of Aristotelian philosophy in the Latin world. He is often criticized for an allegedly deficient translation method. However, this book argues that his approach was a deliberate attempt to allow readers to reach the correct understanding of the source texts in accord- ance with the medieval view of the role of the translator. William’s project to make all genuine works of Aristotle – and also of other important authors from Antiquity – available in Latin is framed against the background of intel- lectual life in the 13th century, the deliberate policy of his Dominican order to reconcile Christian doctrine with worldly knowledge, and new trends in book production that influenced the spread of the new translations. William of Moerbeke’s seemingly modest acts of translation started an intellectual revolution, the impact of which extended from the Middle Ages into the early modern era. The Friar and the Philosopher will appeal to researchers and students alike interested in Medieval perceptions of Aristotle as well as other works from Antiquity. Pieter Beullens (b. 1967) studied classics and philosophy at the universities of Antwerp and Leuven (Belgium). He published the critical edition of Aristotle’s History of Animals in the Latin translation by William of Moerbeke (with Fernand Bossier, two volumes, 2000–2020). His PhD research centred on the working methods of late medieval translators (A Methodological Approach to Anonymously Transmitted Medieval Translations of Philosophical and Scientific Texts: The Case of Bartholomew of Messina; KU Leuven, 2020). He currently works as a postdoctoral research fellow of the Research Foundation – Flanders at the KU Leuven (2021–2024).

After the greatness of classical Antiquity came the darkness of the medieval period, during which the achievements of earlier times remained hidden and unstudied, until the humanists of the Renaissance rediscovered the treasures of ancient scholarship. Generalisations are misrepresentations. Broad strokes cover up finer lines. Throughout the millennium that is traditionally called the Middle Ages, the association with Antiquity was appreciated and maintained. Especially the link with Roman times was felt vividly present, and the linguistic background stayed unchanged. Latin still was the language of knowledge and research, and education could be achieved only through the study of Latin authors. The tie with Greek science and philosophy was more problematic. Expertise in that field was highly prized yet difficult to attain because of the language barrier. For many centuries, few Greek texts, apart from those translated in Antiquity or assimilated by Roman writers, reached the readers in western Europe. That situation changed significantly in the 12th and 13th centuries. In quick succession, many previously unknown texts with a Greek background arrived in the form of Latin translations through various channels. Their contents produced important shifts in the way of thinking among philoso- phers and students of science and medicine, enough for modern scholars to describe these centuries as early forms of ‘renaissance.’ Research and literature about the great thinkers of the period are abun- dantly available. The same cannot be said about the learned men who trig- gered this significant evolution, the translators who mastered enough Greek to reveal the authoritative writings of the ancient philosophers and scientists to the Latin world. Most overviews of intellectual history name a few among them and stress the importance of their activity without further detail. However, these translators’ decisions regarding the selection and interpreta- tion of texts determined which source material other thinkers and scholars could use. In that manner, they guided the course of important intellectual changes in the later Middle Ages, which merged into the humanist movement of the Renaissance with far less dramatical shifts than is traditionally thought. Preface ix This book aims to do justice to the efforts of the medieval translators. The centre of attention lies with William of Moerbeke, arguably the most influen- tial translator of his time. His work is well studied, but most scholarship cir- culates in various foreign languages. As an unfortunate result, English publications often rely on inaccurate and outdated secondary sources. It is this book’s ambition to provide an accessible introduction to the topic for the general and the academic reader while bringing an up-to-date account of current scholarship and recent publications. Over the years, many people have contributed to my personal development and to my growing understanding of medieval translators, in particular William of Moerbeke. Many names are recorded in this book, others were on my mind as inspirations for its lines of thought. I am especially grateful to Jenny van de Laar and John van Gortel (Damon Publishers, Eindhoven) for their belief in the initial Dutch version of this book and for their willingness to publish it. Piet Gerbrandy (University of Amsterdam) kindly supported the project and wrote a foreword. Without their backing, the English version would probably not exist. The same gratitude goes to editor Michael Greenwood and to the press’s reviewers for accepting the book in this series.
