The question of the reality of Cathars and other heresies is debated in this provocative collection. Cathars have long been regarded as posing the most organised challenge to orthodox Catholicism in the medieval West, even as a "counter-Church" to orthodoxy in southern France and northern Italy. Their beliefs, understood to be inspired by Balkan dualism, are often seen as the most radical among medieval heresies. However, recent work has fiercely challenged this paradigm, arguing instead that "Catharism" is a construct, mis-named and mis-represented by generations of scholars, and its supposedly radical views were a fantastical projection of the fears of orthodox commentators. This volume brings together a wide range of views from some of the most distinguished internationalscholars in the field, in order to address the debate directly while also opening up new areas for research. Focussing on dualism and anti-materialist beliefs in southern France, Italy and the Balkans, it considers a number of crucial issues. These include: what constitutes popular belief; how (and to what extent) societies of the past were based on the persecution of dissidents; and whether heresy can be seen as an invention of orthodoxy. At the same time, the essays shed new light on some key aspects of the political, cultural, religious and economic relationships between the Balkans and more western regions of Europe in the Middle Ages.

Essays considering how information could be used and abused in the service of heresy and inquisition. The collection, curation, and manipulation of knowledge were fundamental to the operation of inquisition. Its coercive power rested on its ability to control information and to produce authoritative discourses from it - a fact not lost on contemporaries, or on later commentators. Understanding that relationship between inquisition and knowledge has been one of the principal drivers of its long historiography. Inquisitors and their historians have always been preoccupied with the process by which information was gathered and recirculated as knowledge. The tenor of that question has changed over time, but we are still asking how knowledge was made and handed down - to them and to us - and how their sense of what was interesting or useful affected their selection. This volume approaches the theme by looking at heresy and inquisition in the Middle Ages, and also at how they were seen in the sixteenth and seventeenth centuries. The contributors consider a wide range of medieval texts, including papal bulls, sermons, polemical treatises and records of interrogations, both increasing our knowledge of medieval heresy and inquisition, and at the same time delineating the twisting of knowledge. This polarity continues in the early modern period, when scholars appeared to advance learning by hunting for medieval manuscripts and publishing them, or ensuring their preservation through copying them; but at the same time, as some of the chapters here show, these were proof texts in the service of Catholic or Protestant polemic. As a whole, the collection provides a clear view of - and invites readers' reflection on - the shading of truth and untruth in medieval and early modern "knowledge" of heresy and inquisition.

Fresh investigations into heresy after 1300, demonstrating its continuing importance and influence. From the Gregorian reforms to the Protestant Reformation, heresies and heretics helped shape the religious, political, and institutional structures of medieval Europe. Within this larger history of religious ferment, the late medieval period presents a particularly dynamic array of heterodox movements, dissident modes of thought, and ecclesiastical responses. Yet recent debates about the nature of heresy in the twelfth and thirteenth centuries have too easily created an impression of the period after 1300 as merely an epilogue to the high medieval story. This volume takes the history of heresy in late medieval Europe (1300-1500) on its own terms. From Paris to Prague and fromnorthern Germany to Italy and even extending as far as Ethiopia, the essays shed new light on a vibrant world of audacious beguines, ardent Joachites, Spiritual Franciscans, innovative mystics, lay prophets, idiosyncratic alchemists, daring magicians, and even rebellious princes locked in battles with the papacy. As befits a collection honoring the pioneering career of Robert E. Lerner, the studies collected here combine close readings of manuscripts andother sources with a grounding in their political, religious and intellectual contexts, to offer fresh insights into heresies and heretics in late medieval Europe.
