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.

The first book to deal with all the principal treatments of heresy and anti-heretical writings during their heyday in the thirteenth century. Heresy is always relative; the traces that it leaves to us are distorted and one-sided. In the last few decades, historians have responded to these problems by developing increasingly sophisticated methodologies that help to unravel and illuminate the tangled layers from which the texts that describe heresy are built, but in the process have made our reading of heresy fractured and disconnected. Heresy and Heretics seeks to redress this by reading the different types of anti-heretical writing as part of a wider, connected tradition, considering all the principal orthodox treatments of heresy for the first time. Drawn from the mid-thirteenth century, a time when both medieval heresy and the church's response to it were at their zenith, they describe a spectrum of material that ranges from the theological arguments of some of the greatest thinkers of the age to the homely sermons of the wanderingpreachers. In considering the whole scope of anti-heretical writing from this period, it becomes apparent that, far from being an artificial construct isolated from reality, the church's treatment of heresy in fact had a far morecomplex relationship with its subject matter.
