Heresy and Heretics in the Thirteenth Century: The Textual Representations

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 wandering preachers. In considering the whole scope of anti-heretical writing from this narrow 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 more complex relationship with its subject matter.
