'Did you see a heretic? When? Where? And, who else was there?'. The inquisitor is questioning, and a suspect is replying; a notary is translating from the vernacular into Latin, and writing it down, abbreviating and omitting at will; later there is the reading out of a sentence in public and then, in a few cases, burning. At every stage there is a text: a list of questions, for example, or an inquisitor's how-to-do it manual. The substance and intention of these texts forms the subject of this book. The introduction brings them all together in an historiographical survey of the role of texts in the suppression of heresy, and the volume is crowned by the Quodlibet lecture, in which the doyen of all heresy historians, Alexander Patschovsky, magisterially surveys the political nature of heresy accusations. The contributors include: Mark Pegg, Peter Biller, Caterina Bruschi, James Given, John Arnold, Jessalyn Bird, Anne Hudson, and Alexander Patschovsky.
