Description: The first edition, translation, and commentary on previously unknown medieval sermons written to defend the Catholic religion against heresy in the early thirteenth century, set against the historical backdrop of the crusade against Albigensian heretics in south-western France and during campaigns to push back heresy in northern France.
Review Quotes: "Preaching and crusade researchers will benefit first and foremost from the reliable edition with its profound commentary, but also all those who deal with the political and cultural history of the 13th century." -- Ralf Lützelschwab, Sehepunkte
