und jüdischen Protagonisten, die Auseinandersetzung mit dem Islam in Spanien, die christlichen Mohammedviten und die konfessionelle Gemengelage im spätmittelalterlichen venezianischen Kreta. The Christian-based European realms of the Middle Ages were by no means religiously homogeneous. Contact, cooperation and conflict with other denominations and religions had handled with intellectually and pragmatically. Dialogic texts, which collected arguments meant to secure one's own position and to convince the opposing side, played a central role among the media dealing with other religions. The contributions to this interdisciplinary anthology discuss such imagined religious conversations, as well as references to real discussions on questions of faith, late medieval disputations with representatives of Jewish communities, and everyday conversations between Christians and Jews. Literary and social relationships between Christian and Jewish protagonists, the preoccupation with Islam in Spain, Christian Vitae of Mohammed and the confessional mix in late medieval Venetian Crete are examined
