The dialogues in which Christian characters are debating with Jews constitute an important aspect of ancient and medieval Christian literature. Though these texts have long been neglected due to negative prejudice, they have recently come into new focus. Modern critical editions and detailed monographs are now available, but we still need a book which would be exclusively devoted to this group of texts, from its origins to the modern period. This volume, based on the proceedings of the conference organized in Paris in December 2011, offers the first general study of these texts. It is centred primarily on the literary, historical and doctrinal aspects of the aduersus Iudaeos dialogues.
