'Speculum Sermonis', an interdisciplinary anthology of essays about medieval sermons in the Christian world-East as well as West-aims to reveal precisely how sermons inform different disciplines (for instance, social history, literature, liturgiology) and how the methodologies of different disciplines inform sermons. The volume includes an introduction defending the interdisciplinary study of sermons, essays by medievalists from a variety of fields, response papers to the essays in each of the sections, and an authoritative bibliography covering both primary and secondary resources for medieval sermons. The title image of the mirror and reference to medieval specula convey the idea of multiple reflections: the sermons' on culture and the disciplines' on sermons.
