This volume consists of eleven essays on medieval romance. It argues as a whole that the romance genre is one of the most important sites for medieval thinking about topics that were elsewhere unthinkable, including things taken for granted, threatening to the status quo, and actively repressed. The essays focus mainly on Old French, Anglo-Norman, and Middle English romances, and they are organized to highlight: the nature of romance thinking, through wonders and ‘unthinking’; what romance thinks, whether kinship or crusades; romance’s relationship with other genres and forms, including historiography, biblical exegesis, and music; and the usefulness of the generic term romance.
