This volume, in honour of Professor Elena Lourie, focuses on various areas of interaction between Jews, Muslims and Christians in the late medieval Crown of Aragon and its environs. The articles deal with topics such as war, military campaigns, government, politics, and economics, relations between scholars of the different faiths and their sources, sexual relations and the politics of conversion, mythology and music. Other articles touch on issues such as vassalage, mercenaries, fiscal politics, communal politics and the inquisition. This book presents a mosaic of studies written by three generations of scholars who, using a broad variety of sources and methodologies, examine areas of great interest to Elena Lourie.
