The collection of Hebrew, Arabic and Jewish manuscript material that was deposited in the Cairo Genizah as early as a thousand years ago is of major significance for our understanding of all aspects of life in the medieval Mediterranean world. This volume presents a selection of papers from the third congress of the Society for Judaeo-Arabic Studies: after introductory material by the editors, it ranges over a wide area of Judaeo-Arabic language and literature, giving the reader a clear impression of recent research in the field. Among the topics covered are the early grammarians, translators and commentators; newly discovered texts of poetry, liturgy and legend; and the religious differences between Jews, Muslims and Christians. The various activities of the Maimonides family naturally attract attention; there are studies of contemporary medicine and magic; and an explanation is offered of Jewish trilingualism. As well as presenting the most recent research in this area, the essays offer a unique insight into the medieval symbiosis of Jewish and Arabic culture. They will be of interest not only to scholars in these areas, but also to those interested in medieval history and philosophy, oriental folklore and medicine.
