Book excerpt: Christian-Muslim Relations, a Bibliographical History 1 (CMR1) is the first part of a general history of relations between the faiths from the seventh century to the present. It covers the period from 600 to 1500, when encounters took place through the extended Mediterranean basin and are recorded in Syriac, Arabic, Greek, Latin and other languages. It comprises introductory essays on the treatment of Christians in the Qur'an, Qur'an commentaries, biographies of the Prophet, Hadith and Sunni law, and of Muslims in canon law, and the main body of more than two hundred detailed entries on all the works recorded, whether surviving or lost. These entries provide biographical details of the authors where known, descriptions and assessments of the works themselves, and complete accounts of manuscripts, editions, translations and studies. The result of collaboration between leading scholars, CMR1 is intended as a basic tool for research in Christian-Muslim relations.
