Judaism, Christianity and Islam - the three scriptural monotheisms, still often studied separately - are here intertwined within a historical frame. The approach outlined in this lecture pivots around the Qur'an as it emerged in seventh-century Arabia on the peripheries of the two world-empires of Iran and Rome, and variously refracts rabbinic Judaism and patristic - especially Syriac - Christianity. The formation and exegesis of scriptural canons helps define the major religious communities and identities both before and after Muhammad. The latter part of the lecture concentrates on the interaction of these communities, and especially their scholars, in the Abbasid Baghdad of the ninth and tenth centuries, and on the theological and philosophical debates that flourished there. The lecture interrogates the newly fashionable concept of 'Abrahamic' religion and proposes a fresh historical periodization inclusive of both late antiquity and Islam, namely the First Millennium.
