The Foreword by Professor Jason BeDuhn (Professor of Religious Studies, Northern Arizona University) offers an overview of this book’s critical historiography of the life of Mani, based in part on scepticism regarding the previously known sources, and in part on newly available sources. In introducing this book’s approach, BeDuhn follows various depictions of Mani the 'Apostle of Jesus Christ', the 'Doctor from Babylon', the 'Illuminator' and the 'Great Interpreter' within both the Manichaean tradition and in polemical accounts.
