Cyriacus of Tagrit was patriarch of the Syrian Orthodox Church of Antioch between 793 and 817 under the Abbasid Caliphate, a turbulent and divided period in the history of his church in the Middle East. This work, for the first time, collects together and provides a critical edition and annotated English translation of all of his extant and accessible writings. The book focuses on his major composition, The Book on Divine Providence.
