The historical study of Christianity traditionally begins in the eastern Mediterranean and then turns westwards, focusing on the historical and theological development of Christianity in its Greek and Latin contexts. But such an approach paints an extremely partial picture of the development and spread of Christianity in late antiquity and the early medieval period more broadly — one that, for example, completely omits the rich heritage of Christianity in the Syriac tradition. A dialect of Palestinian Aramaic, Syriac was, for several centuries, the preeminent Christian literary language from the Syrian countryside through Mesopotamia to the Iranian plateau. In addition to surveying (in English translation) the unique biblical, theological, liturgical, hagiographical, and historiographical contributions of Syriac-speaking Christians and their literatures from the first centuries of the Common Era up to the early Islamic period, this course will focus on the importance of Syriac and Syriac Christianity as a bridge linking Rome with Persia and Byzantium with Baghdad. As such, some time, too, will be spent examining the history of Christianity in upper Egypt, Ethiopia, and the Arabian Peninsula. This course should thus be of interest to graduate students in a variety of fields, including biblical studies and Christian origins, Christianity in late antiquity, Sasanian/Zoroastrian studies, and early Islam.
