This volume presents an edition of Thomas of Edessa's Syriac text of Nativity and Epiphany, accompanied by a facing-page English translation. These discourses, with the editors' introduction and notes, elucidate Thomas's place in the theological development of the Church of the East. He is the earliest author after Narsai to draw extensively upon the theology of Theodore of Mopsuestia, but earlier Syriac traditions are also reflected in his work, and his Christology is not yet the doctrine characteristic of Babai and later East Syriac authors.
