Sebastian Brock is a leading authority in the field of Syriac studies which he taught for many years in the University of Oxford, where he remains Emeritus (https://www.ames.ox.ac.uk/people/sebastian-p-brock), and Fellow of the British Academy. He is widely recognised for his important work translating Syriac texts, especially those of 4th to 7th centuries, and making better known the mediating role of textual translation in late Antiquity, especially the cultural interface between Syriac and Greek. Among his many publications are The Luminous Eye: The Spiritual World Vision of St Ephrem (1985), The Wisdom of Isaac of Nineveh [Syriac-English] (Piscataway NJ, 2006), A Brief Outline of Syriac Literature (2nd edition 2011); The Bible in the Syriac Tradition (3rd edition 2023); An Inventory of Syriac Texts Published from Manuscripts in the British Library (2020). This lecture will explore the way in which the texts of the 7th century Isaac the Syrian form part of a multi-dimensional Christian heritage.
