In view of the paucity of other sources for this century, so momentous in the history of the Near East, the Syriac materials take on a particular importance for both Byzantine and Islamic historians. While some of these sources, such as Michael’s Chronicle, are well known to all, others lie as yet unexploited and ignored. The purpose of the present article is to collect together in convenient form details of all the main Syriac sources available for the seventh century, listing standard editions, translations and the more important discussions. Fuller information on authors and secondary literature can readily be found by reference to the following works: A. Baumstark, Geschichte der syrischen Literatur (Bonn, 1922); I. Ortiz de Urbina, Patrologia Syriaca, 2nd ed. (Rome, 1965); C. Moss, Catalogue of Syriac Printed Books and Related Literature in the British Museum (London, 1962); S. P. Brock, ‘Syriac Studies 1960-1970: a classified bibliography’, Parole de l’Orient, IV (1973), 393-465. For the topographical history ot the area now covered by Iraq, J. M. Fiey’s Assyrie chrétienne, 3 vols. (Beirut, 1965-8), is an invaluable compendium.
