The Syriac Text Translated--The eleventh century ms. of Ibn-at-Tayyib, could we reach it, would bring us face to face with the more interesting question of the nature of his Syriac original. The Subscription to the Borgian ms. states, probably copying the statement from its exemplar, that this was a. Syriac ms. in the handwriting of Isa ibn-Ali al Motatabbib, pupil of Honain ibn Ishak. This Honain was a famous Arabic physician and medical writer of Bagdad (d. 873), whose school produced quite a number of translations and translators, among whom Ibn-Ali, supposed to be identical with the Syriac lexicographer of the same name, is known to have had a high place. The Syriac ms., therefore, that Ibn-at-Tayyib translated takes us back to about the year 900. But the Subscription to each of our mss. ¹ states that the work ended is the gospel called Diatessaron, compiled from the four gospels by Titianus; while the Introductory Note to the Borgian ms. adds that this Titianus was a Greek. The next step, therefore, is to inquire whether any traces exist of such a Syriac work, or any statements by which we can check the account just given of it.
