Tatian's Diatessaron and the Old Testament Peshitta‪.‬

Did Tatian consult the Syriac version of the OT when drawing up his Gospel harmony? This question, first raised almost a century ago, (1) has not become irrelevant since then, in spite of much progress in research on both the Diatessaron and the OT Peshitta. (2) In a study of OT quotations contained in the Old Syriac and Peshitta Gospels, the present writer, following in the footsteps of F. C. Burkitt and S. P. Brock, undertook to show that Tatian did make use of the OT Peshitta. (3) I concluded that Tatian, in his Diatessaron, frequently inserted OT Peshitta readings as a rendering of OT quotations instead of translating the Greek text as read in the Gospels. (4)
