caption_attribution_description: English: Justin the Philosopher
context_page_description: The Diatessaron is the most prominent early gospel harmony, and was created by Tatian, an Assyrian early Christian apologist and ascetic. Tatian sought to combine all the textual material he found in the four gospels—Matthew, Mark, Luke, and John—into a single coherent narrative of Jesus's life and death. However, and in contradistinction to most later gospel harmonists, Tatian appears not to have been motivated by any aspiration to validate the four separate canonical gospel accounts; or to demonstrate that, as they stood, they could each be shown as being without inconsistency or error.
  Although widely used by early Syriac Christians, the original text has not survived, but was reconstructed in 1881 by Theodor Zahn from translations and commentaries.
context_section_description: Tatian was an Assyrian who was a pupil of Justin Martyr in Rome, where, Justin says, the apomnemoneumata (recollections or memoirs) of the Apostles, the gospels, were read every Sunday. When Justin quotes the synoptic Gospels, he tends to do so in a harmonised form, and Helmut Koester and others conclude that Justin must have possessed a Greek harmony text of Matthew, Luke and Mark.
  If so, it is unclear how much Tatian may have borrowed from this previous author in determining his own narrative sequence of Gospel elements. It is equally unclear whether Tatian took the Syriac Gospel texts composited into his Diatessaron from a previous translation, or whether the translation was his own. Where the Diatessaron records Gospel quotations from the Jewish Scriptures, the text appears to agree with that found in the Syriac Peshitta Old Testament rather than that found in the Greek Septuagint—as used by the original Gospel authors. The majority consensus is that the Peshitta Old Testament preceded the Diatessaron, and represents an independent translation from the Hebrew Bible. Resolution of these scholarly questions remained very difficult so long as no complete version of the Diatessaron in Syriac or Greek had been recovered; while the medieval translations that had survived—in Arabic and Latin—both relied on texts that had been heavily corrected to conform better with later canonical versions of the separate Gospel texts.
  There is scholarly uncertainty about what language Tatian used for its original composition, whether Syriac or Greek.
