The Gospel of Tatian: Exploring the Nature and Text of the Diatessaron
Moreover, although it was once suggested that the CPA Gospels show influence from Tatian's Diatessaron (Matthew Black, "The Palestinian Syriac Gospels and the Diatesseron," Oriens Christianus 36 [1941]: 101-11), the discovery in 1957, 1984, and 1986 of portions of Chester Beatty MS 709 containing Ephrem's Commentary on the Diatessaron has opened new possibilities for research into the relationship between Syriac and CPA.
In a commentary on Diatessaron, Ephrem said: 'To prevent his disciples from asking the time of his coming, Christ said: 'About that hour no one knows, neither the angels nor the Son.' He has kept those things hidden so that we may keep watch, each of us thinking that He will come in our own day.'
Its origin can be found in the early Christian apologetic period, where Tatian wrote his Diatessaron in c.
a) a estrutura geral do texto (ate o v.21; quica ate o 33), baseada na sequencia pai Zacarias/filho Joao--mae Maria/filho Jesus, repousa num eixo que remete ao Evangelho segundo Lucas, em seus dois primeiros capitulos, com ou sem a mediacao do Diatessaron de Taciano, o que pode ser verificado tambem nos detalhes, nas suposicoes, omissoes e correcoes que a sura parece estabelecer sobre esta tradicao.
These followed the tradition of early Christian Harmonies, the oldest of which was the Diatessaron attributed to Tatian, an author of the second century.
385-88 (v): a brief diatessaron, probably a supply on leaves originally blank.
Among the topics are the papyrus manuscripts, the Greek minuscules, the Greek lectionaries, the Diatessaron of Tatian, the Syriac versions, the Coptic versions, the Ethiopic version, the Armenian version, the Gothic version, the use of the Greek fathers for New Testament textual criticism, scribal tendencies in transmission, analyzing and categorizing New Testament Greek manuscripts, criteria for evaluating readings in textual criticism, modern critical edition and apparatuses of the Greek New Testament, and reasoned eclecticism in New Testament textual criticism.
La empresa de una vida de Jesus concordada no se habia documentado desde el Diatessaron de Taciano; existian, eso si, catenae comentando los evangelios.
Diaphoniam seu organum constat ex diatessaron symphonia naturaliter derivari.
Another unsatisfactory solution was either to settle on one gospel, a la Marcion [an edited Luke], or to try to harmonize the gospels--or Samuel-Kings with Chronicles--into one coherent account (a la Tatian's Diatessaron).
Dobschutz, Christusbilder, 134, suggests that Jesus' letter shows evidence of borrowing from Tatian's concordance, which would therefore date the letter to the third or fourth century since the Diatessaron was the only Gospel text available in Syria at that time.
