Diatessaron is a name for Jesus Christ Gospel according to Tatian the Syrian.

It’s original Syrian title is unknown but later it is called “ܐܘܢܓܠܝܘܢ ܕܡܚܠܛܐ”, or “اونجلیون دمحلطا” means “Gospel of the mixed” ,in opposition to “ܐܘܢܓܠܝܘܢ ܕܡܦܪܫܐ”, or “اونجلیون دمفرشا” means “Gospel of the separated”

Diatessaron is the oldest (Syrian) gospel ever known. Unfortunately the Syriac text of Diatessaron missed and we have just some quotations from it.

Diatessaron had been translated by Abul Faraj ibn Tayyeb from Syrian to Arabic in 11th century that survived for us.

The source for most published English translations are this Arabic translation.

A Persian translation from Syrian also exist.

Fortunately I have received an old version of the Arabic and Latin book published at 1888 in Rome.

This book published at Rome in 1888, in a volume entitled in Arabic Diatessaron, which Titianus Compiled from the Four Gospels,(دیاطاسارون الذی جمعه طظیانوس من المبشرین الاربعه) with the alternative Latin title, Tatiani Evangeliorum Harmonicae, Arabice. The Roman volume consists of two parts-the text, covering a little over 209 very clearly printed Arabic pages, and a Latin half, comprising a scholarly introduction (pp. v.-xv.), a Latin translation (pp. 1-99), and a table showing the order in which the passages taken from the gospels occur in the text. The editor is P. Augustinus Ciasca, a well known Orientalist, “scriptor” at the Vatican Library.

For use of other researcher, here I’m publishing an electronic copy of this book that Published in Rome.

According to different page orders in Arabic and Latin parts of this book, I have divided the book into two parts: The Arabic Part and The Latin Part.
