worthless, and praises the reasonableness and high antiquity of Christianity. As early as Eusebius, Tatian was praised for his discussions of the antiquity of Moses and of Jewish legislation, and it was because of this chronological section that his Oratio was not generally condemned. His other major work was the Diatessaron, a "harmony" or synthesis of the four New Testament Gospels into a combined narrative of the life of Jesus. Ephrem the Syrian referred to it as the Evangelion da Mehallete ("The Gospel of the Mixed"), and it was practically the only gospel text used in Syria during the 3rd and 4th centuries. In the mid 5th century the Diatessaron was replaced in those Syrian churches that used it by the four original Gospels. Rabbula, Bishop of Edessa, ordered the priests and deacons to see that every church should have a copy of the separate Gospels (Evangelion da Mepharreshe), and Theodoret, Bishop of Cyrus, removed more than two hundred copies of the Diatessaron from the churches in his diocese. The Syriac Sinaitic manuscript of gospels was produced in between AD 411 and 435 as a result of his edict. A number of recensions of the Diatessaron are extant. The earliest, part of the Eastern family of recensions, is preserved in Ephrem's Commentary on Tatian's work, which itself is preserved in two versions: an Armenian translation preserved in two copies, and a copy of Ephrem's original Syriac text from the late 5th/early 6th century, which has been edited by Louis Leloir (Paris, 1966). Other translations include translations made into Arabic, Persian, and Old Georgian. A fragment of a narrative about the Passion found in the ruins of Dura-Europos in 1933 was once thought to have been from the Diatessaron, but more recent scholarly judgement does not connect it directly to Tatian's work. The earliest member of the Western family of recensions is the Latin Codex Fuldensis, written at the request of bishop Victor of Capua in 545 AD. Although the text is clearly dependent on the Vulgate, the order of the passages is distinctly how Tatian arranged them. Tatian's influence can be detected much earlier in such Latin manuscripts as the Old Latin translation of the Bible, in Novatian's surviving writings, and in the Roman Antiphony. After the Codex Fuldensis, it would appear that members of the Western family led an underground existence, popping into view over the centuries in an
