The Diatessaron (c 150 - 160 C.E.) (meaning "Harmony of Four") is an early Christian text written by the apologist and ascetic Tatian, who combined the four canonical gospels into a single harmonious narrative. Tatian attempted to resolve some of the contradictions found in the mainstream gospels by integrating them into one story and removing any duplicate information. For example, he omitted the conflicting genealogies of Matthew and Luke thereby creating a streamlined narrative sequence, which, however, was different from both the synoptic gospels and the Gospel of John. Tation's harmony also does not include Jesus' encounter with the adulteress (John 7:53 - 8:11).
Only fifty-six verses in the canonical Gospels do not have a counterpart in the Diatessaron, mostly the genealogies and the pericope adulterae. The final work is about 72 percent the length of the four gospels put together. He followed the gospels closely in terms of wording but put the verses in a new, different sequence.
In the early church, the gospels at first circulated independently, with Matthew being the most popular. The Diatesseron is notable evidence for the authority already enjoyed by the four gospels by the mid-second century. Twenty years after Tatian's harmony, Irenaeus expressly proclaimed the authoritative character of the four gospels. The Diatesseron became the standard text of the gospels in the Syriac-speaking churches down to the fifth century, when it gave way to the four separate Gospels, in the Peshitta version.
Tatian's Harmonizing of the Gospels
Tatian was an Assyrian pupil of Justin Martyr in Rome. When Justin quoted the Gospels, he tended to do so in a harmonized form, and it is generally concluded that he must have possessed a Greek harmony text; but 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 remain very difficult so long as no complete version of the Diatessaron in Syriac or Greek has been recovered; while the medieval translations that have survived—in Arabic and Latin—both relied on texts that had been heavily corrected to conform better with later canonic versions of the separate Gospel texts.
There has even been disagreement about what language Tatian used for its original composition, whether Syriac or Greek. Modern scholarship tends to favour a Syriac origin; but even so, the exercise must have been repeated in Greek very shortly afterwards—probably by Tatian himself.
Diatessaron in Syriac Christianity
The Diatessaron was used as the standard Gospel text in the liturgy of the Syrian Church for two centuries and was quoted or alluded to by Syrian writers. Ephrem the Syrian wrote a commentary on it, the Syriac original of which was rediscovered only in 1957, when a manuscript acquired by Sir Chester Beatty from the Coptic monastery of Deir es-Suriani in Wadi Natrun, Egypt (now Chester Beatty Syriac MS 709, Dublin) turned out to contain the text of Ephrem's commentary. The incomplete manuscript has been supplemented by stray folios that have appeared on the European market, so that now approximately eighty per cent of the Syriac original is available (McCarthy 1994); for those phrases that Ephrem quotes (which is not the entire text), it provides for the first time, a dependable witness to Tatian's original; and also confirms their content and sequence.
How the Gospel text that was the standard in Syriac Christianity for two centuries should have utterly disappeared requires explaining. Theodoret, bishop of Cyrrhus on the Euphrates in upper Syria in 423, suspecting Tatian having been a heretic, sought out and found more than two hundred copies of the Diatessaron, which he collected and put away, and introduced instead of them the Gospels of the four evangelists. Thus the harmonization was replaced in the fifth century by the canonical four gospels in the Peshitta version, whose Syriac text nevertheless contains many Diatessaronic readings. Gradually, without extant copies to which to refer, the Diatessaron developed a reputation for having been heretical.
Vernacular harmonies derived from the Diatessaron
No Christian tradition, other than the Syriac, has ever adopted a harmonized Gospel text for use in its liturgy. However, in many traditions (given the inherent tendency of Christian liturgical texts to ossification), it was not unusual for subsequent Christian generations to seek to provide paraphrased Gospel versions in language closer to the vernacular of their own day. Frequently such versions have been constructed as Gospel harmonies, sometimes taking the Tatian's Diatessaron as an exemplar; other times proceeding independently. Hence from the Syriac Diatessaron text was derived an eleventh century Arabic harmony (the source for the published versions of the Diatessaron in English); and a thirteenth Century Persian harmony. The Arabic harmony preserves Tatian's sequence exactly, but uses a source text corrected in most places to that of the standard Syriac Peshitta Gospels; the Persian harmony differs greatly in sequence, but translates a Syriac text that is rather closer to that in Ephrem's commentary. The Diatessaron is thought to have been available to Muhammad, and may have led to the assumption in the Quran that the Christian Gospel is one text.
An Old Latin version of Tatian's Syriac text appears to have circulated in the West from the late second century; with a sequence adjusted to conform more closely to that of the canonical Gospel of Luke, and also including additional material (such as the pericope of the adulteress), possibly from the Gospel of the Hebrews. With the gradual adoption of the Vulgate as the liturgical Gospel text of the Latin Church, the Latin Diatessaron was increasingly modified to conform to Vulgate readings. In 546, Victor of Capua discovered such a mixed manuscript; and, further corrected by Victor so as to provide a very pure Vulgate text within a modified Diatessaron sequence, this harmony, the Codex Fuldensis, survives in the monastic library at Fulda, where it served as the source text for vernacular harmonies in Old High German, Eastern Frankish and Old Saxon (the alliterative poem 'Heliand'). The older mixed Vulgate/Diatessaron text type also appears to have continued as a distinct tradition, as such texts appear to underly surviving thirteenth-fourteenth century Gospel harmonies in Middle Dutch, Middle High German, Middle French, Middle English, Tuscan and Venetian; although no example of this hypothetical Latin sub-text has ever been identified. This Latin Diatessaron textual tradition has also been suggested as underlying the enigmatic sixteenth century pro-Muslim Gospel of Barnabas.
Tradition of Gospel harmonies
The name 'Diatessaron' is Greek for 'through four'; the Syriac name for this gospel harmony is 'Ewangeliyôn Damhalltê' ('Gospel of the Mixed'). Indeed, the Syrian Church also rejected John's Book of Revelation and the Pastoral Epistles. They were included again only in the middle of the sixth century.
In the tradition of Gospel harmonies, there is another Diatessaron, reportedly written by one Ammonius the Alexandrian, to correct perceived deficencies in Tatian's. (Note that this Ammonius may or may not be the Ammonius Saccas who taught Origen and Plotinus). None of this revised Diatessaron survives, except as it may have influenced the medieval Arabic and Latin texts that were formerly the only existing reflections of Tatian's work.
Gospel harmonies are valuable in studies of biblical texts, since they frequently offer glimpses of earlier versions of texts. In particular, due to their not having been copied as frequently as biblical texts, more of the earlier versions survive (as newer copies did not exist to replace them). As such, the extant texts contain within them portions of earlier versions of the gospels than the earliest separate gospels known.
In addition, because the Old Testament quotations in the Diatessaron are separately translated from the Hebrew—and hence independent of the Septuagint—these quotations form an important early witness to the vocalization of the Hebrew Bible.
The Qur'an, in referring to Christians and Christian scripture, only makes reference to one gospel. From this it has been inferred that the Arabian Christians of the seventh century were habitually using a harmonization such as the Diatessaron as their principal scripture.
