involved in confusion."(1) We have seen that in the sixth century it was described by Victor of Capua as Diapente, "by five," instead of "by four." It was also confounded with another Harmony written, not long after Tatian's day, by Ammonius of Alexandria (+243). Dionysius Bar-Salibi,(2) a writer of the latter half of the twelfth century, mentions that the Syrian Ephrem, about the middle of the fourth century, wrote a commentary on the Diatessaron of Tatian, which Diatessaron commenced with the opening words of the fourth Gospel: "In the beginning was the word." The statement of Bar-Salibi, however, is contradicted by Gregory Bar-Hebraeus, Bishop of Tagrit, who says that Ephrem Syrus wrote his Commentary on the Diatessaron of Ammonius, and that this Diatessaron commenced with the words of the fourth Gospel: "In the beginning was the word."(3) The Syrian Ebed-Jesu (+l308) held Tatian and Ammonius to be one and the same person; and it is probable that Dionysius mistook the Harmony of Ammonius for that of Tatian. It is not necessary further to follow this discussion, for it in no way affects our question, and no important deduction can be derived from it.(4) We allude to the point for the mere sake of showing that, up to the last, we have no certain information throwing light on the composition of Tatian's Gospel. All that we do know of it,--what it did not contain--the places where it largely circulated, and the name by which it was {159} called, tends to identify it with the Gospel according to the Hebrews. For the rest, Tatian had no idea of a New Testament Canon, and evidently did not recognize as inspired, any Scriptures except those of the Old Testament.(1) It is well known that the sect of the Encratites made use of apocryphal Gospels until a much later period, and rejected the authority of the Apostle Paul, and Tatian himself is accused of repudiating some of the Pauline Epistles, and of altering and mutilating others.(2) 2. Dionysius of Corinth need not detain us long. Eusebius informs us that he was the author of seven Epistles addressed to various Christian communities, and also of a letter to Chrysophora, "a most faithful sister." Eusebius speaks of these writings as Catholic Epistles, and briefly characterizes each, but with the exception of a few short fragments preserved by him, none of these fruits of the "inspired industry" [------] of Dionysius are now extant.(3) These fragments are all from an Epistle said to have been addressed to Soter, Bishop of Rome, and give us a clue to the time at which they were written. The Bishopric of Soter is generally dated between a.d. 168--176,(4) during which years the Epistle must have been composed. It could not have {160} been written, however, until after Dionysius became Bishop of Corinth in a.d. 170,(1) and it was probably written some years after.(2)
