other writers and sects, to one of whom with infinitely greater propriety this expression applies. No weight, therefore, could be attached to any such passage in connection with Tatian. Moreover the quotation not only does not agree with our Synoptic, but may much more probably have been derived from the Gospel according to the Hebrews.(1) It will be remembered that Justin Martyr quotes the same passage, with the same omission of "[------]," from a Gospel different from our Synoptics.(2) Tatian, however, is claimed by apologists as a witness for the existence of our Gospels--more than this he could not possibly be--principally on the ground that his Gospel was called by some Diatessaron [------] or "by four," and it is assumed to have been a harmony of four Gospels. The work is no longer extant and, as we shall see, our information regarding it is of the scantiest and most unsatisfactory description. Critics have arrived at very various conclusions with regard to the composition of the work. Some of course affirm, with more or less of hesitation nevertheless, that it was nothing else than a harmony of our four canonical Gospels;(3) many of these, however, are constrained to admit that it was also partly based upon the Gospel according to the Hebrews.(4) Some maintain that it was {149} a harmony of our three Synoptics together with the Gospel according to the Hebrews;(1) whilst many deny that it was composed of our Gospels at all,(2) and either declare it to have been a harmony of the Gospel according to the Hebrews with three other Gospels whose identity cannot be determined, or that it was simply the Gospel according to the Hebrews itself,(3) by which name, as Epiphanius states, it was called by some in his day.(4) Tatian's Gospel, however, was not only called Diatessaron, but, according to Victor of Capua, it was also called Diapente [------] "by five,"(5) a complication which shows the incorrectness of the ecclesiastical theory of its composition. Tischendorf, anxious to date Tatian's Gospel as early as possible, says that in all probability it was composed earlier than the address to the Greeks.(6) Of this, however, he does not offer any evidence, and upon {150}
