To these _a priori_ and negative considerations must be added the positive argument of Krall (Mitt. i. p. 111). He appears to have discovered earlier forms of the Bohairic dialect, and in addition points out that some of the commonest abbreviations in Coptic MSS. could only have been derived from the Bohairic, which seems to show that it was for Bohairic that the alphabet was first used. And this in the New Testament at any rate is supported by the text of the version. A study of this has shown that in the form in which we possess it in most printed editions and late MSS., although as a whole its agreement with the oldest Greek MSS. is undoubted, it contains a considerable number of later additions which agree with the traditional text. But, as Bishop Lightfoot showed, these clearly formed no part of the original Bohairic version, and subsequent investigation has made it clear that the evidence in favour of this statement is even stronger than he represented it (_see_ Sanday, Appendices ad Novum Testamentum, App. III. p. 182 sq.). The original Bohairic text then represents a very pure tradition, untouched by the so-called Western additions which are found in the Sahidic version, and it is difficult to believe that a version so singularly free from these should be later than the Sahidic. Christianity spread in the Thebaid certainly as early as the beginning of the third century (Eus. “H. E.” vi. 1), and that century is the period to which internal evidence would assign the origin of the Sahidic version. An even earlier date is probably demanded both for the extension of Christianity in the Delta and for the text of the Bohairic version.] (3) The Sahidic (or Thebaic) Version. The Sahidic version did not attract attention till a comparatively late date. When Wilkins published what was then called the Coptic New Testament, he mentioned having found among the Oxford MSS. two which he described as “lingua plane a reliquis MSS. Copticis, quae unquam vidi, diversa” (Praef. p. vii). These are written in the Thebaic or Sahidic dialect, of which as we may infer from his language, he did not even know the existence. After no long time, however, we find La Croze and Jablonski, with other Egyptian scholars, turning their attention to the dialect of Upper Egypt: and at length in 1778, C. G. Woide issued a prospectus in which he announced his intention of publishing from Oxford MSS. the fragments of the New Testament “juxta interpretationem dialecti Superioris Aegypti, quae Thebaidica seu Sahidica appellatur.” In the same year he gave to the world some various readings of this version in J. A. Cramer’s “Beyträge zur Beförderung theologischer und andrer wichtigen Kenntnisse,” Pt. iii, Kiel u. Hamburg, 1778. But before Woide’s work appeared he was partially anticipated by other labourers in the same field.
