13. Breathings (_spiritus_) and accents(46) were not applied systematically to Greek Texts before the seventh century. But a practice prevailed in that and the succeeding century of inserting them in older manuscripts, where they were absent _primâ manu_. That such was done in many instances (e.g. in Codd. Vatican. and Coislin. 202 or H of St. Paul) appears clearly from the fact that the passages which the scribe who retouched the old letters for any cause left unaltered, are destitute of these marks, though they appear in all other places. Cod. א exhibits breathings, apparently by the original scribe, in Tobit vi. 9; Gal. v. 21 only. The case of Cod. Alexandrinus is less easy. Though the rest of the book has neither breathings (except a few here and there) nor accents, the first four lines of _each_ column of the book of Genesis (see facsimile No. 12), which are written in red, are fully furnished with them. These marks Baber, who edited the Old Testament portion of Cod. A, pronounced to be by a second hand (Notae, p. 1); Sir Frederick Madden, a more competent judge, declares them the work of the original scribe (Madden’s Silvestre, Vol. i. p. 194, note), and after repeated examination we know not how to dissent from his view(47). So too in the Sarravian Pentateuch of the fifth century we read ΤΟΝΥΝ [with several symbols written over the Υ] (Lev. xi. 7) by the first hand. The Cureton palimpsest of Homer also has them, though they are occasionally obliterated, and some few are evidently inserted by a corrector; the case is nearly so with the Milan Homer edited by Mai; and the same must be stated of the Vienna Dioscorides (Silvestre, No. 62), whose date is fixed by internal evidence to about A.D. 500. In the papyrus fragment of the Psalms, now in the British Museum, the accents are very accurate, and the work of the original scribe. These facts, and others like these, may make us hesitate to adopt the notion generally received among scholars on the authority of Montfaucon (Palaeogr. Graec. p. 33), that breathings and accents were not introduced _primâ manu_ before the seventh or eighth century; although up to that period, no doubt, they were placed very incorrectly, and often omitted altogether. The breathings are much the more ancient and important of the two. The _spiritus lenis_ indeed may be a mere invention of the Alexandrian grammarians of the second or third century before Christ, but the _spiritus asper_ is in fact the substitute for a real letter (H) which appears on the oldest inscriptions; its original shape being the first half of the H ([symbol like the left half of a Roman capital letter H]), of which the second half was subsequently adopted for the _lenis_ ([symbol like the right half of a Roman capital H]). This form is sometimes found in manuscripts of about the eleventh century (e.g. Lebanon, B.M. Addit. 11300 or kscr, and usually in Lambeth 1178 or dscr) ed. of 1550, but even in the Cod. Alexandrinus the comma and inverted comma are several times substituted to represent the _lenis_ and _asper_ respectively (facsimile No. 12): and at a later period this last was the ordinary, though not quite the invariable, mode of expressing the breathings. Aristophanes of Byzantium (keeper of the famous Library at Alexandria under Ptolemy Euergetes, about B.C. 240), though probably not the inventor of the Greek accents, was the first to arrange them in a system. Accentuation must have been a welcome aid to those who employed Greek as a learned, though not as their vernacular tongue, and is so convenient and suggestive that no modern scholar can afford to dispense with its familiar use: yet not being, like the rough breathing, an essential portion of the language, it was but slowly brought into general vogue. It would seem that in Augustine’s age [354-430] the distinction between the smooth and rough breathing in the manuscripts was just such a point as a careful reader would mark, a hasty one overlook(48). Hence it is not surprising that though these marks are entirely absent both from the Theban and Herculanean papyri, a few breathings are apparently by the first hand in Cod. Borgianus or T (Tischendorf, N. T. 1859, Proleg. p. cxxxi). One rough breathing is just visible in that early palimpsest of St. John’s Gospel, Ib or Nb. Such as appear, together with some accents, in the Coislin Octateuch of the sixth or seventh century, may not the less be _primâ manu_ because many pages are destitute of them; those of Cod. Claromontanus, which were once deemed original, are now pronounced by its editor Tischendorf to be a later addition. Cod.
