There is, however, one ground for hesitation before we ascribe the sections, as well as the canons, to Eusebius; namely, that not a few ancient manuscripts (e.g. Codd. FHY) contain the former, while they omit the latter. Of palimpsests indeed it might be said with reason, that the rough process which so nearly obliterated the ink of the older writing, would completely remove the coloured paint (κιννάβαρις, _vermilion_, prescribed by Eusebius, though blue or green is occasionally found) in which the canons were invariably noted; hence we need not wonder at their absence from the Codices Ephraemi, Nitriensis (R), Dublinensis (Z), Codd. IWb of Tischendorf, and the Wolfenbüttel fragments (PQ), in all which the sections are yet legible in ink. The Codex Sinaiticus contains both; but Tischendorf decidedly pronounces them to be in a later hand. In the Codex Bezae too, as well as the Codex Cyprius (K), even the Ammonian sections, without the canons, are by later hands, though the latter has prefixed the list or table of the canons. Of the oldest copies the Cod. Alex. (A), Tischendorf’s Codd. WaΘ, the Cotton frag. (N), and Codd. Beratinus and Rossanensis alone contain both the sections and the canons. Even in more modern cursive books the latter are often deficient, though the former are present. This peculiarity we have observed in Burney 23, in the British Museum, of the twelfth century, although the Epistle to Carpianus stands at the beginning; in a rather remarkable copy of about the twelfth century, in the Cambridge University Library (Mm. 6. 9, Scholz Evan. 440), in which, however, the table of canons but not the Epistle to Carpianus precedes; in the Gonville and Caius Gospels of the twelfth century (Evan. 59), and in a manuscript of about the thirteenth century at Trinity College, Cambridge (B. x. 17)(73). These facts certainly seem to indicate that in the judgement of critics and transcribers, whatever that judgement may be deemed worth, the Ammonian sections had a previous existence to the Eusebian canons, as well as served for an independent purpose(74).
