On the contents of Bible manuscripts see Zahn, _GK._ i. 62 f. According to him Jerome’s Old Testament was in 14 volumes. In addition to some entire Bibles Cassiodorus had the Scriptures written out in 9 codices. Of these vol. VII. comprised the Gospels, VIII. the Epistles, and IX. the Acts and Apocalypse. Leontius speaks of 6 books of the New Testament, of which probably I. was Mt. and Mk., II. Lk. and Jn., III. Acts, IV. Catholic Epistles, V. Pauline Epistles, VI. Apocalypse. As a rule the Gospels and the Pauline Epistles made two codices. In cod. א we find that the different parts of the New Testament display a different type of text, from which we may conclude that the codex was copied, not from a single manuscript but from several. Similarly, the singular type of text exhibited by cod. Δ in Mark would show that this codex, or that from which it was copied, was transcribed from different rolls or codices, each containing one Gospel. See Zahn, _GK._ i. 63. Bibliotheca. On the designation _Bibliotheca_ and _Pandectes_ for Bible manuscripts, see Zahn, _GK._ i. 65. On τεῦχος, _ibid._ 67. He informs us that the earliest mention of a Christian _bibliotheca_ and its _armaria_ is in the heathen protocol of the year 304, in the _Gesta apud Zenophilum_ given in Dupin after Optatus, p. 262. The next earliest notice is in Augustine. The custodians of the bibliothecae were probably the Readers. In Ruinart’s _Acta Saturnini_ a certain Ampelius is mentioned as “custos legis, scripturarumque divinarum fidelissimus conservator.” From Irenaeus, iv. 33, 2 Lessing concluded that at that time the few existing copies of the Scriptures were in the custody of the clergy, and were only to be perused in their presence.
