7. While papyrus remained in common use, the chief instrument employed was a reed (κάλαμος 3 John ver. 13, _canna_), such as are common in the East at present: a few existing manuscripts (e.g. the Codd. Leicestrensis and Lambeth 1350) appear to have been thus written. Yet the firmness and regularity of the strokes, which often remain impressed on the vellum or paper after the ink has utterly gone, seem to prove that in the great majority of cases the _stilus_ made of iron, bronze, or other metal, or ivory or bone, sharp at one end to scratch the letters, and furnished with a knob or flat head at the other for purposes of erasure, had not gone wholly out of use. We must add to our list of Writing materials a bodkin or needle (_acus_), by means of which and a ruler the blank leaf was carefully divided, generally on the outer side of the skin, into columns and lines, whose regularity much enhances the beauty of our best copies. The vestiges of such points and marks may yet be seen deeply indented on the surface of nearly all manuscripts, those on one side of each leaf being usually sufficiently visible to guide the scribe when he came to write on the reverse. The quill pen probably came into use with vellum, for which it is obviously suited. The first notices of it occur in a story respecting Theodoric the Ostrogoth, and in a passage of Isidore’s “Origines”(26) (vi. 13). 8. Little need be said respecting the _form_ of manuscripts, which in this particular (_codices_) much resemble printed books. A few are in large folio; the greater part in small folio or quarto, the prevailing shape being a quarto (_quaternio_ or quire) whose height but little exceeds its breadth; some are in octavo, a not inconsiderable number smaller still: and quires of three sheets or six leaves, and five sheets or ten leaves (Cod. Vaticanus), are to be met with. In some copies the sheets have marks in the lower margin of their first or last pages, like the _signatures_ of a modern volume, the folio at intervals of two, the quarto at intervals of four leaves, as in the Codex Bezae of the Gospels and Acts (D), and the Codex Augiensis of St. Paul’s Epistles (F). Not to speak at present of those manuscripts which have a Latin translation in a column parallel to the Greek, as the Codex Bezae, the Codex Laudianus of the Acts, and the Codices Claromontanus and Augiensis of St. Paul, many copies of every age have two Greek columns on each page; of these the Codex Alexandrinus is the oldest: the Codex Vaticanus has three columns on a page, the Codex Sinaiticus four. The unique arrangement(27) of these last two has been urged as an argument for their higher antiquity, as if they were designed to imitate _rolled_ books, whose several skins or leaves were fastened together lengthwise, so that their contents always appeared in parallel columns; they were kept in scrolls which were unrolled at one end for reading, and when read rolled up at the other. This fashion prevails in
