CHAP. 24.—THE MODE OF TESTING THE GOODNESS OF PAPER.
There is a great difference in the breadth of the various kinds of paper. That of best quality894 is thirteen fingers wide, while the hieratica is two fingers less. The Fanniana is ten fingers wide, and that known as “amphitheatrica,” one less. The Saitic is of still smaller breadth, indeed it is not so wide as the mallet with which the paper is beaten; and the emporetica is particularly narrow, being not more than six fingers in breadth.
In addition to the above particulars, paper is esteemed according to its fineness, its stoutness, its whiteness, and its smoothness. Claudius Cæsar effected a change in that which till then had been looked upon as being of the first quality: for the Augustan paper had been found to be so remarkably fine, as to offer no resistance to the pressure of the pen; in addition to which, as it allowed the writing upon it to run through, it was continually causing apprehensions of its being blotted and blurred by the writing on the other side; the remarkable transparency, too, of the paper was very unsightly to the eye. To obviate these inconveniences, a groundwork of paper was made with leaves of the second quality, over which was laid a woof, as it were, formed of leaves of the first. He increased the width also of paper; the width [of the common sort] being made a foot, and that of the size known as “macrocollum,”895 a cubit; though one inconvenience was soon detected in it, for, upon a single leaf896 being torn in the press, more pages were apt to be spoilt than before.897 In consequence of the advantages above-mentioned, the Claudian has come to be preferred to all other kinds of paper, though the Augustan is still used for the purposes of epistolary correspondence. The Livian, which had nothing in common with that of first quality, but was entirely of a secondary rank, still holds its former place.
