MATERIALS OF ANCIENT BOOKS.
No material for books has, perhaps, a higher claim to antiquity than the skin of the calf or goat, tanned soft, and which usually was dyed red or yellow: the skins, when thus prepared, were most often connected in lengths, sometimes of a hundred feet, sufficient to contain an entire work; or one book of a history or treatise, which then formed a roll, or volume. These soft skins seem to have been more in use among the Jews and other Asiatics than among the people of Europe. The copies of the Hebrew Scriptures, found in the synagogues of the Jews, are often of this kind: the most ancient manuscripts extant are some copies of the Pentateuch, on rolls of crimson leather.
Parchment—Pergamena, so called long after the time of its first use, from Pergamus, a city of Mysia, where the manufacture was improved and carried on to a great extent, is mentioned by Herodotus and Ctesias, as a material which had been from time immemorial used for books. It has proved itself to be, of all others, except that above mentioned, the most durable. The greater part of all those manuscripts, now in our hands, that are of higher antiquity than the sixth century, are on parchment; as well as, generally, all carefully written, and curiously decorated manuscripts, of later times. The palimpsests, mentioned in a preceding chapter, are usually parchments.
The practice, which is still followed in the East, of writing upon the leaves of trees, is of great antiquity. The leaves of the mallow, or of the palm, were those the most used for this purpose; sometimes they were wrought together so as to form larger surfaces; but it is probable that so fragile and inconvenient a material was employed rather for ordinary purposes of business, letter-writing, and the instruction of children, than for books, intended for preservation.
The inner bark of the linden or teil tree, and perhaps of some others, called by the Romans Liber, by the Greeks Biblos, was so generally used as a material for writing, as to have given its name to a book, in both languages. Tables of solid wood called codices—whence the term codex, for a manuscript, on any material, has passed into common use—were also employed; but this was chiefly for legal documents, on which account a system of laws came to be called—a Code. Leaves or tablets of lead, or of ivory, are frequently mentioned by ancient authors as in common use for writing. But no material or preparation seems to have been so frequently employed, on ordinary occasions, as tablets covered with a thin coat of coloured wax, which might be readily removed by an iron needle, called a style; and from which the writing was as easily effaced, by applying the blunt end of the same instrument.
But during many ages the article most in use, and of which the consumption was so great as to form a principal branch of the commerce of the Mediterranean, was that which was manufactured from the papyrus of Egypt. Many manuscripts written upon this kind of paper in the sixth, and some even so early as the fourth century, are still extant. It formed the material of by far the larger proportion of all books from very early times till about the seventh or eighth century, when it gradually gave place to a still more convenient manufacture—our modern paper.
The papyrus, or reed of Egypt, grew in vast quantities in the stagnant pools that were formed by the annual inundations of the Nile. The plant consists of a single stem, rising sometimes to the height of ten cubits: this stem, gradually tapering from the root, supports a spreading tuft at its summit. The substance of the stem is fibrous, and the pith contains a sweet juice. Every part of this plant was put to some use by the Egyptians—so ingenious and so industrious as they were. The harder and lower part they formed into cups and other utensils; the upper part into staves, or the ribs of boats: the sweet pith was a common article of food; while the fibrous part of the stem was manufactured into cloth, sails for ships, ropes, strings, shoes, baskets, wicks for lamps, and, especially, into paper. For this purpose the fibrous coats of the plant were peeled off, throughout the whole length of the stem. One layer of fibres was then laid across another upon a block, and being moistened, the glutinous juice of the plant formed a cement, sufficiently strong to give coherence to the fibres; when greater solidity was required, a size made from bread or glue was employed. The two films being thus connected, were pressed, dried in the sun, beaten with a broad mallet, and then polished with a shell. This texture was cut into various sizes, according to the use for which it was intended, varying from thirteen, to four fingers’ breadth, and of proportionate length.
By progressive improvements, which were made especially when the manufacture came into the hands of the Roman artists, this Egyptian paper was at length brought to a high degree of perfection. In later ages it was made of considerable thickness—perfect whiteness, and an entire continuity and smoothness of surface. Nevertheless, it was, at the best, so friable, that when durability was required, the copyists inserted a page of parchment between every five or six pages of the papyrus. Thus the firmness of the one substance defended the brittleness of the other; and great numbers of books, constituted in this manner, have resisted the accidents and decays of twelve centuries.
Three hundred years before the Christian era, the commerce in the paper of Egypt had extended over most parts of the civilised world; and long afterwards it continued to be a principal source of wealth to the Egyptians. But at length the invention of another material, and also that interruption of commerce which ensued in consequence of the conquest of Egypt by the Saracens, banished the Egyptian paper from common use. Comparatively few manuscripts on this material are found of later date than the eighth or ninth century; although it continued to be occasionally used long afterwards.
The charta bombycina, or cotton paper, which has often improperly been called silk paper, had unquestionably been manufactured in the East as early as the ninth century, and probably much earlier; and in the tenth century it came into general use throughout Europe. Not long afterwards, this invention was made still more available for general purposes by the substitution of old linen, or cotton rags, for the raw material; for by this means both the price of the article was reduced, and its quality greatly improved. The cotton paper manufactured in the ancient mode is still used in the East, and is a beautiful fabric; it is also extensively used in the United States.
From this account of the materials successively employed for books, it will be obvious, that a knowledge of the changes which these several manufactures underwent from age to age, will often make it easy, and especially when employed in subservience to other evidence, to fix with certainty the date of manuscripts; or at the least, to furnish infallible means for detecting fabricated documents.
The preservation of books, framed as they are of materials so destructible, through a period of twelve, or even fifteen hundred years, is a fact which might seem almost incredible; especially so as the decay of far more durable substances, within a much shorter period, is continually presented to our notice. Yet so it is, that while the massive walls of the monasteries of the middle ages are often seen prostrate, and their materials fast mingling with the soil, the manuscripts, penned within them, or perhaps at a time when these stones were yet in the quarry, are still fair and perfect, and glitter with their gold and silver, their cerulean and their cinnabar.
It must be remembered, however, that the materials of books, although destructible, are so far from being in themselves perishable, that so long as they are defended from positive injuries, they appear to suffer scarcely at all from any intrinsic principle of decay, or to be liable to any perceptible process of chemical decomposition. No one, says Mabillon, unless totally unacquainted with what relates to antiquity, can call in question the great durability of parchments; since there are extant innumerable books, written on that material, in the seventh and sixth centuries; and some of a still more remote antiquity, by which all doubt on that subject might be removed. It may suffice here to mention the Virgil of the Vatican Library, which appears to be of more ancient date than the fourth century; and another in the King’s Library little less ancient: also the Prudentius, in the same library, of equal age; to which you may add several, already mentioned, as the Psalter of S. Germanus, the Book of the Councils, and others, which are all of parchment.
The paper of Egypt, being more frail and brittle, might be open to greater doubt; and yet there are books of great antiquity, by which its durability may be established.
Books have owed their conservation, not merely to the durability of the material of which they were formed; but to the peculiarity of their being, at once precious, and yet (in periods of general ignorance) not marketable articles; they were of inestimable value to a few, while absolutely worthless in the opinion of the multitude. They were also often indebted for their preservation, in periods of disorder and violence, to the sacredness of the roofs under which they were lodged.
