THE INVENTION OF PRINTING
The present day is notably distinguished by the prevalence of enormous numbers of printed books, periodicals, and newspapers. Yet this very printing, which seems so commonplace to us now, has had, in all, but a comparatively brief existence. From the earliest recorded history up to less than five hundred years ago every book in Europe [Footnote: For an account of early printing in China, Japan, and Korea, see the informing article "Typography" in the Encyclopædia Britannica, 11th edition, Vol. XXVII, p. 510.] was laboriously written by hand, [Footnote: It is interesting to note the meaning of our present word "manuscript," which is derived from the Latin—manu scriptum ("written by hand").] and, although copyists acquired an astonishing swiftness in reproducing books, libraries of any size were the property exclusively of rich institutions or wealthy individuals. It was at the beginning of modern times that the invention of printing revolutionized intellectual history.
Printing is an extremely complicated process, and it is small wonder that centuries of human progress elapsed before its invention was complete. Among the most essential elements of the perfected process are movable type with which the impression is made, and paper, on which it is made. A few facts may be conveniently culled from the long involved story of the development of each of these elements.
[Sidenote: Development of paper]
For their manuscripts the Greeks and Romans had used papyrus, the prepared fiber of a tough reed which grew in the valley of the Nile River. This papyrus was very expensive and heavy, and not at all suitable for printing. Parchment, the dressed skins of certain animals, especially sheep, which became the standard material for the hand- written documents of the middle ages, was extremely durable, but like papyrus, it was costly, unwieldy, and ill adapted for printing.
The forerunner of modern European paper was probably that which the Chinese made from silk as early as the second century before Christ. For silk the Mohammedans at Mecca and Damascus in the middle of the eighth century appear to have substituted cotton, and this so-called Damascus paper was later imported into Greece and southern Italy and into Spain. In the latter country the native-grown hemp and flax were again substituted for cotton, and the resulting linen paper was used considerably in Castile in the thirteenth century and thence penetrated across the Pyrenees into France and gradually all over western and central Europe. Parchment, however, for a long time kept its preeminence over silk, cotton, or linen paper, because of its greater firmness and durability, and notaries were long forbidden to use any other substance in their official writings. Not until the second half of the fifteenth century was assured the triumph of modern paper, [Footnote: The word "paper" is derived from the ancient "papyrus.">[ as distinct from papyrus or parchment, when printing, then on the threshold of its career, demanded a substance of moderate price that would easily receive the impression of movable type.
[Sidenote: Development of Movable Type]
The idea of movable type was derived from an older practice of carving reverse letters or even whole inscriptions upon blocks of wood so that when they were inked and applied to writing material they would leave a clear impression. Medieval kings and princes frequently had their signatures cut on these blocks of wood or metal, in order to impress them on charters, and a kind of engraving was employed to reproduce pictures or written pages as early as the twelfth century.
It was a natural but slow evolution from block-impressing to the practice of casting individual letters in separate little pieces of metal, all of the same height and thickness, and then arranging them in any desired sequence for printing. The great advantage of movable type over the blocks was the infinite variety of work which could be done by simply setting and resetting the type.
The actual history of the transition from the use of blocks to movable type—the real invention of modern printing—is shrouded in a good deal of mystery and dispute. It now appears likely that by the year 1450, an obscure Lourens Coster of the Dutch town of Haarlem had devised movable type, that Coster's invention was being utilized by a certain Johan Gutenberg in the German city of Mainz, and that improvements were being added by various other contemporaries. Papal letters of indulgence and a version of the Bible, both printed in 1454, are the earliest monuments of the new art.
Slowly evolved, the marvelous art, once thoroughly developed, spread with almost lightning rapidity from Mainz throughout the Germanics, the Italian states, France, and England,—in fact, throughout all Christian Europe. It was welcomed by scholars and applauded by popes. Printing presses were erected at Rome in 1466, and book-publishing speedily became an honorable and lucrative business in every large city. Thus, at the opening of the sixteenth century, the scholarly Aldus Manutius was operating in Venice the famous Aldine press, whose beautiful editions of the Greek and Latin classics are still esteemed as masterpieces of the printer's art.
The early printers fashioned the characters of their type after the letters that the scribes had used in long-hand writing. Different kinds of common hand-writing gave rise, therefore, to such varieties of type as the heavy black-faced Gothic that prevailed in the Germanics or the several adaptations of the clear, neat Roman characters which predominated in southern Europe and in England. The compressed "italic" type was devised in the Aldine press in Venice to enable the publisher to crowd more words upon a page.
[Sidenote: Results of Invention of Printing]
A constant development of the new art characterized the sixteenth century, and at least three remarkable results became evident. (1) There was an almost incalculable increase in the supply of books. Under earlier conditions, a skilled and conscientious copyist might, by prodigious toil, produce two books in a year. Now, in a single year of the sixteenth century, some 24,000 copies of one of Erasmus's books were struck off by one printing press.
(2) This indirectly increased the demand for books. By lessening the expense of books and enabling at least all members of the middle class, as well as nobles and princes, to possess private libraries, printing became the most powerful means of diffusing knowledge and broadening education.
(3) A greater degree of accuracy was guaranteed by printing than by manual copying. Before the invention of printing, it was well-nigh impossible to secure two copies of any work that would be exactly alike. Now, the constant proof-reading and the fact that an entire edition was printed from the same type were securities against the anciently recurring faults of forgery or of error.
