Establishment of Paper and Printing

In the early age Egyptians used an early form of paper that was made from grasses called reeds. Hence, the first lightweight medium was papyrus, Later, in the 2nd century ad, the Chinese wrote on silk fabric instead of wood, and developed paper made from silk fibers. (Today paper made from cotton or linen fibers is still called rag paper.) From as early as the 2nd century bc, Europeans wrote on thin layers of tanned and scraped animal skins called parchment or vellum, with quill pens made from bird feathers. Parchment is not as light as papyrus but is very durable; many parchment manuscripts and books from the Middle Ages still exist. The Arabs brought papermaking to Europe from China in the 11th century ad. Paper gave European merchants, who traveled across the continent, a portable and inexpensive way to keep records.

Until the 1400s in Europe, all documents were handwritten. Copyists and editors called scribes recorded commercial transactions, legal decisions and pronouncements, and manuscript copies of religious books—many scribes were monks working in monasteries. By the 15th century, however, the need arose for an easier way to duplicate documents. In Asia, block printing had already been developed by Buddhist monks in China in about the 8th century (see Prints and Printmaking). A similar technique was later used in the 15th century by Europeans to make illustrations for printed books.

An early version of movable type was first developed in China around 1045, and was independently developed by Koreans in the 13th century ad. In 1450 the German printer Johannes Gutenberg perfected movable metal type and introduced the first reliable system of typesetting, a key invention in the development of printing. With movable type, a raised, reversed image of each letter can be hand-set, word by word, into a frame that holds the pieces together. The raised letters are inked, a sheet of paper laid over them and pressed down on the letters with a screw-driven press, creating a correct image of the text. When enough copies are printed, the letters can be taken apart and reused. The technique made printing numerous copies of textual material much easier, and the number of printing shops grew dramatically over the next century.

As more books became available, more people learned to read. Books were printed in the local, or vernacular, languages as well as classical Greek and Latin. With literacy came exposure to new ideas; some historians believe that the 16th-century Protestant Reformation (a revolution in the Christian church that divided it into factions) might not have occurred if European thought had not been prepared by ideas introduced and circulated in printed books. Printers published other things besides books, including newspapers, pamphlets, and broadsides (sheets of paper printed on one or both sides). These cheaper works helped spread news throughout Europe and, in the 17th and 18th centuries, throughout the British colonies in America (see Journalism).

Before paper was invented, many people wrote on scrolls made out of the papyrus plant. By layering, wetting, and then drying layers of the plant’s cellulose together, people could create a fine writing surface. This hieroglyphic scroll is part of the Book of the Dead, from ancient Egypt. Its detailed illustrations demonstrate both the durability and quality of papyrus.
