History

According to the Roman Varro, Pliny's Natural History records (xiii.21), parchment was invented under the patronage of Eumenes of Pergamum, as a substitute for papyrus, which was temporarily not being exported from Alexandria, its only source.

Herodotus mentions writing on skins as common in his time, the 5th century BC; and in his Histories (v.58) he states that the Ionians of Asia Minor had been accustomed to give the name of skins — diphtherai — to books; this word was adapted by Hellenized Jews to describe scrolls 1. Parchment (pergamenum in Latin), however, is named after the city where it was perfected. In the 2nd century B.C. a great library was set up in Pergamon that rivaled the famous Library of Alexandria. As prices rose for papyrus and the reed used for making it was overharvested towards local extinction in the two nomes of the Nile delta that produced it, Pergamon adapted by increasing use of parchment.

Writing on prepared animal skins had a long history, however. Some Egyptian Fourth Dynasty texts were written on parchment. Though the Assyrians and the Babylonians impressed their cuneiform on clay tablets, they also wrote on parchment from the 6th century BC onward. Rabbinic culture equated a "book" with a parchment scroll. Early Islamic texts are also found on parchment.

One sort of parchment is vellum, a word that is used loosely to mean parchment, and especially to mean fine parchment, but more strictly refers to parchment made from calf skin (although goat skin can be as fine in quality). The words "vellum" and "veal" come from Latin vitulus, "calf", or its diminutive vitellus. In the Middle Ages calfskin and split sheepskin were the most common materials for making parchment in England and France, while goatskin was more common in Italy. Other skins such as those from large animals such as horse and smaller animals such as squirrel and rabbit were also used. Whether uterine vellum (vellum made from aborted calf fetuses) was ever really used during the medieval period is still a matter of great controversy.

There was a short period during the introduction of printing where parchment and paper were used interchangeably: although most copies of the Gutenberg Bible are on paper, some were printed on parchment. In 1490, Johannes Trithemius preferred the older methods, because "handwriting placed on parchment will be able to endure a thousand years. But how long will printing last, which is dependent on paper? For if ...it lasts for two hundred years that is a long time."
