Vellum

Entertainment / Literature / Vellum: The skin of a young calf used as a writing surface--the medieval equivalent of 'paper.' A technical distinction is usually made between vellum and parchment, the latter is made from goatskin or sheepskin. Uterine vellum--the skin of stillborn or very young calves, is characterized by small size and particularly fine, white appearance. As Michelle P. Brown notes in Understanding Illuminated Manuscripts, the process for creating vellum or parchment is quite complicated: To produce parchment or vellum, the animal skins were defleshed in a bath of lime, stretched on a frame, and scraped with a lunular knife while damp. They could then be treated with pumice, whitened with a substance such as chalk, and cut to size. Differences in preparation technique seem to have occasioned greater diversity in appearance than did the type of skin used. Parchment supplanted papyrus as the most popular writing support material in the fourth century, although it was known earlier. Parchment was itself largely replaced by paper in the sixteenth century (with the rise of printing) but remained in use for certain high-grade books. (95)
