Vellum is derived from the Latin word "vitulinum" meaning "made from calf", leading to Old French "vélin" ("calfskin").〔(【引用サイトリンク】title=vellum )〕 The term often refers to a parchment made from calf skin, as opposed to that from other animals.〔 It is prepared for writing or printing on, to produce single pages, scrolls, codices or books. The term is sometimes used with a more general meaning referring to finer-quality parchments made from a variety of animal skins. Vellum is generally smooth and durable, although there are great variations depending on preparation and the quality of the skin. The manufacture involves the cleaning, bleaching, stretching on a frame (a "herse"), and scraping of the skin with a crescent shaped knife (a "lunarium" or "lunellum"). To create tension, scraping is alternated with wetting and drying. A final finish may be achieved by abrading the surface with pumice, and treating with a preparation of lime or chalk to make it accept writing or printing ink.〔http://www.archives.gov/preservation/formats/paper-vellum.html〕 Modern "paper vellum" (vegetable vellum) is a quite different synthetic material, used for a variety of purposes, including plans, technical drawings, and blueprints. ==Terminology== In Europe, from Roman times, the term vellum was used for the best quality of prepared skin, regardless of the animal from which the hide was obtained, calf, sheep, and goat all being commonly used (other animals, including pig, deer, donkey, horse, or camel have been used). Although the term derives from the French for "calf", except for Muslim or Jewish use, animal vellum can include hide from virtually any other mammal. The best quality, "uterine vellum", was said to be made from the skins of stillborn or unborn animals, although the term was also applied to fine quality skins made from young animals. French sources, closer to the original etymology, tend to define ''velin'' as from calf only, while the British Standards Institution defines parchment as made from the split skin of several species, and vellum from the unsplit skin.〔Young, Laura, A., ''Bookbinding & conservation by hand: a working guide'', Oak Knoll Press, 1995, ISBN 1-884718-11-6, ISBN 978-1-884718-11-3, (Google books )〕 In the usage of modern practitioners of the artistic crafts of writing, illuminating, lettering, and bookbinding, "vellum" is normally reserved for calfskin, while any other skin is called "parchment".〔Johnston, E.
