Parchment

The finer kind of parchment known as vellum is from the skins of calves, kids, and dead-born lambs. The stout parchment of drum-heads is from the skin of the wolf, although that of the a or calf is sometimes used. The parchment of battledores is from the skin of the a , and that used for sieves from the skin of the he-goat. The green parchment used in bookbinding is coloured by means of Verdigris. (See Liber.) The name comes from the Latin Pergamentum. Eumenes, King of Pergamus, has the honour of the invention.
