Parchment consists of skins specially prepared for writing on, and is so called from a king of Pergamos, who introduced it when the export of papyrus from Egypt was stopped; the skins used are of sheep, for fine parchment or vellum, of calves, goats, and lambs; parchment for drumheads is made from calves' and asses' skins.
