Papyrus (Papy`rus) , the Greek name of the Egyptian papu, is a kind of sedge growing 10 ft. high, with a soft triangular stem, the pith of which is easily split into ribbons, found still in Egypt, Nubia, Abyssinia, &c.; the pith ribbons were the paper of the ancient Egyptians, of the Greeks after Alexander, and of the later Romans; they were used by the Arabs of the 8th century, and in Europe till the 12th; at first long strips were rolled up, but later rectangular pages were cut and bound together book fashion; though age has rendered the soft white pages brown and brittle, much ancient literature is still preserved on papyrus; the use of papyrus was superseded by that of parchment and rag-made paper.
