Papyrus is a thick paper-like material prouced from the pith of the papyrus plant, Cyperus papyrus, a wetland sedge that was once abundant in the Nile Delta of Egypt. Papyrus usually grows 2–3 meters (5–9 ft) tall. Papyrus is first known to have been used in ancient Egypt (at least as far back as the First dynasty), but it was also used throughout the Mediterranean region. Ancient Egypt used this plant for boats, mattresses, mats and paper.
