Papyrus is made from a plant that grows on the banks of the Nile River in Egypt. The aquatic plant, Cyperus papyrus, grows up to 15 feet (4.5 meters) high. Its green, triangular stem has long, sharp leaves and flower clusters 10 to 20 inches (25 to 50 cms) long. These flowers bloom at the tip.
Books have been around for thousands of years. When ancient civilizations first started developing writing systems, they would write on just about anything, from stone to tree bark. Ancient Egyptians were the first to use paper-like materials, called papyrus, which they made by pounding flat the woven stems of the papyrus plant. It was not long before the ancient Egyptians began gluing together papyrus sheets to form scrolls, which were the first steps toward books as you know them.
