The Invention of Paper

The invention of paper was one of the most significant changes in the literate world.
Ancient Egyptians created the very first prototype of paper, known as papyrus. Made of papyrus plant, this writing material was cut into stripes, layered, and pressed, as early as 3000B.C. Because papyrus required subtropical conditions to grow, the Romans replaced it later with the parchment made of sheepskin.
On the other side of the world, in China, people dealt with the same needs to record their ideas. As a solution, they invented paper, in 104 AD, using similar principles as we do today. Consisting of tree bark fibers, this advancement included lighter weight, more durable, and abundant elements than previously achieved in the world. Usage of paper became widespread in China by the third century. By the sixth century, its uses extended to wrapping material and toilet paper, and to paper money in the nineth century.
Chinese papermaking techniques initially spread to the Middle East in the eighth century. During the First Crusade, paper got introduced to the medieval Europe along trade routes.
Although paper serves numerous purposes in our daily lives, we often underestimate its importance. Varieties of paper enhance our convenient lifestyles, such as money, newspapers, books, packaging, and technical drafts.
