THE ADVANCES OF PAPER AND PAINTS


In Egypt people wrote on papyrus, which is a plant material that grows in a river called Nilo. In Europe, we used the parchment during the Middle Ages this was made of goatskin and we write in it whith ink, but it changes in a few years because this type of writing was very expensive.
