Egypt also was a center of alchemy research for much of the western world . </P> <P> The word paper comes from the Greek term for the ancient Egyptian writing material called papyrus, which was formed from beaten strips of papyrus plants . Papyrus was produced in Egypt as early as 3000 BC, and was sold to ancient Greece and Rome . The establishment of the Library of Alexandria limited the supply of papyrus for others . According to the Roman historian Pliny (Natural History records, xiii. 21), as a result of this, parchment was invented under the patronage of Eumenes II of Pergamon to build his rival library at Pergamon .
