Papyrus

Used by the ancient Egyptians to make paper, the papyrus plant has helped to shape the world we live in.

A. 1Libraries and archives are cultural crossroads of knowledge exchange, where the past transmits information to the present, and where the present has the opportunity to inform the future. 1Bureaucracies have become the backbone of civilizations, as governments try to keep track of populations, business transactions and taxes. At a personal level, our lives are governed by the documents we possess; we are certified on paper literally from birth to death. And written documentation carries enormous cultural importance: consider the consequences of signing the Foundation Document of the United Nations or the Convention on Biological Diversity.

Documentation requires a writing tool and a surface upon which to record the information permanently. About 5,000 years ago, the Sumerians started to use reeds or sticks to make marks on mud blocks which were then baked, but despite being fireproof, these were difficult to store. 6Other cultures used more flexible but less permanent surfaces, including animal skins and wood strips. In western culture, the adoption of papyrus was to have a great impact. Sheets of papyrus not only provide an invaluable record of people’s daily lives, they can also be dated using carbon-dating techniques, giving precise information about the age of the text written on them.

B. Papyrus is strongly associated with Egyptian culture, although all the ancient civilizations around the Mediterranean used it. The papyrus sedge is a tall grass-like plant. It was harvested from shallow water and swamplands on the banks of the River Nile. 2Manufacturing sheets of papyrus from papyrus sedge was a complex, messy process. Pith from inside the plant’s stem was cut into long strips that were laid side by side. 7These were then covered with a second layer of strips which were laid at right angles to the first, then soaked in water and hammered together. The sheet was then crushed to extract the water, dried and then polished to produce a high-quality writing surface, individual sheets could be glued together and rolled up to make scrolls or folded and bound to form books.

C. 3-11In moist climates the cellulose-rich sheets of papyrus would readily decay, becoming covered by mould or full of holes from attacks by insects. But in dry climates, such as the Middle East, papyrus is a stable, rot-resistant writing surface. 12The earliest known roll of papyrus scroll was found in the tomb of an official called Hemeka near Memphis, which was then the capital city of Egypt, and is around five thousand years old. 13In 79 CE, nearly 2,000 papyrus scrolls in the library of Julius Caesar’s father-in-law were protected at Herculaneum by ash from the catastrophic eruption of Mount Vesuvius. However, the most famous discoveries of papyrus have come from the rubbish dumps of the ancient town of Oxyrhynchus, some 160km south-west of Cairo, in the desert to the west of the Nile. Oxyrhynchus was a regional administrative capital and for a thousand years generated vast amounts of administrative documentation, including accounts, tax returns and correspondence, which was periodically discarded to make room for more. 3Over time, a thick layer of sand covered these dumps, and they were forgotten. But the documents were protected by the sand, creating a time capsule that allowed astonishing glimpses into the lives of the town’s inhabitants over hundreds of years.

Collections of documents that record information and ideas have frequently been viewed as potentially dangerous. 3-8For thousands of years, governments, despots and conquerors have resorted to burning libraries and books to rid themselves of inconvenient evidence or obliterate cultures and ideas that they found politically, morally or religiously unacceptable. One such calamity, the burning of the Great Library of Alexandria, and the papyrus scrolls and books it contained, has been mythologized and has come to symbolize the global loss of cultural knowledge.

D. 4Besides their use in record-keeping, papyrus stems were used in many other aspects of Mediterranean life, such as for boat construction and making ropes, sails and baskets, as well as being a source of food. 9In 1969 the adventurer Thor Heyerdahl attempted to cross the Atlantic from Morocco in the boat Ra, to show that it was possible for mariners in ancient times to cross the Atlantic Ocean. Ra was made from bundles of papyrus stems and modelled on ancient Egyptian craft. 4As a marshland plant, papyrus sedge stabilizes soils and reduces erosion, while some investigations show that it has potential for water purification and sewage treatment.

E. 5True paper was probably invented in China in the first century CE. Like papyrus, it was constructed from a meshwork of plant fibres, but the Chinese used fibres from the white mulberry tree, which yielded a tough, flexible material that could be folded, stretched, and compressed. 5The adoption of this paper by western cultures soon rendered papyrus obsolete.

5-10Despite dreams of paper-free societies, western cultures still use enormous quantities of paper, often in ways that it would be inconceivable to use papyrus for. As a paper substitute, the role of the papyrus sedge in western cultures has been superseded; papyrus is little more than a niche product for the tourist market. What makes papyrus noteworthy for western societies nowadays is its use as the surface upon which our ancient ancestors recorded their lives, their art and their science. In the words of the ancient Roman philosopher Pliny the Elder, it is ‘the material on which the immortality of human beings depends’.
