Papiri

Papiri are sheets of writing material produced from the pith of the papyrus plant (Cyperus papyrus), native to the Nile Delta. The term is used in several languages; in English scholarship the material is typically called papyrus, with the plural papyri used for manuscripts. The sheets were used to record texts in ancient Egypt and throughout the Mediterranean basin for many centuries.

Production involved cutting the stalks into thin strips, layering them crosswise on a flat surface, soaking and pressing the layers together, and drying the resulting sheet. The surface could be polished, and occasional sizing or glue was applied to improve its receptivity to ink.

Papyrus sheets first appear in Egypt in the 3rd millennium BCE and became a standard medium for writing, scrolls, and administrative documents. In the Greek and Roman periods, papyrus remained dominant, used for literary works, letters, and records. Some texts survive today because they were preserved in dry desert environments; many famous papyri were recovered from sites such as Oxyrhynchus and Thebes.

From late antiquity onward, papyrus gradually fell from use as parchment and later paper became more common. Its organic composition makes papyrus vulnerable to humidity and biological decay, so preservation relies on dry, stable conditions. Modern conservation and archaeological excavation often involve careful handling, desiccation control, and digital imaging.

Today, papyrus is studied as a source of ancient language, literature, and administration. In English, papyri is the standard plural for texts written on papyrus; papiri occurs in some languages and historical usage. The term also designates the plant itself and, in modern contexts, a generic term for similar writing materials.
