Toward a Republic of Letters

From Sumerian ledgers toward a republic of letters. Egypt held the reed, Pergamum the hide, China the cheap sheet. Print and learned societies turned copying into correspondence.

1. Writing
2. Papyrus — Sumer wedged cuneiform signs into clay. Egypt had mud too, but the delta grew a reed made for ink.
3. Literature — Ledgers were only the first job. Once marks can live on a portable sheet, the epic outlives the bard.
4. Phonetic alphabet — A phonetic handful of signs lets a scribe write any word he can say.
5. Libraries — Hand-copying and expensive processes make books a luxury. Libraries are more a symbol of power than a source of knowledge.
6. Parchment — Legend blamed an Egyptian papyrus export ban during the rivalry with Pergamum’s library. Pergamum dresses animal skins on frames. The sheet is costly enough to scrape and reuse.
7. Paper — Cheaper than scraped skin, but papermaking still drifts west for centuries.
8. Block printing — Carved blocks and rubbings in China meant one plate could generate hundreds of identical pages. Europe was still copying by hand.
9. Printing press — China already stamped blocks; Gutenberg’s win is movable type combined with a wine press.
10. Scientific societies — Cheap pamphlets turned private letters into public arguments. The Greek Academy is reborn as mail, not marble.
