Recovered text

Epicurean prose (author/title not yet identified) · Greek

Scroll 1 — the flagship. Substantial continuous Greek text recovered from the banner and body; site of the 2023 First Letters and Grand Prize.

⚠️ The title region shows no detectable ink (possibly a different ink; the top rows are physically missing).

Carbonized by the eruption of Mount Vesuvius in AD 79 and buried in the Villa of the Papyri at Herculaneum — the only library to survive from classical antiquity. Recovered in excavations begun in 1752; too fragile to open physically, it is read non-invasively via X-ray tomography and virtual unwrapping.  ·  ash2txt data browser · scrollprize.org/data
