On 25 June 2026, the Vesuvius Challenge announced that PHerc. 1667 — a
carbonized Herculaneum papyrus of roughly 1.4 m and about 22 columns of Greek —
had been read from beginning to end without ever being physically opened, which
the project describes as the first time a complete scroll has been recovered this
way. The scroll was scanned by high-resolution X-ray microtomography at the ESRF
synchrotron, its wound sheet reconstructed and digitally flattened, and its text
made legible by machine-learning ink-detection models: "we never unrolled it
physically... we scanned it with high-resolution X-rays, reconstructed the wound
sheet inside the volume, flattened it into a readable surface, and used machine
learning to bring out the faint traces of ancient ink." The recovered text is
reported as a 2nd-century BC Stoic ethics treatise on moral progress that
references Aristocreon, the nephew of Chrysippus. The same announcement
presents two further scrolls as separate milestones rather than as second
full readings: in PHerc. Paris 4 (the community's "Scroll 1") a
higher-resolution imaging technique made the ink directly visible inside the
scroll, matching the text read for the 2023 Grand Prize; in PHerc. 139 the
title and author were recovered — Philodemus, *On Gods*, Book 8 *(the
promotion wording had "two further scrolls were said to be partially
identified by the same method"; corrected against the page 2026-09-11)*.

The event is the payoff of the [[claim-virtual-unwrapping-first-proved-on-2015-en-gedi-scroll|virtual-unwrapping research program]]
begun by [[entity-brent-seales|Brent Seales]], and it extends a longer lineage of recovering text the eye
cannot see — the same underlying problem attacked by
[[claim-sinai-palimpsests-multispectral-imaging-recovered-erased-texts|multispectral imaging of erased palimpsests]].
Mechanically it is an [[claim-ai-inference-means-running-a-model|inference task]]:
a trained model run over a 3-D volume to classify ink versus blank papyrus. It
also connects to the vault's document-technology thread about who — or what — can
still read a format the naked eye has lost, alongside notes like
[[claim-internet-archive-2016-stopped-generating-djvu]].
