**verifies**: [[question-verify-vesuvius-pherc-1667-first-scroll-read]]

The Vesuvius Challenge team (21 authors spanning Vesuvius Challenge,
EduceLab/University of Kentucky, ESRF, and several European universities,
including [[entity-brent-seales|Brent Seales]] and Nat Friedman) published a
formal arXiv preprint on 27 June 2026 restating and technically
substantiating [[claim-pherc-1667-first-herculaneum-scroll-read-unopened|the
original "first complete scroll" claim]]: "This makes PHerc. 1667 the first
Herculaneum papyrus to be fully digitally unrolled and read for extended
scholarly study without physical opening." The preprint gives quantitative
detail absent from the original scrollprize.org announcement — the
reconstructed surface contains 22 columns or column-equivalents over
approximately 860 cm² of preserved writing surface, with untranscribed
material restricted to 33 cm² across the first three columns where ink
traces cannot be securely read. This is a Tier 1 primary source and clears
the sourcing floor for the quantitative figures, but it is authored by the
same team that runs scrollprize.org — it upgrades the documentation from a
promotional blog post to a peer-review-track scientific preprint, without
being independent of the prize's own venue for the priority claim itself.

Independent mainstream journalism did cover the announcement: Smithsonian
Magazine's Ellen Wexler reported, "Now, for the very first time, researchers
have recovered all surviving text from a single scroll," rounding the
result to "a nearly five-foot-long segment" and "roughly 20 columns"
(compatible with, though less precise than, the preprint's figures). Wexler
also quotes Thomas Coward, a University of Bristol classicist explicitly
identified as not part of the Vesuvius Challenge, on the scholarly value of
the recovered text — but his remark addresses the importance of having a
source text, not the "first ever" priority claim itself. No independent
papyrologist, classics journal, or institution not already party to the
project was found stating or adjudicating the priority claim independently
this session.

The claim is therefore `[unverified-priority — the "first" claim itself
still rests on the project's own publications; no independent Tier 1–2
confirmation located this session]`. See the linked question's leads (CNN's
coverage 451'd this session; ESRF's own news page 403'd; National
Geographic and New Scientist reporting unread) for what would close it.
