PHerc. 1667 was virtually unwrapped and read in full in June 2026, giving scholars 22 columns of Greek across about 1.4 meters of papyrus.
The text appears to be a Stoic ethical treatise on human nature, impulse and moral progress, recovered without physically opening a scroll that would otherwise crumble.
The breakthrough came from X-ray microtomography, computer-vision tools and papyrologists’ feedback, built through the open Vesuvius Challenge competition launched in 2023.
Hundreds of participants contributed to milestones from first words to the first complete scroll, and some community members became core researchers on the project.
The result opens a path to reading hundreds more Villa of the Papyri scrolls, though badly compressed or contaminated examples may still require better scans and automation.
