Virtual Unwrapping Delivers a Stoic Scroll from Herculaneum

Scientists in the Vesuvius Challenge have virtually unwrapped and deciphered PHerc.1667, a 22‑column Greek papyrus from Herculaneum's burnt library, revealing a Stoic ethics treatise. Using X-ray micro-CT scanning, 3D modeling, and semi-automated ink detection, a global team led by Brent Seales at EduceLab publicly documented the full read, marking the first complete scroll solved and highlighting the potential to recover more texts from the Villa of the Papyri.

Lead Ink Could Unveil Herculaneum Scrolls, Researchers Test with Fake Scrolls

Researchers propose that lead in the ink of Herculaneum scrolls could make the writing detectable with X-ray CT, enabling virtual unrolling to reveal text; to test the idea, they created fake scrolls with varying lead concentrations, burned them, scanned with 3D CT, and used an algorithm to extract the text, demonstrating that lead enhances contrast and can be detected by handheld XRF—potentially guiding archaeologists to decipher carbonized scrolls.
