Prof. Brent Seales at the University of Kentucky pioneered virtual scroll unwrapping, launching the Vesuvius Challenge in 2023. X-ray scanning and machine learning now fully read scroll PHerc 1667 from the Villa of the Papyri—a 2nd-century BCE Stoic treatise referencing Aristocreon, nephew of philosopher Chrysippus. It's the first complete Herculaneum scroll read continuously end-to-end.
