Researchers have successfully read an entire Herculaneum scroll, known as PHerc. 1667, without physically unrolling it, using high-resolution X-ray scans and machine learning techniques. The scroll contains a philosophical treatise on ethics, likely a Stoic work, and is the first Herculaneum papyrus to be digitally unrolled and read in full. The method used to read the scroll is open and scalable, and the data and code are available for others to use. This breakthrough could lead to the reading of hundreds of other sealed scrolls from the Herculaneum library.
