Overview
- A team using phase‑contrast synchrotron micro‑CT and improved geometric unwrapping has for the first time read the entire surviving surface of PHerc. 1667 without physically opening the roll.
- The recovered segment yields roughly 1.5 metres of continuous ancient Greek across about 20–22 columns and reads as a Stoic ethical treatise that names Aristocreon, linking it to Chrysippus’s circle.
- The project combined three‑dimensional imaging with machine learning trained to detect faint ink textures, producing extremely large datasets at facilities including the ESRF and Diamond Light Source.
- Researchers also identified PHerc. 139 as Philodemus’s On Gods, Book 8 and extracted more than 70 columns from PHerc. 172, while releasing scans and methods publicly to enable wider study.
- The Vesuvius Challenge and University of Kentucky offered a $1 million prize to spur further full scroll reads, but scholars caution that detailed transcription, peer review and scaling to 600+ unopened scrolls will take substantial time and resources.
