Overview
- Researchers matched the Blois leaf to Heiberg’s 1906 photographs, confirming it as leaf 123 of the palimpsest.
- The page preserves geometric diagrams and a passage from On the Sphere and the Cylinder beneath later prayer‑book writing.
- The reverse shows a Prophet Daniel image reported to have been added in the 20th century to increase value, complicating recovery of the original script.
- CNRS will use X‑ray fluorescence and multispectral methods over the next year to reveal hidden passages and reassess previously illegible pages.
- Two leaves remain unlocated, and CNRS researcher Victor Gysembergh is credited with the discovery at the Musée des Beaux‑Arts in Blois.
