Manuscript

A lost page from one of the most important scientific manuscripts of antiquity, the Archimedes Palimpsest, has been identified in the collection of the Musée des Beaux-Arts in Blois, central France. The discovery was made by Victor Gysembergh, a researcher at the French National Center for Scientific Research ( CNRS), and represents a significant development in the ongoing effort to recover the lost works of the ancient Greek mathematician Archimedes of Syracuse. The rediscovered folio, identified as leaf 123 of the palimpsest, contains a passage from Archimedes' treatise On the Sphere and the Cylinder, Book I, Propositions 39 to 41 — a foundational text in the history of mathematics. The findings were published on 6 March 2026 in the journal
