Leonardo da Vinci's Codex Atlanticus Reunited Digitally After 400 Years

digital · 2026-06-08

In Florence, the Galileo Museum has successfully digitally restored Leonardo da Vinci's Codex Atlanticus, which had been fragmented for 400 years, with over 500 pages removed in the late 16th century. The museum introduced Leonardotheka 2.0, incorporating 550 pages, previously excised by sculptor Pompeo Leoni and now part of the U.K.'s Royal Collection Trust, into the original 1,119-page manuscript housed at Milan's Veneranda Biblioteca Ambrosiana. Created between the 1470s and 1519, the Codex features designs such as the flying machine. Leoni categorized the pages into artistic and technical collections. Since its inception in 2023, Leonardotheka has reconstructed 50 new pages, enabling users to explore documents by content and technique. Executive director Roberto Ferrari highlighted the importance of cultural institutions' intellectual ownership in digital initiatives.
