Leonardo’s ‘Codex Atlanticus’ Is Complete for the First Time in 400 Years
On June 7, 2026, Florence’s Museo Galileo announced that Leonardo da Vinci’s Codex Atlanticus has been digitally reunited for the first time in roughly 400 years via its updated platform Leonardotheka 2.0. The update adds about 550 pages that sculptor Pompeo Leoni cut from the manuscript in the late 16th century—pages now held by the U.K.’s Royal Collection Trust—to the 1,119-page Codex Atlanticus preserved at Milan’s Veneranda Biblioteca Ambrosiana. The notebook’s contents span from the 1470s to Leonardo’s death in 1519 and include studies for inventions such as a flying machine and a harpsichord-viola. Paolo Galluzzi, president emeritus of Museo Galileo, said the tool expands global scholarly access, and the museum said it has reconstructed 50 additional pages by matching physical and material evidence.
