Codex Atlanticus

The Basics

Only portions of the 12-volume Codex Atlanticus are on display in the library’s Sala Federiciana and at the adjacent Pinacoteca Ambrosiana gallery. Pages on display at Biblioteca Ambrosiana are usually grouped by subject matter, which ranges from mathematics and astronomy to inventions for war and engineering machines, essays and fables, and even studies and sketches for paintings.

A stop at Biblioteca Ambrosiana can be paired with a private or small-group tour of Milan to see highlights such as the Duomo and Church of Santa Maria delle Grazie, home to da Vinci’sLast Supper. Many city tours include top attractions such as Galleria Vittorio Emanuele II, Pinacoteca di Brera, Sforza Castle, and Navigli canal district. A hop-on hop-off bus tour, Milan Segway tour, and bicycle-powered rickshaw tour are convenient ways to see Milan's attractions.

History of the Codex Atlanticus

Leonardo da Vinci kept extensive notes in code and drew exacting yet enigmatic sketches so his discoveries wouldn't be stolen. In the 16th century, many of those notes were collected by sculptor Pompeo Leoni into what is now known as Codex Atlanticus. It was acquired by the Biblioteca Ambrosiana in the 1630s and later stolen by Napoleon's army. After the Napoleonic occupation, the Codex was returned to Milan, and it's been restored repeatedly.
