The Codex Atlanticus (Atlantic Codex) is a 12-volume, bound set of drawings and writings (in Italian) by Leonardo da Vinci, the largest single set. Its name indicates the large paper used to preserve original Leonardo notebook pages, which was used for atlases. It comprises 1,119 leaves dating from 1478 to 1519, the contents covering a great variety of subjects, from flight to weaponry to musical instruments and from mathematics to botany. This codex was gathered in the late 16th century by the sculptor Pompeo Leoni, who dismembered some of Leonardo's notebooks in its formation. It is now in the Biblioteca Ambrosiana in Milan.
