Codex Atlanticus
manuscript codex by Leonardo da Vinci

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.
Description
The Codex Atlanticus is the largest single collection of drawings and writings (in Italian) by polymath Leonardo da Vinci, containing 1,119 paper leaves (2,238 pages) arranged into 12 leather-bound volumes. Its size and scope has led art historian Carlo Pedretti to recognize it as the most important of Leonardo's manuscripts. The pages are in various sizes, "from folded sheets to minute fragments." They range from 1478 to 1519 and cover Leonardo's entire professional career through Florence, Milan, Rome, and Amboise.
Contents
The codex contains drawings and writings on a diverse range of subjects, including studies and sketches for paintings, works on mechanics, hydraulics, mathematics, astronomy as well as philosophical meditations and fables. It also has many inventions such as parachutes, war machineries and hydraulic pumps.
