Leonardo//thek@-Codex Atlanticus is an innovative digital repository that provides access to images and transcriptions of the nearly 1200 pages of the Codex Atlanticus, and to the results of over two centuries of scholarly work on this resource. Thanks to the multiplicity and variety of the research tools, the repository constitutes an indispensable means for exploring the vast and chaotic ocean of data stored within the Codex. 

Leonardo//thek@-Codex Atlanticus represents the first step in an ambitious project: to reconstruct the state of Leonardo’s manuscripts before the disastrous intervention by Pompeo Leoni, the Aretine sculptor who, in the late 16th century, dismembered and mutilated many of Da Vinci’s notebooks and loose sheets, distributing them between two large albums, one of which, the Codex Atlanticus, is today preserved in the Ambrosiana Library, Milan, and the other in the Royal Library, Windsor. 

Currently nearing completion, the second step of the project, Leonardo//thek@-Royal Collection, will complement the Codex Atlanticus platform, making it possible to investigate the two gigantic digital archives either separately or as an integrated resource.
