The Codex Mendoza was created under the orders of Viceroy Antonio de Mendoza to evoke an economic, political, and social panorama of the recently conquered lands. It was made in 1542 and since 1659 it has been in the collection of the Bodleian Library. This digital edition of the Codex Mendoza represents the first attempt to create a digital resource that permits in-depth study of a Mexican codex.
