Particularly important colonial-era codices that are published with scholarly English translations are Codex Mendoza, the Florentine Codex, and the works by Diego Durán. Codex Mendoza is a mixed pictorial, alphabetic Spanish manuscript. Of supreme importance is the Florentine Codex, a project directed by Franciscan friar Bernardino de Sahagún, who drew on indigenous informants' knowledge of Aztec religion, social structure, natural history, and includes a history of the Spanish conquest of the Aztec Empire from the Mexica viewpoint. The project resulted in twelve books, bound into three volumes, of bilingual Nahuatl/Spanish alphabetic text, with illustrations by native artists; the Nahuatl has been translated into English. Also important are the works of Dominican Diego Durán, who drew on indigenous pictorials and living informants to create illustrated texts on history and religion.
