regional classification, date, physical description, description of the work itself, a bibliographical essay, list of copies, and a bibliography. Indigenous texts known as Techialoyan manuscripts are written on native paper (amatl) are also surveyed. They follow a standard format, usually written in alphabetic Nahuatl with pictorial content concerning a meeting of a given indigenous pueblo's leadership and their marking out the boundaries of the municipality. A type of colonial-era pictorial religious texts are catechisms called Testerian manuscripts. They contain prayers and mnemonic devices. An interesting type of pictorial codex are ones deliberately falsified. John B. Glass published a catalog of such manuscripts that were published without the forgeries being known at the time. Another mixed alphabetic and pictorial source for Mesoamerican ethnohistory is the late sixteenth-century Relaciones geográficas, with information on individual indigenous settlements in colonial Mexico, created on the orders of the Spanish crown. Each relación was ideally to include a pictorial of the town, usually done by an indigenous resident connected with town government. Although these manuscripts were created for Spanish administrative purposes, they contain important information about the history and geography of indigenous polities. Important codices 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. The colonial-era codices often contain Aztec pictograms or other pictorial elements. Some are written in alphabetic text in Classical Nahuatl (in the Latin alphabet) or Spanish, and occasionally Latin. Some are entirely in Nahuatl without pictorial content. Although there are very few surviving prehispanic codices, the (codex painter) tradition endured the transition to colonial culture; scholars now have access to a body of around 500 colonial-era codices. Some prose manuscripts in the indigenous tradition sometimes have pictorial content, such as the Florentine
