Diego Durán (c. 1537–1588) was a Dominican friar best known for his authorship of one of the earliest Western books on the history and culture of the Aztecs, The History of the Indies of New Spain, a book that was much criticized in his lifetime for helping the "heathen" maintain their culture. Also known as the Durán Codex, The History of the Indies of New Spain was published c. 1581. Durán also wrote Book of the Gods and Rites (1574-1576), and Ancient Calendar, (c. 1579) (Heyden, xxviii). He was fluent in Nahuatl, the Aztec language, and was therefore able to consult natives as well as pictorial codices as well as work done by earlier friars. His empathetic nature allowed him to gain the confidence of many native people who would not share their stories with Europeans, and was able to document many previously unknown folktales and legends that make his work unique.
