This compilation, produced both by Sahagún and indigenous aides, documents the convergence of Aztec and European cultures. As such it represents the hybrid nature of colonial culture and is best approached from an understanding of both its European and Aztec influences. It is the aim of this thesis to consider the Florentine Codex, and Book Eleven ("Earthly Things") specifically, in the context of the European bestiary tradition. This thesis will illuminate Sahagún's role as a Franciscan missionary and the ways in which he utilized Aztec animal imagery syncretically, for the purpose of evangelization. Analysis takes the form of case studies concerning the jaguar, birds, and serpents. / Committee in Charge: Dr. James Harper, Chair; Dr. Lauren Kilroy; Dr. Robert Haskett
