The Continuum of Life in Codex Borbonicus

Extract:
"It seems best to present them [gods] with specific examples of Aztec iconographic representation, and to move in some instances out of the Quetzalcoatl family, in part to give the images a better and fuller context, in part to show them as the Aztecs saw them in their own writing system. This seems particularly important to me since I think it likely that the Aztecs made and kept religious books not so much as a means of remembering things they would otherwise have forgotten or of conveying new information, but to help make them unforgettable, to give them more tangible form, and to aid in internal visualization. All the iconographic images in this series come from a single work, Codex Borbonicus."
