In Topiltzin Quetzalcoatl, H.B. Nicholson presents the most comprehensive survey and discussion of the primary sources and relevant archaeological evidence concerning this man/god, the most enigmatic figure of ancient Mesoamerica. Long available only on university microfilm, this classic text has been updated and now includes new illustrations and an index. Nicholson sorts through the wealth of material, classifying, summarizing, and analyzing all known primary accounts in the Spanish, Nahuatl, and Mayan languages of the career of Topiltzin Quetzalcoatl. In a new Introduction, he updates the original source material presently available to scholars concerned with this figure.
