Book excerpt: Davíd Carrasco draws from the perspectives of the history of religions, anthropology, and urban ecology to explore the nature of the complex symbolic form of Quetzalcoatl in the organization, legitimation, and subversion of a large segment of the Mexican urban tradition. His new Preface addresses this tradition in the light of the Columbian quincentennial. "This book, rich in ideas, constituting a novel approach . . . represents a stimulating and provocative contribution to Mesoamerican studies. . . . Recommended to all serious students of the New World's most advanced indigenous civilization."—H. B. Nicholson, Man
