In 1957 Miguel Covarrubias published a now-famous diagram illustrating the evolution of Mesoamerican rain gods. Drawings of 20 faces from Pre-Columbian iconography were arranged in 4 columns and connected with arrows. Teotihuacano murals, Yucatec Maya stonework, and Aztec ceramics were all traced back to a carved Olmec celt.

But where Covarrubias’s visual chart is based on assumptions of (visual and conceptual) continuity, and on a single origin point (ursprung), Florescano’s discussion of “Quetzalcoatl” argues that this figure is “reborn...
