Taking the Measure of Mesoamerica.

The article focuses on the architectural and mathematical sophistication of Xochicalco, an ancient city-state in central Mexico, which emerged after the decline of Teotihuacan. Researchers have discovered that the builders of Xochicalco utilized two distinct units of measurement—zapal and maitl—originating from Maya and central Mexican traditions, respectively. This duality in measurement reflects a blend of cultural influences, as seen in the design of significant structures like the Pyramid of the Feathered Serpents, which incorporates symbolic references to both the Maya and central Mexican calendars. The findings suggest a complex interaction between these cultures during the Epiclassic period, highlighting the advanced planning and cultural amalgamation present in Xochicalco's architecture.
