Mitla architecture reveals ancient Zapotec measurement system

A new study by researchers from the National Autonomous University of Mexico (UNAM) has uncovered a sophisticated mathematical measurement system used by Zapotec architects in the ancient city of Mitla, Mexico.

The research indicates that the city's stone structures were designed using a fundamental unit of approximately eight centimeters, roughly the width of four fingers placed side by side. By multiplying this base unit, architects created larger structural dimensions, such as 1.84 and 1.92 meters, which appear frequently in the design of doors, columns, and courtyards across nine architectural complexes.

Previously, variations in building dimensions were interpreted as architectural irregularities. However, the study suggests these differences were intentional choices based on the function and symbolic significance of specific spaces. Most notably, the findings point to a connection between these architectural measurements and Mesoamerican calendar cycles, specifically the 52-year cycle where solar and ritual calendars align.
