Residential patterns of Mexica human sacrifices at Mexico-Tenochtitlan and Mexico-Tlatelolco: Evidence from phosphate oxygen isotopes

This is the first systematic study of residential patterns of Mexica human sacrifices, as determined from bone and enamel phosphate oxygen isotope data of individuals recovered at the Templo Mayor of Tenochtitlan (n = 36) and the Templo R of Tlatelolco (n = 24). We identify these individuals' geographic residences and compare these patterns with phosphate oxygen isotope data from a contemporary non-sacrificial group (Ecatepec; n = 24) from the Basin of Mexico. The sacrifices' residential patterns are evaluated to assess their group membership (i.e., as locals, long-term residents, or non-locals from other regions of Mesoamerica). The Tlatelolco subadult and adult sacrifices were either locals or long-term residents. The Templo Mayor subadult sacrifices offered at several ceremonies were non-locals and long-term residents, while the adult sacrifices were long-term residents (e.g., slaves living in Tenochtitlan >10 yrs.) or non-locals (e.g., war captives, slaves, spoils-of-war sacrificed soon after arriving to the Basin). Our results demonstrate the Templo Mayor priests had broad access to long-term residents and non-locals with origins from Mesoamerican regions subjugated by the Mexica. This study illustrates the Mexica obtained individuals for sacrifice with a diverse range of physical, social, and geographic characteristics for their ritual ceremonies.

Automated summary

The study found that the sacrifices at Tlatelolco were mostly locals or long-term residents, while the sacrifices at Templo Mayor were mostly non-locals and long-term residents for subadults, and long-term residents or non-locals for adults. This suggests that the Templo Mayor priests had access to a diverse range of individuals for sacrifice with different origins.
