At the time of the conquest of Mexico, the anonymous authors of the Anales de Tlatelolco (1560s) recorded the deaths of two Mexica ritual specialists. During the tumultuous events of the times, Quauhnochtli (a telpochcalli specialist) and Quauhcoatl (a calmecac specialist) died protecting the temple of Huitzilopochtli and his bundled embodiement in the neighborhood of Huitznahuac. 
Scholar Josefrayn Sánchez-Perry reconstructs the lives and labors of the two specialists, articulated through Nahuatl-language texts, material culture from neighborhood and temple spaces, and the academic study of religion. The book expands on known theories on Mexica ritual specialists by providing new insights about telpochcalli and calmecac duties, their interrelated educational models, and the collective practices that brought people, animals, flora, specialists, and teteo (more-than-human forces) together. The book demonstrates that telpochcalli and calmecac specialists shared the ritual responsibilities of collective and elective practices.
Giving care to teteo, giving life, and giving offerings were balanced with giving war, giving council, and giving music and dance. As Quauhnochtli and Quauhcoatl ensured the safety of the bundled Huitzilopochtli, they characterized how a Mexica ritual specialist lived and what they did.
