Isn't this always something you wanted to know? And what is really hilarious, is I was wondering specifically when my heart was gonna be ripped out; and when I told my flat mate, 'it' replied, "The universe is answering questions now."

Sacrificial rituals featuring human heart extraction were a prevalent religious practice throughout ancient Mesoamerican societies. Intended as a means of appeasing and honoring certain deities, sacrifices served as acts of power and intimidation as well as demonstrations of devotion and gratitude. Human sacrifices were highly structured, complex rituals performed by elite members of society, and the ceremonies included a myriad of procedures imbued with symbolic significance.

The specific techniques performed, the instrumentation utilized, and the underlying mythology motivating sacrifices varied across civilizations. Given the diversity of sacrificial rituals throughout Mesoamerica, Vera Tiesler and Guilhem Olivier assert an interdisciplinary approach incorporating scientific and humanistic evidence is needed in order to gain more nuanced insights into the procedural elements and the religious implications of human sacrifice during the Classic and Postclassic periods.

In the study, “Open Chests and Broken Hearts: Ritual Sequences and Meanings of Human Heart Sacrifice in Mesoamerica,” published in Current Anthropology, Tiesler and Olivier conduct an anatomical analysis of skeletal evidence and compare it with systematically checked historical sources and over 200 instances of ceremonial heart extraction in codices. Focusing on the location of openings created in the chest to allow for the removal of a victim’s heart and blood, the authors examine the resulting fractures and marks in articulated skeletons to infer about the nature of the entry wound and the potential instrumentation used.
