Bloodletting was the ritualized practice of self-cutting or piercing of an individual's body that served a number of ideological and cultural functions within ancient Mesoamerican societies, in particular the Maya. When performed by ruling elites, the act of bloodletting was crucial to the maintenance of sociocultural and political structure. Bound within the Mesoamerican belief systems, bloodletting was used as a tool to legitimize the ruling lineage's socio-political position and, when enacted, was important to the perceived well-being of a given society or settlement. Bloodletting was performed by piercing a soft body part, generally the tongue, and scattering the blood or collecting it on amate, which was subsequently burned. The act of burning the sacrificed blood symbolized the transferral of the offering to the gods via its transformation into the rising smoke. Piercing was accomplished using obsidian prismatic blades, stingray spines, or shark's teeth. Under some circumstances, a rope with attached thorns or obsidian flakes would be pulled through the tongue. Jade or stone spines and teeth have been found in the archaeological record. Some of these jade artifacts have rather dull points but might have been used once the initial cut was made, or might purely be ritualistic objects not used in actual bloodletting. The location of the bloodletting on the body often correlated with an intended result or a corresponding symbolic representation. For example, drawing blood from the genitals, especially the male sex organs, would be done with the intent of increasing or representing human fertility. Ritualized bloodletting was typically performed by elites, settlement leaders, and religious figures (e.g., shamans) within contexts visible to the public. The rituals were enacted on the summits of pyramids or on elevated platforms that were usually associated with broad and open plazas or courtyards (where the masses could congregate and view the bloodletting).
