I knew I’d come across images of autosacrifice in the codices before! I’ve included two below so you can see how the Aztecs depicted themselves performing ritual bloodletting to benefit the gods.

The image above is taken from the Codex Telleriano-Remensis, a Post-Conquest religious text painted by Aztec artists in a style that is a hybrid of Mexican and European art. The worshipper is piercing his tongue and letting the blood flow as a gift to the Teteo. The tool in his hand looks like a pointed stick, rather than a thorn, bone perforator, or obsidian shard, so I believe this painting may be depicting the practice of “drawing straws through the flesh” I mentioned in my article on traditional forms of autosacrifice. If anyone’s got more information on this particular image, I’m all ears.

This second image comes from the Codex Magliabecchiano, another Post-Conquest codex drawn in a European-influenced style and speaking of religious subjects. This picture shows a group of worshippers doing many different forms of autosacrifice. One is piercing his tongue, while the other is piercing his ear. The green coloration of the objects they’re using to bloodlet makes me wonder if they’re either exaggerated maguey thorns or perforators made of jade. Given the traditional use of maguey thorns for this purpose and the association of jade with blood (as both are exceedingly precious), I could go either way. Again, if anyone knows more, please drop me a comment.
Additionally, we can see that these two worshippers have already completed more rounds of bloodletting than the forms they’re in the middle of in the picture. See the blood on their arms and legs? They’ve either been piercing in those places, or have nicked themselves with shards of obsidian or flint. Incidentally, the bag-like objects slung over their arms are traditional incense pouches. They were often made with paper and beautifully decorated, and would be filled with copal resin to be burned for the gods.
Today I’m going to give a quick overview of the types of autosacrifice performed by the Aztecs during the days of the Empire in order shed some additional light on this very important religious practice.
Traditionally, the Aztecs would collect blood from their ears, lower legs (calf, shin, or just above the ankle), lip, tongue, or penis. The tools and methods used would vary depending on the worshipper’s preferences, the ritual context, and in at least some cases, the instruction of a priest. The Florentine Codex records the rite of confession to Tlazolteotl, and according to Sahagun, the confessor priest would prescribe required penances to atone for the disclosed sins — these penances often included various forms of bloodletting.
The most common methods of getting the blood were by pricking the flesh with a sharp instrument. Maguey (agave) spines are the tool most frequently mentioned in the historical texts, though slivers of obsidian and special perforators made from a spike-shaped piece of sharpened bone were also used. (Incidentally, Quetzalcoatl, the First Priest, is often shown in the codices holding a bone perforator or two.) From what I’ve read, it seems that maguey spines were particularly associated with piercing the ears and the legs, probably because their large size would be sufficient to draw blood from the legs. The individual would pierce himself or herself in the chosen location, and once the thorns were sufficiently bloodied, would carefully arrange them on a bed of cut fir boughs, or stick them into a ball of dried grass.
Alternatively, the Aztecs would nick their earlobes with an obsidian knife, and the blood would be allowed to drip on the ground, be sprinkled into a fire, or flicked towards the sun, symbolically giving the life-energy to Tonatiuh.
Finally, there was a final type of personal blood offering, that of passing straws or cords through the body. This rather severe form of autosacrifice was a multi-step process. The person would first select a place to pierce. In the texts I’ve read, the tongue seems to be the most common choice for this kind, though the ears, legs, and possibly penis were used as well. (I haven’t the slightest idea of how that last one worked, it’s definitely not something the Spanish friars would’ve recorded the details of!) Then they would poke a hole with a sharp sliver of obsidian, and pull a number of straws or thin cords through the hole. This sacrifice was typically done in a temple or at the side of the road. Wherever it was done, the bloodied straws were left behind as offerings. Interestingly, this practice was apparently only done on days that had a proper sign according to the ritual calendar (tonalpohualli), but I’ve never come across what daysigns those were. Finally, this practice of drawing straws is usually listed as a priestly activity, not something done by ordinary people, though occasionally the nobility appear to have done it as well. Priests who did this often were obvious, as their tongues would be extremely scarred, damaged to the point where they were said to have had difficulty in speaking.
