Tlazolteotl did not originate with the Aztecs. She came from the Huastec people of the Gulf Coast and was absorbed into the Aztec pantheon when the Triple Alliance subjugated the Huasteca around 1450.
The Aztecs reshaped her but preserved her essential contradiction: she was simultaneously the goddess who incited sexual transgression and the goddess who consumed it.
The same deity who led people into sin was the only one who could take it back.
Her most important epithet was Tlaelquani, meaning eater of filth, a title that described her ritual function precisely.
In Aztec theology, tlazolli referred not just to physical waste but to moral and sexual pollution.
These were understood as the same category of substance, a contamination of the body and spirit that accumulated through misconduct and could make a person sick, unlucky, or spiritually dangerous to those around them.
The solution was confession through her priests, who acted as intermediaries between the penitent and the goddess.
This confession could only happen once in a lifetime.
The timing was strategic: most people waited until old age or approached death before making it, calculating that a single use of such a powerful absolution should cover the maximum possible accumulation of sin.
The penitent named every transgression. Tlazolteotl ate it. The soul was clean.
She also governed steam baths, midwifery, weaving, and childbirth, all domains connected to the threshold between the body’s interior and the world outside it.
Bernardino de Sahagún documented her cult extensively in the Florentine Codex, the 16th century encyclopedic account of Aztec religion he compiled from indigenous informants after the conquest.
