In Aztec mythology, Tlahzolteōtl (or Classical Nahuatl: Tlâçolteotl, pronounced [t͡ɬaʔs̻oːɬˈteoːt͡ɬ]) is a deity of sex, sexuality, lust, sin, vice, impurity, purification, steam baths, and a patroness of adulterers.

[2][3][4] Tlazolteōtl is the deity for the 13th trecena of the sacred 260-day calendar Tōnalpōhualli, the one beginning with the day Ce Ōllin, or First Movement.

[11] The uncleanliness was considered both on a physical and moral level and could be cured by steam bath, a rite of purification, or calling upon the Tlazoltēteoh, the deities of love and desires.

[15] Tlazolteōtl was one of the primary Aztec deities celebrated in the festival of Ochpaniztli (meaning "sweeping") that was held September 2–21 to recognize the harvest season.

[17] In the film Raiders of the Lost Ark, the fictitious artifact, the Golden Idol is based on the actual Aztec Dumbarton Oaks birthing figure.
