The temazcal is one of the oldest and most persistent practices in Mesoamerica. Its use is documented from the Preclassic period and continues to the present in indigenous communities in Mexico and Central America, making it one of the most remarkable elements of cultural continuity in the region. It was a space of transition, purification, and renewal. The mouth with its double row of teeth and flames on the facade of the building depicted in this mural, and the stepped merlons above the roof, draw on the architectural vocabulary of temples—suggesting the temazcal was not an ordinary domestic space but a place of ritual practice. Its possible representation on the walls of Tetitla would indicate that it formed part of life within the complex.
