Tonalli
Day-sign heat · birth calendar force
Tonalli is the day-linked life-heat and animating force that receives a person's calendrical sign in Nahua thought. It is placed at the crown here to preserve the distinction from the six day-sign zones below; this point repeats the force vocabulary only so the calendar and anthropology can be read together.

Sources
Bernardino de Sahagún, Florentine Codex (primary_canonical)
Book IV, The Divinatory Art, documents the day-sign count and the birth-day reading that gives a person a calendrical tonalli; the crown coordinate is supported by separate Nahua body testimony rather than Book IV alone.
Alfredo López Austin, The Human Body and Ideology (scholarly_modern)
The modern analysis distinguishes tonalli as a Nahua animating entity associated with heat, day, and head; this point is a normalized front-view rendering of that reconstruction.
