Tlahuizcalpantecuhtli
Lord of the dawn
What it rules
Venus as morning star, the light that announces.
Why «energy» and not «god»
Because «god» translates badly. The Mexica did not separate the deity from the force it stands for in the way the European word does, and calling them gods imports an idea that is not theirs. «Energy» is not perfect either, but it does not carry that freight. It is a decision of this site, and it is declared as one.
The full entry is in Spanish, and here is why
What you have read above is this project's own summary of Tlahuizcalpantecuhtli. The full entry — the part that rests on the sixteenth-century sources — has not been translated, and that is a decision rather than an omission.
We chose not to touch the primary text. Those sections quote Sahagún, Durán and the codices in their own words, often in sixteenth-century Castilian. A quotation carried across stops being a quotation: it loses the register, the ambiguity and the exact wording someone might want to check against a facsimile.
In Spanish the entry carries:
- El nombre
- La luz que también hiere
- Duodécimo del día
- De dónde viene su imagen

The name
Tlahuizcalpantecuhtli is «the lord at dawn»: the personification of the morning star, the planet Venus in its appearance before the sun. He is therefore understood as a manifestation of Quetzalcoatl, and pairs with Xolotl, who is that same planet as the evening star.
Where its image comes from
The images in this app are drawn for it, not traced. Below is what the sources say about his appearance, feature by feature. What they do not say is left blank: a declared gap is better than an invented feature.
