About the wheel
Why it is a single stone, and what runs through its channels
What it covers
How the app's calendar wheel is built and why it is one piece rather than several rings turning independently.
The full entry is in Spanish, and here is why
What you have read above is this project's own summary of about the wheel. 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:
- Una sola piedra
- Las siete puertas
- El líquido azul
