The cycles of the sky
What the Maya counted, and how far it reaches
What it covers
The Venus, eclipse and Mars tables of the Dresden Codex, with their figures, and how they relate to the 260-day count.
The full entry is in Spanish, and here is why
What you have read above is this project's own summary of the cycles of the sky. 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:
- De dónde vienen
- Marte, tres vueltas justas
- Venus, el mismo número por otro camino
- Venus, a simple vista
- Los eclipses, cuarenta y seis vueltas
- Hasta dónde alcanzan
- Donde se rompe
