The Maya Calendar and Astronomy

Why this matters

Predicting an eclipse with nothing but naked-eye observation is not guesswork, and the Dresden Codex records Maya astronomers doing exactly that: tracking Venus and eclipses precisely enough to put the results in writing centuries before modern instruments.

Daniel Brinton's 1882 translation turns colonial-era Maya writing into English, and that is a different thing from a pre-Columbian codex like the Dresden, made by Maya scribes with no colonial hand involved. Asking students to notice which category of source they are reading is what keeps them from treating any old-looking text as equally reliable.

From one teacher to another

I built this one to fix a myth I still hear from students every year, so the whole lesson leads to it. The guided notes lay out how the Maya ran two calendars at once - the 260-day Tzolk'in and the 365-day Haab' - meshing into the 52-year Calendar Round, plus the Long Count and the zero placeholder that let them track exact dates across thousands of years. The primary source is a real excerpt from the Books of Chilam Balam, a colonial-era Maya text, and I make students source it carefully: who wrote it, who translated it, and why it isn't the same thing as an ancient codex. The reading itself says time moves in a circle and that "when the count is finished it begins again" - which is exactly the evidence students use to explain why December 2012 was a cycle turning over, not a prophecy of the end of the world. Guided notes, activity, quiz, and exit ticket all come with answer keys, along with a teacher guide.
