Abstract: Decoding the Astronomical Narrative in the Codex Borgia
Lecturer: Susan Milbrath
The Codex Borgia, one of the great masterpieces of ancient Mexico, contains a unique narrative section that has been studied for more than a century. Using modern computer simulations of astronomical events, I have proposed a definitive reading of the narrative. The colorful images displayed over 18 page sequence link the cycle of ceremonies of the Central Mexican calendar to specific astronomical observations, including Venus events and lunar cycles, and the only total eclipse of the sun witnessed in Central Mexico during the Late Postclassic period (AD 1325-1520).
