Tonalamatl (Paperback)

High Quality Content by WIKIPEDIA articles! The tonalamatl is a divinatory almanac used in central Mexico in the decades, and perhaps centuries, leading up to the Spanish conquest. The word itself is Nahuatl in origin, meaning "pages of days."The tonalamatl was structured around the sacred 260-day year, the tonalpohualli. This 260-day year consisted of 20 trecena of 13 days each. Each page of a tonalamatl represented one trecena, and was adorned with a painting of that trecena's reigning deity and decorated with the 13 day-signs and 13 other glyphs. These day-signs and glyphs were used to cast horoscopes and discern the future.
