Mesoamerican Codices

The obverse of the manuscript has been interpreted as of a ritual-calendrical nature, but it also contains mythological genealogies with some emphasis on 9 Wind (Quetzalcoatl), lists of place glyphs and dates, and of persons, gods, or priests. Each of its 10 major sections repeats data pertaining to a ritual or ceremony in which a constant element is fire-making. The reverse presents a genealogy that begins two generations before the inception of the first Tilantongo dynasty and continues through the marriage of the third rulers of the third dynasty. This span corresponds to a period from the eighth century through the middle of the fourteenth century.
