Codex Borbonicus

An Aztec pictorial manuscript painted on a single continuous sheet of amatl bark paper some 14.2 metres long, made in the Valley of Mexico around the time of the Spanish conquest, probably close to the year 1507. It opens with a tonalamatl, a divinatory calendar of twenty trecena periods of thirteen days each, every page centred on the deity who rules that period, and continues with a section on the eighteen veintena festivals of the solar year and a panel marking the 52 year calendar cycle. On its 52 year cycle panel, the deities Quetzalcoatl and Tezcatlipoca are shown dancing together, Quetzalcoatl identified by his cut shell breastplate, conical headgear and hook shaped earrings, shown here in his wind god aspect Ehecatl with a beak like mouth mask. Its veintena section gives unusual prominence to the rain god Tlaloc in its image of the Huey Tozoztli spring festival, a departure from the more common veneration of the maize goddess at that festival. The manuscript is held by the Bibliotheque de l'Assemblee Nationale in Paris and, as a French national treasure, has not been permitted to leave the country since the 1960s.
