Symbolic representation of the months and day of the Aztec year with explanatory text in Nahuatl language transcribed into European script. At top left of the interior circle is a depiction of Hernando decor [Hernán Cortés?] wearing a black Spanish hat seated on a blue circle [the Lake of Mexico?]. At top right is Don Antonio Pimentel [son of Ixtlilxochitl, an ally of Cortes, and last native king of Texcoco] seated on a representation of a mountain [the Sierras of Acolhuan]. In the middle is an image of Nezahualcoyotl [the king of Acolhuan], and Itzcoatl [his ally, the Aztec emperor] who were allies in the mid-fifteenth century. Each is enthroned with his symbol in front of him. At bottom, are depictions of ancient Chichimecas, founders of the Texcoco empire, or native Americans, who sit before a sacrificial fire which rises to the sun (see facsimile, 30891-2).
The Boban Calendar, named after Eugène Boban, a French archeologist and collector, was brought to general attention in 1866 when Colonel Doutrelaine published a reproduction and explanation of the calendar in Archives de la commission scientifique de Mexique, Paris, 1866-1867, vol. 3, p. 120-133. Because of deterioration, the reproduction made in 1866 shows much greater detail than the original. The names of the months are written in Nahuatl (but with Castilian characters); the months are given different symbols than are usually present on other Aztec calendars.
