Full moon extreme positions, lunar standstills and the metonic cycle at Cañada de la Virgen archaeological site
The purpose of this work is to show the extreme positions of the full moons of June, seen from the main entrance into the enclosed patio of Complex A at the archaeological site Cañada de la Virgen. These positions are discussed in terms of the cycles known as major and minor lunar standstills, as we...

The purpose of this work is to show the extreme positions of the full moons of June, seen from the main entrance into the enclosed patio of Complex A at the archaeological site Cañada de la Virgen. These positions are discussed in terms of the cycles known as major and minor lunar standstills, as well as the metonic cycle.Given the publication guidelines, an enormous effort of synthesis had to be made when dealing with the high number of astronomical events and dates that have been worked through the Permanent Program of Celestial Observations at Cañada de la Virgen. For the same reason, I had to limit possible comparative examples that would serve to justify the dates or “date families” detected in the site, with others studied in Mesoamerica.Nevertheless, the architectural, calendrical and symbolic implications of the pre-Hispanic cosmovision are revealed, as well as the intricate autochthonous astronomical features of the specific cultural region of El Bajío. On the other hand, although there are other examples that deal with the functionality of pyramidal structures acting as a hill or artificial horizon, only Rubén Morante (1996) is cited, since he coined such term while working at Teotihuacán in central México.The different lunar positions shown are intertwined with the rhythm of the sunset, emphasizing the moments when such celestial object rests on the different superimposed bodies of the pyramidal base. Particularly in the corners and slopes where these bodies intersect, creating numerical intervals that have certain qualities of multiplicity with recognizable Mesoamerican calendar units: 20, 13, 5, 52, 65, and so on. Actually, 65 is the interval that became evident as the exercise unfolded. The number appears in terms of years and tens of years, within cycles that could -eventually- be associated with the founding moment of the ceremonial center that concerns us, considering the dates of Carbon recovered by Gabriela Zepeda (2012). As coordinator of the exploration of Cañada de la Virgen, Zepeda emphasized the role of cultural astronomy as a complementary method to explain the foundational dates, along with the moments revealed as differentiated stages of occupation through construction system features1.The internal congruence of the presented model explains the importance of the major and minor lunar positions and discusses the appropriate terminology in terms of references to lunar standstills, lunistices or maximum and minimum extremes of full moon.1 Personal conversation with archaeologist Gabriela Zepeda. Susan Milbrath discussed the stages of occupation of Templo Mayor in terms of the 52 years of the new fire. |

El propósito de este trabajo es mostrar las posiciones de los extremos de lunas llenas de junio, vistas desde el acceso al patio cerrado del Complejo A de la zona arqueológica Cañada de la Virgen. Se discuten dichas posiciones en función de los ciclos conocidos como paradas lunares mayor y menor, así como del ciclo metónico.Dados los lineamientos de publicación, hubo de realizarse un enorme esfuerzo de síntesis al tratar el alto número de eventos astronómicos y de fechas que han sido trabajados a través del Programa Permanente de Observaciones Celestes de Cañada de la Virgen. Por la misma razón, hube de limitar posibles ejemplos comparativos que servirían para justificar las fechas o “familias de fechas” detectadas en el sitio, con otras estudiadas en Mesoamérica.Con todo, a lo largo del texto se van develando las implicaciones arquitectónicas, calendáricas y simbólicas de la cosmovisión prehispánica y el intrincado pensamiento autóctono propio de la región cultural del Bajío. Por otro lado, si bien existen otros ejemplos que tratan la funcionalidad de un basamento arqueológico fungiendo como cerro u horizonte artificial, aquí sólo citamos a Rubén Morante (1996), quien acuñó dicho término trabajándolo en Teotihuacán.Las diferentes posiciones lunares que se muestran, se entrelazan al ritmo de la puesta solar, enfatizando los momentos en que el astro descansa sobre los diferentes cuerpos superpuestos del basamento piramidal. Particularmente en la esquinas y taludes en donde dichos cuerpos se intersectan, creando así intervalos numéricos que tienen ciertas cualidades de multiplicidad con números calendáricos netamente mesoamericanos: 20,13, 5, 52, 65, etcétera.Finalmente, el intervalo que fue posible destacar a través del ejercicio realizado, corresponde al 65. En este caso, el número figura en términos de años y decenas de años, a partir de ciclos que podrían –eventualmente–, asociarse al momento fundacional del centro ceremonial que nos ocupa, considerando las fechas de Carbón recuperadas por Gabriela Zepeda (2012). Como coordinadora de la exploración de Cañada de la Virgen, la maestra Zepeda enfatizaba el papel de la astronomía cultural como método complementario en el entendimiento de las fechas fundacionales y los momentos que el sistema constructivo revela como etapas de ocupación diferenciadas1.La congruencia interna del modelo permite explicar también la importancia de las paradas lunares mayor y menor y discute la terminología adecuada en tanto las referencias a paradas lunares, lunisticios o extremos máximo y mínimos de luna llena.1 Conversación personal con la arqueóloga Gabriela Zepeda. Susan Milbrath discutió la etapas de ocupación de Templo Mayor en función de los 52 años del fuego nuevo.
