Abstract
An artificial structure was discovered under a natural skylight inside Grutas de Tzinacamóztoc, in the vicinity of the archaeological site of Cantona. The structure is made up of piled rocks, defining a pentagonal enclosure with a central mound. Detailed measurements and computer modeling allowed tracing of the sunbeam path projected on the structure and on the cave floor, particularly for dates of astronomical and/or Mesoamerican calendrical importance. This corroborates the possible prehispanic use of this site as a complex and sophisticated gnomon.
Se descubrió una estructura artificial bajo un tragaluz natural en las Grutas de Tzinacamóztoc, cerca del sitio arqueológico de Cantona. La estructura consiste en un apilamiento de rocas que define un recinto pentagonal con un montículo central. Mediante medidas detalladas y modelación por computadora se pudo obtener la traza del haz de luz proyectada sobre la estructura y el piso de la cueva, en particular para fechas de importancia astronómica y/o calendárica ritual mesoamericana, corroborando el posible uso prehispánico de este sitio como un complejo y sofisticado gnomon.
