| Summary: | In the territorial limits of the towns of Santa Cruz Acalpixca and San Bartolomé Xicomulco, the place of Tenene en Piedra Larga is located on the mountain of Xochimilco. In front of this place you can see an extensive archaeological site where there is a miniature replica of the landscape with carvings of agricultural terraces, little pools and small channels. From this monolith the solar output is observed on December 21 in the middle of the winter solstice and during March and September, the astronomical equinoxes. In this calendar horizon other important dates are recorded for the indigenous world, such as the beginning of the year, so a very precise calendar of 365 days and another of 260 days can be built and has the potential to allow accounting based on thirteen, novenas, septimas, which is the basis of the ancient calendars and which were applied in the planning of the agricultural and religious activities of the Xochimilca community. Objective: Study how many days the Sun at its exit apparently touches the crater of the Popocatépetl volcano seen from the Long Stone marker. Methodology: Direct observation of the phenomenon from the Piedra Larga monolith from December 13 to 21 (winter solstice). Results: The Sun remains 18 days in the Popocatépetl crater, a multiple of 9, and 7 and 13 were found in the calendrical horizon reading. |
