Final answer:
The question pertains to Yaxchilán, an archeological site in Chiapas, Mexico. However, the provided details mainly describe Chichen Itza, another Maya civilization site, famous for its Temple of Kukulcán, El Castillo, which exhibits advanced Mayan architecture and astronomical knowledge.
Step-by-step explanation:
The student's question refers to Yaxchilán, a significant archeological site in Chiapas, Mexico, which is evidence of the ancient Maya civilization. While Yaxchilán is indeed an important site, the information provided relates to another prominent Mayan site, Chichen Itza, which was a major center of the Mayan civilization from the 9th to 13th centuries CE. Among Chichen Itza's most iconic structures is El Castillo, or the Temple of Kukulcán, a pyramid that showcases the Mayans' architectural genius and astronomical knowledge.
Mayan Architecture is renowned for its intricacy and functionality, with El Castillo serving as a prime example. The pyramid's design integrates a calendar system, with each of its four sides featuring ninety-one steps; when including the top platform, the total stair count equals 365, the number of days in a solar year. This architectural marvel also plays host to an astronomical phenomenon during the equinoxes, where the play of light and shadow creates the illusion of a serpent descending the pyramid, coinciding with representations of Kukulcán, the feathered serpent deity.
In addition to El Castillo, Chichen Itza is home to El Caracol, an observatory that further emphasizes the Mayas' sophisticated understanding of astronomy and their ability to incorporate it into their architecture. Similar to Yaxchilán, Chichen Itza was constructed using limestone, which was readily available in the Yucatan Peninsula. The Mayans also utilized advanced techniques such as stereotomy to precisely shape the limestone without the use of mortar, allowing for the elaborate engraving of images and symbols significant to their culture, such as the battles and the representations of Quetzalcoatl on El Castillo.
