The Temple of the Feathered Serpent is the third largest pyramid at Teotihuacan, a pre-Columbian site in central Mexico (the term Teotihuacan, or Teotihuacano, is also used for the whole civilization and cultural complex associated with the site). This structure is notable partly due to the discovery in the 1980s of more than a hundred possibly sacrificial victims found buried beneath the structure. The burials, like the structure, are dated to between 150 and 200 CE. The pyramid takes its name from representations of the Mesoamerican "feathered serpent" deity which covered its sides. These are some of the earliest-known representations of the feathered serpent, often identified with the much-later Aztec god Quetzalcoatl. "Temple of the Feathered Serpent" is the modern-day name for the structure; it is also known as the Temple of Quetzalcoatl and the Feathered Serpent Pyramid.
Location
The Temple of the Feathered Serpent is located at the southern end of the Avenue of the Dead, Teotihuacan's main thoroughfare, within the Ciudadela complex. The Ciudadela (Spanish, "citadel") is a structure with high walls and a large courtyard surrounding the temple. The Ciudadela’s courtyard is massive enough that it could house the entire adult population of Teotihuacán within its walls, which was estimated to be one hundred thousand people at its peak. Within the Ciudadela there are several monumental structures, including the temple, two mansions north and south of the temple, and the Adosada platform. Built in the 4th century, the Adosada platform is located just in front (west) of the Temple of the Feathered Serpent, obscuring its view.
Architecture
The Feathered Serpent Pyramid is a six-level step pyramid built in the talud-tablero style. The outside edges of each level are decorated with feathered serpent heads alternating with those of another snake-like creature, often identified as Tlaloc. Nevertheless, Mary Ellen Miller and Karl Taube claim that these heads may represent a "war serpent", while Michael D. Coe claims, somewhat similarly, that they probably represent the "fire serpent" wearing a headdress with the Teotihuacan symbol for war. In the eyes of these figures there is a spot for obsidian glass to be put in, so when the light hits, its eyes would glimmer. In antiquity the entire pyramid was painted – the background here was blue with carved sea shells providing decoration. Under each row of heads are bas-reliefs of the full feathered serpent, in profile, also associated with water symbols. These and other designs and architectural elements are more than merely decorative, suggesting "strong ideological significance", although there is no consensus just what that significance is. Some interpret the pyramid's iconography as cosmological in scope – a myth of the origin of time or of creation – or as calendrical in nature. Others find symbols of rulership, or war and the military.
Today the pyramid is largely hidden by the Adosada platform hinting at a political restructuring of Teotihuacan during the fourth century CE, perhaps a "rejection of autocratic rule" in favour of a collective leadership. Following excavations in the early 20th century, a section of a façade on the monument's west side was discovered. This section is believed to date from the late 3rd century. Fantastic and rare carvings on the surfaces show depictions of the feathered serpent deity, other gods, and seashells on panels on either side of a staircase.
Condition and conservation
Since the structure has been exposed to the elements for the entire duration of its history, rain and groundwater, crystallization of soluble salts on the surface, erosion, and biological growth have caused deterioration and loss of stone on the surface. Tourist visitation also accelerated the deterioration. In 2004, the Temple of Quetzalcoatl was listed in the 2004 World Monuments Watch by the World Monuments Fund. The organization provided assistance for conservation in cooperation with the Instituto Nacional de Antropología e Historia and with help from American Express.
