The Pyramid of the Sun at Teotihuacan.
Located about 30 miles (50 kilometers) northeast of modern-day Mexico City, Teotihuacan was one of the largest urban centers in the ancient world. No one knows who built it. The city flourished between 2,100 years ago, when construction began, and about 1,400 years ago, when it went into a period of decline, including a fire that caused great damage. However, even with the decline, the city was never truly “lost” — the Aztecs made regular pilgrimages to the site in later periods.
What the city’s own inhabitants called the city and its structures is unknown. The current name, Teotihuacan, was given to it by the Aztecs and means “the place where the gods were created.”
Size and influence
At its zenith, Teotihuacan encompassed an urban core of about 8 square miles (20 square km) with a population estimated at more than 100,000 people. Its influence was felt throughout central Mexico and as far south as Guatemala.
Avenue of the Dead
Running on a north-south axis is the city’s main street known today as the Avenue of the Dead, from a later Aztec name. It runs for more than two miles and contains three major pyramid complexes.
Pyramid of the Moon
At the northern end of the avenue is the Pyramid of the Moon, from an Aztec name. Recent research suggests it was built in stages between around 1 AD and 350 AD. It started off as a small platform and eventually became a 150-foot-high (46 meters) pyramid with a base 550 feet (168 meters) by 490 feet (149 meters). Its elevated platforms were likely used for rituals that could be witnessed by people on the ground. Tombs found associated with the structure contain both human and animal sacrifices along with grave goods such as obsidian and greenstone.
Pyramid of the Sun
Less than half a mile south of the Pyramid of the Moon is the Pyramid of Sun. At a height of more than 200 feet (63 meters) and a base more than 730 feet (225 meters) long on each side, this pyramid is one of the largest structures created in the pre-Columbian New World. It would have been completed around 200 AD.
In 1971, an archaeological team discovered a tunnel underneath the pyramid, its entrance located near the Avenue of the Dead. They dug out the fill in the tunnel finding that it terminated in a cloverleaf shaped chamber which, sadly, had been looted in antiquity. The cave was likely used for rituals of some kind.
Another discovery, announced late last year, was a small treasure trove of offerings that may date to when construction of the pyramid began. Among the items found was a green serpentine mask that may have been a portrait of an ancient individual.
Temple of the Feathered Serpent
Located south of the Pyramid of the Sun is the Temple of the Feathered Serpent, also known as “La Ciudadela,” a name Spanish conquistadors gave it. The focal point of this monument is a six-stepped pyramid, smaller than the other two examples on the Avenue of the Dead. Two apartment compounds located nearby may have been inhabited by local elites.
The pyramid is believed to have been completed sometime in the 3rd century AD. Cut in low relief on the structure are alternating heads showing Quetzalcoatl, a feathered serpent god, and a being that appears to be Tlaloc, an ancient storm god.
Found near the pyramid are the burials of about 200 people. Many of them were young men and the grave offerings suggest that they were warriors, possibly Teotihuacan’s own. The fact that many of them were found with their wrists crossed behind their backs suggests that they had been tied up and, for some reason, sacrificed. Young women and a few older men were also found, with offerings.
Teotihuacan is well-known for its colorful murals painted on plastered walls. They can be found in the city’s many apartment compounds as well as on other buildings identified as palaces and temples. Among the motifs that can been seen are images of the storm god, Tlaloc, as well as a deity that scholars call the “Great Goddess,” likely associated with agricultural fertility. Other motifs include birds, jaguars, coyotes, owls and the feathered serpent.
Whether pictographic figures found at Teotihuacan constituted a proper writing system is a source of debate. Karl Taube, a professor at University of California Riverside, argues in a paper that the inhabitants “had a complex system of hieroglyphic writing,” one complementing the vast and ancient city.
