the agricultural potential of the central basin. Teotihuacanos also
controlled vast quantities of precious obsidian, the glass “iron” from
which Mesoamerican tools were made and their major item of trade.
Teotihuacanos’ wealth paid for the Pyramid of the Sun, completed by
150
c.e., and covering about the same area as the Great Pyramid in
Egypt, but with only half its height. That great effort of human con-
struction was followed by others, including the Pyramid of the Moon
and a 48-acre administrative and market complex, larger than the
Pentagon in Arlington, Virginia (34 acres).
Yet for all of Teotihuacán’s recognized greatness, its rulers remain
anonymous: nowhere in the art of the city are their portraits discov-
ered, and nowhere on the monuments and great buildings were any
writings inscribed about their achievements. Yet their presence is felt
in every element of the city’s design. A rigid grid plan prevails for over
eight square miles. No natural feature was permitted to interfere with
the layout: the San Juan River was canalized to conform to the grid as it
passed through the city. Symmetry was the aesthetic mandate, from the
composition of paintings in palaces to the urban plan for the city.
The urban plan invaded even private homes. The population—who,
based on depopulation studies of the surrounding countryside, were
probably coerced into living in the city—resided in 2,000 apartment
complexes for 60 to 100 individuals each. These complexes could vie
with modern housing projects in the uniformity of their plan: one-story,
windowless buildings with rooms constructed around interlocking,
open courtyards. These complexes included a semipublic space for
worship, especially of the city’s patron, the Great Goddess, from whose
yellow hands flowed streams of jades and shells and other symbols of
fertility and wealth (
see page 25). Of course, the elite classes lived in
grander complexes decorated with bas relief sculptures and murals.
There were warrior enclaves as well as neighborhoods of potters and
obsidian workers. Archaeologists have identified foreign neighbor-
hoods, too: residences with cultural traces from the Zapotec, Gulf
coast, and Maya regions that may have housed traders and artisans.
Many aspects of life in Teotihuacán remain mysterious. Some
Mesoamericanists wonder whether the objects in the precious stream
flowing from the Great Goddess’s fingers are in fact signs that consti-
tute a form of writing. If not, then there is no writing known from this
great city despite the fact that the Teotihuacanos were exposed to the
hieroglyphs of other Mesoamerican cultures, such as the Maya. Could
they have consciously rejected literacy? Many believe records were
kept, but on perishable bark paper rather than stone. Because there is
