A BRIEF HISTORY OF MEXICO
26
With extra crops and goods, the Olmec set about spending their sur-
pluses. They traded their crops and rubber balls for central highland
obsidian to make tools and southeastern lowland green-blue jade to cre-
ate magnificently polished objects. They exchanged their magnificently
carved ornaments and worked shells for Oaxacan iron-ores in order to
make polished mirrors—mirrors known to be used later in Mesoamerica
by shamans and rulers for communicating with the gods and ancestors.
At home, the Olmecs constructed the first monumental buildings.
The buildings were earthen, not stone like later cities, but while other
areas of Mesoamerica were mere villages of wattle and daub (interwo-
ven poles plastered with clay), the Olmecs of San Lorenzo (1200–900
b.c.e.) reconstructed a natural salt mound into an immense plateau,
3,000 feet long and almost 2,000 feet wide. On top were 200 earthen
mounds for residences and ceremonial buildings and an elaborate drain-
age system connecting artificial ponds. At La Venta (900–400
b.c.e.),
the local population, numbering 18,000, constructed a great pyramid,
100 feet high. Here they buried, perhaps as offerings to the Underworld
gods, immense deity masks (16.5 × 20 feet), stone mosaics, and colored
clays, 3,022 pieces of precious polished jade and, in one burial alone,
1,000 tons of serpentine stone imported from the Pacific coast!
The Olmec built their great centers and carved their delicate bas
reliefs with the stone age kit that would persist until the Spanish con-
quest. What they undertook with such limited technology is often
astonishing. The nearest basalt to San Lorenzo was 30 miles away and
from La Venta, 80 miles. Yet vast quantities of this stone were imported
for carving colossal heads of rulers and 50-ton thrones showing their
divine descent. The stone had to be cut without metal (probably
rope-and-water abrasion assisted by drilling) and transported without
wheeled cart or pack animal. Most likely the basalt was dragged to a
river then floated on rafts to the centers. Some estimate these monu-
mental stones required crews of 1,000 people to move them.
It remains unknown why the Olmec civilization ended. Their hall-
mark art style—jade bas-reliefs of snarling jaguar-human figures (prob-
ably part of a shamanistic cult) and more portrait-like freestanding
sculptures of rulers with slanting eyes, flaring noses, and thick lips—
gradually disappeared. The monolithic sculptures were ritually muti-
lated, then carefully buried. Olmec political centers were abandoned
one by one. The power centers of Mesoamerica shifted elsewhere.
But the Olmecs left a legacy. Their trade into Honduras and across
Mexico to the Pacific coast, and the spread of their art and ideas,
geographically
defined
Mesoamerica. Olmec trade stimulated the devel-
