It's an ill wind that blows nobody any good. The combination of land cleared of its rainforest for grazing and satellite survey have revealed a sophisticated pre-Columbian monument-building society in the upper Amazon Basin on the east side of the Andes. This hitherto unknown people constructed earthworks of precise geometric plan connected by straight orthogonal roads. Introducing us to this new civilisation, the authors show that the ‘geoglyph culture’ stretches over a region more than 250km across, and exploits both the floodplains and the uplands. They also suggest that we have so far seen no more than a tenth of it. Download full article (PDF File)
The gradual devastation of the Amazon—the felling of thousands of square miles of forest, the clear-cutting of the jungle—has produced, paradoxically, one of the greatest archeological discoveries: a vast and complex ancient civilization. In cleared-away areas of the upper Amazon basin, researchers, using satellite imagery, have recently pinpointed a vast network of monumental earthworks, including geometrically aligned roads and structures, constructed by a hitherto unknown civilization. According to a new report published in the journal Antiquity, the archeologist Martii Pärssinen and other scientists have documented more than two hundred and ten geometric structures, some of which may date as far back as the third century A.D. They are spread out over an area that spans more than two hundred and fifty kilometers, reaching all the way from northern Bolivia to the state of Amazonia in Brazil.
As I previously wrote about in The New Yorker and in my book “The Lost City of Z,” for centuries most people assumed that the Amazon was a primeval wilderness, a place in which there were, as Thomas Hobbes described the state of nature, “no Arts; no Letters; no Society; and which is worst of all, continual feare, and danger of violent death.” Although the early conquistadores had heard from the Indians about a fabulously rich Amazonian civilization, which they named El Dorado, the searches for it invariably ended in disaster. Thousands were wiped out by disease and starvation. And after a toll of death and suffering worthy of Joseph Conrad, most scholars concluded that El Dorado was no more than an illusion. Indeed, scientists believed that the merciless conditions in the jungle were simply too inhospitable to support a large population, which is a precursor to any sort of large, complex society. The most influential archeologist of the twentieth century, Betty Meggers, famously dubbed the region a “counterfeit paradise.”
In the early nineteen-hundreds, the British explorer Percy Harrison Fawcett challenged this prevailing notion. While exploring and mapping much of the same area where the ruins were recently discovered, he reported finding large earth mounds filled with ancient and brittle pottery. Buried under the jungle floor, he claimed, were also traces of causeways and roadways. Based on this and other evidence, he insisted that the Amazon once contained large populations and at least one, if not more, advanced civilizations. Despite being dismissed and ridiculed as a crank, he set off in 1925 to find the place, which he christened the “City of Z.” He and his party, including his twenty-one-year-old son, Jack, then vanished forever—a fate that seemed to confirm the madness of such a quest.
Over the past several years, however, there has been mounting evidence that nearly everything that was once generally believed about the Amazon and its people was wrong, and that Fawcett was in fact prescient. When I followed Fawcett’s trail into the Xingu area of the Brazilian Amazon, in 2005, I met up with the archeologist Michael Heckenberger. In the very area where Fawcett believed he would find the City of Z, Heckenberger and his team of researchers had discovered more than twenty pre-Columbian settlements. These settlements, which were occupied roughly between 800 and 1600 A.D., included houses and moats and palisade walls. There were geometrically-aligned causeways and roads, and plazas laid out along cardinal points, from east to west. According to Heckenberger, each cluster of settlements contained anywhere from two thousand to five thousand people, which means that the larger communities were the size of many medieval European cities. “These people had a cultural aesthetic of monumentality,” Heckenberger told me. “They liked to have beautiful roads and plazas and bridges.”
The latest discovery proves that we are only at the outset of this archeological revolution—one that is exploding our perceptions about what the Amazon and the Americas looked like before the arrival of Christopher Columbus. Pärssinen and the other authors of the study in Antiquity write, “This hitherto unknown people constructed earthworks of precise geometric plan connected by straight orthogonal roads…. The earthworks are shaped as perfect circles, rectangles and composite figures sculpted in the clay rich soils of Amazonia.” The archeologists say they still don’t know if these earthworks, which are made of trenches thirty-six feet wide and ten feet deep, with adjacent walls up to three feet high, were designed for defensive purposes or for ceremonial works. Because of the symmetrical shape of many of the mounds and the way they slant to the north, there is some speculation that they may have had an astronomical purpose.
What is striking about the structures is that their monumentality and sophisticated design are best seen from an aerial view, where they look like an elaborate geometry equation diagrammed in the earth. Pärssinen and the team of scientists estimate that the population at these sites may have been as large as sixty thousand people, and what’s more that the sites found so far represent a fraction of what exists—”only ten percent of what is actually there.” The disappearance of this still mysterious civilization correlates with the arrival of the conquistadores in the Amazon and the spread of diseases. Alas, the discovery of this glorious civilization is due to another tragedy—the vanishing of the once great jungles its people inhabited. http://www.newyorker.com/online/blogs/newsdesk/2010/01/the-city-of-z.html
