As a result of the deforestation of the Amazon basin, a startling discovery has been made. Hidden from view for centuries, the vast archaeological remains of an unknown, ancient civilization have been found.

A study published in Antiquity, a British archaeological journal, details how satellite imagery was used to discern the footprint of the buildings and roads of a settlement, located in what is now Brazil and believed to span a region of more than 150 miles across.

�

As Brazilian rain forest has been cleared away to make way for animal grazing,

the architectural footprint of a network of ancient villages has been revealed.

�

"The combination of land cleared of its rain forest 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," the researchers wrote in the journal.

David Grann, author of the book "The Lost City of Z," points out that the existence of the ruins overturns the previously held belief that this portion of the Amazon basin had always been a pristine wilderness, even though legends of a lost Amazonian city still lingered by the time the Spanish arrived on the continent.

"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," Grann wrote on The New Yorker's Web site. (below report)

�

"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."

According to Martti Parssinen, Denise Schaan and Alceu Ranzi, the authors of the study, the community likely had a population of more than 60,000 people.

�

The researchers said they have only uncovered roughly 10 percent of the existing structures, which may date as far back as A.D. 800.

The discovery of the ruins of an ancient civilization in the upper Amazon basin

overturns previously held beliefs that the area had always been uninhabited.
�

�

As Grann describes in his book, British explorer Percy Harrison Fawcett claimed he had found evidence of an ancient civilization, which he called the City of Z, in the same area.

�

He disappeared in the jungle on a 1925 expedition undertaken with his son and a companion.

While isolated discoveries of pottery and road beds had been made over the past few decades, the clear cutting of the Amazon forest laid bare the scope of the archaeological site.

Under the Jungle

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 P�rssinen 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.

�

P�rssinen 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. P�rssinen 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.
