Ancient Cities in the Forest

Shining New Light on Old Legends


It has been said that we might not even recognize an alien life form should we encounter one, nor the ruins of an ali­en civilization (at least not on Mars, if NASA and JPL have their way). But how about ancient ruins here on Earth? Are we often looking in the wrong places and overlooking evidence of cultures that do not fit our preconceived no­tions? Can we even define “civilization”? There is reason to believe that the ruins of ice age “Atlantean” cultures may lie under water on the continental shelves, and the remnants of cultures that flourished during the Holocene Opti­mum may yet be found in areas that are today very arid or very cold.

Archaeologists always assumed that civilization began about 5,500 to 6,000 BP (before the present). First people developed agriculture, and then woven fabrics and fired ceramics, and began building towns of adobe brick or stone. Writing followed soon after. Aside from the fact that agriculture was developed by 12,000 B.P. at the latest, and the fact that the origins of the alphabet are a complete mystery, recent finds cast serious doubt on all of our assumptions.

Hunter-gatherers in Central Europe made woven fabrics and fired ceramics by 28,000 BP Other hunter-gatherers at the Gobekli Tepe site in what is now Turkey built large monuments of cut stone bearing at least some resemblance to Stonehenge and other stone circles and possibly indicating some knowledge of mathematics and astronomy. Our assumption that fabrics, ceramics, and shaped stone structures were possible only after the invention of farming is clearly mistaken.

We know of five ways for a people to obtain food. There are hunter-gatherers, fishermen (a variant of hunting), herdsmen, farmers (like many North American Indians a few centuries ago) who hunted for their animal protein, and farmers who also keep domestic livestock. It is now obvious that any of these systems can allow a civilization to devel­op; fishing during the last ice age could have supported quite a large population of seafarers.

Early Spanish explorers searched for lost cities like El Dorado in the rain forests of the vast Amazon river system. In 1541 Francisco de Orellana and Friar Gaspar de Carvajal went down the Amazon tributaries from the west and claimed to have seen huge walled cities, gleaming white, and roads up to sixty feet wide. But European diseases deci­mated the native population in what may have been the greatest epidemic in history, and later explorers and settlers found only “primitive” farmers in small villages, who hunted for their meat, rather like many of the Indians of North America. Yet the legends persisted.

Percy Fawcett, a colonel in the Royal Artillery and a veteran of World War One, was born in 1867 in Devon, Eng­land, to a rather adventurous family. His father was a Fellow in the Royal Geographic Society, and his brother Edward was a mountain climber. A man with intellectual interests (some would say obsessions), he believed that the ruins of Atlantis, or at least one of its colonies, might be found in the Brazilian rainforest. He made several expeditions, and, in 1925, he and his oldest son Jack went into the (then largely unexplored) Matto Grosso region in search of a lost city he called “Z.” They vanished off the face of the Earth and were apparently never seen again. They may have been murdered and robbed by the Kalapalos Indians, who admitted being the last to see them and who had some of their possessions, or by Indians further along on their route, like the Arunas, Suyas, or Xavantes. The Kalapalos claimed to have seen Fawcett’s nightly campfire smoke further in the distance each day for five days. This is certainly possible, as travel in dense jungle can be painfully slow. Supposedly, one member of the Kalapalos tribe admitted that they had murdered and robbed the Fawcett’s; and it is a fact that the tribe captured and robbed the members of an expedition in 1996, but they released them unharmed. There are other rumors that Fawcett and his son were captured by Indi­ans and lived among them for years, even marrying into the tribe, but there is no evidence of this.

Whatever happened to Fawcett and his son, we know that he was looking for a stone city in a region where there was little stone to be found, and practically none suitable for building. In the humid and rainy Amazon, structures of wood and thatch decay and adobe would be washed away, and whatever remained would be covered by the forest. Blinded by his own assumptions, Fawcett could have walked directly over the remains of an advanced culture and never seen or recognized it. Actually, in at least one part of the Amazon there is an ancient stone structure, the so-called “Amazon Stonehenge” in Brazil near the border with French Guiana, discovered by Brazil’s Amapa Institute of Scientific and Technological Research. It consists of 127 blocks of granite, many of them ten feet tall, and there is a hole in one that aligns with the sun at the time of the winter solstice. Ceramics nearby have been dated as early as 2,000 BP In the Andean foothills of southeast Peru, there are oddly symmetrical structures that may be the remains of cities and of pyramids rivaling in size those at Giza. Or they may be natural formations…no one yet is willing to fi­nance excavations in this relatively inaccessible area.

Regarding the “Stonehenge” and its associated pottery, there is no way to be certain that the circle and the ceram­ics were made by the same culture or at the same time, although it seems likely. There is really no way to date stone blocks. Ceramics and stones used in hearths and heated to a high enough temperature can be dated by thermolumi­nescence. Electrons are trapped in the crystal lattice of ceramics and are driven out when they are fired. Over the cen­turies, new electrons seep back in and can be measured by the dim light they emit when the material is heated during testing. Supposedly, the older the material is the brighter the light, as there has been time for more electrons to be trapped, and the dating method can be used for artifacts up to several hundred thousand years old. In practice, there are many uncontrollable variables that reduce the accuracy, and the older something is the less accurate the dating. The method is pretty good for artifacts dating from about 300-10,000 B.P. Charcoal from cooking fires and other or­ganic material can be dated using carbon 14, a radioactive isotope caused by ordinary carbon’s exposure to cosmic rays. Once the carbon is trapped by plants using atmospheric carbon dioxide for photosynthesis, the radiation begins to decrease as the carbon 14 decays back into ordinary carbon 12. Carbon 14 has a half life of 5,700 years, meaning that it is only half as radioactive after that time; so the older the material the less accurate the dating, with the maxi­mum being about 60,000 years. There are numerous other problems, including the possibility of contamination of samples, but carbon 14 dating, within the last few tens of thousands of years, is usually fairly accurate.

A number of years ago there were reports in the media of the discovery in the Amazon basin of the ruins of an­cient towns, roads, canals, and huge, earthen mounds. There were claims that some of the ruins might date back as far as 7,000 BP and that the Indians, presumably, had even dug canals connecting different rivers with one another. More recently, articles have been published with photographs and detailed information on this culture, but all refer­ences to canals actually connecting rivers have been dropped; and all accounts now claim that the culture dates back only to about 1,800 BP at the most and that it survived until about 700 BP Dozens of sites, ironically exposed by defo­restation, have been discovered. There are huge, geometric earthworks with canals (none of which, it is now claimed, connect rivers to one another), and mounds upon which towns were built. Other towns were surrounded by earthen walls and moats and housed up to 2,500-5,000 people each. The towns were built on high ground between rivers, usu­ally near springs, and the moats were up to 36 feet wide and three feet deep. The walls around the towns were low, about three feet, so their real function is a mystery; clearly they would not be effective for defense. The houses were presumably like those used by more recent Indians, constructed of wood and thatch (many of the contemporary ones are quite large, well engineered, and beautifully built). Of course, such structures would not survive long in the rain­forest. The Indians used fired ceramics, but, so far, there is no evidence of metals.

There is no evidence of domestic livestock, so presumably they hunted and fished for animal protein. Their agri­culture was quite advanced, and archaeologists are only beginning to understand it. One of their developments, if it can be fully understood, could have important benefits for modern inhabitants of the area. The soil in much of the Amazon is actually quite poor and is particularly deficient in many minerals, so when land is cleared for farming and ranching, often, after only a few growing seasons, it becomes infertile and a wasteland is created. But the ancient In­dians in these towns seem to have practiced a peculiar variant of slash and burn agriculture, somehow managing to control the burning so as to create large amounts of charcoal, which was then pulverized and worked into the soil. The tiny and highly absorptive charcoal grains hosted fungi and bacteria which seem to aid in capturing and retain­ing soil nutrients. The resulting black soil is now called “terra preta,” and if the technology can be relearned, the re­gion may become fertile farmland again.

Some archaeologists also suspect that the Indians modified the surrounding forests, planting more useful trees. Since this was not the kind of monoculture we practice today (with huge fields or orchards devoted to one crop), and since the trees were probably not planted in rows, we would not recognize such an area as being anything special. Note that North American Indians also modified the natural environment, sometimes burning wooded areas to create more grassland for deer and other game animals. This would be a kind of intermediate step between hunting and ani­mal husbandry, and the planting of useful trees would be intermediate between gathering and farming. A lot of our assumptions about early cultures are proving to be incorrect.

But what of early accounts of canals connecting rivers and of the culture dating back many thousands of years? Was this just a mistake, an exaggeration, or are archaeologists now covering something up or being overly conserva­tive? This has been known to happen. The massive Amazon system drains into the Atlantic Ocean, and the Orinoco system empties into the Caribbean. It is, to say the least, highly unusual for river systems going in different direc­tions to connect with one another naturally. For example, the Tigris and Euphrates, which flow almost parallel to one another through Iraq and whose deltas combine before reaching the Persian Gulf, are not connected at all in the mountains that are their source. A tributary of the Tigris will drain one way, and a tributary of the Euphrates, on the other side of a narrow ridge, will drain another way. But the Guarina River, a tributary of the Rio Negro, which flows into the Amazon, is connected by the 300 kilometer long Casiquiare River (if it is a river) to the upper Orinoco. This connection was, of course, always known to the local Indians, but the first Europeans to travel its entire length were the great German explorer and naturalist, Alexander von Humboldt and his French comrade, Aime Bonpland. Now it is (just barely) possible to imagine a way such a connection might be formed naturally. If the two drainages were once separated by high ground and then the river basins silted up until they were as high as the divide, and if there was a flood in one system but not the other, maybe, somehow, this could form without human intervention. But it looks like an incredibly long canal.

    There is There is no reason they could not have built canals. The Indians at Tenochtitlan spoke of an earlier great city in South America that they had anciently known and where they presumably to themselves received their advanced engineering of a similar scale & type urban infrastructure of most refined and sophisticated dimensions by contemporary standards. As well the natives in Massachusetts in earliest colonial times showed connected 3 river systems in the upper Charles River Basin that they said were used in an extensive trade network of highways paths and canals up the entire length of the Americas allowing trade between Central South and North American tribes. The curious element was the still intact empirical sovereign recognition of each local tribal chief along this route of obligation to keep the network repaired and open something that survived well into the European colonial era and that their titular designations were part of a recognized hierarchical order as in Europe with the degrees of nobility maintaining each regions infrastructure. The history written in colonial times has the Indians saying the canals connecting the rivers as well as still existing pre colonial dams and bridges of stone were the work of a very tall prince who joined the local tribe and that he possessed many skills and was long lived as well as being of high yellow coloring! I think its interesting that the great Chinese prince they unearthed at Teotihuacan within recent times received the briefest coverage before being whisked out of site with his burial treasures and the articles ordered removed from public record from some government source in Mexico. The Chinese Imperial records describe 5 sucessive emperors of Chinese origin of their New World or Mid American Empire before the coming of the Europeans. There were still Chinese empirical officials in the region when Columbus arrived as is mentioned in his work. The new world Imperium of China was considered an autonomous empire independant of China, gradually they were absorbed into native populations with the elite gradually withdrawing to the Orient,Africa and other regions where the Chinese trading Treaty Port culture existed.They attempted to bring Buddhism to the native Americans and it was limited in its success and influence. The only sucessful points were great cities of this anciently integrated Indo-Chinese Empire where intermarriage had created some generations of very advanced and evolved culture based on Hindu universalist science and Buddhist philosophy. Inevitably the distictions of genetic distinction probably involving elements of devolvement in the morphology of the governed masses led to the abandonment of the empire by these proto orientals in large part after their 5th and predicted last great Emperor died and was entombed shortly before the coming of the Europeans.

    I hope these few vignettes of real ancient colonial history help put together the greater complexity of our worlds forgotten history.

    So many modern discoveries are misinterpreted to fit our preconceived assumptions of our past history which so many times has been proved wrong. Makes you wonder why we keep doing that when so many times our past has been completely rewritten. Far too often mainstream archaeology has become nothing more than religion, you dont believe as they do then you are wrong.
