Great ancient civilizations in amazonia? ridiculous!

Even though the first Europeans who sailed up the Amazon circa 1540 reported large, well-populated cities on the Amazon flood plains, modern archeologists have generally traveled to the high Andes for "high" ancient civilizations in South America. In retrospect, this is not surprising. By 1700, the cities of the 1540s had been swallowed up by the jungle. Besides, most thought, the conditions in the lowland tropics are too harsh to nourish advanced societies. Fortunately, a few archeologists have recently invaded Amazonia with aerial sensors, magnetometers, and the oldfashioned shovel. And indeed there once was a high civilization along the great river; and, some say, it may have spread from the lowlands to the Andes far to the west. What a turnabout in archeological outlook -- if sustainable by facts.

One intriguing site in Amazonia is the island of Marajo, 15,000 square miles in area, located at the mouth of the Amazon. Here are found some 400 huge dirt mounds, including one with a surface area of 50 acres and a volume of a million cubic yards. Radiocarbon dates suggest that Marajo had been occupied for over a thousand years.

Nearby, on the Tapajos River in Brazil, A. Roosevelt found elaborate pottery, finely carved jade, and a culture going back perhaps 7,000 years.

In other parts of Amazonia, surveys uncovered tens of thousands of acres of raised fields connected by causeways. There remains little doubt that an advanced, complex civilization dwelt in Amazonia for millennia. Archeologists are now asking where these people came from and how they were related to the Incas to the west and civilizations to the north in Central America.

Quotes

  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
