Strange Megalithic Monuments In The Central Sahara

Archeologists have recently made some spectacular discoveries of megalithic structures in the central Sahara. This region boasts many V-shaped prehistoric monuments as well as spiral and meandertype carvings. There are even a few cup-and-ring markings, like those so prevalent in northern Europe. Most curious are the so-called "axle-type" monuments, which consist of a central hub with two straight projecting arms.

Early in 1981, the monument shown in the sketch was found in the Immidir district. It is basically V-shaped, with two sets of "auxiliary" arms, one V-type and one axle-type, both of which are detached from the hub like "spare parts." The tips of the north-south arms in the sketch are about 75 meters apart. Clearly, orientation was important to the builders of the monuments, but the asymmetry and auxiliary arms are puzzling. The stonework in these central Saharan monuments is good. Dates are elusive, but all indications are that the sites are ancient.

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
