El Cascabel
The most important feature of El Fuerte seems to be El Cascabel. El Cascabel can be translated as 'The Rattle'. Two parallel lines point to certain points in the eastern sky at a position of azimuth 71° and an altitude of about 6.75° . One could have looked along the parallel lines, standing on the place of observation in front of the Inca-wall at the foot of El Fuerte and watched the parallel rising of two planets at sunrise on August 20, 1066 above both lines against the background of constellation Leo: Venus and Jupiter. Some archaeologists contend that unusual carvings on the rocks may be from a pre-Inca civilization on this Amazonian slope who were commemorating the flyover of Halley's Comet in March 1066.
More recently, it has been pronounced to be an ancient flying object launching and landing site by the pseudoarcheologist Erich Von Daniken, well-known author of Chariots of the Gods?.
