“Our friend, the Peruvian explorer and philosopher Daniel Ruzo, went off in 1952 to investigate the desert plateau of Marchusai situated at a height of 3,800 metres to the west of the Cordillera of the Andes. […] Ruzo found there animal and human faces carved in the rock and visible only at the summer equinox, thanks to a particular combination of light and shade. He found there statues of animals belonging to the secondary era such as the stegosaur […] The geological indications go back to the remotest antiquity. Ruzo thinks that this plateau may have been the cradle of the Masma civilization, the oldest in the world.” (p. 114)
Of particular interest is that Pauwels and Bergier report Ruzo’s “discovery” a full 14 years before Ruzo turned it into his own book, Marcahuasi: The Story of a Fantastic Discovery (1974).
A few pictures of the Marcahuasi (Markawasi) “statues” make obvious that this is little more than wishful thinking applied to natural geologic formations; this of course did not stop Ancient Aliens from repeating Ruzo’s theory that these rocks were eroded remnants of a prehistoric sculpture garden. The fact that the “faces” were visible only once a year under special lighting conditions ought to have indicated that this was just another example of “Jesus in the tortilla”--pareidolia—seeing faces in random patters.
