From Mysteries of Ancient South America, Page 48, by Harold T. Wilkins:
"Another of these old Atlantean cities was visited by Fray Pedro Ciezade Leon, a Spanish soldier-monk, who died in A.D. 1560. It was called Guamanaga, and is and was located on the great cordillera in latitide 12* 59' S, longitude 73* 59' W. Ciez was tremendously impressed by the great edifices he saw there, all in ruins.
"Who built them?" he asked the natives.
A bearded White people, like you Spaniards," said a cacique.
"They came to these parts many ages before the Incas began to reign and formed a settlement here ... They do not seem to me to be Inca buildings; for they are square, not long and narrow. It is also reported that certain letters were found on a tile in these buildings ... the indians also speak of bearded white men in the island. of Titicaca."(Cieza de Leon)
