Presently I'm reading the book: Ancient Titicaca, The Evolution Of Complex Society In Southern Peru And Northern Bolivia by Charles Stanish, 1956.
On page 206, here is what is written: Most of what we know about the great pre-Inca Aymara senorios of the Titicaca Basin comes from the information recorded by Cieza, Cobo and other early historians. In one of the most important quotes about the pre-Inca peoples, Cieza relates:
"Before the Inca reigned, according to many Indians from Collao, there was in their province two great lords (senores), one named Zapana and the other Cari, and these senores conquered many pucaras that are their fortifications, and that one of them entered Lake Titicaca, and found on the major island (Isla del Sol) bearded white people with whom they fought and put all of them to death. And more people say, that after (these events), there were great battles with the Canas and Canchis. (Cieza 1553: chapter 100).
More reports of white people in the Andes. Chachapoyas?
I'd like to get to the bottom of this mystery one day.
