"The question is easier asked than answered. Unfortunately for us, the Peruvians had no system of writing, like the ancient Egyptians, and therefore there are no records by which we can learn their history. To get at the antiquity of the people we must judge by the traditions that have come down to us and by the effect of time upon the monuments they have left. This enables us to guess at the date of the construction of their temples, and it is proper to remark that the guesses of archæologists who have studied the subject have been very far apart.
PERUVIAN IDOL.
"The government of the Incas, which the Spaniards found and destroyed, is supposed to have existed not less than five hundred years, though some writers give it twice or three times that duration. When the Spaniards came here they found nearly all of what is now Peru, Ecuador, Bolivia, and a part of Chili united under one form of government, under three great tribes or families: the Aymaraes, the Chinchas, and the Huancas. The first of these, the Aymaraes, was the ruling race, and from it came the Incas or emperors. They occupied the high lands of Peru and Bolivia, and were said to have been more advanced in civilization than either of the others; the Chinchas dwelt mostly along the coast, while the Huancas were scattered through the mountain region between the Aymaraes and the Chinchas.

"Gradually the Aymaraes conquered the other great tribes, and their system of conquest and colonization is an interesting study.
"The tradition is that the tutelary divinity, the sun, sent his own children to instruct and govern the people, who were at war with each other, and had sunk into a condition of barbarism. These children of the sun were Manco Capac and his sister and wife, Mama Oello; they appeared first on an island in Lake Titicaca, and the island was ever afterwards regarded as holy. There are many temples around the lake and on the island to which they descended from heaven; we shall have more to say about these temples at another time.
