The point at which the legend preserved by Garcilasso is clearly at fault, is in its claim for the Incas as the first and only civilizers of Peru. We shall presently meet with other Peruvian myths of civilization which do not stand in the least connection with Manco Capac and the Incas. The kingdom of Quito, which the Inca Huayna Capac had recently conquered when the Spaniards arrived, though not on the same level as Peru proper, was far removed from the savage state, while as yet a stranger to the influence of the Incas. The country of the Muyscas, the present New Granada or land of Bogota, though standing in no connection with Peru, was the theatre of another sacerdotal and solar religion _sui generis_, which, though very little known, is highly interesting. The valley of the Rimac, or Lima, and the coast lands in general, were likewise centres of a pre-Inca civilization. The Chimus especially, themselves dwellers on the coast, were possessed of an original civilization differing from that of the Incas. They were the last to be conquered. To sum up, everything leads us to suppose that various centres of social development had long existed, up and down the whole region, but that, under the presiding genius of the priesthood of Manco Capac, the civilization of Cuzco had gradually acquired the preponderance, till it consecutively eclipsed and absorbed all the others.

Garcilasso labours hard to impress us with the belief that the sovereigns of his family maintained an unbroken age of gold, by dint of their wisdom and virtues. But we know, both from himself and from other sources, that as a matter of fact the Incas' sky was not always cloudless. They had numbered both bad and incapable rulers in their line. More than once they had had to suppress terrible insurrections, and their palaces had witnessed more than one tragedy."[64] But after making all allowances, we must admit that they succeeded in governing well, and more especially in maintaining intact their own religious and political prestige.

Now this very cleverness, this conscious and often extremely deliberate and astutely calculated policy, compels us to ask how far the Incas themselves were sincere in their pretension to be descended from the Sun, and their faith in the very special favour in which the great luminary held them. There is so much rationalism in their habitual tactics, that one cannot help suspecting a touch of it in their beliefs. And the truth is that their descendant, Garcilasso, has recorded certain traditions to that effect, which he has perhaps dressed up a little too much in European style, with a view to convincing us that his ancestors were monotheistic philosophers, but which nevertheless bear the marks of a certain authenticity. For the reasoning which Garcilasso puts into the mouth of the Incas closely resembles what would naturally commend itself to the mind of a pagan who should once ask himself whether the visible phenomenon, the Sun, which he adored, was really as living, as conscious, as personal, as they said. Thus the Inca Tupac Yupanqui (fifteenth century) is said to have reasoned thus:[65]
