Note. I have not thought it necessary to swell this Introduction by an inquiry into the origin of the Peruvian civilization, like that appended to the history of the Mexican. The Peruvian history doubtless suggests analogies with more than one nation in the East, some of which have been briefly adverted to in the preceding pages; although these analogies are adduced there not as evidence of a common origin, but as showing the coincidences which might naturally spring up among different nations under the same phase of civilization. Such coincidences are neither so numerous nor so striking as those afforded by the Aztec history. The correspondence presented by the astronomical science of the Mexicans is alone of more importance than all the rest, Yet the light of analogy, afforded by the institutions of the Incas, seems to point, as far as it goes, towards the same direction; and as the investigation could present but little substantially to confirm, and still less to confute, the views taken in the former disquisition, I have not thought it best to fatigue the reader with it.
Two of the prominent authorities on whom I have relied in this Introductory portion of the work, are Juan de Sarmiento and the Licentiate Ondegardo. Of the former I have been able to collect no information beyond what is afforded by his own writings. In the title prefixed to his manuscript, he is styled President of the Council of the Indies, a post of high authority, which infers a weight of character in the party, and means of information, that entitle his opinions on colonial topics to great deference.
These means of information were much enlarged by Sarmiento's visit to the colonies, during the administration of Gasca. Having conceived the design of compiling a history of the ancient Peruvian institutions, he visited Cuzco, as he tells us, in 1550, and there drew from the natives themselves the materials for his narrative. His position gave him access to the most authentic sources of knowledge, and from the lips of the Inca nobles, the best instructed of the conquered race, he gathered the traditions of their national history and institutions. The quipus formed, as we have seen, an imperfect system of mnemonics, requiring constant attention, and much inferior to the Mexican hieroglyphics. It was only by diligent instruction that they were made available to historical purposes; and this instruction was so far neglected after the Conquest, that the ancient annals of the country would have perished with the generation which was the sole depositary of them, had it not been for the efforts of a few intelligent scholars, like Sarmiento, who saw the importance, at this critical period, of cultivating an intercourse with the natives, and drawing from them their hidden stores of information.
