But this tradition is only one of several current among the Peruvian Indians, and probably not the one most generally received. Another legend speaks of certain white and bearded men, who, advancing from the shores of Lake Titicaca, established an ascendancy over the natives, and imparted to them the blessings of civilization. It may remind us of the tradition existing among the Aztecs in respect to Quetzalcoatl, the good deity, who with a similar garb and aspect came up the great plateau from the east on a like benevolent mission to the natives. The analogy is the more remarkable, as there is no trace of any communication with, or even knowledge of, each other to be found in the two nations.11 The date usually assigned for these extraordinary events was about four hundred years before the coming of the Spaniards, or early in the twelfth century.12 But, however pleasing to the imagination, and however popular, the legend of Manco Capac, it requires but little reflection to show its improbability, even when divested of supernatural accompaniments. On the shores of Lake Titicaca extensive ruins exist at the present day, which the Peruvians themselves acknowledge to be of older date than the pretended advent of the Incas, and to have furnished them with the models of their architecture.13 The date of their appearance, indeed, is manifestly irreconcilable with their subsequent history. No account assigns to the Inca dynasty more than thirteen princes before the Conquest. But this number is altogether too small to have spread over four hundred years, and would not carry back the foundations of the monarchy, on any probable computation, beyond two centuries and a half,-an antiquity not incredible in itself, and which, it may be remarked, does not precede by more than half a century the alleged foundation of the capital of Mexico. The fiction of Manco Capac and his sister-wife was devised, no doubt, at a later period, to gratify the vanity of the Peruvian monarchs, and to give additional sanction to their authority by deriving it from a celestial origin. We may reasonably conclude that there existed in the country a race advanced in civilization before the time of the Incas; and, in conformity with nearly every tradition, we may derive this race from the neighborhood of Lake Titicaca; 14 a conclusion strongly confirmed by the imposing architectural remains which still endure, after the lapse of so many years, on its borders. Who this race were, and whence they came, may afford a tempting theme for inquiry to the speculative antiquarian. But it is a land of darkness that lies far beyond the domain of history.15
