Taking all this into consideration, the archæologist cannot remain satisfied with the brief remark of certain historians that "in this tradition we trace only another version of the story of the civilization common to all primitive nations, and that imposture of a celestial relationship whereby designing rulers and cunning priests have sought to secure their ascendency among men." No more is it an explanation to say that "Manco Capac is the almost exact counterpart of the Chinese Fohi, the Hindu Buddha, the terrestrial Osiris of Egypt, the Quetzalcoatl of Mexico, and Votan of Central America"; for all this is but too evident. What we want to learn is how came these nations, so antipodal to each other as India, Egypt, and America, to offer such extraordinary points of resemblance, not only in their general religious, political, and social views, but sometimes in the minutest details. The much-needed task is to find out which one of them preceded the other; to explain how these people came to plant at the four corners of the earth nearly identical architecture and arts, unless there was a time when, as assured by Plato and believed in by more than one modern archæologist, no ships were needed for such a transit, as the two worlds formed but one continent.
