_Der Belus oder Sonnendienst auf den Anden oder Kelten in America_ by Frenzel, presents one field of theory which observations on the remains of the Incas’ walls suggest. The temptation to interpret by means of analogies to other remote civilizations is withstood with difficulty. From John Ranking and his _Historical Researches on the Conquest of Peru by the Mongols_, to Ignatius Donnelly and his evidence in favor of its conquest by the Egyptians via Atlantis, Peru has given an unlimited field for speculation. Lord Bacon believed, by the way, that Peru was a proud kingdom in the time of Atlantis. A striking example of immense erudition expended on a futile, though technically well-supported, fancy, is Rudolph Falb’s _Das Land der Inca_. Painstaking scholars are tracing out similarities between the Peruvian language and the Semitic and Phoenician tongues--“astounding affinities,” of which common stems are purest in Quichua, so that the human race seems to have emanated from the tops of the Andes; similarities, too, between Peruvians and the long-bearded Druids whose rites were chiefly sun-worship; they also kept memoranda with strings tied in different knots, like the _quipus_, and built vast structures of stone without tools. There are analogies between Peruvians and Hindus, who worshipped the Sun as Rama and called their first legislator Vaivasaonta, the Son of the Sun, and between Peru and Farther India. The Seccos have been called the Malays of Bolivia. There are analogies between Peruvians and Chinese, whose royal color was also yellow, whose peculiar god from earliest times was the Sun, who used _quipus_, who had terrace-cultivation and irrigation-systems like those of the Incas, who used foot-messengers for royal emissaries, and brought all the gold and silver of the realm for the beautifying of royal temples. “The buildings, religious institutions, division of time, and mystic notions,” which “seem in Asia to indicate the very dawn of civilization,” are found here upon the Andes. Whether there was intercommunication, or whether such facts merely suggest the instinctive discovery of all peoples, their origin is wrapped only in mystery--a veil whose lightest corner is only just lifting.
