Documentary evidence certainly justifies the inference that the civilization of Peru itself was due to just such a deliberately executed plan of colonization, which gradually extended southwards and ultimately took root and flourished in the most favorably situated locality. Leonce Angrand, who cites Acosta, Montesinos, Garcia, Boturini, Valera, Garcilaso de la Vega, Gomara, Balboa, Paz Soldan, d’Orbigny, Zarate, Cieza de Leon, Torquemada, Herrera, Velasco, Rivero and Tschudi, Gibbon, Stevenson, Castelnau, Desjardins, Villavicencio, Roman and others, unites their testimony in the following sentence: “It is therefore solely towards the North, in the elevated mountainous region, that researches should be directed [in order to ascertain the origin of the Peruvian civilization]. As soon as this is done innumerable proofs appear of the residence, in extremely ancient times, of people who can scarcely belong to other races than those who founded Cuzco and Tiahuanaco. It is therefore, from the North that these hardy pioneers of humanity came, from distant civilizations, and it is certainly by going northwards that one must look for traces of one or the other current of civilization. The inexhaustible force of expansion of the Inca Empire extended to the North as well as in other directions.” Angrand also mentions a line “of prehistoric ruins which extend northwards from Peru and display the essentially characteristic outlines of the Mexican Teocallis or temples.”(24) Garcilaso de la Vega, citing Padre Blas Valera, goes so far as to state that the race, which introduced human sacrifices and ritualistic cannibalism into Peru, “had come from the region of Mexico, peopled the regions of Panama and the Isthmus of Darien and all those great mountains which extend between Peru and the new kingdom of Granada” (the present Nicaragua).(25) According to Padre Anello Oliva, whose manuscript notes on Peru are preserved in the British Museum Library, the immediate ancestors of the Incas were colonists who came from unknown parts either by land or by sea, and settled at Caracas (Atlantic coast), whence they gradually spread southwards. As his authority for this statement, he cites original manuscripts which had been placed in his hands by a Spanish missionary of high standing. Among these was a relation by a Quipucamayoc or “accountant by means of quippus,” named Catari, who had been a chronicler of the Incas. His forefathers had occupied the same post and had handed down the above record as having been related to them by their predecessors. This account does not disagree with that of Salcamayhua who states that “all the nations of the empire had come from beyond Potosi, in four or five armies, arrayed for war and settled in the districts as they advanced.”
