From this description it is “clear that but a small portion of the country was inhabitable, or capable of supporting a considerable number of people. The rich and productive valleys and bolsons are hardly move than specks on the map.”5 It is necessary that we bear this description of the country in mind. It will help us to understand as nothing else will how the tribes located in one rich and productive bolson could, by successive forays, reduce to a condition of tribute tribes living in other detached valleys and bolsons. It will also enable us to put a correct estimate on the extravagant accounts that have reached us of the population of this country under the rule of its ancient inhabitants. We can also readily see why the tribes living in the hot and fertile valleys along the coast, which were called Yuncas by the Peruvians, should differ in religion and mental and moral characteristics from the tribes living in the bolsons of the interior, where the snow-clad peaks were nearly always in sight, and where the sun, shedding his warm and vivifying beams, would appear to the shivering natives as the beneficent deity from whence comes all good.

We must now turn our attention to the tribes inhabiting the section of country just described. We have seen that the Mayas, of Central America, the Nahuas, of Mexico, and the sedentary tribes, of the United States, were considerably in advance of the great body of the Indian tribes of North America. We find the same fact true of the natives of South America. Those tribes inhabiting the territory of ancient Peru, and those of the territory now known as the United States of Columbia, were considerably further advanced than the wild tribes living in the remaining portions of South America. Quite a number of our scholars have grouped in one class these partially civilized tribes of both North and South America, and called them the Toltecan Family.6 But others do not think that there are sufficient grounds for such a class division. They can not detect any radical changes in the domestic institutions of the various tribes.7 On this point we must wait until our authorities are agreed among themselves.

Attempts have been made to classify the various partially civilized tribes of Peru. There are several difficulties in the way. It was, for instance, the custom of the Incas, whenever they had reduced a tribe to tribute, to force them to learn their language, which was the Quichua, and is what the early Spanish writers call the general language of Peru.8 How far this language was forced on the tribes, and how far it was their own idiom, we can not tell. Mr. Markham, who has made a very careful study of all the authorities bearing on Peru, divides the territory of ancient Peru into five divisions, and in each locates a number of tribes, which he thinks forms a family.

The first, and most northern one, extends north from near Tumbez, in the present State of Ecuador. The second extends from Loja, on the north, to Cerro De Pasco, in about eleven degrees south latitude. The third, and most important, extends from this last named place to the pass of La Raya, fifteen degrees south latitude. This was the home of the Incas and five other closely related tribes. To the south of La Raya is the basin of Lake Titicaca, the home of a family of Indians generally known as the Aymara Indians. This name is, however, wrong; these tribes should be called the Collao Indians. These four divisions do not include any territory west of the Cordillera range, except one part of the third division. These four families are all closely related. Mr. Markham thinks they all had a common origin. Mr. Squier thinks the Collao, or, as they are generally called, the Aymara Indians, are distinct from the others. “They differ from each other as widely as the German’s differ from the French,” is his own conclusion. The entire coast district of Peru was the home of many tribes of Indians, about which we as yet know but little. The name by which they are known is Yuncas.9

We are now ready to proceed to a consideration of the culture of ancient Peru, and a description of the monuments. But before doing so we must have a word to say as to the authorities. At the time of the Spanish conquest of Peru, the Empire of the Incas was supposed to have been in existence about four hundred years. But the Incas had no hieroglyphic or pictorial system of recording events. The most they had was a system of knot records or quippos, which will be explained in due time. These records were simply aids to the memory. Mr. Squier places them “about on a par with Robinson Crusoe’s Notched Calendar, or the chalked tally of an illiterate tapster.”10 They are manifestly of no value as historical records.

It must be evident, then, that all our knowledge of Peru, previous to the arrival of the Spaniards, rests solely upon traditions. We have no reason to suppose that these traditions are of more value in their case than in the case of other rude and illiterate people. The memory of such people is very short lived. The tribes in the southern part of the United States must have been greatly impressed with Do Soto’s expedition. They heard fire-arms for the first time, and for the first time saw horses ridden by men. Yet in the course of a few generations they had completely forgotten all this.11

One very eminent authority is Garcillasso De La Vega.12 Let us examine his writings a minute. He was born in Cuzco about 1540, but a few years after the conquest. His mother claimed descent from the royal family. He left Peru in 1560, when he was just twenty years old, and went to Spain. He first sought advancement in the army. Despairing of success in that line, he turned his attention to literature. One of his first works was an account of De Soto’s expedition to Florida. The historian Bancroft thus characterizes this work: “An extravagant romance, yet founded upon facts—a history not without its value, but which must be consulted with extreme caution.” Yet in this work there were no subtile ties of blood, no natural bias as there would be in favor of the land of his birth.

About 1600 he commenced his “Royal Commentaries of Peru.” This is the main source of information as to ancient Peru. We must reflect that he had been away from his native land forty years when he commenced the work. His sources of information were the stories told him in his boyhood days, the writings of the Spanish travelers, monks, and conquerors, and what he learned by corresponding with his old friends in Peru, which he did when he formed the design of writing his history. In other words, his history rests on the traditions extant at the time of the conquest, viewed, however, from a distance of sixty years. Who can doubt but what the old man, writing his accounts of this mother’s race, that race that had been so deeply wronged, wrote it under the influence of that potent spell, which the memory of old age throws around childhood’s days?

It is evident we have in these accounts but little deserving the name of history. When he undertakes to tell us of the doings of the Incas, who are supposed to have reigned three or four hundred years before the Spanish conquest, descending to such details as what nations they subdued, the size of their armies, their speeches to their soldiers, the words of counsel they addressed to their heirs, their wise laws and maxims—and we know that this account rests on traditions—he who believes that they are of historical value, is surely possessed of a good store of credulity. We do not mean to say that his writings are of no account. On the other hand, they are of value. The historical part we are to consider simply as traditions, and we are to weigh them just as we would any other collection of traditions and compare them with monuments still extant. He is good authority on the customs and manners of the Peruvians just previous to the arrival of the Europeans.
