The Peruvians, or Incas, were called the children of the sun. They had a sacred feeling for the heavenly bodies, and worshipped the sun as the creator and ruler of the universe. They had made some progress in astronomy, by a characterization of the sun and moon and chief planets, mostly for a religious purpose. However, they had used a calendar to represent the months, the year, and the changing seasons. Here, as elsewhere in primitive civilization, religion becomes an important factor in social control. The priest comes in as the interpreter and controller of mysteries, and hence an important member of the community. Religious sacrifices among the Peruvians were commonly of an immaculate nature, being mostly of fruits and flowers. This relieved them of the terrors of human sacrifices so prevalent in early beginnings of civilization where religion became the dominant factor of life. Hence their religious life was more moderate than that of many nations where religious control was more powerful. Yet in governmental affairs and in social life, here as in other places, religion was made the means of enslaving the masses of the people.

The government of the Incas was despotic. It was developed through the old family and tribal life to a status of hereditary aristocracy. Individuals of the oldest families became permanent in government, and these were aided and supported by the priestly order. Caste prevailed to a large extent, making a great difference between the situation of the nobility and the peasants and slaves. Individuals born into a certain group must live and die within that group. Hence the people were essentially peaceable, quiet, and not actively progressive. But we find that the social life, in spite of the prominence of the priest and the nobility, was not necessarily burdensome. Docile and passive in nature, they were ready to accept what appeared to them a well-ordered fate. If food, clothing, and shelter be furnished, and other desires remain undeveloped, and life made easy, what occasion was there for them to be moved by nobler aspirations? Without higher ideals, awakened ambition, and the multiplication of new desires, there was no hope of progress. The people seemed to possess considerable nobility of character, and were happy, peaceful, and well disposed toward one another, even though non-progressive conditions gave evidence that they had probably reached the terminal bud of progress of their branch of the human race.

As to what would have been the outcome of this civilization had not the ruthless hand of the Spaniard destroyed it, is a matter of conjecture. How interesting it would have been if these people could have remained unmolested for 400 years as an example of progress or retardation of a race. Students then could, through observation, have learned a great lesson concerning the development of the human race. Is it possible when a branch of the human race has only so much potential power based upon hereditary development, upon attitude toward life, and upon influence of environmental conditions, that after working out its normal existence it grows old and decays and dies, just as even the sturdy oak has its normal life and decay? At any rate, it seems that the history of the human race repeats itself over and over again with thousands of examples of this kind. When races become highly specialized along certain lines and are unadaptable along other lines, changes in climate, soil, food supply, or conflict with other races cause them to perish.

If we admit this to be the universal fate of tribes and races, there is one condition in which the normal life of the race can be prolonged, and that is by contact with other races which bring in new elements, and make new accommodations, not only through biological heredity, but through social heredity which causes a new lease of life to the tribe. Of course the deteriorating effects of a race of less culture would have a tendency to shorten the spiritual if not the physical life of the race. Whatever conjecture we may have as to the past and the probable future of such a race, it is evident that the Peruvians had made a strong and vigorous attempt at civilization. Their limited environment and simple life were not conducive to progressive ideas, and gave little inducement for inventive genius to lead the race forward. But even as we find them, the sum-total of their civilization compares very favorably with the sum-total of the civilization of the Spaniards, who engaged to complete their destruction. Different were these Spaniards in culture and learning, it is true, but their great difference is in the fact that the Spaniards had the tools and equipment for war and perhaps a higher state of military organization than the peace-loving Peruvians.

Aztec Civilization in Mexico.—When Cortez in 1525 began his conquest of Mexico, he found a strong political organization under the Emperor Montezuma, who had through conquest, diplomacy, and assumption of power united all of the tribes in and around Mexico City in a strong federation. These people were made up of many different tribes. At this period they did not show marked development in any particular line, except that of social organization. The people that occupied this great empire ruled by Montezuma, with the seat of power at Mexico City, were called Aztecs. The empire extended over all of lower Mexico and Yucatan. As rapidly as possible Montezuma brought adjacent tribes into subjection, and at the time of the Spanish conquest he exercised lordship over a wide country. So far as can be ascertained, arts and industries practised by most of these tribes were handed down from extinct races that had a greater inventive genius and a higher state of progress. The conquering tribes absorbed and used the arts of the conquered, as the Greeks did those of the conquered Aegeans.

The practice of agriculture, of the industrial arts, such as clothing, pottery, and implements of use and ornaments for adornment, showed advancement in industrial life. They built large temples and erected great buildings for the worship of their gods. There was something in their worship bordering on sun-worship, although not as distinctive as the sun-worship of the Peruvians. They were highly developed in the use of gold and copper, and produced a good quality of pottery. They had learned the art of decorating the pottery, and their temples also were done in colors and in bas-relief. They had developed a language of merit and had a hieroglyphic expression of the same. They had a distinct mythology, comprising myths of the sun and of the origin of various tribes, the origin of the earth and of man. They had developed the idea of charity, and had a system of caring for the poor, with hospitals for the sick. Notwithstanding this altruistic expression, they offered human sacrifices of maidens to their most terrible god.

As before stated, there were many tribes, consequently many languages, although some of them were near enough alike that members of different tribes could be readily understood. Also the characteristic traits varied in different tribes. It is not known whence they came, although their tradition points to the origin of the northwest. Undoubtedly, each tribe had a myth of its own origin, but, generally speaking, they all came from the northwest. Without doubt, at the time of the coming of the Spaniards, the tribes were non-progressive except in government. The coming of the Spaniards was a rude shock to their civilization, and with a disintegration of the empire, the spirit of thrift and endeavor was quenched. They became, as it were, slaves to a people with so-called higher civilization, who at least had the tools with which to conquer if they had not higher qualities of human character than those of the conquered.

The Earliest Centres of Civilization in Mexico.—Prior to the formation of the empire of the Aztecs, conquered by the Spaniards, there existed in Mexico centres of development of much greater antiquity. The more important among these were Yucatan and Mitla. A large number of the ruins of these ancient villages have been discovered and recorded. The groups of people who developed these contemporary civilizations were generally known as Toltecs. The Maya race, the important branch of the Toltecs, which had its highest development in Yucatan, was supposed to have come from a territory northeast of Mexico City, and traces of its migrations are discovered leading south and east into Yucatan. It is not known at what period these developments began, but probably their beginnings might have been traced back to 15,000 years, although the oldest known tablet found gives a record of 202 years B.C. Other information places their coming much later, at about 387 A.D.

All through Central America and southern Mexico ruins of these ancient villages have been discovered. While the civilizations of all were contemporaneous, different centres show different lines of development. There is nothing certain concerning the origin of the Toltecs, and they seemed to have practically disappeared so far as independent tribal life existed after their conquest by the Aztecs, although the products of their civilization were used by many other tribes that were living under the Aztec rule, and, indeed, traces of their civilization exist to-day in the living races of southern and central Mexico. Tradition states that the Toltecs reached their highest state of power between the seventh and the twelfth centuries, but progress in the interpretation of their hieroglyphics gives us but few permanent records. The development of their art was along the line of heavy buildings with bas-reliefs and walls covered with inscriptions recording history and religious symbols. One bas-relief represents the human head, with the facial angle shown at forty-five degrees. It was carved in stone of the hardest composition and was left unpainted.

Ethnologists have tried repeatedly and in vain to show there was a resemblance of this American life to the Egyptian civilization. In art, architecture, and industry, in worship and the elements of knowledge, there may be some resemblance to Egyptian models, but there is no direct evidence sufficient to connect these art products with those of Egypt or to assume that they must have come from the same centre. The construction of pyramids and terraces on a large scale does remind us of the tendency of the Oriental type of civilization. In all of their art, however, there was a symmetrical or conventional system which demonstrated that the indigenous development must have been from a common centre. Out of the fifty-two cities that have been explored which exhibit the habitations of the Toltec civilization, many exhibit ruins of art and architecture worthy of study.
