is with races of men as with individuals, the progressive growth of youth soon reaches its limit and maturity of power. While it brings greater strength, it has not the buoyancy of early years, so the manner of life becomes fixed, and onward progress stops. They can then only hope to hold on the even tenor of their way, happy if increasing years do not bring again their childhood state. The Neolithic people entered Europe early in the youth of the race which spread their civilization over the globe, but the race to which they belonged appear to have reached their zenith of development long ages ago, since which time, whatever higher culture they have reached has been a gift to them by other people. Their energies became exhausted, and for a long series of years Europe was filled by the camps, lake villages and fortified places of Neolithic times.
As to the absolute length of time during which they inhabited Europe, we have no data to determine. Relatively, their sojourn, however long, was but a short time compared to the duration of the old Stone Age. It presents no such evidence of lapse of ages as can be observed in the older deposits, yet we may be sure that it was for no inconsiderable period.
The Paleolithic Age was apparently terminated in Europe by the cold of the last glacial epoch. No such natural course put an end to the Neolithic Age, but as the strong have an advantage over the weak, the young over the old, so does a race young, undeveloped, or in the early maturity of its powers, have an advantage over the older and more fixed civilization with which it comes in contact. To understand the causes which introduced into Europe the Bronze Age, we must refer to the Aryan race and to Asia.
We have in the preceding chapter briefly mentioned the Aryan race. They have so much to do with the higher culture of the Metallic Ages, that it seems not out of place to refer once more to their origin. The evidence goes to show that the ancient Aryans inhabited some portion of South-western Asia. As a race or family, they appear to have been one of the latest developed. Yet a record of their progress is a record of civilization.
Unless we reflect, we are liable to be misled by the expression, recent development. The Hindoos, one of the latest members of this family, were in India several thousand years before Christ.2 But however far back we trace them, we find them in possession of metals. Aside from this, we know that before the different Aryan tribes had commenced their migration (with the exception, however, of the Celts), while they formed but one mass of people, they worked some of the metals.3 They could have acquired this knowledge only after the passage of many years, when they were ignorant of it. This bespeaks a profound antiquity for the Aryan family.
As we have seen, Europe, while yet inhabited by Neolithic people, was invaded by a branch of the Aryans. We do not know the date of this invasion, yet it must have been an early date, since the Celts separated from the Aryans before the use of metals. The Aryans have ever been noted as an aggressive people, and under different names have, in modern times, carried victorious arms in all quarters of the globe. This is equally characteristic of the primitive Aryans. Though it is not apparent that they possessed any higher culture than the people who already inhabited Europe, yet they everywhere triumphed over them and possessed themselves of the fairest portion of the Neolithic domain, driving the primitive inhabitants to those mountainous regions where their descendants are found to-day.
It is not probable that the Aryan invaders waged exterminating war against the Neolithic tribes. The evidence shows that there was considerable mingling of the two races. It has been suggested, however, that the Neolithic people who were not driven away were reduced to slavery.4 However that may be, the remains of the two people are found side by side in chambered tombs and sepulchral caverns, showing that they dwelt together in the same area. As before remarked, the Aryan invaders are identified as the Celts. That it was relatively late in the Neolithic Age when they made their appearance, is shown by the fact that they had only reached the English Channel when a knowledge of bronze caught up with them.
We must now endeavor to learn the origin of bronze. The impulsive energies of this newer race found vent not only in conquest over the neighboring tribes, but it is extremely probable that they are the ones who first compelled nature to yield up her metallic stores to be of service to man. If the knowledge of fire was the starting point of human advancement, surely the knowledge of metals, their useful properties, and how to extract them from their ores, may lay claim to being the starting point of our present enlightenment. We have but to glance around us to see how many of our daily comforts are dependent on the use of metals. Should we, by any mischance, become deprived of the use of iron, or of the useful alloys, bronze and brass, our civilization would be in great danger of reverting to Savagism. Man, destitute of metals, can do but little to improve his surroundings; but grant him these, and victory over his environment is secured.
We can not retrace the exact steps of this beautiful discovery; we are not sure to what family it is to be ascribed. Perhaps not to any one alone. Nature may have taken her children by the hand, and kindly guided their feeble steps in the line of experiments leading up to this knowledge, and, finally, one family, more fortunate than the others, succeeded in the attempt. All great discoveries have been approached in different directions, by different people. No sooner is it made than this fact appears, and people widely separated by time and place are found to be on the verge of the same great truth. It was probably so at the discovery of metallurgy.
