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.
