Investigations of recent scholars show that the bronze of the early Bronze Age came from Asia Minor. Subsequently there were three great centers of bronze production, each having certain styles. These were the Russian on the east, the Scandinavian on the north, and the Mediterranean on the south. If this view be correct, bronze must have been in use in the South of Europe long before it was in the North. This view of the introduction of bronze is, we think, that of the best scholars in Europe. Others, however, think bronze was brought in by the invasion of the Aryan tribes. Mr. Keary says: “The men of the Bronze Age were a new race, sallying out of the east to dispossess the older inhabitants, and if, in some places, the Bronze men and the Stone men seem to have gone on for a time side by side, the general characteristic of the change is that of a sudden break.”9 We have shown that it was carried to England by an invasion, and it was, perhaps, so introduced into Denmark, but in other countries of Europe by trade.10
Let us now see what change in the home life, in the culture of the people, would be brought about by the use of bronze. We must reflect that we are not to deal with some new race, but with the same race that inhabited Europe at the close of Neolithic times. The people who had triumphed over nature with their implements of stone were now put in possession of weapons and implements of greatly increased efficiency. The results could not fail to advance their culture. We would not expect any great change in the houses. They would, however, be much better built. The metallic tools were certainly a long ways ahead of the best stone implements. With the aid of metallic axes, knives, saws, gouges, and chisels, their cabins could be increased in size and appearance. They still built settlements over the lakes, but the Bronze Age settlements were more substantially built, and placed farther out from shore. Fortified places were still numerous; the remains of thousands of them of this age have been found in Ireland. But the forests were cleared, wild animals disappeared, society became more settled, and we may be sure that an increasing number of little hamlets were scattered over the country.
