The social life of these people centred about the households of their leading men. The hall of the chief where they settled for a time was often a very capacious timber building. There were no doubt huts for herds and outlying farm buildings; but with most of the Aryan peoples this hall was the general centre, everyone went there to feast and hear the bards and take part in games and discussions. Cowsheds and stabling surrounded it. The chief and his wife and so forth would sleep on a dais or in an upper gallery; the commoner sort slept about anywhere, as people still do in Indian households. Except for weapons, ornaments, tools and suchlike personal possessions there was a sort of patriarchal communism in the tribe. The chief owned the cattle and grazing lands in the common interest; forest and rivers were the wild. This was the fashion of the people who were increasing and multiplying over the great spaces of central Europe and west central Asia during the growth of the great civilization of Mesopotamia and the Nile, and whom we find pressing upon the heliolithic peoples everywhere in the second millennium before Christ. They were coming into France and Britain and into Spain. They pushed westward in two waves. The first of these people who reached Britain and Ireland were armed with bronze weapons. They exterminated or subjugated the people who had made the great stone monuments of Carnac in Brittany and Stonehenge and Avebury in England. They reached Ireland. They are called the Goidelic Celts. The second wave of a closely kindred people, perhaps intermixed with other racial elements, brought iron with it into Great Britain, and is known as the wave of Brythonic Celts. From them the Welsh derive their language.

A closely allied series of tribes, the Italians, were making their way down the still wild and wooded Italian peninsula. They did not always conquer. In the eighth century B.C. Rome appears in history, a trading town on the Tiber, inhabited by Aryan Latins but under the rule of Etruscan nobles and kings.
