The first Nordics to appear in European history are tribes speaking Aryan tongues in the form of the various Celtic and related dialects in the West, of Umbrian in Italy and of Thracian in the Balkans. These barbarians, pouring down from the North, swept with them large numbers of Alpines whom they had already thoroughly Nordicized. The process of conquering and assimilating the Alpines must have gone on for long centuries before our first historic records and the work was so thoroughly done that the very existence of this Alpine race as a separate subspecies of man was actually forgotten for many centuries by themselves and by the world at large until it was revealed in our own day by the science of skull measurements. The Hallstatt iron culture did not extend into western Europe and the smelting and extensive use of this metal in southern Britain and northwestern Europe are of much later date and occur in what is called the La Tène Period, usually assigned to the fifth and fourth century B. C. Iron weapons were, however, known sporadically in England much earlier, perhaps as far back as 800 B. C., but were very rare and were probably importations from the Continent. “Hallstatt relics have only been found in the northeast or centre of France and it appears that the Bronze Age continued in the remainder of that country until about 700 B. C.” The spread of this La Tène culture is associated with the Nordic Cymry, who constituted the last wave of Celtic-speaking invaders into western Europe, while the earlier Nordic Gauls and Goidels had arrived in Gaul and Britain equipped with bronze only. In Roman times, following the La Tène Period, the main races of Europe occupied the relative positions which they had held during the whole Neolithic Period and which they hold to-day, with the exception that the Nordic subspecies was less extensively represented in western Europe than when, a few hundred years later, the so-called Teutonic tribes overran these countries; but on the other hand, the Nordics occupied large areas in eastern Germany, Hungary, Poland and Russia now mainly occupied by the Slavs of Alpine race. Many countries in central Europe were in Roman times inhabited by fair-haired, blue eyed barbarians, where now the population is preponderantly brunet and becoming yearly more so.
