Thus in Italy, the development from the tribal to the national state was internal. No precocious maritime race awoke in many different centres the seeds of nationality; rather this nationality was a gradual growth from one root, the slow response to a central attractive force. The energy of Rome did not go out in sea adventure, or in the colonization of distant lands; but it was firmly bent to absorb the different people of her own peninsula, people of like blood with herself, but in every early stage of culture from an almost nomadic condition to one of considerable advancement in the arts of peace.
When from the Greeks and Romans we turn to the Celts and Teutons, we must descend much lower in the records of history before we can get any clear glimpse at these. The Celts, who were probably the first Aryans in Europe, seem gradually to have been forced farther and farther west by the incursions of other peoples. At one time, however, we have evidence that they extended eastward, at least as far as the Rhine, and over all that northern portion of Italy--now Lombardy and part of Sardinia--which to the Romans went by the name of Cisalpine Gaul. The long period of subjection to the Roman rule which Gaul experienced, obliterated in that country all traces of its early Celtic manners, and we are reduced for our information concerning these to the pages of Roman historians, or to the remains of Celtic laws and customs preserved in the western homes of the race. The last have only lately received a proper attention. The most primitive Irish code--the Brehon laws--has been searched for traces of the primitive Celtic life. From both our sources we gather that the Celts were divided into tribes regarded as members of one family. These clans were ruled over by chiefs, whose offices were hereditary, or very early became so. They were thus but slightly advanced out of the most primitive conditions,--they cannot be described as a nation. Had they been so, extensive and warlike as they were, they would have been capable of subduing all the other infant nationalities of Aryan folk. As it was, as mere combinations of tribes under some powerful chieftain (Cæsar describes just such), they gave trouble to the Roman armies even under a Cæsar, and were in early days the most dreadful enemies of the Republic. Under Brennus, they besieged and took Rome, sacked the city, and were only induced to retire on the payment of a heavy ransom. A hundred years later, under another Brennus, they made their way into Thrace, ravaged the whole country, and from Nicomedes, King of Bithynia, obtained a settlement in Asia Minor in the district which from them received the name of Galatia. The occurrence of those two chiefs named Brennus shows us that this could hardly have been a mere personal name. It is undoubtedly the Celtic Brain, a king or chieftain, the same from which we get the mythic Bran,[142] and in all probability the Irish O’Brien. The recognition of the Celtic fighting capacity in the ancient world is illustrated by another circumstance, and this is more especially interesting to us of the modern world, whose army is so largely made up of Celts from Ireland and Scotland (Highlanders). Hierôn I., the powerful tyrant of Syracuse, founded his despotism, as he afterwards confessed, chiefly upon his standing army of thirty thousand Gaulish mercenaries whom he kept always in his pay.
