In each of those great primitive stocks, an all-wise Providence introduced a large number of sub-races, if we may be allowed to call them so, out of which are sprung the various nations whose intermingling forms the web of human history. Our object is to consider only the Celtic branch. For, whatever may be the various theories propounded on the subject of the colonization of Ireland, from whatever part of the globe the primitive inhabitants may be supposed to have come, one thing is certain, to-day the race is yet one, in spite of the foreign blood infused into it by so many men of other stocks. Although the race was at one time on the verge of extinction by Cromwell, it has finally absorbed all the others; it has conquered; and, whoever has to deal with true Irishmen, feels at once that he deals with a primitive people, whose ancestors dwelt on the island thousands of years ago. Some slight differences may be observed in the people of the various provinces of the island; there maybe various dialects in their language, different appearance in their looks, some slight divergence in their disposition or manners; it cannot be other wise, since, as we have seen, no two individuals of the human family can be found perfectly alike. But, in spite of all this, they remain Celts to this day; they belong undoubtedly, to that stock formerly wide-spread throughout Europe, and now almost confined to their island; for the character of the same race in Wales, Scotland, and Brittany, has not been, and could not be, kept so pure as in Erin; so that in our age the inhabitants of those countries have become more and more fused with their British and Gallic neighbors.
We must, therefore, at the beginning of this investigation, state briefly what we know of the Celtic race in ancient times, and examine whether the Irish of to-day do not reproduce its chief characteristics.
We do not propose, however, in the present study, referring to the physical peculiarities of the Celtic tribes; we do not know what those were two or three thousand years ago. We must confine ourselves to moral propensities and to manners, and for this view of the subject we have sufficient materials whereon to draw.
We first remark in this race an immense power of expansion, when not checked by truly insurmountable obstacles; a power of expansion which did not necessitate for its workings an uninhabited and wild territory, but which could show its energy and make its force felt in the midst of already thickly-settled regions, and among adverse and warlike nations.
As far as history can carry us back, the whole of Western Europe, namely, Gaul, a part of Spain, Northern Italy, and what we call to-day the British Isles, are found to be peopled by a race apparently of the same origin, divided into an immense number of small republics; governed patriarchally in the form of clans, called by Julius Caesar, "Civitates." The Greeks called them Celts, "Keltai." They do not appear to have adopted a common name for themselves, as the idea of what we call nationality would never seem to have occurred to them. Yet the name of Gaels in the British Isles, and of Gauls in France and Northern Italy, seems identical. Not only did they fill the large expanse of territory we have mentioned, but they multiplied so fast, that they were compelled to send out armed colonies in every direction, set as they were in the midst of thickly-peopled regions.
We possess few details of their first invasion of Spain; but Roman history has made us all acquainted with their valor. It was in the first days of the Republic that an army of Gauls took possession of Rome, and the names of Manlius and Camillus are no better known in history than that of Brenn, called by Livy, Brennus. His celebrated answer, "Vae victis," will live as long as the world.
Later on, in the second century before Christ, we see another army of Celts starting from Pannonia, on the Danube, where they had previously settled, to invade Greece. Another Brenn is at the head of it. Macedonia and Albania were soon conquered; and, it is said, some of the peculiarities of the race may still be remarked in many Albanians. Thessaly could not resist the impetuosity of the invaders; the Thermopylae were occupied by Gallic battalions, and that celebrated defile, where three hundred Spartans once detained the whole army of Xerxes, could offer no obstacle to Celtic bravery. Hellas, sacred Hellas, came then under the power of the Gauls, and the Temple of Delphi was already in sight of Brenn and his warriors, when, according to Greek historians, a violent earthquake, the work of the offended gods, threw confusion into the Celtic ranks, which were subsequently easily defeated and destroyed by the Greeks.
A branch of this army of the Delphic Brenn had separated from the main body on the frontiers of Thrace, taken possession of Byzantium, the future Constantinople, and, crossing the straits, established itself in the Heart of Asia Minor, and there founded the state of Galatia, or Gallo-Greece, which so long bore their name, and for several centuries influenced the affairs of Asia and of the whole Orient, where they established a social state congenial to their tastes and customs. But the Romans soon after invading Asia Minor, the twelve clannish republics formerly founded were, according to Strabo, first reduced to three, then to two, until finally Julius Caesar made Dejotar king of the whole country.
The Celts could not easily brook such a change of social relations; but, unable to cope against Roman power, they came, as usual, to wrangle among themselves. The majority pronounced for another chieftain, named Bogitar, and succeeded in forming a party in Rome in his favor. Clodius, in an assembly of the Roman people, obtained a decree confirmatory of his authority, and he took possession of Pessinuntum, and of the celebrated Temple of Cybele.
The history of this branch of the Celts, nevertheless, did not close with the evil fortunes of their last king. According to Justinus, they swarmed all over Asia. Having lost their autonomy as a nation, they became, as it were, the Swiss mercenaries of the whole Orient. Egypt, Syria, Pontus, called them to their defence. "Such," says Justinus, "was the terror excited by their name, and the constant success of their undertakings, that no king on his throne thought himself secure, and no fallen prince imagined himself able to recover his power, except with the help of the ever-ready Celts of those countries."
