If any one insists that such was not the case, he must of necessity admit that the oral teaching of the Ollamhs was so perfect and so universally current in the same formulas all over the island, that such oral teaching really took the place of writing; and in this case, also, which is scarcely possible, however, Ireland had an authentic history. This last supposition, certainly, can hardly be credited; and yet, if the first be rejected, it must be admitted, since it cannot be imagined that subsequent Irish historians, numerous as they became in time, could have agreed so well together, and remained so consistent with themselves, and so perfectly accurate in their descriptions of places and things in general, without anterior authentic documents of some kind or other, on which they could rely. Any person who has merely glanced at the astonishing production called the "Annals of the Four Masters," must necessarily be of this opinion. In no nation in the world are there found so many old histories, annals, chronicles, etc., as among the Irish; and that fact alone suffices to prove that in periods most ancient they were truly a civilized nation, since they attached such importance to the records of events then taking place among them. But the Irish were, moreover, a branch of the great Celtic race, whose renown for wisdom, science, and valor, was spread through all parts, particularly among the Greeks. The few details we purpose giving on the subject will convince the reader that among the nations of antiquity they held a prominent position; and not only were they possessed of a civilization of their own, not despicable even in the eyes of a Roman--of the great Julius himself--but they were ever most susceptible of every kind of progress, and consequently eager to adopt all the social benefits which their intercourse with Rome brought them. At least, they did so as soon as, acknowledging the superior power of the enemy, they had the good sense to feel that it was all-important to imitate him. Hence sprang that Gallo-Roman civilization which obtained during the first five or six centuries of the Christian era--a civilization which the barbarians of the North endeavored to destroy, but to which they themselves finally yielded, by embracing Christianity, and gradually changing their language and customs. Everywhere--in Gaul, Italy, Britain, and Ireland--did the Celts manifest that susceptibility to progress which is the invariable mark of a state antagonistic to barbarism. In this they totally differed from the Vandals and Huns, whom it took the Church such a dreary period to conquer, and whom no other power save the religion of Christ could have subdued. These few words are sufficient for our present purpose. We proceed to show that, in their stubborn opposition to many a current of European opinion, they acted rightly.
