It seems a solecism in the intellectual history of man to discover among such a semi-barbarous people a government of sages, who, we are assured, "invented and taught such philosophy and other learning as were never read of nor heard of by any men before."[6] This paradoxical incident deepens in mystery when we are to be taught that the druidical institution of Britain was Pythagorean, or patriarchal, or Brahminical. The presumed encyclopedic knowledge which this order possessed, and the singular customs which they practised, have afforded sufficient analogies and affinities to maintain the occult and remote origin of Druidism. Nor has this notion been the mere phantom of modern system-makers. It was a subject of inquiry among the ancients whether the Druids had received their singular art of teaching by secret initiation, and the prohibition of all writing, with their doctrine of the pre-existence and transmigration of souls, from Pythagoras; or, whether this philosopher in his universal travels had not alighted among the Druids, and had passed through their initiation?[7] This discussion is not yet obsolete, and it may still offer all the gust of novelty. A Welsh antiquary, according to the spirit of Welsh antiquity, insists that the Druidical system of the Metempsychosis was conveyed to the Brahmins of India by a former emigration from Wales; but the reverse may have occurred, if we trust the elaborate researches which copiously would demonstrate that the Druids were a scion of the oriental family.[8] Every point of the Druidical history, from its mysterious antiquity, may terminate with reversing the proposition. A recent writer confidently intimated that the knowledge of Druidism must be searched for in the Talmudical writings; but another, in return, asserts that the Druids were older than the Jews. Whence and when the British Druids transplanted themselves to this lone world amid the ocean, bringing with them all the wisdom of far antiquity, to an uncivilized race, is one of those events in the history of man which no historian can write. It is evident that they long preserved what they had brought; since the Druids of Gaul were fain to resort to the Druids of Britain to renovate their instruction. The Druids have left no record of themselves; they seem to have disdained an immortality separate from the existence of their order; but the shadow of their glory is reflected for ever in the verse of Lucan, and the prose of Cæsar. The poet imagined that if the knowledge of the gods was known to man, it had been alone revealed to these priests of Britain. The narrative of the historian is comprehensive, but, with all the philosophical cast of his mind and the intensity of his curiosity, Cæsar was not a Druid;[9] and only a Druid could have written--had he dared!--on DRUIDHEACHT--a sacred, unspeakable word at which the people trembled in their veneration.
