{14} Here again let me have the pleasure of quoting Lord Strangford:—‘When the Celtic tongues were first taken in hand at the dawn of comparative philological inquiry, the tendency was, for all practical results, to separate them from the Indo-European aggregate, rather than to unite them with it. The great gulf once fixed between them was narrowed on the surface, but it was greatly and indefinitely deepened. Their vocabulary and some of their grammar were seen at once to be perfectly Indo-European, but they had no case-endings to their nouns, none at all in Welsh, none that could be understood in Gaelic; their _phonesis_ seemed primeval and inexplicable, and nothing could be made out of their pronouns which could not be equally made out of many wholly un-Aryan languages. They were therefore co-ordinated, not with each single Aryan tongue, but with the general complex of Aryan tongues, and were conceived to be anterior to them and apart from them, as it were the strayed vanguard of European colonisation or conquest from the East. The reason of this misconception was, that their records lay wholly uninvestigated as far as all historical study of the language was concerned, and that nobody troubled himself about the relative age and the development of forms, so that the philologists were fain to take them as they were put into their hands by uncritical or perverse native commentators and writers, whose grammars and dictionaries teemed with blunders and downright forgeries. One thing, and one thing alone, led to the truth: the sheer drudgery of thirteen long years spent by Zeuss in the patient investigation of the most ancient Celtic records, in their actual condition, line by line and letter by letter. Then for the first time the foundation of Celtic research was laid; but the great philologist did not live to see the superstructure which never could have been raised but for him. Prichard was first to indicate the right path, and Bopp, in his monograph of 1839, displayed his incomparable and masterly sagacity as usual, but for want of any trustworthy record of Celtic words and forms to work upon, the truth remained concealed or obscured until the publication of the _Gramatica Celtica_. Dr. Arnold, a man of the past generation, who made more use of the then uncertain and unfixed doctrines of comparative philology in his historical writings than is done by the present generation in the fullest noonday light of the _Vergleichende Grammatik_, was thus justified in his view by the philology of the period, to which he merely gave an enlarged historical expression. The prime fallacy then as now, however, was that of antedating the distinction between Gaelic and Cymric Celts.’ {25} Dr. O’Conor in his _Catalogue of the Stowe MSS._ (quoted by O’Curry). {26} O’Curry. {29} Here, where Saturday should come, something is wanting in the manuscript.
