Joep Leerssen, Remembrance and Imagination: Patterns in the Historical and Literary Representation of Ireland in the Nineteenth Century (Cork UP/Field Day 1996) - writes: Canon Bourke’ Aryan Origin of the Gaelic Race and Language (1875) ‘was an attempt to reconcile native Milesian mythography, as expounded by Keating, with the insights of modern science and philology.

[Here quotes title-details of the work - as given under Quotations, infra.]

Bourke firmly believes in the native/biblical derivation of the Gaels from Magog, son of Japhet; at the samesame time he tries to bring this nativist scheme into accord with the progress of science by calling this Oriental (Jewish!) origin Aryan, and in the process he extensively summarizes the progress of comparative historical sciences as marked by the names of Max Müller, Matthew Arnold, Prichard, Picter, Henry Maine; within the Irish scholarly framework, Bourke is most fulsome in his praise (paradoxically enough) for the factualist archaeologists and philologists: Petrie, O’Donovan and O’Curry (11, 48-50).

Further (Leerssen, 1996): ‘Accordingly Bourke attempts to square Petrie’s ecclesiastical theory with his own Milesian ancestry myth, and advances the notion that the towers were buit in Pagan times and later converted to Christian purposes. His book, which comes from a Catholic, populist-nationalist background, is also indirect testimony to the extent to which the middle classes had been left bewildered by by the entire tradition of conflicting interpretations.

[Here quotes Preface from Aryan Origin - as infra.]

‘Here, then, is a book evidently aimed at popularizing knowledge and insights from the historical sciences to a non-professional audience; and we see that that audience is left to acquiesce in the mythical version of Irish history to a far greater extent than was warranted by rigorous scholarship. By 1875, the Catholic middle classes with a national interest (the readership of Canon Bourke) were taking cognizance of the scientific achievements of Petrie without abandoning the colourful appeal ofthe Milesian origin-myth as it had been [140] handed on and watered down from Keating to Moor to Denis Florence MacCarthy. This type of history was to be fed to the American-Irish market, with “Histories” like those of Haverty and A. M. Sullivan but also the underlying imaginative mind-set of which Canon Bourke himself was such a prominent representative. [...] Bourke attempted to accommodate Milesian myth within the terms of positive scholarship is therefore no mere idiosyncrasy;; it bespeaks a tendency [...] that pre-scientific thought and mythical lore concerning the past survived their scholarship disestablishment and maintained their currency within Irish historical consciousness and irish national thought at large. [...] Round Towers were beginning to be manufactured to suit nineteenth-century taste and attitudes.! (pp.139-40.)

Since this edition has been put to press, one of the greatest Irish Scholars of the present or any former century has passed away—the learned and the lamented John O’Donovan, LL.D. A cycle of years will not repay to tho cause of Celtic literature the loss it has sustained in his death. May his memory be ever dear to every lover of ancient lore and real learning.
 His was the master-hand which first moulded into philological and philosophical form and fullness the chaotic mass into which persecution for ages past, and consequent inability of Irishmen at home to attend to its preservation, much less to its literary cultivation, had reduced their mother-tongue; a tongue which has been pronounced by a linguistic lover to be as clear as Latin, flexible and harmonious as Greek, stately as Spanish, soft as Italian, fluent as French, and expressive as German. Dr. O’Donovan’s work infused into the written speech of the Gael spirit and life, which length of time alone can extinguish.
 Although he did much, yet—no wonder—he left much undone; and though he laboured for the cause of the people’s language, the many had not been enabled to profit by his labours.
 The College Grammar was written and published for the sake of the many, and to improve, as best one could, the literary character of the vernacular speech. On its first appearance the work was favourably noticed by the learned. Being now entirely re-cast, the present edition - embracing the [ii] results of observations made during the last six years through the provinces on the spoken dialects, and in works published and unpublished on the written speech - cannot fail to be of much additional service to the student and the savant.
  To lament, like hireling mourners, the loss of the language of the past, and at the same time, to neglect or decry the living, spoken language of the present, bespeaks insincerity at heart, and proves such flippant eulogists of the Gaelic to be actuated for its preservation or advancement only by that kind of regard for which step-mothers are proverbial. Good wishes without practice are like like flowers without fruit.
