thought of his own country and those of the Orient. Similar conclusions had forced themselves upon older people who did not possess a tithe of his Eastern lore. Moore, that versatile Anacreontic, in his ill-fitting disguise of an Edinburgh Reviewer, avowed “That there exist strong traces of an Oriental origin in the language, character, and movements of the Irish people, no fair inquirer into the subject will be inclined to deny;” and it is further instanced by the same reviewer how the famous traveller, Bishop Pococke, on visiting Ireland after his return from the East, was much struck with “the amazing conformity” he observed between the Irish and the Egyptians.[6] From early childhood the questions to which we have referred seem to have been present to O’Brien--even from the time when he gazed upon the stunted ruin of Bally-Carbery Round Tower, not far from his father’s house, and had been told by awestruck peasants that the real name of that desolate and unsightly object was _Cathoir Ghall_, or “The Temple of Delight” (p. 48). Since then he had seen other and complete round towers; had noticed that all were of the same peculiar shape, and possibly had detected for himself, or learned from other sources, the existence of that phallic analogy upon which he so strongly insists. He must have read in Sir William Jones and elsewhere how, in Eastern lands, the idea which lay beneath this same analogy formed the basis of a widespread religious faith, and was expressed in structures devoted to public worship. His next step was, almost inevitably, one of conjecture. If, as the voice of national tradition asserted, the round towers are “temples,” and if certain analogous associations are connected with them, might they not have been temples of a kindred religious belief? Having settled this to his own satisfaction, the speculation would naturally rise--How came that particular form of belief to prevail in Ireland? Was it native to the soil; or if not, by whom was it introduced, and when? His book being mainly an answer to these questions, we need not continue to follow the various stages by which conjecture may have passed into theory, and theory into conviction. With men of O’Brien’s temperament the hypothetical interval is rarely of long duration. Before he had assumed the _toga virilis_ of a full-fledged graduate, he probably felt confident that in an Eastern origin lay the true solution of the mystery of the round towers; and the more he studied the subject, the stronger grew his belief. Being an ambitious man, too, he had no intention to forego the honour which he was persuaded must accrue to the discoverer of this key to a problem that had baffled so many generations of inquirers, and longed for an opportunity to display his acquisition.
