of Egypt and the temples of southern India are examples of what may be done by similar means. But to effect such things, the people must be sufficiently organised to combine, and sufficiently disciplined to submit; and we have no reason to suppose that in Ireland they were either before the Christian era, and it is even very difficult to understand how they came to be so far advanced even in the time of St. Patrick. That they were so their works attest; but if we had to trust to indications derived from history alone, the inference certainly would be that the monuments are considerably more modern than the dates above assigned to them; while it seems barely possible they should be carried back to any earlier period. * * * * * There may be other rude stone monuments in Ireland besides those described or alluded to in the preceding pages, but they can scarcely be very numerous or very important, or they could hardly have escaped notice. They are not, consequently, likely to disturb any conclusion that may be arrived at from the examination of those which are known. From these, we may safely conclude that all, with perhaps the exception of the Hazlewood monument, are certainly sepulchral; and all, unless I am very much mistaken, were erected subsequently to the building of Emania by Eochaidh Ollamb Fodlha in the third century B.C. There may be cairns, and even dolmens, belonging to the earlier Hiberni before the Scoti were driven from the Continent, by the Punic or Roman wars, to seek refuge and repose in the green island of the West, but they must be insignificant, and probably must remain for ever unrecognizable. From the date, however, of the founding of Emania we seem to have a perfectly consecutive and intelligible series commencing with the smaller and ruder cairns of Lough Crew, and rising at last to the lordly sepulchres of Brugh na Boinne. Between these two stand the monuments on the battle-fields of Moytura, and contemporary with the last are the Raths on the far-famed hill of Tara. Beyond these we seem to have the tomb of the four Moels, the so-called house of Calliagh Birra, and the dolmens of Glencolumbkille, all apparently belonging to the sixth century. The tumulus at Greenmount is later than any of these, but hardly belongs to our Irish series.
