It is not attaching too high a degree of importance to the study of Celtic antiquities, to maintain, that, owing to the attention now paid to it in this country, a light begins to break in upon that part of ancient history, which, beyond every other, seemed to present a forlorn investigation. All that relates to the aboriginal inhabitants of the north of Europe, would be involved in darkness but for the enquiries now instituted respecting Celtic sepulchres. From the information already received, concerning these sepulchres, it may be assumed, as a fact almost capable of actual demonstration, that the mounds, or barrows, common to all Great Britain, and to the neighbouring continent, together with all the tumuli fabled by Grecian and by Roman historians as the tombs of Giants, are so many several vestiges of that mighty family of Titan-Celts who gradually possessed all the eastern shores of the Mediterranean, and who extended their colonies over all the countries where Cyclopéan structures may be recognized; whether in the walls of Crotona, or the temple at Stonehénge; in the Cromlechs of Wales, or the trilithal monuments of Cimbrica Chersonesus; in Greece, or in Asia-Minor; in Syria, or in Egypt. It is with respect to Egypt alone, that an exception might perhaps be required; but history, while it deduces the origin of the worship of Minerva, at Sais, from the Phrygians, also relates of this people, that they were the oldest of mankind. The Cyclopéan architecture of Egypt may therefore be referred originally to the same source; but, as in making the following Observations brevity must be a principal object, it will be necessary to divest them of every thing that may seem like a Dissertation; and confine the statement, here offered, to the simple narrative of those facts, which have led to its introduction.
