Scattered over the surface of every country in Europe may be found sepulchral monuments, the remains of pre-historic times and nations, and of a phase of life will civilisation which has long since passed away. No country in Europe is without its cromlechs and dolmens, huge earthen tumuli, great flagged sepulchres, and enclosures of tall pillar-stones. The men by whom these works were made, so interesting in themselves, and so different from anything of the kind erected since, were not strangers and aliens, but our own ancestors, and out of their rude civilisation our own has slowly grown. Of that elder phase of European civilisation no record or tradition has been anywhere bequeathed to us. Of its nature, and the ideas and sentiments whereby it was sustained, nought may now be learned save by an examination of those tombs themselves, and of the dumb remnants, from time to time exhumed out of their soil-rude instruments of clay, flint, brass, and gold, and by speculations and reasonings founded upon these archaeological gleanings, meagre and sapless.
