Early Bardic Literature, Ireland

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.
