Myths and Legends of the Celtic Race [EPUB ebook] 

The Past may be forgotten, but it never dies. The elements which in the most remote times have entered into a nation’s composition endure through all its history, and help to mould that history, and to stamp the character and genius of the people.
The examination, therefore, of these elements, and the recognition, as far as possible, of the part they have actually contributed to the warp and weft of a nation’s life, must be a matter of no small interest and importance to those who realise that the present is the child of the past, and the future of the present; who will not regard themselves, their kinsfolk, and their fellow-citizens as mere transitory phantoms, hurrying from darkness into darkness, but who know that, in them, a vast historic stream of national life is passing from its distant and mysterious origin towards a future which is largely conditioned by all the past wanderings of that human stream, but which is also, in no small degree, what they, by their courage, their patriotism, their knowledge, and their understanding, choose to make it.
