These dreams, antiquities, traditions, once actual, living, and historical, have passed from the world of sense into the world of memory and thought: and time, it seems to me, has not taken away from their power, nor made them more remote from sympathy, but has rather purified them by removing them from earth to heaven: from things which the eye can see and the ear can hear they have become what the heart ponders over, and are so much nearer, more familiar, more suitable for literary use than the day they were begotten. They have now the character of symbol, and, as symbol, are more potent than history. They have crept through veil after veil of the manifold nature of man; and now each dream, heroism, or beauty has laid itself nigh the divine power it represents, the suggestion of which made it first beloved: and they are ready for the use of the spirit, a speech of which every word has a significance beyond itself, and Deirdre is, like Helen, a symbol of eternal beauty; and Cuculain represents as much as Prometheus the heroic spirit, the redeemer in man. In so far as these ancient traditions live in the memory of man, they are contemporary to us as much as electrical science: for the images which time brings now to our senses, before they can be used in literature, have to enter into exactly the same world of human imagination as the Celtic traditions live in. And their fitness for literary use is not there determined by their freshness but by their power of suggestion. Modern literature, where it is really literature and not book-making, grows more subjective year after year, and the mind has a wider range over time than the physical nature has. Many things live in it--empires which have never crumbled, beauty which has never perished, love whose fires have never waned: and, in this formidable competition for use in the artist's mind, today stands only its chance with a thousand days. To question the historical accuracy of the use of such memories is not a matter which can be rightly raised. The question is--do they express lofty things to the soul? If they do they have justified themselves.
