There is an art of the flood, the art of Titian when his Ariosto, and his Bacchus and Ariadne, give new images to the dreams of youth, and of Shakespeare when he shows us Hamlet broken away from life by the passionate hesitations of his reverie. And we call this art poetical, because we must bring more to it than our daily mood if we would take our pleasure; and because it delights in picturing the moment of exaltation, of excitement, of dreaming (or in the capacity for it, as in that still face of Ariosto's that is like some vessel soon to be full of wine). And there is an art that we call real, because character can only express itself perfectly in a real world, being that world's creature, and because we understand it best through a delicate discrimination of the senses which is but entire wakefulness, the daily mood grown cold and crystalline. We may not find either mood in its purity, but in mainly tragic art one distinguishes devices to exclude or lessen character, to diminish the power of that daily mood, to cheat or blind its too clear perception. If the real world is not altogether rejected, it is but touched here and there, and into the places we have left empty we summon rhythm, balance, pattern, images that remind us of vast passions, the vagueness of past times, all the chimeras that haunt the edge of trance; and if we are painters, we shall express personal emotion through ideal form, a symbolism handled by the generations, a mask from whose eyes the disembodied looks, a style that remembers many masters, that it may escape contemporary suggestion; or we shall leave out some element of reality as in Byzantine painting, where there is no mass, nothing in relief, and so it is that in the supreme moment of tragic art there comes upon one that strange sensation as though the hair of one's head stood up. And when we love, if it be in the excitement of youth, do we not also, that the flood may find no stone to convulse, no wall to narrow it, exclude character or the signs of it by choosing that beauty which seems unearthly because the individual woman is lost amid the labyrinth of its lines as though life were trembling into stillness and silence, or at last folding itself away? Some little irrelevance of line, some promise of character to come, may indeed put us at our ease, 'give more interest' as the humour of the old man with the basket does to Cleopatra's dying; but should it come as we had dreamed in love's frenzy to our dying for that woman's sake, we would find that the discord had its value from the tune.
