“The whole system of symbolism impressed on the art and the life of the Middle Ages must awaken the admiration of poets in all times. In reality, what colossal unity there is in Christian art, especially in its architecture! These Gothic cathedrals, how harmoniously they accord with the worship of which they are the temples, and how the idea of the Church reveals itself in them! Everything about them strives upwards, everything transubstantiates itself; the stone buds forth into branches and foliage, and becomes a tree; the fruit of the vine and the ears of corn become blood and flesh; the man becomes God; God becomes a pure spirit. For the poet, the Christian life of the Middle Ages is a precious and inexhaustibly fruitful field. Only through Christianity could the circumstances of life combine to form such striking contrasts, such motley sorrow, such weird beauty, that one almost fancies such things can never have had any real existence, and that it is all a vast fever-dream the fever-dream of a delirious deity. Even Nature, during this sublime epoch of the Christian religion, seemed to have put on a fantastic disguise; for oftentimes though man, absorbed in abstract subtilties, turned away from her with abhorrence, she would recall him to her with a voice so mysteriously sweet, so terrible in its tenderness, so powerfully enchanting, that unconsciously he would listen and smile, and become terrified, and even fall sick unto death.”
