"The proof of the endowment of a true artist is always to be found in the fact that his work of art expresses the general will of a period. Perhaps that is most clearly shown in architecture .... The religious mystical world of the Christian Middle Ages, turning inwards upon itself, found forms of expression which were possible only for that world. A Gothic stadium is as unthinkable as a Romanesque railway station or a Byzantine market hall. The way in which the artist of the Middle Ages, of the beginnings of the modern world, found the artistic solution for the buildings which he was commissioned to create is in the highest degree striking and admirable. That way, however, is no evidence that the conception of the content of life held by the folk of his day was in itself either absolutely right or absolutely wrong. It is evidence only that works of art have rightly mirrored the inner mind of a past age. It is therefore quite comprehensible that insofar as the attempt is made to carry on the life of that past age, those who search for solutions of artistic problems can still seek and find there fruitful suggestions."
