All aspects of the life of an age are interrelated, even when the interrelations express themselves in cross purposes and intellectual dissolution. Whether or not they embody forms and ideas worthy to be dignified by the name of architecture, the buildings of any period are an expression of it. They reflect, in varying degrees, its economic and social development, the enactments of its legislative bodies, the acts of its administrative officials, the decisions of its law courts, the character and course of its wars. They also express, again in varying degrees, its methods of education, its religious life, its natural science, its thought and its art. They are, to some extent, the expression of past traditions and works of the mind which have retained a hold on the life of the period or have been revived by its thinkers and artists, as classical antiquity has been revived again and again in Western European history since the eleventh century.
