architecture up to the fifteenth century was the principal record of mankind; during that time no concept of any complexity appeared in the world which was not made into a building; every popular idea like every religious law has had its monuments; finally, the human race never had an important thought which it did not write down in stone. And why? Because every thought, be it religious or philosophical, has an interest in perpetuating itself, an idea which has stirred one generation wants to stir others and leave its mark.
