The various nations who attained eminence in the arts before the time of Christ, each of them, produced forms of architecture which in their various degrees of merit were almost exactly indicative of the degrees of intellectual and moral energy of the nations which originated them; and each reached its greatest perfection at the time when the true energy and prosperity of the people who had invented it were at their culminating point. Many of these various styles of architecture were good, considered in relation to the times and races which gave birth to them; but none were absolutely good or perfect, or fitted for the practice of all future time.

The advent of Christianity for the first time rendered possible the full development of the soul of man, and therefore the full development of the arts of man.

Christianity gave birth to a new architecture, not only immeasurably superior to all that had preceded it, but demonstrably the best architecture that can exist; perfect in construction and decoration, and fit for the practice of all time.

This architecture, commonly called “Gothic,” though in conception perfect, like the theory of a Christian character, never reached an actual perfection, having been retarded and corrupted by various adverse influences; but it reached its highest perfection, hitherto manifested, about the close of the thirteenth century, being then indicative of a peculiar energy in the Christian mind of Europe.

In the course of the fifteenth century, owing to various causes which I have endeavored to trace in the preceding pages, the Christianity of Europe was undermined; and a Pagan architecture was introduced, in imitation of that of the Greeks and Romans.

The architecture of the Greeks and Romans themselves was not good, but it was natural; and, as I said before, good in some respects, and for a particular time.

But the imitative architecture introduced first in the fifteenth century, and practised ever since, was neither good nor natural. It was good in no respect, and for no time. All the architects who have built in that style have built what was worthless; and therefore the greater part of the architecture which has been built for the last three hundred years, and which we are now building, is worthless. We must give up this style totally, despise it and forget it, and build henceforward only in that perfect and Christian style hitherto called Gothic, which is everlastingly the best.

This is the theorem of these volumes.

In support of this theorem, the first volume contains, in its first chapter, a sketch of the actual history of Christian architecture, up to the period of the Reformation; and, in the subsequent chapters, an analysis of the entire system of the laws of architectural construction and decoration, deducing from those laws positive conclusions as to the best forms and manners of building for all time.
