Now, as the Gothic spirit is made up of several elements, some of which may, in particular examples, be wanting, so the Gothic form is made up of minor conditions of form, some of which may, in particular examples, be imperfectly developed.

We cannot say, therefore, that a building is either Gothic or not Gothic in form, any more than we can in spirit. We can only say that it is more or less Gothic, in proportion to the number of Gothic forms which it unites.

§ LXXX. There have been made lately many subtle and ingenious endeavors to base the definition of Gothic form entirely upon the roof-vaulting; endeavors which are both forced and futile: for many of the best Gothic buildings in the world have roofs of timber, which have no more connexion with the main structure of the walls of the edifice than a hat has with that of the head it protects; and other Gothic buildings are merely enclosures of spaces, as ramparts and walls, or enclosures of gardens or cloisters, and have no roofs at all, in the sense in which the word “roof” is commonly accepted. But every reader who has ever taken the slightest interest in architecture must know that there is a great popular impression on this matter, which maintains itself stiffly in its old form, in spite of all ratiocination and definition; namely, that a flat lintel from pillar to pillar is Grecian, a round arch Norman or Romanesque, and a pointed arch Gothic.

And the old popular notion, as far as it goes, is perfectly right, and can never be bettered. The most striking outward feature in all Gothic architecture is, that it is composed of pointed arches, as in Romanesque that it is in like manner composed of round; and this distinction would be quite as clear, though the roofs were taken off every cathedral in Europe. And yet, if we examine carefully into the real force and meaning of the term “roof” we shall perhaps be able to retain the old popular idea in a definition of Gothic architecture which shall also express whatever dependence that architecture has upon true forms of roofing.

§ LXXXI. In [Chap. XIII.] of the first volume, the reader will remember that roofs were considered as generally divided into two parts; the roof proper, that is to say, the shell, vault, or ceiling, internally visible; and the roof-mask, which protects this lower roof from the weather. In some buildings these parts are united in one framework; but, in most, they are more or less independent of each other, and in nearly all Gothic buildings there is considerable interval between them.

Now it will often happen, as above noticed, that owing to the nature of the apartments required, or the materials at hand, the roof proper may be flat, coved, or domed, in buildings which in their walls employ pointed arches, and are, in the straitest sense of the word, Gothic in all other respects. Yet so far forth as the roofing alone is concerned, they are not Gothic unless the pointed arch be the principal form adopted either in the stone vaulting or the timbers of the roof proper.

I shall say then, in the first place, that “Gothic architecture is that which uses, if possible, the pointed arch in the roof proper.” This is the first step in our definition.

§ LXXXII. Secondly. Although there may be many advisable or necessary forms for the lower roof or ceiling, there is, in cold countries exposed to rain and snow, only one advisable form for the roof-mask, and that is the gable, for this alone will throw off both rain and snow from all parts of its surface as speedily as possible. Snow can lodge on the top of a dome, not on the ridge of a gable. And thus, as far as roofing is concerned, the gable is a far more essential feature of Northern architecture than the pointed vault, for the one is a thorough necessity, the other often a graceful conventionality: the gable occurs in the timber roof of every dwelling-house and every cottage, but not the vault; and the gable built on a polygonal or circular plan, is the origin of the turret and spire;[69] and all the so-called aspiration of Gothic architecture is, as above noticed (Vol. I. [Chap. XII.] § VI.), nothing more than its developement. So that we must add to our definition another clause, which will be, at present, by far the most important, and it will stand thus: “Gothic architecture is that which uses the pointed arch for the roof proper, and the gable for the roof-mask.”

§ LXXXIII. And here, in passing, let us notice a principle as true in architecture as in morals. It is not the compelled, but the wilful, transgression of law which corrupts the character. Sin is not in the act, but in the choice. It is a law for Gothic architecture, that it shall use the pointed arch for its roof proper; but because, in many cases of domestic building, this becomes impossible for want of room (the whole height of the apartment being required everywhere), or in various other ways inconvenient, flat ceilings may be used, and yet the Gothic shall not lose its purity. But in the roof-mask, there can be no necessity nor reason for a change of form: the gable is the best; and if any other—dome, or bulging crown, or whatsoever else—be employed at all, it must be in pure caprice, and wilful transgression of law. And wherever, therefore, this is done, the Gothic has lost its character; it is pure Gothic no more.
