The Principles of Gothic Design.
All the germs of Gothic architecture exist in the Romanesque of the eleventh and twelfth centuries, and became developed as the passion for more slender proportions, greater lightness, and loftiness of effect, and more delicate enrichment became marked. It is quite true that the pointed arch is universally recognised as, so to speak, the badge of Gothic, even to the extent of having suggested the title of Christian pointed architecture, by which it is often called. But the pointed arch must be regarded rather as a token that the series of changes, which, starting from the heavy if majestic Romanesque of such a cathedral as Peterborough, culminated in the gracefulness of Salisbury or Lincoln, was far advanced towards completion, than as really essential to their perfection. Many of the examples of the transition period exhibit the round arch blended with the pointed (e.g. the nave of St. David’s Cathedral or the Choir of Canterbury), and when we come to consider German architecture we shall find that the adoption of the pointed arch was postponed till long after the development of all, or almost all, the other features of the Gothic style; so as to place beyond question the existence, in that country at least, of “round arched Gothic.” Some of the best authorities have indeed proposed to employ this title as a designation for much, if not all, the round arched architecture of the west of Europe, but Scott, Sharpe, and other authorities class mediæval art down to the middle of the twelfth century under the general head of Romanesque, a course which has been adopted in this volume.
The proportions of Gothic buildings were well studied, their forms were always lofty, their gables sharp, and their general composition more or less pyramidal. Remarkable numerical relations between the dimensions of the different parts of a great Gothic cathedral can be discovered upon careful examination in most, if not all instances, and there can be little doubt that a system of geometrical proportions ran through the earlier design, and that much of the harmony and beauty which the buildings present is traceable to this fact. Independent of this the skill with which subordinate features and important ones are fitted to their respective positions, both by their dimensions and by their relative elaboration or plainness, forms a complete system of proportion, making use of the word in its broadest sense; and the results are extremely happy.
Apparent size was imparted to almost every Gothic building by the smallness, great number, and variety of its features, and by the small size of the stones employed. The effect of strength is generally, though not perhaps so uniformly, also obtained, and dignity, beauty, and harmony are rarely wanting.
Symmetry, though not altogether overlooked, has but a slender hold upon Gothic architects. It is far more observed in the interior than in the exterior of the buildings; but it must be remembered that symmetry formed the basis of many designs which, owing to the execution having been carried on through a long series of years and by different hands, came to be varied from the original intentions. Thus, for example, Chartres is a cathedral with two western towers. One of these was carried up and its spire completed in the twelfth century. The companion spire was not added till the end of the fifteenth, when men’s ideas as to the proportions, shape, ornaments, and details of a spire had altered entirely;—the later architect did not value symmetry enough to think himself bound to adhere either to the design or to the height of the earlier spire, so we have in this great façade two similar flanking towers but spires entirely unlike. What happened at Chartres happened elsewhere. The original design of buildings was in the main symmetrical, but it was never considered that symmetry was a matter so important as to require that much sacrifice should be made to preserve it.
On the other hand the subordination of a multitude of small features to one dominant one enters largely into the design of every good Gothic building; with the result that if the great governing feature or mass has been carried out in its entirety, almost any feature, no matter how irregular or unsymmetrical, may be safely introduced, and will only add picturesqueness and piquancy to the design. This is more or less a leading principle of Gothic design. A building with no irregularities, none of those charming additions which add individual character to Gothic churches, and none of the isolated features which the principle of subordination permits the architect to employ, has missed one of the chief qualities of the style. It is here that unskilled architects mostly fail when they attempt Gothic designs; they either hold on to symmetry as though they were designing a Greek temple, and they are unaware that the spirit of the style in which they are trying to work not only permits, but requires some irregular features; or if they do not fall into this error they are overtaken by the opposite one, and omit to make their irregular features subordinate to the general effect of the whole, an error less serious in its effects than the other, but still destructive of anything like the highest qualities in a building.
Repetition, like symmetry, is recognised by Gothic architecture, but not adhered to in a rigid way. No buildings gain more from the repetition of parts than Gothic churches and cathedrals; the series of pillars or piers and arches inside, the series of buttresses and windows outside, add scale to the general effect. But so long as it was in the main a series of features which broadly resembled one another, the Gothic architect was satisfied, and did not feel bound to exact repetition.
We are often, for example, surprised to find in the columns of a church an octagonal one alternating with a circular one, and almost invariably, if a series of capitals be examined, each will be discovered to differ from the others to some extent. In one bay of a church there may be a two-light window, and in the next a three-light window, and so on.
This we find in buildings erected at one time and under one architect. Where, however, a building begun at one period was continued at another (and this, it must be remembered, was the rule, not the exception, with all large Gothic buildings), the architect, while usually repeating the same features, with the same general forms, invariably followed his own predilections as to detail. There is a very good example of this in Westminster Abbey, in the western bays of the nave, which were built years later than the eastern bays. They are, to a superficial observer, identical, being of the same height and width and shape of arch, but nearly every detail differs.
