A History of Architecture in all Countries, Volume 1, 3rd ed. / From the Earliest Times to the Present Day

One of the most striking exemplifications of the perfection of the Gothic architects in this department of their art is shown in their employment of towers and spires. As a general rule, placing a tall building in juxtaposition with a low one exaggerates the height of the one and the lowness of the other; and as it was by no means the object of the architects to sacrifice their churches for their towers, it required all their art to raise noble spires without doing this. In the best designs they effected it by bold buttresses below, and the moment the tower got free of the building, by changing it to an octagon and cutting it up by pinnacles, and lastly by changing its form into that of a spire, using generally smaller parts than are found in the church. By these devices they prevented the spire from competing in any way with the church. On the contrary, a spire or group of spires gave dignity and height to the whole design, without deducting from any of its dimensions.

The city of Paris contains an instructive exemplification of these doctrines—the façade of the Cathedral of Notre Dame (exclusive of the upper storey of the towers), and the Arc de l’Etoile being two buildings of exactly the same dimensions; yet any one who is not aware of this fact would certainly estimate the dimensions of the cathedral as at least a third, if not a half, in excess of the other. It may be said that the arch gains in sublimity and grandeur what it loses in apparent dimensions by the simplicity of its parts. The façade of the cathedral, though far from one of the best in France, is by no means deficient in grandeur; and had it been as free from the trammels of utilitarianism as the arch, might easily have been made as simple and as grand, without losing its apparent size. In the other case, by employing in the arch the principles which the Gothic architects elaborated with such pains, the apparent dimensions might have been increased without detracting from its solidity, and it might thus have been rendered one of the sublimest buildings in the world.

The interior of St. Peter’s at Rome is an example of the neglect of these principles. Its great nave is divided into only four bays, and the proportions and ornaments of these, borrowed generally from external architecture, are so gigantic, that it is difficult to realise the true dimensions of the church, except by the study of the plan; and it is not too much to assert, that had a cathedral of these dimensions been built in the true Gothic style, during the 13th or 14th century, it would have appeared as if from one-third to one-half larger, and might have been the most sublime, whereas St. Peter’s is now only the largest temple ever erected.

It would be easy to multiply examples to show to what perfection the science of proportion was carried by the experimental processes above described during the existence of the true styles of architecture, and how satisfactory the result is, even upon those who are not aware of the cause; and, on the other hand, how miserable are the failures that result either from the ignorance or neglect of its rules. Enough, it is hoped, has been said to show that not only are the apparent proportions of a building very much under the control of an architect independent of its lineal dimensions, but also that he has it in his power so to proportion every part as to give value to all those around it, thus producing that harmony which in architecture, as well as in music or in painting, is the very essence of a true or satisfactory utterance.

XI.—Carved Ornament.

Architectural ornament is of two kinds, constructive and decorative. By the former is meant all those contrivances, such as capitals, brackets, vaulting shafts, and the like, which serve to explain or give expression to the construction; by the latter, such as mouldings, frets, foliage, &c., which give grace and life either to the actual constructive forms, or to the constructive decoration.

In mere building or engineering, the construction being all in all, it is left to tell its own tale in its own prosaic nakedness; but in true architecture construction is always subordinate, and as architectural buildings ought always to possess an excess of strength it need not show itself unless desired; but even in an artistic point of view it always is expedient to express it. The vault, for instance, of a Gothic cathedral might just as easily spring from a bracket or a corbel as from a shaft, and in early experiments this was often tried; but the effect was unsatisfactory, and a vaulting shaft was carried down first to the capital of the pillar, and afterwards to the floor: by this means the eye was satisfied, the thin reed-like shafts being sufficient to explain that the vault rested on the solid ground, and an apparent propriety and stability were given to the whole. These shafts not being necessary constructively, the artist could make them of any form or size he thought most proper, and consequently, instead of one he generally used three small shafts tied together at various intervals. Afterwards merely a group of graceful mouldings was employed, which satisfied not only the exigencies of ornamental construction, but became a real and essential decorative feature of the building.

In like manner it was good architecture to use flying buttresses, even where they were not essential to stability. They explained externally that the building was vaulted, and that its thrusts were abutted and stability secured. The mistake in their employment was where they became so essential to security, that the constructive necessities controlled the artistic propriety of the design, and the architect found himself compelled to employ either a greater number, or buttresses of greater strength than he would have desired had he been able to dispense with them.

The architecture of the Greeks was so simple, that they required few artifices to explain their construction; but in their triglyphs their mutules, the form of their cornices and other devices, they took pains to explain, not only that these parts had originally been of wood but that the temple still retained its wooden roof. Had they ever adopted a vault, they would have employed a totally different system of decoration. Having no constructive use whatever, these parts were wholly under the control of the architects, and they consequently became the beautiful things we now so much admire.

With their more complicated style the Romans introduced many new modes of constructive decoration. They were the first to employ vaulting shafts. In all the great halls of their Baths, or of their vaulted Basilicas, they applied a Corinthian pillar as a vaulting shaft to the front of the pier from which the arch appears to spring, though the latter really supported the vault. All the pillars have now been removed, but without at all interfering with the stability of the vaults; they were mere decorative features to explain the construction, but indispensable for that purpose. The Romans also suggested most of the other decorative inventions of the Middle Ages, but their architecture never reached beyond the stage of transition. It was left for the Gothic architects freely to elaborate this mode of architectural effect, and they carried it to an extent never dreamt of before; but it is to this that their buildings owe at least half the beauty they possess.
