Arch (architecture)

“ Sometimes the stalactite roofs are lofty, sometimes we have to bend our heads in order to pass from one vaulted chamber to another; here we have a superb column supporting an arch; here a pillar in course of formation, everywhere the strangest, most fantastic architecture, an architecture moreover that is the work of ages; one petrifying drop after another doing its apportioned work, column, arch, and roof being formed by a process so slow that the life-time of a human being hardly counts in the calculation. ”

“ Norman architecture is in the use of the pointed form of arch, yet in the study of the early buildings of this date it is curious to notice how evenly the balance is held between the pointed and the round arch, and how at one time it was quite an open question whether the Gothic style would be distinguished by a round or a pointed arch. ”

“ The second half of the 12th century was a period of rapid development of architectural forms in the direction of increased elegance and refinement. The pointed arch employed at first for the arches of construction entirely superseded the semicircular arch in doorways, windows and arcades by the end of the century and its adoption finally solved the problem of vaulted construction. The abutting arches under the triforium roofs of the earlier churches were developed into flying buttresses above the roofs springing from buttresses of increased projection and weighted by pinnacles. ”

“ The horizontal cornice, so characteristic of Greek and Early Roman architecture is of frequent occurrence, the round arch was long retained in combination with pointed highly-pitched roofs, and spires are rare, whilst the beautiful groined vaulting, the flying buttresses, and the exquisite window-tracery, that lend so great a charm to the cathedrals and churches of France and England, are very seldom met with. ”

“ These still are left, exhibiting external and internal ranges of arches, springing directly from the capitals of the columns, without any intervening entablature. What more, we ask, is wanting here, to one of the most decided characteristics of one species, at least, of Gothic architecture, and an elemental principle in all kinds? nothing, save a little less elegance of workmanship in the supports, a pier substituted for the column, and the soffit of the arch bevelled instead of being square; steps successively apparent in posterior remains. ”

“ The whole tendency, too, of the onward movement of the art was towards increased height; and, while walls and pillars might avail themselves to the full of this upward striving, it was hard that the arch—the very essence of the style—should be condemned to unalterable stuntiness. Proportion evidently claimed that the arch should have its fair share in the increasing height of the buildings, yet the inexorable semicircle said, “Nay, my proportions are fixed. You may lengthen your straight lines as you please; but by no law of science can my height exceed one-half of my width.” ”

“ Thus we see that the adoption of the arched system of construction, unbiassed by any pre-existing laws of art, but aided only by the very rational desire to utilise the materials most abundantly provided by nature, led to two of the most important characteristics common to Romanesque and Gothic architecture, viz., the sub-ordinated arch and the clustered column, with the whole system of decoration derived from them; than which no two features can be pointed out which have been more richly fruitful of architectural forms the most original and beautiful. ”

“ The forms of the villas to which these towers are attached are straggling, and varied by many crossing masses; but the great principle of simplicity is always kept in view, everything is square and terminated by parallel lines; no tall chimneys, no conical roofs, no fantastic ornaments are ever admitted: the arch alone is allowed to relieve the stiffness of the general effect. ”

“ The essential quality of the arch, it is elasticity. The wider it is, the broader the space which it must cross is, and the more necessary it is that it is flexible. The manufacturers of the Middle Ages followed this principle perfectly by multiplying the joints in their archs, by composing them of equal archstones, always extradossés carefully. ”

“ The types which I found in nature or in practice are of the stalactitic, dome, and arch,—the horseshoe arch, the tracery on the wall, the diversified colouring of that tracery, the half-globe dome upon the cube; and these, in fact, are the modifications that the architecture of Judæa received, and by which it has been converted into the Moorish.
On the material the system of architecture depended, and it is wholly different from the classic. The great styles of antiquity depended, not on the adhesion of the stones, but their form and weight, and by science alone they obtained arches. ”

“ DISCHARGING ARCH, in architecture, an arch built over a lintel or architrave to take off the superincumbent weight. The earliest example is found in the Great Pyramid, over the lintels of the entrance passage to the tomb: it consisted of two stones only, resting one against the other. ”

“ Below, the ceilings of the arch and corridors are brilliant from concealed lights placed within them.

Triumphal Arch, The Rising Sun
The triumphal arches which by night gain in majesty and mysterious power, by day have the added beauty of the color manipulation and decorative treatment, which is exceedingly rich and varied.
The twisted columns of Sienna marble which flank the arch, two on either side, are composite, mingling Corinthian and Ionic elements. Each column is crowned with a sculptured figure, representing the "Angel of Peace" by Leo Lentelli. ”

“ The nave arcades generally sprang from piers (Fig. 170) , more rarely from columns. Arches are constantly met with recessed, i.e. in receding planes, [35] the first stage of progress towards a Gothic treatment, and are occasionally slightly moulded (Fig. 171) . Western doorways are often highly enriched with sculpture; and the carving and sculpture generally, though often rude, are full of vitality. Towers occur, usually square, more rarely octagonal. Window-lights are frequently grouped two or more under one arch. ”

“ The progress in architecture among the nations of ancient civilization was quite rapid. Massive structures were built for capacity and strength, which the natives soon learned to {100} decorate within and without. The buildings were made of large blocks of hewn stone, fitted together mechanically by the means of cement, which made secure foundations for ages. When in the course of time the arch was discovered, it alone became a power to advance the progress of architecture. We have seen pass before our eyes a sudden transition in dwelling houses. ”

“ Q. What difference is there between the arches of this style, which support the clerestory, and those of an earlier period?
A. The lancet arch is seldom seen; the equilateral arch is generally, though not always, used. Both this and the obtuse-angled arch are, taken exclusively, difficult to be distinguished from those of an earlier period. In small buildings the edges of the pier arches are plain and chamfered. In large churches a series of quarter-round or roll-mouldings, which have often a square-edged fillet attached, are applied to the sub-arch, edges, and facing. ”

“ A triumphal arch scheme with an Ionic order, a Tudor arch, no openings in the lateral bays, and no attic, is surmounted with a Greek temple front of an engaged Corinthian order raised on tall pedestals connected by an engaged balustrade. This embraces in width only the central bay of the substructure, and solid abutments of concave outline are carried up over the side bays. A plain attic over the pediment of the temple forms the base for a square pyramid intersected by a tall hexagon, surmounted with a hexagonal dome. ”

“ The constructive value of Gothic architecture is, however, far greater than that of Romanesque, as the pointed arch is not only susceptible of an infinite variety of forms and applications to the weight to be sustained, but it possesses, in the outline given to its masonry at its perfect periods, the means of self-sustainment to a far greater degree than the round arch. ”

“ Another sure sign of lingering Gothic influence is where the round arch is fringed with cusping.
The more typically Renaissance form of design is where a huge monumental structure fills the greater part of the window, [Pg 348] not canopying a subject, but having in front of it a figure group (Transept of S. Gudule, page 71) . The foreground figures stand out in dark relief against the architecture and the sky beyond, seen through the central arch. Into this grey-blue merges very often a distant landscape, painted in great part upon the blue, and really seeming to recede into the distance. ”

“ In each bay of the ground story is a deep round-arched rectangular recess in the thickness of the wall, and over each of these an open gallery with two colonnettes and two small jamb pilasters carrying an entablature over each of the lateral spaces so formed, and an arch over the central one, an early instance of a form of compound opening that was much used in the architecture of the later Renaissance. ”

“ The outer round arch of the door is thrown across between the two buttresses, which for more than half their height are covered with carved and twisted mouldings, with niches, canopies, corbels, and statues all carved with the utmost elaboration. Immediately above the great arch is a round-headed window, and on either side between it and the buttresses are two rows of statues and niches in tiers separated by elaborate statue-bearing shafts and pinnacles. Statues even occupy niches on the window jamb, and a Virgin and Child stand up in front on the end of the ogee drip-mould of the great arch. ”

“ And that therefore Gothic ornamentation is nobler than Greek ornamentation, and Gothic architecture the only architecture which should now be built.
58. Proposition 1st.—Gothic or Romanesque construction is nobler than Greek construction. [20] That is to say, building an arch, vault, or dome, is a nobler and more ingenious work than laying a flat stone or beam over the space to be covered. It is, for instance, a nobler and more ingenious thing to build an arched bridge over a stream, than to lay two pine-trunks across from bank to bank ”

“ A triple archway gives entrance to the three naves of the cathedral; the central arch fronts the principal nave, and the smaller arches (to the north and south) , the two collateral{108} naves, or, as some would call them, the side aisles. These three arches and their tympana are covered with statues which have been adapted to the architecture with such skill that at a little distance they appear to be carved out of the actual material of which the arches are composed. Examined closely, every statue, every ornament is a masterpiece of delicate sculpture. ”

“ Later structural changes were the erection of an arch above the altar, the heightening of the nave, the connecting of the columns between the nave and aisles by arches instead of horizontal architraves, the introduction of windows, to which the collective name of the clerestory or the clear-story was given, in the semicircular heads of the arches and more rarely into the upper part of the low external walls of the aisles, the apse, which was gradually lengthened eastwards, being left comparatively dark, the only light proceeding from the main body of the church. ”

“ The line from the roll to the upright face of the arch is also inclined to that face instead of being at right angles with it, as it usually was in early profiles, and thus the flat surfaces are greatly lessened, and the effect of the whole is materially lightened. ”

“ The proportions of the internal elevation are such that, if the entire height of the wall be divided into nine parts, four go to the main arcade, two to the triforium or gallery, and three to the clerestory (Fig. 253) .
Fig. 253.—Sectional view of Nave, St. Alban’s.
The arches of each are of three orders, and are, for the most part, without shafts; the section of the jamb and arch being the same, severed only by a simple{102} impost. A broad pilaster buttress runs up the face of each pier from floor to ceiling. ”

“ It was at first used for the main arch only of the greater vault. The same reason soon led to its introduction wherever great weight was to be carried, as under towers, etc.; but for all small arches the semicircle was long retained. I have alluded to the very beautiful theory that it was introduced for the side arches of oblong groins, simply as a means of obtaining arches of equal height with only half the span with those of the main vault. ”

“ The arches are ogee trefoils cusped, and their spandrels are clumsily filled with enormous lions cut in deep relief, and boldly standing on nothing, whilst they manage to hold up a diminutive coat of arms as a sort of finial to the arch. In the upper arcades griffins take the place of the lions, and the arches are again richly cusped. I noticed the date of A.D. 1570 on the capital of one of the columns, but this I have no doubt was the date of the Pagan alterations, and not that of the original fabric, which is said to have been erected in the year 1461. ”

“ Trinité [44] at Angers; in other words, by the adoption of intersecting arches planned on a square, the thrusts of all being received on the main piers, reinforced by an [45] intermediate transverse arch. And we note the appearance of the detached semi-arch beneath the roofing of the inferior aisles merging at its springing into the lateral arc-doubleau, and so resisting the thrust of the intersecting arches and transverse arches of the nave.
