See also:BUTTRESS (from the O. Fr. bouteret, that which bears a thrust, from bouter, to push, cf. Eng. " See also:butt " and " See also:abutment ")
, See also:masonry projecting from a See also:wall, provided to give additional strength to the same, and also to resist the thrust of the roof or wall, especially when concentrated at any one point
.
In See also:Roman See also:architecture the plans of the See also:building, where the vaults were of considerable span and the thrust therefore very See also:great, were so arranged as to provide See also:cross-walls, dividing the aisles, as in the See also:case of the See also:Basilica of See also:Maxentius, and, in the Thermae of See also:Rome, the subdivisions of the less important halls, so that there were no visible buttresses
.
In the See also:baths of See also:Diocletian, however, these cross-walls See also:rose to the height of the great vaulted See also:- HALL

In a See also:palace at Shuka in See also:Syria, attributed to the end of the 2nd See also:century A.U., where, in consequence of the See also:absence of See also:timber, it was necessary to See also:cover over the building with slabs of stones, these latter were carried on See also:arches thrown across the great hall, and this necessitated two precautions, viz. the See also:pro-See also:vision of an See also:abutment inside the building, and of buttresses outside, the earliest example in which the feature was frankly accepted
.
In See also:Byzantine See also:work there were no See also:external buttresses, the plans being arranged to include them in cross-walls or interior abutments
.
The buttresses of the See also:early Romanesque churches were only See also:pilaster strips employed to break up the wall See also:surface and decorate the exterior
.
At a slightly later See also:period a greater See also:depth was given to the See also:lower portion of the buttresses, which was then capped with a deep sloping weathering
.
The introduction of ribbed vaulting, extended to the See also:nave in the 12th century, and the concentration of thrusts on definite points of the structure, rendered the See also:buttress an See also:absolute See also:necessity, and from the first this would seem to have been recognized, and the architectural treatment already given to the Romanesque buttress received
a remarkable development
.
The buttresses of the early See also:English period have considerable See also:projection with two or three sets-off sloped at an acute See also:angle dividing the stages and crowned by triangular heads; and slender columns (" buttress shafts ") are used at the angle
.
In later work pinnacles and niches are usually employed to decorate the summits of the buttresses, and in the still later Perpendicular work the See also:vertical faces are all richly decorated with panelling
