Glossary

Aisle

Subsidiary space alongside the body of a building, separated from it by columns, piers or posts. Also (especially Scots) projecting wing of a church, often for special use, e.g. by a guild or by a landed family whose burial place it may contain.

Arch

Types include: Basket arch or Anse de Panier (French, lit. basket handle): three-centred and depressed, or with a flat centre. Chancel: dividing chancel from nave or crossing in a church. Crossing: spanning piers at a crossing in a church. Depressed or three-centred: with a rounded top, but curving inward more at the sides. Four-centred: with four arcs, the lower two curving inward more than the upper, with a blunt central point; typical of late medieval English architecture. Jack arch: shallow segmental vault springing from beams, used for fireproof floors, bridge decks, etc. Ogee (adjective ogival): a pointed arch with a double reverse curve, especially popular in the 14th century; a nodding ogee curves forward from the wall face at the top. Parabolic: shaped like a chain suspended from two level points, but inverted. Relieving or discharging: incorporated in a wall to relieve superimposed weight. Shouldered: with arcs in each corner and a flat centre or lintel. Skew: spanning responds not diametrically opposed. Stilted: with a vertical section above the impost i.e. the horizontal moulding at the springing. Strainer: inserted in an opening to resist inward pressure. Three-centred: see Depressed, above. Transverse: spanning a main axis (e.g. of a vaulted space). Triumphal arch: influential type of Imperial Roman monument, free-standing, with a square attic or top section and broad sections to either side of the main opening, often with lesser openings or columns. Tudor: with arcs in each corner joining straight lines to the central point. Two-centred: the simplest kind of pointed arch.

Baroque

The term, originally derogatory, for a style at its peak in 17th- and early 18th-century Europe, which developed the classical architecture of the Renaissance towards greater extravagance and drama. Its innovations included greater freedom from the conventions of the orders, much interplay of concave and convex forms, and a preference for the single visual sweep. The revival of the style in early 20th-century Britain, often termed Edwardian Baroque or Neo-Baroque, drew more on English prototypes than on the more expansive variants of the Continent.

Base

Moulded foot of a column or pilaster. An Attic base is the form used on an Ionic column, with two large convex rings joined by a spreading convex moulding.

Bay

Division of an elevation or interior space as defined by regular vertical features such as arches, columns, windows etc.

Blocked

Interrupted by regular projecting blocks (blocking), as on a Gibbs surround.

Capital

Head or crowning feature of a column or pilaster.

Chancel

The eastern part or end of a church, where the altar is placed; usually set apart for the clergy.

Choir

The part of a cathedral, monastic church or collegiate church where services are sung.

Cornice

Flat-topped ledge with moulded underside, projecting along the top of a building or feature, especially as the highest member of the classical entablature. Also the decorative moulding in the angle between wall and ceiling. An eaves cornice overhangs the edge of a roof.

Crown

The upper part of an arch or vault.

Font

Vessel in a church or chapel for baptismal water, usually of stone or lead.

Gallery

A long room or passage; an upper storey above the aisles of a church, looking through arches to the nave; a balcony or mezzanine overlooking the main interior space of a building; or an external walkway.

Ionic

One of the orders of classical architecture, distinguished in particular by downward- and inward-curling spirals (called volutes) on the capital of the column.

Moulding

Shaped ornamental strip of continuous section, e.g. the classical cavetto, cyma or ovolo.

Nave

The body of a church west of the crossing or chancel, often flanked by aisles.

Panelling

Wooden lining to interior walls, made up of vertical members (muntins) and horizontals (rails) framing panels; also called wainscot. Raised and fielded: with the central area of the panel (field) raised up. Also used for stonework treated with sunk or raised panels.

Pediment

A formalized gable derived from that of a classical temple; also used over doors, windows etc. A broken pediment has its apex omitted. An open pediment has the centre of the base omitted. A broken pediment with double-curved sides is called a swan-neck pediment.

Pier

Large masonry or brick support, often for an arch. A compound pier is composed of grouped shafts, or a solid core surrounded by shafts.

Predella

In an altarpiece, the horizontal strip below the main representation, often used for subsidiary representations.

Quoins

Dressed or otherwise emphasized stones at the angles of a building, or their imitation in brick or other materials.

Roman

The architecture of the Roman Empire, to which most of Britain belonged from 43 to c. 410 A.D. Our knowledge of Romano-British architecture depends mostly on archaeological reconstructions from foundations and fragments, though some notable fortifications and other military works survive above ground level in recognizable form.

Round

(Scots): A rounded bartizan or turret, usually roofless. An angle round is set at a corner.

Spire

Tall pyramidal or conical feature crowning a tower or turret. Broach: starting from a square base, then carried into an octagonal section by means of triangular faces. Splayed-foot: variation of the broach form, found in England principally in the south-east, in which the four cardinal faces are splayed out near their bases, to cover the corners, while oblique (or intermediate) faces taper away to a point. Needle spire: thin spire rising from the centre of a tower roof, well inside the parapet.

Touch

Soft black marble quarried near Tournai in Belgium.

Tunnel vault

The simplest kind of vault, in the form of a continuous semicircular or pointed arch; also called a barrel vault.
