Acanthus A genus of thistlelike plants whose leaves were imitated in the ornament of the Corinthian capital.
Adobe Sun-dried brick (Spanish). In American usage the word also de¬notes a house built of the material.
Aisle In a church, the enclosed space on either side of the nave.
Anta A square pier finishing off the end of a wall in Greek temple arch¬itecture. Columns are said to be “in antis” when they stand within a porch between antae.
Anthemion A Greek architectural ornament in the form of a stylized representation of the flower of the honey-suckle.
Arcaded corbel table A row of corbels linked by arches.
Architrave The lowest part of an entablature. It is sometimes used by itself, for example, as an enframement around a window.
Astylar Without columns or pilasters.
Baroque architecture An architecture that originated in Rome at the beginning of the seventeenth century and spread from there over Europe and to the European colonies in the New World. Classical (Roman) forms are used, as in Renaissance architecture; generally speaking, Baroque architecture is more freely modeled than Renaissance architecture and exploits effects of light and shade in ways that the latter does not. There are many national and regional varieties of Baroque, some of which have their own names (such as Churriguerresque). It made way for Neo-Classical architecture in the second half of the eighteenth century.
Basilican Of a church, having an oblong nave flanked by lower aisles, with clerestory windows in the nave walls above the aisle roofs.
Battered Of walls, having faces that slope inward toward the top. Belvedere A tower or turret built for the sake of the view.

Chicago window An oblong window with a wide central light contain¬ing a fixed pane of plate glass flanked by narrower lights with sashes. Churrigueresque A type of Baroque, characterized by very elaborate ornament, peculiar to Spain and Spanish America. Churriguerra was a Spanish architect who did not, as it happens, originate the style. But the term has been in use for a long time and is likely to continue in use un¬til somebody offers an unexceptionable alternative.
Classical architecture The architecture of Ancient Greece and Ancient Rome, and architecture using forms derived from Ancient Greek and Ancient Roman architecture.
Clerestory The nave wall pierced with windows above the aisle roofs of a church.
Colossal order An order with columns or pilasters that run up through more than one story of the building.

Dormer window An upright window lighting the space in a roof. When it is in the same plane as the wall, it is called a wall dormer, when it rises from the slope of the roof, a roof dormer.
Entablature The horizontal part of a classical order, above the columns or pilasters. It always has three parts, the lowest being called the archi¬trave, the middle one the frieze, and the top one the cornice; the design varies in detail according to the order being used.
Fanlight A semicircular or semielliptical window above a door. Flamboyant style The last style in French Gothic architecture, charac¬terized by flamelike curves in tracery and moldings.
Fleche ,4 small spire of wood and lead. (French: arrow.) Fluting Vertical grooving, as on a Greek column,

Greek fret A running ornament resembling a series of identical recti¬linear labyrinths or mazes.
Half timbering A technique of wooden-frame construction in which the members are exposed on the outside of the wall.

Neo-Grec A French architectural style of the mid-nineteenth century, characterized by planar wall effects and simplified Greek and Roman detail, with moldings of flattened profile and incised linear ornament.
Order The basic structural system of the Greek temple, consisting of columns with an entablature resting on them. The Greeks had three orders, the Doric, the Ionic, and the Corinthian; the Romans adopted the Greek orders, adding them to their own Tuscan; the Renaissance adopted the Roman orders and added the Composite. Each order had its own recognized proportions as well as its own set of ornamental features.

Piazza The term used for a veranda generally in the colonial period, and in the South to this day. In Italy a piazza is an open space in a town, a square. When Inigo Jones planned the great square in Covent Garden, London, in 1631, he called it Covent Garden Piazza, to show off his Italian. To his fellow Londoners the arcaded walks (loggie, as )ones might have called them) surrounding the square seemed the most novel thing in the design. So they assumed that they were what the architect must have been referring to, and piazza got its new, Anglo-American meaning.
Picturesque, the A philosophy of landscape design and architecture ac¬cording to which landscapes and buildings should exhibit qualities seen in, and should harmonize with each other as in, the pictures of the most admired landscape painters. It originated in England in the last quarter of the eighteenth century.

Renaissance architecture A style of architecture characterized by the use of forms derived from Ancient Roman architecture that began in Florence around 1=120, was taken up in other parts of Italy later in the fifteenth century, and in the rest of Western Europe in the sixteenth. The period 1420-1500 is called the Early Renaissance, 1500-1520 the High Renaissance, 1520-1600 the Late Renaissance or Mannerist Period. In many of the older histories of architecture (and some quite recent ones), all architecture from 1420 down to about 1750 is called “Renaissance.” However, the accepted term for the architecture of 1600-1750 is now Baroque.
Ribbed vault A vault with arches (ribs) where the surfaces meet at an angle.
Ridge The horizontal line of meeting of the upper slopes of a roof. Riser The vertical part of a step.

Steeple The main vertical feature of a church, comprising both the tower and the spire or other superstructure.
Stringcourse A projecting course (sometimes two or three courses) forming a narrow horizontal strip across the wall of a building.
Syrian arch A type of semicircular arch that has very low supports, with the result that the distance from the impost to the level of the crown of the arch is greater than the height of the impost from the ground. It is so called because it was used in the Early Christian churches of Syria, in the fifth and sixth centuries.
Tabernacle frame An enframement for a doorway or window consisting of two columns or pilasters with an entablature and pediment above.

Veranda A space alongside a house sheltered by a roof supported by posts, pillars, columns or arches. An earlier name for it in America was piazza. The French colonists called it a galerie, the Dutch a stoep (Americanized as stoop), the Spanish a portal; in Italy it is a loggia. The term porch is best retained (as in this book) for a shelter over a door. Veranda comes from the Portuguese varanda and was first used by the British in India.
Viga Beam (Spanish). Volute See Ionic order. Voussoir A wedge-shaped stone or brick in an arch.
Zoning regulations Legal restrictions which were intended in the first place to relieve street congestion by regulating the height of buildings. The New York Zoning Act of 1916, the first American act of the kind and the model for most later ones, determined the permissible height of walls next to the street by two factors, the type of district or zone and the width of the street. Additional stories above this had to be set back behind a line drawn from the center of the street through a point at the top of the front plane of the street wall, except that upon one quarter of the total lot area the building could rise to any height.
