Any attempt to show the development and interrelationship of styles is certain to incorporate generalizations and simplifications that do not express adequately the complexities of’ historical fact.. Nonetheless this chronology is presented in the hope that it. may dramatize the many options that have existed for American architects since the early seventeenth century.
The style entries for the seventeenth and eighteenth centuries describe ethnic and regional developments whereas those for the nineteenth and twentieth centuries are not geographical in organization since the rapid dispersal of’ architectural ideas increasingly erased regional distinctions. It should be remembered that virtually all building in the seventeenth century was vernacular in expression and relatively unselfconscious, while designers thereafter were increasingly selfconscious. The style entries of’ the nineteenth and twentieth centuries show those modes employed by architects, but they indicate little of the far larger volume of important vernacular building.
The dates at which a style emerges or later passes from use are often difficult to pinpoint, for Although it is sometimes known when the first of a type appeared, vernacular variations on a style or expression often continued in outlying areas well after its use had subsided in the area of origin, The dates shown here, therefore, should he considered approximate not absolute.

bracket A projecting support used tinder cornices, eaves, balconies, or windows to provide structural or purely visual support (see Fig. 107).
brickwork Three types of brickwork or bonding are common in eighteenth-century architecture. The simplest is common bond in which the bricks are all laid lengthwise to the plane of’ the wall. More complex is English bond in which the brick are laid in alternating courses, one course lengthwise (stretchers) and the other endwise (headers). Flemish bond is even more intricate with each course consisting of stretchers and headers (see illustration).

double hung window A window of two (or more) sash, or glazed frames, set in vertically grooved frames and capable of being raised or lowered independently of each other; widely in use in the American English colonies after c. 1700.
eave The lower edge, often overhanging, of a roof.
engaged column A column that is attached to and appears to emerge from the wall; in plan it consists of a half to three-quarters of a fully round column. It may he purely decorative or it may serve as a buttress-like thickening of the wall.
entablature The horizontal beam-like member supported by a classical column (see order). Although the details and proportions of the en¬tablatures of the Doric, Ionic, and Corinthian orders vary, each has three component parts: the lower architrave, the middle frieze, and the crowning cornice.
eyebrow dormer A dormer formed by bowing upward a section of the roof and inserting a narrow segmental window beneath (see Fig. 149).
fanlight A circular or elliptical window over a door, often with elaborately contrived and interwoven mullions; used extensively c. 1700 to c. 1820.

Flemish gable A masonry gable extended above the roof with setback stages that may have stepped or Curved profiles in any of a variety of combinations (see Pig. 2 1). Related to the crowstep gable.
foliate From Latin, foliatus, “bearing leaves.” Having a two-dimensional or carved three-dimensional pattern based on leaves or plants; often stylized.
frame A structural support composed of separate members joined together to form a cage, as contrasted to solid masonry construction. Traditionally a wooden frame was composed of large, hewn hardwood members fastened by complex interlocking joints (see mortise and tenon). The frame of the Gleason house is a good example. About 1830 a radically new method was introduced that employed mass-produced softwood lumber in a frame that could be much more speedily raised (sec Fig. 111 and the discussion of the balloon frame).
frieze From Latin use of the name Phrygia, a city known for its elaborate embroidery. Specifically the flat, horizontal panel in the entablature of the Ionic order, between the lower architrave and the crowning cornice ornamented with low relief sculpture (because of its resemblance to elaborate embroidery). Hence, by extension, the center panel or section of all entablatures, even in the much different Doric order which has grooved stylized beam ends (triglyphs). With the spaces between filled with panels of low relief sculpture (metopes); see order. By further ex¬tension any elevated horizontal decorative band or panel.
gable The triangularly shaped area enclosed by the two sloped surfaces of a gable roof and the wall below; a generic term distinct from pediment which refers to a portion of a classical facade.

In the colonies used by Dutch, Swedish, and English settlers, though in each area the profile differed. For a typically Dutch or Walloon gambrel roof, see Fig. 17; for an example derived from Swedish influences, see Fig. 28.
golden section A proportional ratio devised by the Greeks that expresses the ideal relationship of unequal parts. Capable of being demonstrated by Euclidian geometry, it can also be stated thus: a is to b as b is to a + b, or a/b= b/a+b. If this is rewritten as a quadratic equation, the value 1 assigned to a, and solved for b, the value of b is 1.618034. Thus, the golden section is 1:1.618.
half timbering Frame construction in wood in which the framing members are left exposed on both exterior and interior, with the spaces between the framing members filled with brick nogging (ran-dom brickwork) or wattle and daub. Practiced in medieval France and England and briefly in the English colonies, it was revived as a purely decorative motif early in the twentieth century by using applied “hall timbering,” which is not structural.
hipped roof A roof of four sloped surfaces that meet in a point (with a square plan) or a sharp ridge line (rectangular plan) (see Figs. 132, 175).
hood molding A large projected molding over a window used to throw rain water away from the window; sometimes supported by brackets.
in antis Used to described columns set between projecting walls (antae).
Ionic order See order.
lancet Used to describe extremely narrow sharply pointed Gothic win¬dows (hence the name) (see Fig. 91).
lantern In architecture, a small square or round glazed structure built atop a larger structure to admit light (see Figs. 60, 83).

loggia Italian, from French, loge, “small house, hut.” A covered but open gallery, often in the upper part of a building; also, a covered pas¬sageway, often with an open trellis roof, connecting two buildings.
Mansard roof From Francois Mansart, French architect, 1598-1666, who employed this roof form extensively. A roof with two Slopes on each of its four sides – a steep and nearly vertical slope on the outside and a gentle nearly flat slope on the top (see Figs. 115, 118). The outer roof slope may often be convex or concave in profile.
modillion From French and Italian, modiglione; from Latin, mutulus, from an Etruscan root meaning “to stand out.” A small curved and or¬namented bracket used to support the upper part of the cornice in the Corinthian order; any such small curved ornamented bracket used in series.

monitor A form of lantern, but wider and usually square in plan.
mortise and tenon One of the basic wood joining methods. One member is cut with a rectangular or square hole (mortise) to receive the other member cut with a rectangular or square tongue (tenon).
mouse tooth gable (muisetanden gable) Dutch term referring to the infilling in the steps of a crowstep gable. Brick is laid at an angle perpendicular to the slope of the gable within the steps, and the gable is finished off with a smooth brick or stone coping or sill; an adaptation widely used in New Netherlands and Virginia.

order From OId French ordre; from Latin, ordo, “line or row;” possibly from Greek, arariskein, “to fit together.” Any of the several types of classical columns, including pedestal bases and entablatures. The Greeks developed three orders, the Doric, Ionic, and Corinthian, of which the Romans adopted the latter two and added Tuscan Doric and the Composite (a combination of the features of Ionic and Corinthian). 1. The Greek Doric, developed in the western Dorian region of Greece, is the heaviest and most massive of the orders. It rises from the stylobate without any base; it is from 4 to 6 1/2 times as tall as its diameter; it has twenty broad flutes. The capital consists simply of a banded necking swelling out into a smooth echinus which carries a flat square abacus. The Doric entablature is also the heaviest, being about one fourth the height of the column. The Greek Doric order was not used after c. 100 B.C. until its “rediscovery” in the mid-eighteenth-century. 2. The Ionic order was developed along the west coast of what is now Turkey, once Ionian Greece. It is generally about nine times as high as its diameter. It has a base, twenty-four flutes, and a much more elaborate capital consisting of a decorative band and a circular egg and dart molding on which rests the distinctive volute; on top of the volute rests a thin flat abacus. The Ionic entablature is about one-fifth the height of the column. 3. The Corinthian order, the most attenuated and richly embellished, was the least used by the Greeks. It is about ten times as high as its diameter, rising from a base, with twenty-four flutes, and a tall capital consisting of a band from which spread upward three or four layers of curling acanthus leaves ending in tight volutes in the four corners and supporting a concave abacus. The Corinthian entablature is also about one-fifth the height of the column. 4. Other orders: The Roman Doric order is much slimmer than the Greek prototype, being nearly as slender as the Ionic order: moreover it has a short base. More original is the Tuscan Doric order which has a base and an unfluted shaft and is about seven times as high as its diameter; its capital is similar to that of the Greek original but more strongly articulated. The Romans also combined the Ionic and Corinthian or¬ders, placing the volutes atop the acanthus leaves, creating the Com¬posite order, the most sculpturally elaborate of them all.
Palladian window A type of opening or window much used by Sebastiano Serlio and Andrea Palladio (hence the name) with a tall round-headed miter opening flanked by shorter rectangular openings. Four columns or pilasters frame the flanking openings and the entablatures they carry form a base for the arch framing the center opening (see the window of the Ely house, Ely’s Landing, Connecticut, and Figs. 29, 42).
pavilion From Old English, pavilon; from Latin, papilio, “butterfly,” per¬haps because of the resemblance of ornamental tents to butterfly wings. Originally a tent, especially an elaborately ornamented shelter; later, any portion of a building projected forward and otherwise set apart, or even a separate structure. Much favored in French Renaissance and especially Baroque architecture, and hence in Second Empire Baroque architecture, 1850-1890 (see Figs. 122, 116, 118).
pediment From variation of obsolete English, perement, perhaps from pyramid. Originally the triangular gable above the entablature of Greek and Roman temples enclosed by the horizontal cornice of the entablature, and raking cornices following the edges of the roof (sec Fig. 81); later, any such cornice-framed crown over a door or window, whether triangular (Fig. 29) or segmental (Fig. 40), or broken (Fig. 31), or consisting of curved broken cornices ending in volutes (fig. 26).

pilaster From Old French, pilastre; from Medieval Latin, pilastrum, “pil¬lar.” A buttress-like projection from a wall in the form of one of the classical orders, and like them, having base, fluted or unfluted shaft, and capital, carrying an entablature or cornice.
plinth From French, plinthe; from Greek, plinthos, “square stone block.” Specifically, a square flat block Used as the base under a column, but by extension any block-like podium beneath a building.
polychromy From Greek polukhromos, from polus, “many,” + khroma, “color.” The use of many colors, and particularly in nineteenth century architecture the employment of many building materials with contrasting natural colors (see Fig. 122).
porte cochere From French, “coach door.” A covered area, attached to a house, providing shelter for those alighting from carriages (see Figs. 176, 177).

quatrefoil From Latin, “four leaves.” An ornamental pattern of four circular or pointed lobes.
quoin From Old French, coing, “wedge.” Originally the structural use of large masonry blocks to reinforce the corner of a brick or other masonry wall (see Fig. 45); but often used as a decorative embellishment in non-load-bearing materials (see applied wooden quoins, Fig. 26).
rinceau From Middle French, rainsel, “branch.” Ornamental work, often low relief sculpture, consisting of curvilinear intertwining leaves and branches.
rosette Stylized circular floral ornament in the form of a fully open rose.
rustication From Latin, rusticus, “of the country, rude, coarse.” The treatment of stone masonry with the joints between the blocks deeply cut back. The surfaces of the blocks may be smoothly dressed (as in Fig. 168), textured (us in Fig. 122), or extremely rough, or quarry-faced (as in Fig. 151b).
saddleback roof Traditionally a roof with two gables and one ridge, but also a roof (gable or hipped) with two slopes on each side, the outer portion gentler in slope, the inner portion steeper (see Fig. 46).
saltbox Term used to describe the typical seventeenth-century New England house with a short gable roof to the front and a long gable roof to the rear (see Fig. 13).
sash From French, chassis, “frame.” Frame in which glass window panes are set.
setback A recessed upper section of a building; used in New York and Chicago skyscrapers of the 1920s as a way of admitting more light and air to the streets below (see Figs. 207, 209).
