Anorder inarchitecture is a certain assemblage of parts subject to uniform established proportions, regulated by the office that each part has to perform.[1]Coming down to the present fromAncient Greek andAncient Roman civilization, thearchitectural orders are the styles ofclassical architecture, each distinguished by its proportions and characteristic profiles and details, and most readily recognizable by the type ofcolumn employed. The three orders of architecture—theDoric,Ionic, andCorinthian—originated in Greece. To these the Romans added, in practice if not in name, theTuscan, which they made simpler than Doric, and theComposite, which was more ornamental than the Corinthian. The architectural order of a classical building is akin to themode orkey ofclassical music; thegrammar orrhetoric of a written composition. It is established by certainmodules like theintervals of music, and it raises certain expectations in an audience attuned to its language.[2]
Whereas the orders were essentially structural inAncient Greek architecture, which made little use of the arch until its late period, inRoman architecture where the arch was often dominant, the orders became increasingly decorative elements except inporticos and similar uses. Columns shrank into half-columns emerging from walls or turned intopilasters. This treatment continued after the conscious and "correct" use of the orders, initially following exclusively Roman models, returned in theItalian Renaissance.[3]Greek Revival architecture, inspired by increasing knowledge of Greek originals, returned to more authentic models, including ones from relatively early periods.

Each style has distinctivecapitals at the top of columns and horizontalentablatures which it supports, while the rest of the building does not in itself vary between the orders. The column shaft and base also varies with the order, and is sometimes articulated with vertical concave grooves known asfluting. The shaft is wider at the bottom than at the top, because itsentasis, beginning a third of the way up, imperceptibly makes the column slightly more slender at the top, although some Doric columns, especially early Greek ones, are visibly "flared", with straight profiles that narrow going up the shaft.
The capital rests on the shaft. It has a load-bearing function, which concentrates the weight of the entablature on the supportive column, but it primarily serves an aesthetic purpose. The necking is the continuation of the shaft, but is visually separated by one or many grooves. Theechinus lies atop the necking. It is a circular block that bulges outwards towards the top to support theabacus, which is a square or shaped block that in turn supports the entablature. The entablature consists of three horizontal layers, all of which are visually separated from each other using moldings or bands. In Roman and post-Renaissance work, the entablature may be carried from column to column in the form of anarch that springs from the column that bears its weight, retaining its divisions and sculptural enrichment, if any. There are names for all the many parts of the orders.
The heights of columns are calculated in terms of a ratio between the diameter of the shaft at its base and the height of the column. A Doric column can be described as seven diameters high, an Ionic column as eight diameters high, and a Corinthian column nine diameters high, although the actual ratios used vary considerably in both ancient and revived examples, but still keeping to the trend of increasing slimness between the orders. Sometimes this is phrased as "lower diameters high", to establish which part of the shaft has been measured.
There are three distinct orders in Ancient Greek architecture: Doric, Ionic, and Corinthian. These three were adopted by the Romans, who modified their capitals. The Roman adoption of the Greek orders took place in the 1st century BC. The three ancient Greek orders have since been consistently used in EuropeanNeoclassical architecture.
Sometimes the Doric order is considered the earliest order, but there is no evidence to support this. Rather, the Doric and Ionic orders seem to have appeared at around the same time, the Ionic in eastern Greece and the Doric in the west and mainland.
Both the Doric and the Ionic order appear to have originated in wood. TheTemple of Hera in Olympia is the oldest well-preserved temple of Doric architecture. It was built just after 600 BC. The Doric order later spread across Greece and intoSicily, where it was the chief order for monumental architecture for 800 years. Early Greeks were no doubt aware of the use of stone columns with bases and capitals inancient Egyptian architecture, and that of other Near Eastern cultures, although there they were mostly used in interiors, rather than as a dominant feature of all or part of exteriors, in the Greek style.
The Doric order originated on the mainland and westernGreece. It is the simplest of the orders, characterized by short, organized, heavy columns with plain, roundcapitals (tops) and no base. With a height that is only four to eight times its diameter, the columns are the most squat of all orders. The shaft of the Doric order is channeled with 20 flutes. The capital consists of a necking orannulet, which is a simple ring. The echinus is convex, or circular cushion like stone, and theabacus is a square slab of stone.
Above the capital is a square abacus connecting the capital to the entablature. The entablature is divided into three horizontal registers, the lower part of which is either smooth or divided by horizontal lines. The upper half is distinctive for the Doric order. The frieze of the Doric entablature is divided intotriglyphs andmetopes. A triglyph is a unit consisting of three vertical bands which are separated by grooves. Metopes are the plain or carved reliefs between two triglyphs.
The Greek forms of the Doric order come without an individual base. They instead are placed directly on thestylobate. Later forms, however, came with the conventional base consisting of a plinth and a torus. The Roman versions of the Doric order have smaller proportions. As a result, they appear lighter than the Greek orders.
The Ionic order came from eastern Greece, where its origins are entwined with the similar but little knownAeolic order. It is distinguished by slender, flutedpillars with a large base and two opposedvolutes (also called "scrolls") in the echinus of the capital. The echinus itself is decorated with anegg-and-dartmotif. The Ionic shaft comes with four more flutes than the Doric counterpart (totalling 24). The Ionic base has two convex moldings calledtori, which are separated by a scotia.
The Ionic order is also marked by anentasis, a curved tapering in the column shaft. A column of the Ionic order is nine times more tall than its lower diameter. The shaft itself is eight diameters high. The architrave of the entablature commonly consists of three stepped bands (fasciae). The frieze comes without the Doric triglyph and metope. The frieze sometimes comes with a continuous ornament such as carved figures instead.

The Corinthian order is the most elaborated of the Greek orders, characterized by a slender fluted column having an ornate capital decorated with two rows ofacanthus leaves and four scrolls. The shaft of the Corinthian order has 24 flutes. The column is commonly ten diameters high.
The Roman writerVitruviuscredited the invention of the Corinthian order toCallimachus, a Greeksculptor of the 5th century BC. The oldest known building built according to this order is theChoragic Monument of Lysicrates in Athens, constructed from 335 to 334 BC. The Corinthian order was raised to rank by the writings of Vitruvius in the 1st century BC.

The Romans adapted all the Greek orders and also developed two orders of their own, basically modifications of Greek orders. However, it was not until theRenaissance that these were named and formalized as theTuscan andComposite, respectively the plainest and most ornate of the orders. The Romans also invented theSuperposed order. A superposed order is when successive stories of a building have different orders. The heaviest orders were at the bottom, whilst the lightest came at the top. This means that the Doric order was the order of the ground floor, the Ionic order was used for the middle story, while the Corinthian or the Composite order was used for the top story.
The Tuscan order has a very plain design, with a plain shaft, and a simple capital, base, and frieze. It is a simplified adaptation of the Greeks' Doric order. The Tuscan order is characterized by an unfluted shaft and a capital that consists of only an echinus and an abacus. In proportions it is similar to the Doric order, but overall it is significantly plainer. The column is normally seven diameters high. Compared to the other orders, the Tuscan order looks the most solid.

The Composite order is a mixed order, combining the volutes of the Ionic with the leaves of the Corinthian order. Until the Renaissance it was not ranked as a separate order. Instead it was considered as a late Roman form of the Corinthian order. The column of the Composite order is typically ten diameters high.
TheRenaissance period saw renewed interest in the literary sources of the ancient cultures of Greece and Rome, and the fertile development of a new architecture based on classical principles. The treatiseDe architectura by Roman theoretician, architect and engineerVitruvius, is the only architectural writing that survived from Antiquity. Effectively rediscovered in the 15th century,Vitruvius came to be regarded as the ultimate authority on architecture. However, in his text the wordorder is not to be found. To describe the four species of columns (he only mentions: Tuscan, Doric, Ionic and Corinthian) he uses, in fact, various words such as:genus (gender),mos (habit, fashion, manner),opera (work).
TheSt-Gervais-et-St-Protais Church in Paris presents columns of the three orders: Doric at the ground floor, Ionic at the second floor, Corinthian at the third floor.
The termorder, as well as the idea of redefining thecanon started circulating in Rome, at the beginning of the 16th century, probably during the studies of Vitruvius' text conducted and shared byPeruzzi,Raphael, and Sangallo.[4]Ever since, the definition of thecanon has been a collective endeavor that involved several generations of European architects, from Renaissance and Baroque periods, basing their theories both on the study of Vitruvius' writings and the observation of Roman ruins (the Greek ruins became available only after Greek Independence, 1821–1823). What was added were rules for the use of the Architectural Orders, and the exact proportions of them in minute detail. Commentary on the appropriateness of the orders for temples devoted to particular deities (Vitruvius I.2.5) were elaborated by Renaissance theorists, with Doric characterized as bold and manly, Ionic as matronly, and Corinthian as maidenly.[5]
Following the examples of Vitruvius and the five books of theRegole generali di architettura sopra le cinque maniere de gli edifici bySebastiano Serlio published from 1537 onwards,Giacomo Barozzi da Vignola produced an architecture rule book that was not only more practical than the previous two treatises, but also was systematically and consistently adopting, for the first time, the term 'order' to define each of the five different species of columns inherited from antiquity. A first publication of the various plates, as separate sheets, appeared in Rome in 1562, with the title:Regola delli cinque ordini d'architettura ("Canon of the Five Orders of Architecture").[6] As David Watkin has pointed out, Vignola's book "was to have an astonishing publishing history of over 500 editions in 400 years in ten languages, Italian, Dutch, English, Flemish, French, German, Portuguese, Russian, Spanish, Swedish, during which it became perhaps the most influential book of all times".[7]
The book consisted simply of an introduction followed by 32 annotated plates, highlighting the proportional system with all the minute details of the Five Architectural Orders. According to Christof Thoenes, the main expert of Renaissance architectural treatises, "in accordance with Vitruvius's example, Vignola chose a "module" equal to a half-diameter which is the base of the system. All the other measurements are expressed in fractions or in multiples of this module. The result is an arithmetical model, and with its help each order, harmoniously proportioned, can easily be adapted to any given height, of a façade or an interior. From this point of view, Vignola's Regola is a remarkable intellectual achievement".[8]
In America,The American Builder's Companion,[9] written in the early 19th century by the architectAsher Benjamin, influenced many builders in the eastern states, particularly those who developed what became known as theFederal style. The last American re-interpretation of Vignola'sRegola, was edited in 1904 by William Robert Ware.[10]
The break from the classical mode came first with theGothic Revival architecture, then the development of modernism during the 19th century. TheBauhaus promoted pure functionalism, stripped of ornament considered superfluous, and that has become one of the defining characteristics ofmodern architecture. There are some exceptions.Postmodernism introduced an ironic use of the orders as a cultural reference, divorced from the strict rules of composition. On the other hand, a number of practitioners such asQuinlan Terry in England, andMichael Dwyer,Richard Sammons, andDuncan Stroik in the United States, continue the classical tradition, and use the classical orders in their work.
Several orders, usually based upon the composite order and only varying in the design of the capitals, have been invented under the inspiration of specific occasions, but have not been used again. They are termed "nonce orders" by analogy tononce words; several examples follow below.
These nonce orders all express the "speaking architecture" (architecture parlante) that was taught in the Paris courses, most explicitly byÉtienne-Louis Boullée, in which sculptural details of classical architecture could be enlisted to speak symbolically, the better to express the purpose of the structure and enrich its visual meaning with specific appropriateness. This idea was taken up strongly in the training ofBeaux-Arts architecture,c. 1875–1915.[citation needed]
Robert Adam's brotherJames was in Rome in 1762, drawing antiquities under the direction ofClérisseau; he invented a "British order" and published an engraving of it. Its capital the heraldic lion and unicorn take the place of the Composite's volutes, a Byzantine or Romanesque conception, but expressed in terms of neoclassical realism. Adam's ink-and-wash rendering with red highlighting is at theAvery Library,Columbia University.
Sir Edwin Lutyens, who from 1912 laid outNew Delhi as the new seat of government for theBritish Empire in India,[15] designed a Delhi order having a capital displaying a band of vertical ridges, and with bells hanging at each corner as a replacement for volutes.[16] His design for the new city's central palace, Viceroy's House, now the Presidential residenceRashtrapati Bhavan, New Delhi, was a thorough integration of elements ofIndian architecture into a building of classical forms and proportions,[17] and made use of the order throughout.[16] The Delhi Order reappears in some later Lutyens buildings includingCampion Hall, Oxford.[18]
In the United StatesBenjamin Latrobe, the architect of theCapitol building in Washington, DC, designed a series of botanical American orders. Most famous is the Corinthian order substituting ears of corn and their husks for the acanthus leaves, which was executed by Giuseppe Franzoni and used in the small domed vestibule of the Senate. Only this vestibule survived theBurning of Washington in 1814, nearly intact.[19]
With peace restored, Latrobe designed an American order that substituted tobacco leaves for the acanthus, of which he sent a sketch toThomas Jefferson in a letter, 5 November 1816. He was encouraged to send a model of it, which remains atMonticello. In the 1830sAlexander Jackson Davis admired it enough to make a drawing of it. In 1809 Latrobe invented a second American order, employingmagnolia flowers constrained within the profile of classical mouldings, as his drawing demonstrates. It was intended for "the Upper Columns in the Gallery of the Entrance of the Chamber of the Senate".[20]
