A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. The term column applies especially to a large round support with a capital and a base or pedestal, which is made of stone, or appearing to be so. A small wooden or metal support is typically called a post. Supports with a rectangular or other non-round section are usually called piers.
An order in architecture is a certain assemblage of parts subject to uniform established proportions, regulated by the office that each part has to perform. Coming down to the present from Ancient Greek and Ancient Roman civilization, the architectural orders are the styles of classical architecture, each distinguished by its proportions and characteristic profiles and details, and most readily recognizable by the type of column employed. The three orders of architecture—the Doric, Ionic, and Corinthian—originated in Greece. To these the Romans added, in practice if not in name, the Tuscan, which they made simpler than Doric, and the Composite, which was more ornamental than the Corinthian. The architectural order of a classical building is akin to the mode or key of classical music; the grammar or rhetoric of a written composition. It is established by certain modules like the intervals of music, and it raises certain expectations in an audience attuned to its language.
The Corinthian order is the last developed and most ornate of the three principal classical orders of Ancient Greek architecture and Roman architecture. The other two are the Doric order, which was the earliest, followed by the Ionic order. In Ancient Greek architecture, the Corinthian order follows the Ionic in almost all respects, other than the capitals of the columns, though this changed in Roman architecture.
Ancient Greek architecture came from the Greeks, or Hellenics, whose culture flourished on the Greek mainland, the Peloponnese, the Aegean Islands, and in colonies in Anatolia and Italy for a period from about 900 BC until the 1st century AD, with the earliest remaining architectural works dating from around 600 BC.
The Doric order was one of the three orders of ancient Greek and later Roman architecture; the other two canonical orders were the Ionic and the Corinthian. The Doric is most easily recognized by the simple circular capitals at the top of the columns. Originating in the western Doric region of Greece, it is the earliest and, in its essence, the simplest of the orders, though still with complex details in the entablature above.
The Ionic order is one of the three canonic orders of classical architecture, the other two being the Doric and the Corinthian. There are two lesser orders: the Tuscan, and the rich variant of Corinthian called the composite order. Of the three classical canonic orders, the Corinthian order has the narrowest columns, followed by the Ionic order, with the Doric order having the widest columns.
In architecture the capital or chapiter forms the topmost member of a column. It mediates between the column and the load thrusting down upon it, broadening the area of the column's supporting surface. The capital, projecting on each side as it rises to support the abacus, joins the usually square abacus and the usually circular shaft of the column. The capital may be convex, as in the Doric order; concave, as in the inverted bell of the Corinthian order; or scrolling out, as in the Ionic order. These form the three principal types on which all capitals in the classical tradition are based. The Composite order established in the 16th century on a hint from the Arch of Titus, adds Ionic volutes to Corinthian acanthus leaves.
In classical architecture, a giant order, also known as colossal order, is an order whose columns or pilasters span two storeys. At the same time, smaller orders may feature in arcades or window and door framings within the storeys that are embraced by the giant order.
An entablature is the superstructure of moldings and bands which lies horizontally above columns, resting on their capitals. Entablatures are major elements of classical architecture, and are commonly divided into the architrave, the frieze, and the cornice. The Greek and Roman temples are believed to be based on wooden structures, the design transition from wooden to stone structures being called petrification.
Greek temples were structures built to house deity statues within Greek sanctuaries in ancient Greek religion. The temple interiors did not serve as meeting places, since the sacrifices and rituals dedicated to the respective ouranic deity took place outside them, within the wider precinct of the sanctuary, which might be large. Temples were frequently used to store votive offerings. They are the most important and most widespread surviving building type in Greek architecture. In the Hellenistic kingdoms of Southwest Asia and of North Africa, buildings erected to fulfill the functions of a temple often continued to follow the local traditions. Even where a Greek influence is visible, such structures are not normally considered as Greek temples. This applies, for example, to the Graeco-Parthian and Bactrian temples, or to the Ptolemaic examples, which follow Egyptian tradition. Most Greek temples were oriented astronomically.
The Tuscan order is one of the two classical orders developed by the Etruscans, the other being the composite order. It is influenced by the Doric order, but with un-fluted columns and a simpler entablature with no triglyphs or guttae. While relatively simple columns with round capitals had been part of the vernacular architecture of Italy and much of Europe since at least Etruscan architecture, the Romans did not consider this style to be a distinct architectural order. Its classification as a separate formal order is first mentioned in Isidore of Seville's Etymologies and refined during the Italian Renaissance.
A gutta is a small water-repelling, cone-shaped projection used near the top of the architrave of the Doric order in classical architecture. At the top of the architrave blocks, a row of six guttae below the narrow projection of the taenia (fillet) formed an element called a regula. A regula was aligned under each triglyph of the Doric frieze. In addition, the underside of the projecting geison above the frieze had rectangular protrusions termed mutules that each had three rows of six guttae. These mutules were aligned above each triglyph and each metope.
The Composite order is a mixed order, combining the volutes of the Ionic order capital with the acanthus leaves of the Corinthian order. In many versions the composite order volutes are larger, however, and there is generally some ornament placed centrally between the volutes. The column of the composite order is typically ten diameters high, though as with all the orders these details may be adjusted by the architect for particular buildings. The Composite order is essentially treated as Corinthian except for the capital, with no consistent differences to that above or below the capital.

San Sebastiano is an Early Renaissance church in Mantua, northern Italy. Begun in 1460 according to the designs of Leon Battista Alberti, it was left partially completed in the mid-1470s, by which time construction had slowed and was no longer being directed by Alberti. As a consequence, little remains of Alberti’s work apart from the plan, which is considered one of the earliest and most significant examples of Renassiances centrally-planned churches. The plan is in the shape of a Greek cross, with three identical arms centering apses, under a central cross-vaulted space without any interior partitions. The church sits on a ground-level crypt which was intended to serve as a mausoleum for the Gonzaga family.
Fluting in architecture and the decorative arts consists of shallow grooves running along a surface. The term typically refers to the curved grooves (flutes) running vertically on a column shaft or a pilaster, but is not restricted to those two applications. If the hollowing out of material meets in a point, the point is called an arris. If the raised ridge between two flutes appears flat, the ridge is a fillet.
The David W. Dyer Federal Building and U.S. Courthouse, formerly known simply as the U.S. Post Office and Courthouse, is an historic United States Post Office and federal courthouse of the United States District Court for the Southern District of Florida located at 300 Northeast 1st Avenue in Miami, Florida. Built in 1931 of limestone, it is the largest such structure in South Florida.
The Carl Albert Federal Building is a historic courthouse located in McAlester, Oklahoma. Built in 1914, the facility was renamed in 1985 in honor of former Speaker of the House Carl Albert, a native of the town. It previously served the United States District Court for the Eastern District of Oklahoma. It was listed on the National Register of Historic Places in 2000.
An anta capital is the crowning portion of an anta, the front edge of a supporting wall in Greek temple architecture. The anta is generally crowned by a stone block designed to spread the load from the superstructure (entablature) it supports, called an "anta capital" when it is structural, or sometimes "pilaster capital" if it is only decorative as often during the Roman period.
In the 16th century, the Renaissance, which called for a return to the models of Roman antiquity, spread throughout Europe from Italy, notably through treatises and engravings referring to the treatise De architectura by Vitruvius, Roman theorist of ancient architecture. Each center of culture and creation reinterpreted these new references according to its local traditions.
