In architecture, an impost or impost block is a projecting block resting on top of a column or embedded in a wall, serving as the base for the springer or lowest voussoir of an arch. [1] [2]
In architecture, an impost or impost block is a projecting block resting on top of a column or embedded in a wall, serving as the base for the springer or lowest voussoir of an arch. [1] [2]
The imposts are left smooth or profiled, and "then express a certain separation between abutment and arch." [3] The Byzantine fighters are high blocks, which are sometimes referred to as pulvino. The Romanesque designed the impost ornamentally or figuratively, similar to the capitals. In the Gothic period, the fighter almost completely disappeared from the calyx bud capital. The architecture of the Renaissance returns to the formation of the imposts of the ancient column orders. [4]
Sometimes the complete entablature of a smaller order is employed, as in the case of the Venetian or Palladian window, where the central opening has an arch resting on the entablature of the pilasters which flank the smaller window on each side. In Romanesque and Gothic work the capitals with their abaci take the place of the impost mouldings. [5]
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.
Romanesque architecture is an architectural style of medieval Europe characterized by semi-circular arches. There is no consensus for the beginning date of the Romanesque style, with proposals ranging from the 6th to the 11th century, this later date being the most commonly held. In the 12th century it developed into the Gothic style, marked by pointed arches. Examples of Romanesque architecture can be found across the continent, making it the first pan-European architectural style since Imperial Roman architecture. The Romanesque style in England and Sicily is traditionally referred to as Norman architecture.
Gothic architecture is an architectural style that was prevalent in Europe from the late 12th to the 16th century, during the High and Late Middle Ages, surviving into the 17th and 18th centuries in some areas. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. It originated in the Île-de-France and Picardy regions of northern France. The style at the time was sometimes known as opus Francigenum ; the term Gothic was first applied contemptuously during the later Renaissance, by those ambitious to revive the architecture of classical antiquity.
Aachen Cathedral is a Roman Catholic church in Aachen, Germany and the seat of the Roman Catholic Diocese of Aachen.
In architecture, a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket. A corbel is a solid piece of material in the wall, whereas a console is a piece applied to the structure. A piece of timber projecting in the same way was called a "tassel" or a "bragger" in England.
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 architecture, an abacus is a flat slab forming the uppermost member or division of the capital of a column, above the bell. Its chief function is to provide a large supporting surface, tending to be wider than the capital, as an abutment to receive the weight of the arch or the architrave above. The diminutive of abacus, abaculus, is used to describe small mosaic tiles, also called abaciscus or tessera, used to create ornamental floors with detailed patterns of chequers or squares in a tessellated pavement.
A rib vault or ribbed vault is an architectural feature for covering a wide space, such as a church nave, composed of a framework of crossed or diagonal arched ribs. Variations were used in Roman architecture, Byzantine architecture, Islamic architecture, Romanesque architecture, and especially Gothic architecture. Thin stone panels fill the space between the ribs. This greatly reduced the weight and thus the outward thrust of the vault. The ribs transmit the load downward and outward to specific points, usually rows of columns or piers. This feature allowed architects of Gothic cathedrals to make higher and thinner walls and much larger windows.
An anta, or sometimes parastas, is an architectural term describing the posts or pillars on either side of a doorway or entrance of a Greek temple – the slightly projecting piers which terminate the walls of the naos. It differs from the pilaster, which is purely decorative, and does not have the structural support function of the anta.

The Church of Saint-Germain-des-Prés is a Roman Catholic parish church located in the Saint-Germain-des-Prés quarter of Paris. It was originally the church of a Benedictine abbey founded in the 6th century, by Childebert I, the son of Clovis, King of the Franks. It was destroyed by the Vikings, rebuilt, and renamed in the 8th century for Saint Germain, an early Bishop of the city. It is considered the oldest existing church in Paris.
Church windows are windows within cathedrals, basilicas and other church edifices. They have been a central element in church architecture since Early Christianity.
Early Gothic is a term for the first phase of Gothic style, followed by High Gothic and Late Gothic, dividing the whole Gothic era into three periods. It is defined as a style that used some principle elements of Gothic, but not all. Especially, it had no fine tracery. It marks the first phase of a division of Gothic Style into three periods. If it is used for all countries, it has to be regarded that there may be special terms for the styles of single countries, such as Early English in England.
Romanesque architecture in Spain is the architectural style reflective of Romanesque architecture, with peculiar influences both from architectural styles outside the Iberian peninsula via Italy and France as well as traditional architectural patterns from within the peninsula. Romanesque architecture was developed in and propagated throughout Europe for more than two centuries, ranging approximately from the late tenth century until well into the thirteenth century.
The Bernward Column also known as the Christ Column is a bronze column, made c. 1020 for St. Michael's Church in Hildesheim, Germany, and regarded as a masterpiece of Ottonian art. It was commissioned by Bernward, thirteenth bishop of Hildesheim in 1020, and made at the same time. It depicts images from the life of Jesus, arranged in a helix similar to Trajan's Column: it was originally topped with a cross or crucifix. During the 19th century, it was moved to a courtyard and later to Hildesheim Cathedral. During the restoration of the cathedral from 2010 to 2014, it was moved back to its original location in St. Michael's, but was returned to the Cathedral in August 2014.
The Romanesque style of architecture was introduced in Portugal between the end of the 11th and the beginning of the 12th century. In general, Portuguese cathedrals have a heavy, fortress-like appearance, with crenellations and few decorative elements apart from portals and windows. Portuguese Romanesque cathedrals were later extensively modified, among others the Old Cathedral of Coimbra, although it only had some minor changes.
Romanesque architecture appeared in France at the end of the 10th century, with the development of feudal society and the rise and spread of monastic orders, particularly the Benedictines, which built many important abbeys and monasteries in the style. It continued to dominate religious architecture until the appearance of French Gothic architecture in the Île-de-France between about 1140 and 1150.
A pointed arch, ogival arch, or Gothic arch is an arch with a pointed crown, whose two curving sides meet at a relatively sharp angle at the top of the arch. This architectural element was particularly important in Gothic architecture. The earliest use of a pointed arch dates back to bronze-age Nippur. As a structural feature, it was first used in eastern Christian architecture, Byzantine architecture and Sasanian architecture, but in the 12th century it began to be used in France and England as an important structural element, in combination with other elements, such as the rib vault and later the flying buttress. These allowed the construction of cathedrals, palaces and other buildings with dramatically greater height and larger windows which filled them with light.
A pulvino is an architectural structural element (dosseret) having the shape of an inverted pyramid cushion, which is placed between the column capital and the arch base.
