Alternation of supports is a trait of Romanesque architecture (and Early Gothic [1] ), where the supports in a colonnade or arcade have different types. For example, periodic change between the strong supports (piers) and the weak ones (columns) provides visually obvious alternating supports. More subtle alternation can result, for example, from variations of the column shafts. [2]
An early example of technique used for a decorative purpose can be found in Hagios Demetrios, a 5th century Byzantine church in Thessaloniki. [3] The technique became common at the end of the 10th century [4] and appears to be coupled with the use of transverse arches: [5] the arches rested on the tops of the stronger piers. The double-bay system, with its side aisles at a half of the width of the nave, required columns for the aisle vaults placed at half the step for the transverse arches of the nave, [6] the additional columns sometimes carried smaller load and thus can be thinner.
The use of alternating supports was largely abandoned with the introduction of Gothic architecture and its more malleable pointed arches.[ citation needed ] There were some notable exceptions, however: for example, the lateral aisles of the Notre-Dame de Paris have alternating piers of lower and greater strength that provide a "powerful appeal to the eye and the senses", but had originally fulfilled a structural need, as the heavier piers carried an extra load from the intermediate supports in the buttress system. Also, the alternation can be found in some early Gothic designs of sexpartite vaults, where the support for the middle transverse rib carries less load. [1]
The alternating supports became popular in Europe in the 11th century (early examples started to appear in the 9th century), with the use gradually transitioning from the decorative function to support for the double-bay system. [7]
Italian architecture of the 11th and 12th century actively used the alternating system. However, frequently the column and pier alternation was used for purely decorative purposes, most likely following the Byzantine idea found in the Hagios Demetrios. Examples include San Miniato al Monte (c. 1170), San Clemente al Laterano (dedicated in 1128), Santa Maria in Cosmedin (1123), Basilica di San Nicola in Bari (1197). The alternation was also used structurally, as in Modena Cathedral (1099-1184), probably as an evolution of the decorative use. [3]
The second area of the frequent use of the alternation was Germany, with the earliest example still standing of the church of Saint Cyriakus, Gernrode (c. 960-1014). St. Michael's Church, Hildesheim (1022), Hildesheim Cathedral (1061), and Gandersheim Abbey (1094) form an 11th-century group of churches in Saxony with alternate supports in the "dactyl" arrangement (one pier-two columns in repetition). Dactyl pattern was not new to Saxony in the 11th century, as it was used previously in Gernrode and, likely, in the old Hildesheim Cathedral (852-872). [8] Another group of churches with alternating piers and columns is located in former Lower Lorraine: Abbey of Echternach (1016-1031), church in Zyfflich (early 11th century), Susteren Abbey (mid-11th century), Lobbes Abbey (11th century). The group might also include St Bavo's Cathedral, Ghent. The churches in Lower Lorraine use simple alternation (pier-column) as a base of the double bay system, but without the galleries. A fully developed double bay system with galleries can be found in the church of Soignies. [7]
The use of alternating supports was not common in Normandy, with notable exceptions of Jumièges Abbey (1052-1066) and Lyre Abbey (12th century), [9] the former being an early example of a double-bay transition. [7]
Romanesque architecture is an architectural style of medieval Europe that was predominant in the 11th and 12th centuries. The style eventually developed into the Gothic style with the shape of the arches providing a simple distinction: the Romanesque is characterized by semicircular arches, while the Gothic is marked by the pointed arches. The Romanesque emerged nearly simultaneously in multiple countries ; its examples can be found across the continent, making it the first pan-European architectural style since Imperial Roman architecture. Similarly to Gothic, the name of the style was transferred onto the contemporary Romanesque art.
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.
Cathedrals, collegiate churches, and monastic churches like those of abbeys and priories, often have certain complex structural forms that are found less often in parish churches. They also tend to display a higher level of contemporary architectural style and the work of accomplished craftsmen, and occupy a status both ecclesiastical and social that an ordinary parish church rarely has. Such churches are generally among the finest buildings locally and a source of regional pride. Many are among the world's most renowned works of architecture. These include St Peter's Basilica, Notre-Dame de Paris, Cologne Cathedral, Salisbury Cathedral, Antwerp Cathedral, Prague Cathedral, Lincoln Cathedral, the Basilica of Saint-Denis, Santa Maria Maggiore, the Basilica of San Vitale, St Mark's Basilica, Westminster Abbey, Saint Basil's Cathedral, Antoni Gaudí's incomplete Sagrada Família and the ancient cathedral of Hagia Sophia in Istanbul, now a mosque.
Medieval architecture was the art of designing and constructing buildings in the Middle Ages. Major styles of the period include pre-Romanesque, Romanesque, and Gothic. The Renaissance marked the end of the medieval period, when architects began to favour classical forms. While most surviving medieval constructions are churches and military fortifications, examples of civic and domestic architecture can be found throughout Europe, including in manor houses, town halls, almshouses, bridges, and residential houses.
The flying buttress is a specific form of buttress composed of an arch that extends from the upper portion of a wall to a pier of great mass, in order to convey to the ground the lateral forces that push a wall outwards, which are forces that arise from vaulted ceilings of stone and from wind-loading on roofs.
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.
Tracery is an architectural device by which windows are divided into sections of various proportions by stone bars or ribs of moulding. Most commonly, it refers to the stonework elements that support the glass in a window. The purpose of the device is practical as well as decorative, because the increasingly large windows of Gothic buildings needed maximum support against the wind. The term probably derives from the tracing floors on which the complex patterns of windows were laid out in late Gothic architecture. Tracery can be found on the exterior of buildings as well as the interior.
Speyer Cathedral, officially the Imperial Cathedral Basilica of the Assumption and St Stephen, in Latin: Domus sanctae Mariae Spirae in Speyer, Germany, is the seat of the Roman Catholic Bishop of Speyer and is suffragan to the Roman Catholic Archdiocese of Bamberg. The cathedral, which is dedicated to St. Mary, patron saint of Speyer and St. Stephen is generally known as the Kaiserdom zu Speyer. Pope Pius XI raised Speyer Cathedral to the rank of a minor basilica of the Roman Catholic Church in 1925.
The larger medieval churches of France and England, the cathedrals and abbeys, have much in common architecturally, an east–west orientation, an external emphasis on the west front and its doors, long arcaded interiors, high vaulted roofs and windows filled with stained glass. The eastern end of the building contains the Sanctuary and the Altar.
In architecture, a vault is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. Until the topmost voussoir, the keystone, is positioned, the vault is not self-supporting. Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or segmental head, which supports the voussoirs until the ring of the whole arch is completed.
French architecture consists of architectural styles that either originated in France or elsewhere and were developed within the territories of France.
The Basilica di San Zeno is a minor basilica of Verona, northern Italy constructed between 967 and 1398 AD. Its fame rests partly on its Romanesque architecture and partly upon the tradition that its crypt was the place of the marriage of Shakespeare's Romeo and Juliet. It stands adjacent to a Benedictine abbey, both dedicated to St Zeno of Verona.
English Gothic is an architectural style that flourished from the late 12th until the mid-17th century. The style was most prominently used in the construction of cathedrals and churches. Gothic architecture's defining features are pointed arches, rib vaults, buttresses, and extensive use of stained glass. Combined, these features allowed the creation of buildings of unprecedented height and grandeur, filled with light from large stained glass windows. Important examples include Westminster Abbey, Canterbury Cathedral and Salisbury Cathedral. The Gothic style endured in England much longer than in Continental Europe.
Gothic architecture appeared in the prosperous independent city-states of Italy in the 12th century, at the same time as it appeared in Northern Europe. In fact, unlike in other regions of Europe, it did not replace Romanesque architecture, and Italian architects were not very influenced by it. However, each city developed its own particular variations of the style. Italian architects preferred to keep the traditional construction methods established in the previous centuries; architectural solutions and technical innovations of French Gothic were seldom used. Soaring height was less important than in Northern Europe. Brick rather than stone was the most common building material, and marble was widely used for decoration. In the 15th century, when the Gothic style dominated both Northern Europe and the Italian Peninsula, Northern Italy became the birthplace of Renaissance architecture.
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.
Saint Cyriakus is a medieval church in Gernrode, Saxony-Anhalt, Germany. It is one of the few surviving examples of Ottonian architecture, built in 959/960–965 by Margrave Gero, although it was restored in the 19th century. From its foundation until 1614, Saint Cyriakus was the collegiate church of the Abbey of Gernrode, also founded by Margrave Gero. The church and the abbey became Protestant in the mid-sixteenth century, and the church is now used by the Protestant community of Gernrode.
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.
Gothic cathedrals and churches are religious buildings created in Europe between the mid-12th century and the beginning of the 16th century. The cathedrals are notable particularly for their great height and their extensive use of stained glass to fill the interiors with light. They were the tallest and largest buildings of their time and the most prominent examples of Gothic architecture. The appearance of the Gothic cathedral was not only a revolution in architecture; it also introduced new forms in decoration, sculpture, and art.
