In architecture, a boss is a decorative knob on a ceiling, wall or sculpture.
Bosses can often be found in the ceilings of buildings, particularly at the keystones at the intersections of a rib vault. [1] In Gothic architecture, such roof bosses (or ceiling bosses) are often intricately carved with foliage, heraldic devices or other decorations. Many feature animals, birds, or human figures or faces, sometimes realistic, but often Grotesque: the Green Man is a frequent subject. [2]
The Romanesque Norwich Cathedral in Norfolk, United Kingdom, has the largest number of painted carved stone bosses in the world; an extensive and varied collection of over one thousand individual pieces. Many of these decorated bosses still bear the original gilt and pigments from the time of their creation.
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.
The architecture of cathedrals and great churches is characterised by the buildings' large scale and follows one of several branching traditions of form, function and style that derive ultimately from the Early Christian architectural traditions established in Late Antiquity during the Christianisation of the Roman Empire.
The Green Man, also known as a foliate head, is a motif in architecture and art, of a face made of, or completely surrounded by, foliage, which normally spreads out from the centre of the face. Apart from a purely decorative function, the Green Man is primarily interpreted as a symbol of rebirth, representing the cycle of new growth that occurs every spring.
A keystone is the wedge-shaped stone at the apex of a masonry arch or typically round-shaped one at the apex of a vault. In both cases it is the final piece placed during construction and locks all the stones into position, allowing the arch or vault to bear weight. In arches and vaults keystones are often enlarged beyond the structural requirements and decorated. A variant in domes and crowning vaults is a lantern.
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.
A chapter house or chapterhouse is a building or room that is part of a cathedral, monastery or collegiate church in which meetings are held. When attached to a cathedral, the cathedral chapter meets there. In monasteries, the whole community often met there daily for readings and to hear the abbot or senior monks talk. When attached to a collegiate church, the dean, prebendaries and canons of the college meet there. The rooms may also be used for other meetings of various sorts; in medieval times monarchs on tour in their territory would often take them over for their meetings and audiences. Synods, ecclesiastical courts and similar meetings often took place in chapter houses.
Linköping Cathedral is an active Lutheran church in the Swedish city of Linköping, the episcopal seat of the Diocese of Linköping in the Church of Sweden. One of the largest Gothic cathedrals in Europe, it is situated opposite Linköping Castle, on a site that has been in use as a church since the 11th century.
In French Gothic architecture, the Rayonnant style is the third of the four phases of Gothic architecture in France, as defined by French scholars. Related to the English division of Continental Gothic into three phases, it is the second and larger part of High Gothic.
Romanesque art is the art of Europe from approximately 1000 AD to the rise of the Gothic style in the 12th century, or later depending on region. The preceding period is known as the Pre-Romanesque period. The term was invented by 19th-century art historians, especially for Romanesque architecture, which retained many basic features of Roman architectural style – most notably round-headed arches, but also barrel vaults, apses, and acanthus-leaf decoration – but had also developed many very different characteristics. In Southern France, Spain, and Italy there was an architectural continuity with the Late Antique, but the Romanesque style was the first style to spread across the whole of Catholic Europe, from Sicily to Scandinavia. Romanesque art was also greatly influenced by Byzantine art, especially in painting, and by the anti-classical energy of the decoration of the Insular art of the British Isles. From these elements was forged a highly innovative and coherent style.
French architecture consists of numerous architectural styles that either originated in France or elsewhere and were developed within the territories of France.
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.
French Gothic architecture is an architectural style which emerged in France in 1140, and was dominant until the mid-16th century. The most notable examples are the great Gothic cathedrals of France, including Notre-Dame Cathedral, Reims Cathedral, Chartres Cathedral, and Amiens Cathedral. Its main characteristics are verticality, or height, and the innovative use of the rib vault and flying buttresses and other architectural innovations to distribute the weight of the stone structures to supports on the outside, allowing unprecedented height and volume. The new techniques also permitted the addition of larger windows, including enormous stained glass windows, which fill the cathedrals with light.
The medieval cathedrals of England, which date from between approximately 1040 and 1540, are a group of twenty-six buildings that constitute a major aspect of the country's artistic heritage and are among the most significant material symbols of Christianity. Though diverse in style, they are united by a common function. As cathedrals, each of these buildings serves as central church for an administrative region and houses the throne of a bishop. Each cathedral also serves as a regional centre and a focus of regional pride and affection.
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 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.
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.
Perpendicular Gothic architecture was the third and final style of English Gothic architecture developed in the Kingdom of England during the Late Middle Ages, typified by large windows, four-centred arches, straight vertical and horizontal lines in the tracery, and regular arch-topped rectangular panelling. Perpendicular was the prevailing style of Late Gothic architecture in England from the 14th century to the 17th century. Perpendicular was unique to the country: no equivalent arose in Continental Europe or elsewhere in the British Isles. Of all the Gothic architectural styles, Perpendicular was the first to experience a second wave of popularity from the 18th century on in Gothic Revival architecture.
