Spandrels
A spandrel is a roughly triangular space, usually found in pairs, between the top of an arch and a rectangular frame, between the tops of two adjacent arches, or one of the four spaces between a circle within a square. They are frequently filled with decorative elements. Meaning There are four or five accepted and cognate meanings of the term ''spandrel'' in architectural and art history, mostly relating to the space between a curved figure and a rectangular boundary – such as the space between the curve of an arch and a rectilinear bounding moulding, or the wallspace bounded by adjacent arches in an arcade and the stringcourse or moulding above them, or the space between the central medallion of a carpet and its rectangular corners, or the space between the circular face of a clock and the corners of the square revealed by its hood. Also included is the space under a flight of stairs, if it is not occupied by another flight of stairs. In a building with more than one floo ...

Spandrel (biology)
In evolutionary biology, a spandrel is a phenotypic trait that is a byproduct of the evolution of some other characteristic, rather than a direct product of adaptive selection. Stephen Jay Gould and Richard Lewontin brought the term into biology in their 1979 paper " The Spandrels of San Marco and the Panglossian Paradigm: A Critique of the Adaptationist Programme". Adaptationism is a point of view that sees most organismal traits as adaptive products of natural selection. Gould and Lewontin sought to temper what they saw as adaptationist bias by promoting a more structuralist view of evolution. The term "spandrel" originates from architecture, where it refers to the roughly triangular spaces between the top of an arch and the ceiling. Etymology The term was coined by paleontologist Stephen Jay Gould and population geneticist Richard Lewontin in their paper "The Spandrels of San Marco and the Panglossian Paradigm: A Critique of the Adaptationist Programme" (1979).

Magdalen College, Oxford
Magdalen College ( ) is a Colleges of the University of Oxford, constituent college of the University of Oxford. It was founded in 1458 by Bishop of Winchester William of Waynflete. It is one of the wealthiest Oxford colleges, as of 2022, and one of the strongest academically, setting the record for the highest Norrington Table, Norrington Score in 2010 and topping the table twice since then. It is home to several of the university's distinguished Chair (academic), chairs, including the Serena Professor of Italian#Serena Professors at Oxford, Agnelli-Serena Professorship, the Sherardian Professor of Botany, Sherardian Professorship, and the four Waynflete Professorships. The large, square Magdalen Tower is an Oxford landmark, and it is a tradition, dating to the days of Henry VII of England, Henry VII, that the college choir sings from the top of it at 6 a.m. on May Morning. The college stands next to the River Cherwell and the University of Oxford Botanic Garden. Within i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skeuomorph
A skeuomorph (also spelled skiamorph, ) is a derivative object that retains ornamental design cues (attributes) from structures that were necessary in the original. Skeuomorphs are typically used to make something new feel familiar in an effort to speed understanding and acclimation. They employ elements that, while essential to the original object, serve no pragmatic purpose in the new system, except for identification. Examples include pottery embellished with imitation rivets reminiscent of similar pots made of metal and a software calendar that imitates the appearance of binding on a paper desk calendar. Definition and purpose The term ''skeuomorph'' is compounded from the Greek ''skeuos'' (σκεῦος), meaning "container or tool", and ''morphḗ'' (μορφή), meaning "shape". It has been applied to material objects since 1890. With the advent of graphical computer systems in the 1980s, skeuomorph is used to characterize the many "old fashioned" icons utilized in graphi ...

Squinch
In architecture, a squinch is a structural element used to support the base of a circular or octagonal dome that surmounts a square-plan chamber. Squinches are placed to diagonally span each of the upper internal corners ( vertices) where the walls meet. Constructed from masonry, they have several forms, including a graduated series of stepped arches; a hollow, open half-cone (like half of a funnel laid horizontally); or a small half-dome niche. They are designed to evenly spread the load of a dome across the intersecting walls on which it rests, thus avoiding concentrating higher structural stress on smaller load-bearing areas. By bridging corners, they also visually transition an angular space to a round or near-circular zone. Squinches originated in the Sassanid Empire of Ancient Persia, remaining in use across Central and West Asia into modern times. From its pre-Islamic origin, it developed into an influential structure for Islamic architecture. Georgia and Armenia also in ...

Cathedral Architecture
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.

Voussoirs
A voussoir (British English, UK: ; American English, US: ) is a wedge-shaped element, typically a stone, which is used in building an arch or vault (architecture), vault.“Voussoir, N., Pronunciation.” Oxford English Dictionary, Oxford University Press, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 24 Mar. 2025. Although each unit in an arch or vault is a voussoir, two units are of distinct functional importance: the Keystone (architecture), keystone and the Springer (architecture), springer. The keystone is the centre stone or masonry unit at the apex of an arch. The springer is the lowest voussoir on each side, located where the curve of the arch springs from the vertical support or abutment of the wall or pier (architecture), pier. The keystone is often decorated or enlarged. An enlarged and sometimes slightly dropped keystone is often found in Mannerism, Mannerist arches of the 16th century, beginning with the works of Giulio Romano (painter), Giu ...

Alfiz
The alfiz (, from Andalusi Arabic ''alḥíz'', from Standard Arabic ''alḥáyyiz'', meaning 'the container'; "''DRAE. Diccionario de la Lengua Española. Vigésima segunda edición''", Espasa Calpe, S.A, 2003) is an architectural adornment, consisting of a moulding, usually a rectangular panel, which encloses the outward side of an arch. It is an architectonic ornament of Etruscan origin, used in , Asturian, |
Pendentives
In architecture, a pendentive is a constructional device permitting the placing of a circular dome over a square room or of an elliptical dome over a rectangular room. The pendentives, which are triangular segments of a sphere, taper to points at the bottom and spread at the top to establish the continuous circular or elliptical base needed for a dome. In masonry the pendentives thus receive the weight of the dome, concentrating it at the four corners where it can be received by the piers beneath. Prior to the pendentive's development, builders used the device of corbelling or squinches in the corners of a room. Pendentives commonly occurred in Orthodox, Renaissance, and Baroque churches, with a drum with windows often inserted between the pendentives and the dome. The first experimentation with pendentives began with Roman dome construction in the 2nd–3rd century AD, while full development of the form came in the 6th-century Eastern Roman cathedral, Hagia Sophia, i ...

Dome
A dome () is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them. A dome can rest directly upon a Rotunda (architecture), rotunda wall, a Tholobate, drum, or a system of squinches or pendentives used to accommodate the transition in shape from a rectangular or square space to the round or polygonal base of the dome. The dome's apex may be closed or may be open in the form of an Oculus (architecture), oculus, which may itself be covered with a roof lantern and cupola. Domes have a long architectural lineage that extends back into prehistory. Domes were built in ancient Mesopotamia, and they have been found in Persian architecture, Persian, Ancient Greek architecture, Hellenistic, Ancient Roman architecture, ...

Decorated Period
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. The Gothic style was introduced from France, where the various elements had first been used together within a single building at the choir of the Abbey of Saint-Denis north of Paris, completed in 1144. The earliest large-scale applications of Gothic architecture in England were Canterbury Cathedral and Westminster Abbey. Many features of Gothic architecture had e ...

Perpendicular Style
Perpendicular Gothic (also Perpendicular, Rectilinear, or Third Pointed) 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-Irish 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. The pointed arches used in Perpendicular were often four-centred arches, allowing them to be rather wider and flatter than in other Gothic styles. Perpendicular tracery is characterized by mullions that rise verticall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
