Pulvino
A pulvino (or impost block) 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. Overview Usually decorated with fretwork or relief ornamental motifs, the pulvino reaches its maximum expression in the Byzantine architecture; some examples can be found in the early Christian architecture of Ravenna. Its particular convex shape gives the pulvino the structural function of concentrating the tensions generated by the loads above it and passing the tensions on the column located below the capital. An example can be seen in the church of San Lorenzo in Florence designed by Filippo Brunelleschi around 1420. There he resorted to additional segments of entablature improperly defined as "Brunelleschian nut". The pulvino in this case created a balanced entablature, on which the round arches are set. Modern engineering By analogy with the static function of the pulvino on a column, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abacus (architecture)
In architecture, an abacus (from the Greek ''abax'', slab; or French ''abaque'', ''tailloir''; plural abacuses or abaci) 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. Definition In classical architecture, the shape of the abacus and its edge profile varies in the different classical orders. In the Greek Doric order, the abacus is a plain square slab without mouldings, supported on an echinus. In the Roman and Renaissance Doric orders, it is crowned by a moulding (known as "crown moulding"). In the Tuscan and Roman Doric capital, it may r ...

Capital (architecture)
In architecture the capital (from the Latin ''caput'', or "head") or chapiter forms the topmost member of a column (or a pilaster). 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. From the highly visible position it occupies in all colonnaded monumental buildings, the capital is often selected for ornamentation; and is often the clearest indicator of the architectural orde ...

Impost (architecture)
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. Ornamental training The imposts are left smooth or profiled, and "then express a certain separation between abutment and arch." 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.

Waterleaf (architecture)
In architecture, a waterleaf is a distinctive sculptural motif used on the capitals of columns and pilasters in European buildings during the late twelfth century. It is a highly simplified plant motif, characteristic of the "late Norman" style of Romanesque architecture. A waterleaf capital is formed of broad, smooth leaf-shapes (typically four in number), unribbed except for a central fold, which curve upward and outward before curling over at the tips where they meet the abacus (the flat slab at the top of the column, normally square but sometimes octagonal). The curled tip of the waterleaf may be small and neat or large and bulbous; it usually curves inward towards the abacus, but may occasionally turn outwards (both forms can sometimes be seen in adjacent capitals of the same period, as for example at Geddington, Northamptonshire, UK.

Ravenna San Vitale 202
Ravenna ( , , also ; rgn, Ravèna) is the capital city of the Province of Ravenna, in the Emilia-Romagna region of Northern Italy. It was the capital city of the Western Roman Empire from 408 until its collapse in 476. It then served as the capital of the Ostrogothic Kingdom until it was re-conquered in 540 by the Byzantine Empire. Afterwards, the city formed the centre of the Byzantine Exarchate of Ravenna until the last exarch was executed by the Lombards in 751. Although it is an inland city, Ravenna is connected to the Adriatic Sea by the Candiano Canal. It is known for its well-preserved late Roman and Byzantine architecture, with eight buildings comprising the UNESCO World Heritage Site "Early Christian Monuments of Ravenna". History The origin of the name ''Ravenna'' is unclear. Some have speculated that "Ravenna" is related to "Rasenna" (or "Rasna"), the term that the Etruscans used for themselves, but there is no agreement on this point. Ancient era The origins of Ra ...

Fretwork
Fretwork is an interlaced decorative design that is either carved in low relief on a solid background, or cut out with a fretsaw, coping saw, jigsaw or scroll saw. Most fretwork patterns are geometric in design. The materials most commonly used are wood and metal. Fretwork is used to adorn furniture and musical instruments. The term is also used for tracery on glazed windows and doors. Fretwork is also used to adorn/decorate architecture, where specific elements of decor are named according to their use such as eave bracket, gable fretwork or baluster fretwork, which may be of metal, especially cast iron or aluminum. Installing elaborate wooden fretworks on residential buildings, known as gingerbread trims, became popular in North America North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the ...

Byzantine Architecture
Byzantine architecture is the architecture of the Byzantine Empire, or Eastern Roman Empire. The Byzantine era is usually dated from 330 AD, when Constantine the Great moved the Roman capital to Byzantium, which became Constantinople, until the fall of the Byzantine Empire in 1453. However, there was initially no hard line between the Byzantine and Roman empires, and early Byzantine architecture is stylistically and structurally indistinguishable from earlier Roman architecture. This terminology was introduced by modern historians to designate the medieval Roman Empire as it evolved as a distinct artistic and cultural entity centered on the new capital of Constantinople (modern-day Istanbul) rather than the city of Rome and its environs. Its architecture dramatically influenced the later medieval architecture throughout Europe and the Near East, and became the primary progenitor of the Renaissance and Ottoman architectural traditions that followed its collapse.

San Lorenzo, Florence
The Basilica di San Lorenzo (Basilica of St. Lawrence) is one of the largest churches of Florence, Italy, situated at the centre of the main market district of the city, and it is the burial place of all the principal members of the Medici family from Cosimo il Vecchio to Cosimo III. It is one of several churches that claim to be the oldest in Florence, having been consecrated in 393 AD, at which time it stood outside the city walls. For three hundred years it was the city's cathedral, before the official seat of the bishop was transferred to Santa Reparata. San Lorenzo was the parish church of the Medici family. In 1419, Giovanni di Bicci de' Medici offered to finance a new church to replace an eleventh-century Romanesque rebuilding. Filippo Brunelleschi, the leading Renaissance architect of the first half of the fifteenth century, was commissioned to design it, but the building, with alterations, was not completed until after his death. The church is part of a larger monast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filippo Brunelleschi
Filippo Brunelleschi ( , , also known as Pippo; 1377 – 15 April 1446), considered to be a founding father of Renaissance architecture, was an Italian architect, designer, and sculptor, and is now recognized to be the first modern engineer, planner, and sole construction supervisor. In 1421, Brunelleschi became the first person to receive a patent in the Western world. He is most famous for designing the dome of the Florence Cathedral, a feat of engineering that had not been accomplished since antiquity, as well as the development of the mathematical technique of linear perspective in art which governed pictorial depictions of space until the late 19th century and influenced the rise of modern science. His accomplishments also include other architectural works, sculpture, mathematics, engineering, and ship design. His principal surviving works can be found in Florence. Biography Early life Brunelleschi was born in Florence, Italy, in 1377. His family consisted of his father, B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Sofia, Benevento
Santa Sofia is a Roman Catholic church in the town of Benevento, in the region of Campania, in southern Italy; founded in the late-8th century, it retains many elements of its original Lombard architecture. In 2011, it became a UNESCO World Heritage Site as part of a group of seven inscribed as Longobards in Italy. Places of the power (568-774 A.D.). History The church was founded by the Lombards, Lombard Arechis II of Benevento around 760, as testified by numerous privileges signed by him, some of which are in the Museum of Samnium near the church. The edifice was modeled on the Palatine Chapel of the Lombard king Liutprand, King of the Lombards, Liutprand in Pavia and, after the defeat of Desiderius by Charlemagne and the fall of the Lombard kingdom in northern Italy (774), it became the national church of the Lombards who had taken shelter in the Duchy of Benevento. The church was part of a large program of construction which would legitimate Arechis' claim as the highest Lomb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
