Squinches
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 ...

History Of Persian Domes
Persian domes or Iranian domes have an ancient origin and a history extending to the modern era. The use of domes in ancient Mesopotamia was carried forward through a succession of empires in the Greater Iran region. An ancient tradition of royal audience tents representing the heavens was translated into monumental stone and brick domes due to the invention of the squinch, a reliable method of supporting the circular base of a heavy dome upon the walls of a square chamber. Domes were built as part of royal palaces, castles, caravansaries, and temples, among other structures. With the Muslim conquest of Persia, introduction of Islam in the 7th century, mosque and mausoleum architecture also adopted and developed these forms. Structural innovations included pointed domes, drums, conical roofs, double and triple shells, and the use of muqarnas and bulbous forms. Decorative brick patterning, interlaced ribs, painted plaster, and colorful tiled mosaics were used to decorate the exteri ...

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, ...

History Of Roman And Byzantine Domes
Domes were a characteristic element of the architecture of Ancient Rome and of its medieval continuation, the Byzantine Empire. They had widespread influence on contemporary and later styles, from Russian and Ottoman architecture to the Italian Renaissance and modern revivals. The domes were customarily hemispherical, although octagonal and segmented shapes are also known, and they developed in form, use, and structure over the centuries. Early examples rested directly on the rotunda walls of round rooms and featured a central oculus for ventilation and light. Pendentives became common in the Byzantine period, provided support for domes over square spaces. Early wooden domes are known only from a literary source, but the use of wooden formwork, concrete, and unskilled labor enabled domes of monumental size in the late Republic and early Imperial period, such as the so-called "Temple of Mercury" bath hall at Baiae. Nero introduced the dome into Roman palace architecture in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muqarnas
Muqarnas (), also known in Iberian architecture as Mocárabe (from ), is a form of three-dimensional decoration in Islamic architecture in which rows or tiers of niche-like elements are projected over others below. It is an archetypal form of Islamic architecture, integral to the vernacular of Islamic buildings, and typically featured in domes and vaults, as well as iwans, entrance portals, or other niches. It is sometimes referred to as "honeycomb vaulting" or "stalactite vaulting". The muqarnas structure originated from the squinch. Its purpose is to create a smooth, decorative zone of transition in an otherwise bare, structural space. This structure gives the ability to distinguish between the main parts of a building and serves as a transition from the walls of a square or rectangular room to a round dome or vault above it. Muqarnas could also form entire vaults and domes. From below, these compositions can create an elaborate visual effect based on the interplay of light ...

Baptistery Of San Giovanni In Fonte, Naples
The Baptistery of San Giovanni is a Early Christianity, Paleochristian baptistery attached to the Santa Restituta church in Naples, Italy. It is the oldest surviving baptistery from medieval Europe. History The baptistery was likely built in the fourth century. There are conflicting accounts of who commissioned the construction of the baptistery and when. Severus of Naples, Severus, the twelfth bishop of Naples, is often credited with its construction in the late fourth century. The construction of the baptistery by Severus is chronicled in John the Deacon (Neapolitan historian), John the Deacon’s ''Gesta episcoporum Neapolitanorum''. However, the thirteenth–fourteenth century work ''Chronicle of Saint Mary of the Principle'', credits Constantine the Great with the building of the baptistery at the same time as the S. Restituta during the early fourth century. The architecture and mosaic style lead researchers to believe that the baptistery was more likely to have been co ...

Odzun Cupola
Odzun () is a village in the Lori Province of Armenia. It is situated on a plateau above the left bank of the Debed river gorge, about a thousand metres above the Yerevan–Tbilisi highway, a few kilometres south of the town of Alaverdi. It is famous for the 6th–8th-century Odzun Church, an Armenian basilica with a cupola, overlooking the gorge. Name According to one explanation, the name of the village derives from the Armenian word 'snake'; thus, ''Odzun'' means 'having many snakes' or 'place of snakes'. The name of the village is attested in various forms, such as ''Otsun'', ''Ozun'', ''Adzun'' and ''Udzun''. Turkic speakers called the village ''Uzunlar'', formed by etymological reinterpretation of the Armenian name (''uzun'' means 'tall' or 'long', and ''-lar'' is a plural-forming suffix). The village was officially known by this latter name from the beginning of the 19th century until 1967, when it was renamed ''Odzun''. Geography Topography The village is situate ...

History Of Early And Simple Domes
Cultures from pre-history to modern times constructed domed dwellings using local materials. Although it is not known when or where the first dome was created, sporadic examples of early domed structures have been discovered. Brick domes from the ancient Near East and corbelled stone domes have been found from the Middle East to Western Europe. These may indicate a common source or multiple independent traditions. A variety of materials have been used, including wood, mudbrick, or fabric. Indigenous peoples around the world produce similar structures today. Early and indigenous domes The earliest domes were likely domed huts made from saplings, reeds, or timbers and covered with thatch, turf, or skins. Materials may have transitioned to rammed earth, mud-brick, or more durable stone as a result of local conditions. The earliest discovered remains of domed constructions may be four small dwellings made of Mammoth tusks and bones. The first was found by a farmer in Mezhirich, Ukra ...
