Semi-dome
In architecture, a semi-dome (or half-dome) is a half dome that covers a semi-circular area in a building. Architecture Semi-domes are a common feature of apses in Ancient Roman and traditional church architecture, and in mosques and iwans in Islamic architecture. A semi-dome, or the whole apse, may also be called a conch after the scallop shell often carved as decoration of the semi-dome (all shells were conches in Ancient Greek), though this is usually used for subsidiary semi-domes, rather than the one over the main apse. Small semi-domes have been often decorated in a shell shape from ancient times, as in Piero della Francesca's ''Throned Madonna with saints and Federigo da Montefeltro'', and the example in the gallery below. Islamic examples may use muqarnas decorative corbelling, while in Late Antique, Byzantine and medieval church architecture the semi-dome is the classic location for a focal mosaic, or later fresco. Found in many Ancient Greek exedras, the semi-dome bec ...

Ottoman Architecture
Ottoman architecture is the architectural style that developed under the Ottoman Empire. It first emerged in northwestern Anatolia in the late 13th century and developed from earlier Seljuk architecture, Seljuk Turkish architecture, with influences from Byzantine architecture, Byzantine and Iranian architecture, Iranian architecture along with other architectural traditions in the Middle East.: "The grand tradition of Ottoman architecture, established in the 16th century, differed markedly from that of the earlier Moors. It was derived from both the Byzantine Christian tradition, outlined above, and native Middle Eastern forms used by the Islamic Seljuk Turks, who preceded the Ottomans. The Byzantine tradition, particularly as embodied in Hagia Sophia, was perhaps the major source of inspiration." "The mosques of the classical period are more elaborate than those of earlier times. They derive from a fusion of a native Turkish tradition with certain elements of the plan of Haghia S ...

Hagia Sophia
Hagia Sophia ( 'Holy Wisdom'; ; ; ), officially the Hagia Sophia Grand Mosque ( tr, Ayasofya-i Kebir Cami-i Şerifi), is a mosque and major cultural and historical site in Istanbul, Turkey. The cathedral was originally built as a Greek Orthodox church which lasted from 360 AD until the conquest of Constantinople by the Ottoman Empire in 1453. It served as a mosque until 1935, when it became a museum. In 2020, the site once again became a mosque. The current structure was built by the eastern Roman emperor Justinian I as the Christian cathedral of Constantinople for the state church of the Roman Empire between 532 and 537, and was designed by the Greek geometers Isidore of Miletus and Anthemius of Tralles. It was formally called the Church of the Holy Wisdom () and upon completion became the world's largest interior space and among the first to employ a fully pendentive dome. It is considered the epitome of Byzantine architecture and is said to have "changed the history o ...

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, ...

Mimar Sinan
Mimar Sinan ( ota, معمار سينان, translit=Mi'mâr Sinân, , ) ( 1488–1490 – 17 July 1588) also known as Koca Mi'mâr Sinân Âğâ, ("Sinan Agha (title), Agha the Grand Architect" or "Grand Sinan") was the chief Ottoman Empire, Ottoman architect ( tr, links=no, mimar) and civil engineer for sultans Suleiman the Magnificent, Selim II and Murad III. He was responsible for the construction of more than 300 major structures and other more modest projects, such as schools. His apprentices would later design the Sultan Ahmed Mosque in Istanbul and Stari Most in Mostar. The son of a stonemason, he received a technical education and became a military engineer. He rose rapidly through the ranks to become first an officer and finally a Janissary commander, with the honorific title of Sinan.Goodwin (2001), p. 87 He refined his architectural and engineering skills while on campaign with the Janissaries, becoming expert at constructing fortifications of all kinds, as well ...

Islamic Architecture
Islamic architecture comprises the architectural styles of buildings associated with Islam. It encompasses both secular and religious styles from the early history of Islam to the present day. The Islamic world encompasses a wide geographic area historically ranging from western Africa and Europe to eastern Asia. Certain commonalities are shared by Islamic architectural styles across all these regions, but over time different regions developed their own styles according to local materials and techniques, local dynasties and patrons, different regional centers of artistic production, and sometimes different religious affiliations. Early Islamic architecture was influenced by Roman, Byzantine, Iranian, and Mesopotamian architecture and all other lands which the Early Muslim conquests conquered in the seventh and eighth centuries.: "As the Arabs did not have an architectural tradition suited to the needs of a great empire, they adopted the building methods of the defeated Sassan ...

Church Architecture
Church architecture refers to the architecture of buildings of churches, convents, seminaries etc. It has evolved over the two thousand years of the Christian religion, partly by innovation and partly by borrowing other architectural styles as well as responding to changing beliefs, practices and local traditions. From the birth of Christianity to the present, the most significant objects of transformation for Christian architecture and design were the great churches of Byzantium, the Romanesque abbey churches, Gothic cathedrals and Renaissance basilicas with its emphasis on harmony. These large, often ornate and architecturally prestigious buildings were dominant features of the towns and countryside in which they stood. However, far more numerous were the parish churches in Christendom, the focus of Christian devotion in every town and village. While a few are counted as sublime works of architecture to equal the great cathedrals and churches, the majority developed along si ...

Apse
In architecture, an apse (plural apses; from Latin 'arch, vault' from Ancient Greek 'arch'; sometimes written apsis, plural apsides) is a semicircular recess covered with a hemispherical vault or semi-dome, also known as an ''exedra''. In Byzantine, Romanesque, and Gothic Christian church (including cathedral and abbey) architecture, the term is applied to a semi-circular or polygonal termination of the main building at the liturgical east end (where the altar is), regardless of the shape of the roof, which may be flat, sloping, domed, or hemispherical. Smaller apses are found elsewhere, especially in shrines. Definition An apse is a semicircular recess, often covered with a hemispherical vault. Commonly, the apse of a church, cathedral or basilica is the semicircular or polygonal termination to the choir or sanctuary, or sometimes at the end of an aisle. Smaller apses are sometimes built in other parts of the church, especially for reliquaries or shrines of saints. Hi ...

Triconch
A tetraconch, from the Greek for "four shells", is a building, usually a church or other religious building, with four apses, one in each direction, usually of equal size. The basic ground plan of the building is therefore a Greek cross. They are most common in Byzantine, and related schools such as Armenian and Georgian architecture. It has been argued that they were developed in these areas or Syria, and the issue is a matter of contention between the two nations in the Caucasus. Apart from churches, the form is suitable for a mausoleum or baptistery. Normally, there will be a higher central dome over the central space. Overview The Basilica of San Lorenzo, Milan (370) is possibly the first example of a grander type, the "aisled tetraconch", with an outer ambulatory. In middle Byzantine architecture, the cross-in-square plan was developed, essentially filling out the tetraconch to form a square-ish exterior. Either of these types may also be described less precisely as "cross-do ...

Exedra
An exedra (plural: exedras or exedrae) is a semicircular architectural recess or platform, sometimes crowned by a semi-dome, and either set into a building's façade or free-standing. The original Greek sense (''ἐξέδρα'', a seat out of doors) was applied to a room that opened onto a stoa, ringed with curved high-backed stone benches, a suitable place for conversation. An exedra may also be expressed by a curved break in a colonnade, perhaps with a semicircular seat. The exedra would typically have an apsidal podium that supported the stone bench. The free-standing (open air) exedra, often supporting bronze portrait sculpture, is a familiar Hellenistic structure, characteristically sited along sacred ways or in open places in sanctuaries, such as at Delos or Epidaurus. Some Hellenistic exedras were built in relation to a city's agora, as in Priene. Monument architects have also used this free-standing style in modern times. Rise The exedra achieved particular populari ...

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. Characteristic ...

Mosaic
A mosaic is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster/mortar, and covering a surface. Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world. Mosaic today includes not just murals and pavements, but also artwork, hobby crafts, and industrial and construction forms. Mosaics have a long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome. Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics. Mosaic art flourished in the Byzantine Empire from the 6th to the 15th centuries; that tradition was adopted by the Norman Kingdom of Sicily in the 12th century, by the eastern-influenced Republic of Venice, and among the Rus. Mosaic fell ou ...
