Cathedral Of Avan
The Cathedral of Avan () is a ruined late 6th-century church located in the Avan District of Yerevan, the capital of Armenia. It is the oldest surviving church inside Yerevan's city limits. History The church was built by Todosak in the late 6th century, between the years 591 and 602. The construction began soon after the conclusion of the long Byzantine–Sasanian War of 572–591, that resulted in expansion of direct Byzantine rule over all western regions of Armenia, as far as Avan. In order to strengthen political control over newly conquered regions, emperor Maurice () decided to support the pro-Chalcedonian fraction of the Armenian Church. In 593, a regional council of western Armenian bishops was convened in Theodosiopolis, which proclaimed allegiance to the Chalcedonian Definition. The council elected John (Yovhannes, or Hovhannes) of Bagaran, as new Catholicos of Chalcedonian Armenians. Since the headquarters of his rival, the pro-Persian Catholicos Moses II (574� ...

Avan District
Avan () is one of the Districts of Yerevan, 12 districts of Yerevan, the capital of Armenia. Originally an ancient village on a hill at the northeastern outskirts of Yerevan, Avan has been inhabited since pre-Christian times. In the 20th century, during the Soviet Union, Soviet period, the village was incorporated into the capital Yerevan. According to the 2022 census, Avan has a population of 55,094.

Khosrau II
Khosrow II (spelled Chosroes II in classical sources; and ''Khosrau''), commonly known as Khosrow Parviz (New Persian: , "Khosrow the Victorious"), is considered to be the last great Sasanian King of Kings (Shahanshah) of Iran, ruling from 590 to 628, with an interruption of one year. Khosrow II was the son of Hormizd IV (reigned 579–590), and the grandson of Khosrow I (reigned 531–579). He was the last king of Iran to have a lengthy reign before the Muslim conquest of Iran, which began five years after his execution. He lost his throne, then recovered it with the help of the Byzantine emperor Maurice, and, a decade later, went on to emulate the feats of the Achaemenids, conquering the rich Roman provinces of the Middle East; much of his reign was spent in wars with the Byzantine Empire and struggling against usurpers such as Bahram Chobin and Vistahm. Khosrow II began a war against the Byzantines in 602, ostensibly to avenge the murder of his ally Maurice. Persian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunette
A lunette (French ''lunette'', 'little moon') is a crescent- or half-moon–shaped or semi-circular architectural space or feature, variously filled with sculpture, painted, glazed, filled with recessed masonry, or void. A lunette may also be segmental, and the arch may be an arc taken from an oval. A lunette window is commonly called a ''half-moon window'', or fanlight when bars separating its panes fan out radially. If a door is set within a round-headed arch, the space within the arch above the door, masonry or glass is a lunette. If the door is a major access, and the lunette above is massive and deeply set, it may be called a Tympanum (architecture), tympanum. A lunette is also formed when a horizontal cornice (architecture), cornice transects a round-headed arch at the level of the Impost (architecture), imposts, where the arch springs. If the top of the lunette itself is bordered by a hood mould it can also be considered a pediment. The term is also employed to descri ...

Capital (architecture)
In architecture, the capital () 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 was formalized in the 16th century following Roman Imperial examples such as the Arch of Titus in Rome. It 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 architec ...

Column
A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. The term ''column'' applies especially to a large round support (the shaft of the column) with a capital and a base or pedestal, which is made of stone, or appearing to be so. A small wooden or metal support is typically called a '' post''. Supports with a rectangular or other non-round section are usually called '' piers''. For the purpose of wind or earthquake engineering, columns may be designed to resist lateral forces. Other compression members are often termed "columns" because of the similar stress conditions. Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest. In architecture, "column" refers to such a structural element that also has certain proportional and decorative f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lintel
A lintel or lintol is a type of beam (a horizontal structural element) that spans openings such as portals, doors, windows and fireplaces. It can be a decorative architectural element, or a combined ornamented/structural item. In the case of windows, the bottom span is referred to as a sill, but, unlike a lintel, does not serve to bear a load to ensure the integrity of the wall. Modern-day lintels may be made using prestressed concrete and are also referred to as beams in beam-and-block slabs or as ribs in rib-and-block slabs. These prestressed concrete lintels and blocks can serve as components that are packed together and propped to form a suspended-floor concrete slab. An arch functions as a curved lintel. Structural uses In worldwide architecture of different eras and many cultures, a lintel has been an element of post and lintel construction. Many different building materials have been used for lintels. In classical Western architecture and construction methods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niche (architecture)
In architecture, a niche (Canadian English, CanE, or ) is a recess or cavity constructed in the thickness of a wall for the reception of decorative objects such as statues, busts, urns, and vases. In Classical architecture examples are an exedra or an apse that has been reduced in size, retaining the half-dome heading usual for an apse. In the first century B.C, there was no exact mention of niches, but rather a zotheca or small room. These rooms closely resemble alcoves similar to a niche but slightly larger. Different sizes and sculpture methods suggest the term niche was understood. Greeks and Romans especially, used niches for important family tombs. Etymology The word derives from the Latin (), via the French . The Italian ''Contrade of Siena#Nicchio (Seashell), nicchio'' () may also be involved in the origin of the word, as the traditional decoration for the top of a niche is a scallop shell, hence also the alternative term of semi-dome, "conch" for a semi-dome, usually ...

Apse
In architecture, an apse (: apses; from Latin , 'arch, vault'; from Ancient Greek , , 'arch'; sometimes written apsis; : apsides) is a semicircular recess covered with a hemispherical Vault (architecture), vault or semi-dome, also known as an ''exedra''. In Byzantine architecture, Byzantine, Romanesque architecture, Romanesque, and Gothic architecture, Gothic Architecture of cathedrals and great churches, Christian church architecture, 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 and west, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay (architecture)
In architecture, a bay is the space between architectural elements, or a recess or compartment. The term ''bay'' comes from Old French ''baie'', meaning an opening or hole."Bay" ''Online Etymology Dictionary''. http://www.etymonline.com/index.php?allowed_in_frame=0&search=bay&searchmode=none accessed 3/10/2014 __NOTOC__ Examples # The spaces between post (structural), posts, columns, or buttresses in the length of a building, the division in the widths being called aisle, aisles. This meaning also applies to overhead vaults (between rib vault, ribs), in a building using a vaulted structural system.

Octagon
In geometry, an octagon () is an eight-sided polygon or 8-gon. A '' regular octagon'' has Schläfli symbol and can also be constructed as a quasiregular truncated square, t, which alternates two types of edges. A truncated octagon, t is a hexadecagon, . A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square. Properties The sum of all the internal angles of any octagon is 1080°. As with all polygons, the external angles total 360°. If squares are constructed all internally or all externally on the sides of an octagon, then the midpoints of the segments connecting the centers of opposite squares form a quadrilateral that is both equidiagonal and orthodiagonal (that is, whose diagonals are equal in length and at right angles to each other).Dao Thanh Oai (2015), "Equilateral triangles and Kiepert perspectors in complex numbers", ''Forum Geometricorum'' 15, ...

Quatrefoil
A quatrefoil (anciently caterfoil) is a decorative element consisting of a symmetrical shape which forms the overall outline of four partially overlapping circles of the same diameter. It is found in art, architecture, heraldry and traditional Christian symbolism. The word 'quatrefoil' means "four leaves", from the Latin , "four", plus , "leaf"; the term refers specifically to a four-leafed clover, but applies in general to four-lobed shapes in various contexts. In recent years, several luxury brands have attempted to fraudulently assert creative rights related to the symbol, which naturally predates any of those brands' creative development. A similar shape with three rings is called a trefoil, while a shape with five is a cinquefoil. History The quatrefoil enjoyed its peak popularity during the Gothic architecture, Gothic and Renaissance eras. It is most commonly found as tracery, mainly in Gothic architecture, where a quatrefoil often may be seen at the top of a Gothic arch, ...

Cupola
In architecture, a cupola () is a relatively small, usually dome-like structure on top of a building often crowning a larger roof or dome. Cupolas often serve as a roof lantern to admit light and air or as a lookout. The word derives, via Italian language, Italian, from lower Latin ''cupula'' (classical Latin ''cupella''), (Latin ''cupa''), indicating a vault resembling an upside-down cup. The cylindrical drum underneath a larger cupola is called a tholobate. Background The cupola evolved during the Renaissance from the older Oculus (architecture), oculus. Being weatherproof, the cupola was better suited to the wetter climates of northern Europe. The chhatri, seen in Architecture of India, Indian architecture, fits the definition of a cupola when it is used atop a larger structure. Cupolas often serve as a Bell tower, belfry, Belvedere (structure), belvedere, or roof lantern above a main roof. In other cases they may crown a spire, tower, or Turret (architecture), turret. B ...
