A dome (from Latin: domus) 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 wall, a 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. A dome's apex may be closed or may be open in the form of an 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, Hellenistic, Roman, and Chinese architecture in the ancient world, as well as among a number of indigenous building traditions throughout the world. Dome structures were common in both Byzantine architecture and Sasanian architecture, which influenced that of the rest of Europe and Islam, respectively, in the Middle Ages. The domes of European Renaissance architecture spread from Italy in the early modern period, while domes were frequently employed in Ottoman architecture at the same time. Baroque and Neoclassical architecture took inspiration from Roman domes.
Advancements in mathematics, materials, and production techniques resulted in new dome types. Domes have been constructed over the centuries from mud, snow, stone, wood, brick, concrete, metal, glass, and plastic. The symbolism associated with domes includes mortuary, celestial, and governmental traditions that have likewise altered over time. The domes of the modern world can be found over religious buildings, legislative chambers, sports stadiums, and a variety of functional structure
EASTERN ORTHODOX ARCHITECTURE
constitutes a distinct, recognizable family of styles among church architectures. These styles share a cluster of fundamental similarities, having been influenced by the common legacy of Byzantine architecture from the Eastern Roman Empire. Some of the styles have become associated with the particular traditions of one specific autocephalous Orthodox patriarchate, whereas others are more widely used within the Eastern Orthodox Church.
These architectural styles have held substantial influence over cultures outside Eastern Orthodoxy; particularly in the architecture of Islamic mosques,[1] but also to some degree in Western churches.
While sharing many traditions, Eastern Christianity and Western Christianity began to diverge from each other from an early date. Whereas the basilica, a long aisled hall with an apse at one end, was the most common form in the West, a more compact centralised style became predominant in the East.
These churches were in origin "martyria" focused on the tombs of the saints—specifically, the martyrs who had died during the persecutions, which only fully ended with the conversion of the Emperor Constantine. They copied pagan tombs and were roofed over by a dome which symbolised heaven. The central dome was then often surrounded by structures at the four points of the compass producing a cruciform shape - these were themselves often topped by towers or domes. The centralised and basilica structures were sometimes combined as in the church of Hagia Sophia in Constantinople. The basilican east end then allowed for the erection of an iconostasis, a screen on which icons are hung and which conceals the altar from the worshippers except at those points in the liturgy when its doors are opened.
