Two-centred Arch
A pointed arch, ogival arch, or Gothic arch is an arch with a pointed crown meet at an angle at the top of the arch. Also known as a two-centred arch, its form is derived from the intersection of two circles. This architectural element was particularly important in Gothic architecture. The earliest use of a pointed arch dates back to bronze-age Nippur. As a structural feature, it was first used in eastern Christian architecture, Byzantine architecture and Sasanian architecture, but in the 12th century it came into use in France and England as an important structural element, in combination with other elements, such as the rib vault and later the flying buttress. These allowed the construction of cathedrals, palaces and other buildings with dramatically greater height and larger windows which filled them with light. Early arches Crude arches pointed in shape have been discovered from the Bronze Age site of Nippur dated earlier than 2700 BC. The palace of Nineveh also has poin ...

Persian Architecture
Iranian architecture or Persian architecture (, ''Me'māri e Irāni'') is the architecture of Iran and parts of the rest of West Asia, the Caucasus and Central Asia. Its history dates back to at least 5,000 BC with characteristic examples distributed over a vast area from Turkey and Iraq to Uzbekistan and Tajikistan. Persian buildings vary greatly in scale and function, from vernacular architecture to monumental complexes. In addition to historic gates, palaces, and mosques, the rapid growth of cities such as the capital Tehran has brought about a wave of demolition and new construction. According to American historian and archaeologist Arthur Upham Pope, Arthur Pope, the supreme Iranian art, in the proper meaning of the word, has always been its architecture. The supremacy of architecture applies to both pre- and post-Islamic periods. Iranian architecture displays great variety, both structural and aesthetic, from a variety of traditions and experience. Without sudden innovatio ...

Persianate
A Persianate society is a society that is based on or strongly influenced by the Persian language, culture, literature, art and/or identity. The term "Persianate" is a neologism credited to Marshall Hodgson. In his 1974 book, ''The Venture of Islam: The expansion of Islam in the Middle Periods'', he defined it thus: "The rise of Persian had more than purely literary consequences: it served to carry a new overall cultural orientation within Islamdom.... Most of the more local languages of high culture that later emerged among Muslims... depended upon Persian wholly or in part for their prime literary inspiration. We may call all these cultural traditions, carried in Persian or reflecting Persian inspiration, 'Persianate' by extension."Hodgson says, "It could even be said that Islamicate civilization, historically, is divisible in the more central areas into an earlier 'caliphal' and a later 'Persianate' phase; with variants in the outlying regions—Maghrib, Sudanic lands, Souther ...

Fatimid Architecture
The Fatimid architecture that developed in the Fatimid Caliphate (909–1167 CE) of North Africa combined elements of eastern and western architecture, drawing on Abbasid architecture, Byzantine, Ancient Egyptian, Coptic architecture and North African traditions; it bridged early Islamic styles and the medieval architecture of the Mamluks of Egypt, introducing many innovations. The wealth of Fatimid architecture was found in the main cities of Mahdia (921–948), Al-Mansuriya (948–973) and Cairo (973–1169). The heartland of architectural activity and expression during Fatimid rule was at al-Qahira (Cairo), on the eastern side of the Nile, where many of the palaces, mosques and other buildings were built. Large-scale constructions were undertaken during the reigns of al-Mui'zz () Al-Aziz Billah () and al-Hakim (). The Fatimid caliphs competed with the rulers of the Abbasid and Byzantine empires and indulged in luxurious palace building. Their palaces, their greate ...

Abbasids
The Abbasid Caliphate or Abbasid Empire (; ) was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. After overthrowing the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132  AH), they ruled as caliphs based in modern-day Iraq, with Baghdad being their capital for most of their history. The Abbasid Revolution had its origins and first successes in the easterly region of Khurasan, far from the Levantine center of Umayyad influence. The Abbasid Caliphate first centered its government in Kufa, modern-day Iraq, but in 762 the caliph al-Mansur founded the city of Baghdad as the new capital. Baghdad became the center of science, culture, arts, and invention in what became known as the Golden Age of Islam. By housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-rel ...

Four-centred Arch
A four-centred arch (Commonwealth spelling) or four-centered arch (American spelling) is a low, wide type of arch with a pointed apex. Its structure is achieved by drafting two arcs which rise steeply from each springing point on a small radius, and then turning into two arches with a wide radius and much lower springing point. It is a pointed sub-type of the general flattened depressed arch. This type of arch uses space efficiently and decoratively when used for doorways. It is also employed as a wall decoration in which arcade and window openings form part of the whole decorative surface. Two of the most notable types are known as the Persian arch, which is moderately "depressed" and found in Islamic architecture, and the Tudor arch, which is much flatter and found in English architecture. Another variant, the keel arch, has partially straight rather than curved sides and developed in Fatimid architecture. Use in Islamic architecture The four-centered arch is widely used ...

Abbasid Architecture
Abbasid architecture developed in the Abbasid Caliphate (750 to 1258 CE), primarily in its heartland of Mesopotamia (Iraq). The great changes of the Abbasid era can be characterized as at the same time political, geo-political and cultural. The Abbasid period starts with the destruction of the Umayyad dynasty, Umayyad ruling family and its replacement by the Abbasid dynasty, Abbasids, and the position of power is shifted to the Mesopotamian area. As a result there was a corresponding displacement of the influence of Classical architecture, classical and Byzantine architecture, Byzantine artistic and cultural standards in favor of local Architecture of Mesopotamia, Mesopotamian models as well as Iranian architecture, Persian. The Abbasids evolved distinctive styles of their own, particularly in decoration. This occurred mainly during the period corresponding with their power and prosperity between 750 and 932. Abbasid architecture was an important formative stage in wider Islamic a ...

Umayyad Architecture
Umayyad architecture developed in the Umayyad Caliphate between 661 and 750, primarily in its heartlands of Syria and Palestine. It drew extensively on the architecture of older Middle Eastern and Mediterranean civilizations including the Sassanian Empire and especially the Byzantine Empire, but introduced innovations in decoration and form. Under Umayyad patronage, Islamic architecture began to mature and acquire traditions of its own, such as the introduction of mihrabs to mosques, a trend towards aniconism in decoration, and a greater sense of scale and monumentality compared to previous Islamic buildings. The most important examples of Umayyad architecture are concentrated in the capital of Damascus and the Greater Syria region, including the Dome of the Rock, the Great Mosque of Damascus, and secular buildings such as the Mshatta Palace and Qusayr 'Amra. Historical background The Umayyad Caliphate was established in 661 after Ali, the son-in-law of Muhammad, was murdered ...
