Classes In Medieval Islamic Persia Little evidence survives to show how a new social order replaced the old Sasanian class system during the early Islamic era. A new social stratification and conception of inequality seems to have gradually emerged under the influence of:
The Great Mosque of Kairouanwith a large courtyard sehan surrounded by arcadesKairouanTunisia. The traditional Islamic courtyarda sehan Arabic: When within a residence or other secular building is a private courtyard and walled garden.
It is used for: A sehan—courtyard is in within almost every mosque in Islamic architecture. The courtyards are open to the sky and surrounded on all sides by structures with halls and rooms, and often a shaded semi-open arcade. Sehans usually feature a centrally positioned ritual cleansing pool under an open domed pavilion called a howz.
Hypostyle hall[ edit ] A Hypostylei. The Roman type of building has developed out of the Greek agora. In Islamic architecture, the hypostyle hall is the main feature of the hypostyle mosque.
One of the earliest hypostyle mosques is the Tarikhaneh Mosque in Iran, dating back to the 8th century.
Whilst Umayyad architecture continues Syrian traditions of the 6th and 7th century, Eastern Islamic architecture was mainly influenced by Sasanian styles and forms. Diaphragm arches with lintelled ceilings made of wood or stone beams, or, alternatively, with barrel vaults, were known in the Levant since the classical and Nabatean period.
They were mainly used to cover houses and cisterns. The architectural form of covering diaphragm arches with barrel vaults, however, was likely newly introduced from Iranian architectureas similar vaulting was not known in Bilad al-Sham before the arrival of the Umayyads.
The earliest known example for barrel vaults resting on diaphragm arches from Umayyad architecture is known from Qasr Harane in Syria. During the early period, the diaphragm arches are built from coarsely cut limestone slabs, without using supporting falseworkwhich were connected by gypsum mortar.
Later-period vaults were erected using pre-formed lateral ribs modelled from gypsum, which served as a temporal formwork to guide and center the vault. These ribs, which were left in the structure afterwards, do not carry any load.
The ribs were cast in advance on strips of cloth, the impression of which can still be seen in the ribs today. Similar structures are known from Sasanian architecturefor example from the palace of Firuzabad.
Umayyad-period vaults of this type were found in Amman Citadel and in Qasr Amra. Columns are connected by horseshoe archesand support pillars of brickworkwhich are in turn interconnected by semicircular arches supporting the flat timberwork ceiling. Horseshoe arches were now used for the upper row of arcades, which is now supported by five-pass arches.
In sections which now supported domesadditional supporting structures were needed to bear the thrust of the cupolas.
The architects solved this problem by the construction of intersecting three- or five-pass arches. The three domes spanning the vaults above the mihrab wall are constructed as ribbed vaults.
Rather than meeting in the center of the dome, the ribs intersect one another off-center, forming an eight-pointed star in the center which is superseded by a pendentive dome.
Mosque of Cristo de la Luz in Toledo was constructed with a similar, eight-ribbed dome. The architectural form of the ribbed dome was further developed in the Maghreb: The central dome of the Great Mosque of Tlemcena masterpiece of the Almoravids built inhas twelve slender ribs, the shell between the ribs is filled with filigree stucco work.
The "non-radial rib vault", an architectural form of ribbed vaults with a superimposed spherical dome, is the characteristic architectural vault form of the Islamic East. From its beginnings in the Jameh Mosque of Isfahan, this form of vault was used in a sequence of important buildings up to the period of Safavid architecture.
Its main characteristics are: Wide central domes with huge diameters were erected on top of a centre-plan building. Despite their enormous weight, the domes appear virtually weightless. Some of the most elaborate domed buildings have been constructed by the Ottoman architect Mimar Sinan.
When the Ottomans had conquered Constantinoplethey found a variety of Byzantine Christian churches, the largest and most prominent amongst them was the Hagia Sophia. The brickwork-and-mortar ribs and the spherical shell of the central dome of the Hagia Sophia were built simultaneously, as a self-supporting structure without any wooden centring.
Shell and ribs form one single structural entity. Zeyrek Mosquethe central medallion of the apex and the ribs of the dome became separate structural elements: The ribs are more pronounced and connect to the central medallion, which also stands out more pronouncedly, so that the entire construction gives the impression as if ribs and medallion are separate from, and underpin, the proper shell of the dome.Islamic architecture thus is directly related to Persian and Byzantine architecture.
In Persia and Central Asia, the Tahirids, Samanids, Ghaznavids, and Ghurids struggled for power in the 10th century, and art was a vital element of this competition. Significant for the time was the Persian Achaemenid Empire.
