Armenian influence

The pointed arch, one of the defining attributes of Gothic, was earlier featured in Islamic architecture, Though it did not have the same functions. Precursor of pointed arch appeared in Byzantine and Sassanian architectures, This was evidenced in early church building in Syria and occasional secular structures, like the Karamagara Bridge; in Sassanian architecture, employed in palace and sacred construction. These pre-Islamic arches were decorative rather than structural in their function. The pointed arch as an architectonic principle was first clearly established in Islamic architecture; as an architectonic principle, the pointed arch was entirely alien to the pre-Islamic world. Use of the pointed arch seems to have taken off dramatically in Islamic architecture. It begins to appear throughout the Islamic world in close succession after its adoption in the late Umayyad or early Abbasid period. Some examples are the Al-Ukhaidir Palace (775 AD), the Abbasid reconstruction of the Al-Aqsa mosque in 780 AD, the Ramlah Cisterns (789 AD), the Great Mosque of Samarra (851 AD), and the Mosque of Ibn Tulun (879 AD) in Cairo. It also appears in one of the early reconstructions of the Great Mosque of Kairouan in Tunisia, and the Mosque–Cathedral of Córdoba in 987 AD. The pointed arch had already been used in Syria, but in the mosque of Ibn Tulun we have one of the earliest examples of its use on an extensive scale, some centuries before it was exploited in the West by the Gothic architects.

A kind of rib vault was also used in Islamic architecture, for example in the ceiling of the Mosque-Cathedral of Cordoba. In Cordoba, the dome was supported by pendentives, which connected the dome to the arches below. The pendentives were decorated with ribs. Unlike the Gothic rib vault, the Islamic ribs were purely decorative; they did not extend outside of the vault, and they were not part of the structure supporting the roof.

The military and cultural contacts with the medieval Islamic world, including the Norman conquest of Islamic Sicily in 1090, the Crusades (beginning 1096), and the Islamic presence in Spain, may have influenced Medieval Europe 's adoption of the pointed arch. Another feature of Gothic architecture, a kind of rib vault, had also earlier appeared in Islamic architecture, and spread to Western Europe via Islamic Spain and Sicily. The early rib vaults in Spain were used to support cupolas, and were decorative. The dome of the Mosque-Cathedral of Cordoba was supported by pendentives, rather than the vault. These were frequently used in Romanesque and Byzantine architecture, as in the dome of Hagia Sophia in Istanbul, which also was supported by pendentives. The Gothic rib vault, among other features, such as the flying buttress, have their antecedents in Romanesque architecture, such as Durham Cathedral, constructed between 1093 and 1096.

In those parts of the Western Mediterranean subject to Islamic control or influence, rich regional variants arose, fusing Romanesque and later Gothic traditions with Islamic decorative forms. For example, in Monreale and Cefalù Cathedrals, the Alcázar of Seville, and Teruel Cathedral.

A number of scholars have cited the Armenian Cathedral of Ani, completed 1001 or 1010, as a possible influence on the Gothic, especially due to its use of pointed arches and cluster piers. However, other scholars such as Sirarpie Der Nersessian, who rejected this notion as she argued that the pointed arches did not serve the same function of supporting the vault. Lucy Der Manuelian contends that some Armenians (historically documented as being in Western Europe in the Middle Ages) could have brought the knowledge and technique employed at Ani to the west. --->
