Hagia Sophia
built 645 days ago
Hagia Sophia or Holy Wisdom is the mother church of all Eastern Christians of the Byzantine liturgical tradition both Orthodox and Greek Catholic. Early accounts suggest that the site of this, the grandest church in Christendom, in the first millennium had been the site of a pagan temple appropriated for the service of the new religion. The first church on the site was built by the Eastern Roman Emperor Constantius, son of Emperor Constantine, who had liberated the Christian faith from centuries of persecution. Constantius' church was consecrated in 360 AD. At first it was known as the Great Church because it was the largest at the time. Later it became known as Holy Wisdom, a name attributed to Christ by theologians of the 4th century.

Hagia Sophia was the seat of the Orthodox patriarch of Constantinople and a principal setting for imperial ceremonies. During the Latin Occupation (1204-1261) the church became a Roman Catholic cathedral, and its many treasures and relics were dispersed. It was converted to a mosque after the Fall of Constantinople to the Ottoman Turks under Sultan Mehmed II in 1453. Since more conservative factions of Islam consider the depiction of the human form to be blasphemous, its mosaics were covered with plaster. One must note... that due to the foresightedness and tolerance of the Ottoman Sultans, the plaster was periodically removed, the mosaics maintained, and replastered. For almost 500 years the principal mosque of Istanbul, Ayasofya served as model for many of the Ottoman mosques such as the Shehzade Mosque, the Suleiman Mosque, and the Rüstem Pasha Mosque.

The Hagia Sophia has four minarets at its corners that were added at different times. The brick minaret at the southern corner is attributed to Mehmed II, and a second stone minaret was added to the north by Mimar Sinan during his restoration. The remaining two minarets are identical and date from the Murad III period.

Although this design stabilizes the dome and the surrounding walls and arches, the actual construction of the walls of Hagia Sophia weakened the overall structure. The bricklayers used more mortar than brick, which weakened the walls. The structure would have been more stable if the builders at least let the mortar cure before they began the next layer; ... they did not do this. When the dome was placed atop the building, the weight of the dome caused the walls to lean outward because of the wet mortar underneath. When Isidorus the Younger rebuilt the original dome, he had to first build up the interior of the walls so that they were vertical in order to support the weight of the new dome. Another probable change in the design of the dome when it was rebuilt was the actual height of the dome.

Construction for Hagia Sophia, the Church of Holy Wisdom, started in 532. Amazingly, it took only five years to complete. It replaced two previous versions of the church that had been destroyed. For more than a thousand years, Hagia Sophia was the largest and grandest church in the world. When Sultan Mehmet II converted it into a mosque, the loss devastated Orthodox Christians. Ironically, Hagia Sophia’s design impressed the Ottomans so much that it was copied in other mosques throughout the empire.

The most famous restoration of the Hagia Sophia was ordered by Sultan Abdülmecid and completed by eight hundred workers between 1847 and 1849, under the supervision of the Swiss-Italian architect brothers Gaspare and Giuseppe Fossati. The brothers consolidated the dome and vaults, straightened the columns, and revised the decoration of the exterior and the interior of the building. The mosaics in the upper gallery were cleaned. The old chandeliers were replaced by new pendant ones. New gigantic circular-framed disks were hung on columns. They were inscribed with the names of Allah, the prophet Muhammad, the first four caliphs Abu Bakr, Umar, Uthman and Ali, and the two grandchildren of Mohammed: Hassan and Hussain, by the calligrapher Kazasker İzzed Effendi (1801-1877).
