OTTOMAN ARCHITECTURE SINAN

WORK

Mid-1550s to 1570: qualification stage

By 1550, Sultan Süleyman the Magnificent was at the height of his powers. Having built a mosque for his son, he felt it was time to construct his own imperial mosque, an enduring monument larger than all the others, to be built on a gently sloping hillside dominating the Golden Horn. Money was no problem, since he had accumulated a treasure from the loot of his campaigns in Europe and the Middle East. He gave the order to his royal architect Sinan to build a mosque, the Süleymaniye, surrounded by a külliye consisting of four colleges, a soup kitchen, a hospital, an asylum, a hamam, a caravanserai and a hospice for travellers (tabhane). Sinan, now heading a formidable department with a great number of assistants, finished this formidable task in seven years.

Before Süleymaniye, no mosques had been built with half cubic roofs. He got the idea of half cubic roof design from the Hagia Sophia. Through this monumental[according to whom?] achievement, Sinan emerged from the anonymity of his predecessors. Sinan must have known the ideas of the Renaissance architect Leone Battista Alberti (who in turn had studied De architectura by the Roman architect and engineer Vitruvius), since he too was concerned in building the ideal church, reflecting harmony through the perfection of geometry in architecture. But, contrary to his Western counterparts, Sinan was more interested in simplification than in enrichment. He tried to achieve the largest volume under a single central dome. The dome is based on the circle, the perfect geometrical figure representing, in an abstract way, a perfect God. Sinan used subtle geometric relationships, using multiples of two when calculating the ratios and the proportions of his buildings. However, in a later stage, he also used divisions of three or ratios of two to three when working out the width and the proportions of domes, such as the Sokollu Mehmet Pasha Mosque at Kadırga.

While he was fully occupied with the construction of the Süleymaniye, Sinan or his subordinates drew up the plans and gave instructions for many other constructions. But it is highly improbable that he personally supervised the construction of the provincial assignments.
Sinan built a mosque for the Grand Vizier Ibrahim Pasha and a funeral monument (türbe) at Silivrikapı (Constantinople) in 1551.
The next Grand Vizier Rüstem Pasha gave Sinan several more commissions. In 1550, Sinan built a large inn (han) in the Galata district of Istanbul. About ten years later he built another han in Edirne, and between 1544 and 1561 the Taṣ Han at Erzurum. He designed a caravanserai in Eregli[disambiguation needed] and an octagonal madrasah in Constantinople.

Between 1553 and 1555, Sinan built the Sinan Pasha Mosque at Beşiktaş, a smaller version of the Üç Şerefeli Mosque at Edirne, for the Grand Admiral Sinan Pasha. This proves again that Sinan had thoroughly studied the work of other architects, especially since he was responsible for the upkeep of these buildings. He copied the old form, pondered over the weaknesses in the construction and tried to solve this with his own solution. In 1554, Sinan used the form of the Sinan Pasha mosque again for the construction of the mosque for the next Grand Vizier Kara Ahmet Pasha in Constantinople, his first hexagonal mosque. By applying this hexagonal form, Sinan could reduce the side domes to half-domes and set them in the corners at an angle of 45 degrees. Clearly, Sinan must have appreciated this form,[citation needed] since he repeated it later in mosques such as the Sokollu Mehmed Pasha Mosque at Kadırga and the Atik Valide Mosque at Üsküdar.

In 1556, Sinan built the Haseki Hürrem Hamam, replacing the antique Baths of Zeuxippus which are still standing close to the Hagia Sophia. This would become one of the most beautiful hamams he ever constructed.

In 1559, he built the Cafer Ağa madrasah below the forecourt of the Hagia Sophia. In the same year he began the construction of a small mosque for Iskender Pasha at Kanlıka, beside the Bosphorus. This was one of the many minor and routine commissions the office of Sinan received over the years.

In 1561, when Rüstem Pasha died, Sinan began the construction of the Rüstem Pasha Mosque, as a memorial supervised by his widow Mihrimah Sultana. It is situated just below the Süleymaniye. This time the central form is octagonal, modelled on the monastery church of Saints Sergius and Bacchus, with four small semi-domes set in the corners. In the same year, Sinan built a funeral monument (türbe) for Rüstem Pasha in the garden of the Şehzade Mosque, decorated with the finest tiles Iznik could produce. Mihrimah Sultana, having doubled her wealth after the death of her husband, now wanted a mosque of her own. Sinan built for her the Mihrimah Camii at Edirnekapı (Edirne Gate), on the highest of the seven hills of Constantinople. He raised the mosque on a vaulted platform, accentuating its hilltop site. There is some speculation concerning the dates; until recently this was supposed to be between 1540 and 1540, but now it is generally accepted to be between 1562 and 1565. Sinan, concerned with grandeur, built a mosque in one of his most imaginative designs, using new support systems and lateral spaces to increase the area available for windows. He built a central dome of 37 m high and 20 m wide, supported by pendentives, on a square base with two lateral galleries, each with three cupolas. At each corner of this square stands a gigantic pier, connected with immense arches each with 15 large windows and four circular ones, flooding the interior with light. The style of this revolutionary building was as close to the Gothic style as Ottoman structure permits

Between 1560 and 1566 Sinan built a mosque in Constantinople for Zal Mahmud Pasha on a hillside beyond Ayvansaray. Sinan certainly conceived the plans and partly supervised the construction, but left the building of lesser areas to less than competent hands, since Sinan and his most able assistants were about to begin his masterpiece, the Selimiye Mosque in Edirne. On the outside, the mosque rises high, with its east wall pierced by four tiers of windows. This gives the mosque an aspect of a palace or even a block of apartments. Inside, there are three broad galleries making the interior look compact. The heaviness of this structure makes the dome look unexpectedly lofty. These galleries look like a preliminary try-out for the galleries of the Selimiye Mosque.



The period from 1570 to his death: master stage

In this late stage of his life, Sinan tried to create unified and sublimely elegant interiors. To achieve this, he eliminated all the unnecessary subsidiary spaces beyond the supporting piers of the central dome. This can be seen in the Sokollu Mehmet Paşa mosque in Istanbul (1571–1572) and in the Selimiye mosque in Edirne. In other buildings of his final period, Sinan experimented with spatial and mural treatments that were new in the classical Ottoman architecture.

According to him from his autobiography "Tezkiretü’l Bünyan", his masterpiece is the Selimiye Mosque in Edirne. Breaking free of the handicaps of traditional Ottoman architecture, this mosque marks the climax of Sinan's work and of all classical Ottoman architecture. While it was being built, the architect's saying of "You can never build a dome larger than the dome of Hagia Sophia and specially as Muslims" was his main motivation. When it was completed, Sinan claimed that it had the largest dome in the world, leaving Hagia Sophia behind. In fact, the dome height from the ground level was lower and the diameter barely larger (0.5 meters, approximately 2 feet) than the millennium-older Hagia Sophia. However, measured from its base the dome of Selimiye is higher. Sinan was more than 80 years old when the building was finished. In this mosque he finally realized his aim of creating the optimum, completely unified, domed interior : a triumph of space that dominates the interior. He used this time an octagonal central dome (31.28 m wide and 42 m high), supported by eight elephantine piers of marble and granite. These supports lack any capitals but have squinches or consoles at their summit, leading to the optical effect that the arches seem to grow integrally out of the piers. By placing the lateral galleries far away, he increased the three-dimensional effect. The many windows in the screen walls flood the interior with light. The buttressing semi-domes are set in the four corners of the square under the dome. The weight and the internal tensions are hidden, producing an airy and elegant effect rarely seen under a central dome. The four minarets (83 m high) at the corners of the prayer hall are the tallest in the Muslim world, accentuating the vertical posture of this mosque that already dominates the city.

He also designed the Taqiyya al-Sulaimaniyya khan and mosque in Damascus, still considered one of the city's most notable monuments, as well as the Banya Bashi Mosque in Sofia, Bulgaria, currently the only functioning mosque in the city. He has also built Mehmed Paša Sokolović Bridge in Višegrad across the Drina River in the east of Bosnia and Herzegovina which is now UNESCO World Heritage Site.
