'oca Mi‘mār Sinān Āġā' (Ottoman Turkish: خوجه معمار سنان آغا) (April 15, 1489 - July 17, 1588) was the chief Ottoman architect for sultans Selim I, Suleiman I, Selim II and Murad III. He was, during a period of fifty years, responsible for the construction or the supervision of every major building in the Ottoman Empire. More than three hundred buildings are listed to his name, not including smaller ones such as Koran schools (''sibyan mektebs''). His masterpiece is the Selimiye Mosque in Edirne, although his most famous work is the Suleiman Mosque in Istanbul. He had under him a large government department and trained many assistants, who, in turn, distinguished themselves, such as Sedefhar Mehmet Ağa, the builder of the Sultan Ahmed Mosque. He is considered the greatest architect of the classical period, compared to his Western contemporary Michelangelo. The stature of Michelangelo and his plans for the St Peter's Basilica in Rome were well-known in Istanbul, since he (and also Leonardo da Vinci) received an invitation to build a bridge over the Bosphorus ^[1]
Sinan was also one of the first earthquake engineers in the world.

Background

Much of his origin is shrouded in myth. However there are three brief records in the library of the Topkapı Palace, dictated by Sinan to his friend Mustafa Sâi. (Anonymous Text; Architectural Masterpieces; Book of Architecture). In these manuscripts, Sinan divulges some details of his youth and military career. According to these documents Sinan was the son of Abdülmenan (the anonym of Christian fathers whose sons were Moslem converts), but this name is als given as Aptullah, Abdullah and Hristo.
Sinan was born a Christian in Anatolia in a small town called Ağırnas (present name Mimarsinanköy) near the city of Kayseri (as stated in an order of sultan Selim II), probably of Greek^{[2][3][4] [5]} origin. Later, he was sometimes called Kayserli Sinan (referring to his hometown), before receiving the tile of ''Koca'' (elder).
In 1512, he was conscripted into Ottoman service (''devṣirme levy''). He went to Istanbul as a recruit to the Janissary Corps, and was circumcised as he was converted to Islam under the devshirme system. Since he was over twenty-one years old, he was not admitted to the Imperial Enderun College in the Topkapı Palace but was sent instead to an auxiliary school. He served the Grand Vizier İbrahim Paşa as a novice of the Ibrahim Pasha School (but this is far from being proven). There he was given the Islamic name Sinan. He initially learned carpentry and mathematics. But through his intellectual qualities and ambitions, he soon assisted the leading architects and got his training as an architect.
Three years later he was a skilled architect and engineer. During this time he was also trained as a cadet (''acemioğlan'') over six years before being admitted to the brotherhood of Janissaries. This must have been prior to 1520, when he took part in Selim's military campaigns into Rhodes as part of the engineering corps. Two years later he also witnessed the conquest of Belgrade.
He was present, as a member of the Household Cavalry, in the Battle of Mohács, led by the new sultan Suleiman the Magnificent. He was promoted a captain in the Royal Guard and then given command of the Infantry Cadet Corps. He was later stationed in Austria, where he commanded the 62nd Orta of the Rifle Corps. He became a master of archery, while at the same time, as an architect, learning the weak points of structures when gunning them down. In 1535 he participated in the Baghdad campaign as a commanding officer of the Royal Guard. In 1537 he went on expedition to Corfu and Apulia and finally to Moldavia.
During all these campaigns he had proven to be a trained engineer and an able architect. When the Ottoman army captured Cairo, Sinan was promoted to chief architect and was given the privilege of tearing down any buildings in the captured city that were not according to the city plan. During the campaign in the East, he assisted in the building of defences and bridges, such as a bridge across the Danube. He converted churches into mosques. During the Persian campaign in 1535 he built ships for the army and the artillery to cross Lake Van. For this he was given the title ''Haseki'i'', Sergeant-at-Arms in the body guard of the Sultan, a rank equivalent to that of the Janissary Ağa.
When Çelebi Lütfi Pasha became Grand Vizier in 1539, he appointed Sinan, who had previously served under his command, Architect of the Abode of Felicity (another name for Istanbul). This was the start of a remarkable career. It was his task to supervise the constructions and the flow of supplies within the Ottoman empire. he was also responsible for the design and construction of public works, such as roads, waterworks and bridges. Through the years he transformed his office into that of Architect of the Empire, an elaborate government department, with greater powers than his supervising minister. He became the head of a whole Corps of Court Architects, training a team of assistants, deputies and pupils.

Work

His training as an army engineer gave Sinan rather an empirical approach to architecture than a theoretical one. But the same can be said of the great Western Renaissance architects, such as Brunelleschi and Michelangelo.
At the start of Sinan's career, Ottoman architecture was highly pragmatical. Buildings were repetitions of former types and were based on rudimentary plans. They were more an assembly of parts than a conception of a whole. An architect could sketch a plan for a new building and an assistant or foreman knew what to do, because novel ideas where avoided. Moreover, architects used an extravagant margin of safety in their designs, resulting in a wasteful use of material and labour. Sinan would gradually change all this. He was to transform established architectural practices, amplifying and transforming the traditions by adding innovations, trying to approach perfection.
The major works of Sinan can be divided roughly into three periods :

The early years (till the mid-1550s) : apprenticeship period

During these years he continued the traditional pattern of Ottoman architecture. But he gradually began exploring other possibilities, because, during his military career, he had the opportunity to study the architectural monuments in the conquered cities of Europe and the Middle East.
His first attempt to build an important monument was the Hüsrev Pasha mosque and its double medresse in Aleppo, Syria. It was built in the winter 1536-1537 between two army campaigns for his commander-in-chief and the governor of Aleppo. It was built in haste and it shows in the coarseness of execution and the crude decoration.

His first major commission as the royal architect was the construction of a modest Haseki Hürrem complex for Roxelana, the wife of sultan Süleyman the Magnificent. He had to follow the plans drawn by his predecessors. Sinan retained the traditional arrangement of the available space without any innovations. Nevertheless it is already better built than the Aleppo mosque and it shows a certain elegance. But it has suffered from many restorations.
He started in 1541 the construction of the mausoleum (''türbe'') of the Grand Admiral Hayreddin Barbarossa. It stands by the shore of Beṣiktaṣ on the European part of Istanbul, at the site where his fleet used to assemble. Oddly enough, the admiral is not buried there, but in his türbe next to the Iskele mosque. This mausoleum has been severely neglected since.
Mihrimah Sultana, the only daughter of Süleyman and wife of the Grand Vizier Rüstem Pasha gave Sinan the commission to build a mosque with ''medrese'' (college), an ''imaret'' (soup kitchen) and a ''sibyan mekteb'' (Koran school) in Üsküdar. The ''imaret'' no longer exists. This Iskele Mosque (or Jetty mosque) already shows several hallmarks of Sinan's mature style : a spacious,high-vaulted basement, slender minarets, single-domed baldacchino, flanked by three semi-domes ending in three exedrae and a broad double portico. The construction was finished in 1548. The construction of a double portico was not a first in Ottoman architecture, but it set a trend for country mosques and mosques of viziers in particular. Rüstem Pasha and Mihrimah required them later in their three mosques in Istanbul and in the Rüstem Pasha Mosque in Tekirdağ. The inner portico traditionally have stalactite capitals while the outer portico have capitals with chevron patterns (''baklava'').
When sultan Süleyman the Magnificent returned from another Balkan campaign, he received news that his heir to the throne Ṣehzade Mehmet had died at the age of twenty-two. In November 1543, not long after Sinan had started the construction of the Iskele Mosque, the sultan ordered Sinan to build of a new major mosque with adjoining complex in memory of his favourite son. This Ṣehzade Mehmet Mosque would become larger and more ambitious than his previous ones. Architectural historians consider this mosque as Sinan's first masterpiece. Obsessed by the concept of a large central dome, Sinan turned to the plans of mosques such as the Fatih Pasha Mosque in Diyarbakır or the Piri Pasha Mosque in Hasköy. He must have visited both mosques during his Persian campaign. Sinan built a mosque with a central dome, this time with four equal half-domes. This superstructure is supported by four massive, but still elegant free-standing, octogonal, fluted piers and four piers incorporated in each lateral wall. In the corners, above roof level, four turrets serve as stabilizing anchors. This coherent concept already is markedly different from the additive plans of traditional Ottoman architecture. Sedefhar Mehmet Ağa would later copy the concept of fluted piers in his Sultan Ahmed Mosque in an attempt to lighten their appearance. Sinan, however, rejected this solution in his next mosques.

The period from the 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 achievement, Sinan emerged from the anonimity 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 Süllimaniye, Sinan (or better the subordinates of his office under his supervision) draw the plans and gave definite instructions for many other constructions. But it is highly improbable that he supervised the construction of any of the provincial assignments .
Sinan built for the Grand Vizier Ibrahim Pasha a mosque and a funeral monument (''türbe'') at Silivrikapı (Istanbul) 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 another ''han'' in Edirne, and between 1544 and 1561 the Taṣ Han at Erzerum. He designed a caravanserai in Eregli and an octogal madrasah in Istanbul.
Between 1553 and 1555, Sinan built a mosque at Beşiktaş, a smaller version of the Üç Ṣerefeli mosque at Edirne, for the Grand Admiral Sinan Pasha. This proves again that Sinan thoroughly studied the work of other architects, moreover since he was responsible for the upkeep of these buildings. He copied the old form, pondered over the weaknesses in the construction and tried then 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 Ahmed Pasha in Istanbul, 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, since he repeated it later in mosques such as the Sokollu Mehmed Pasha Mosque at Kadırga and the Atık Valide Mosque at Űskűdar.
In 1556 Sinan built the Haseki Hürrem Hamam, replacing the antique Baths of Zeuxippus 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 İskender 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 octogonal, 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 Istanbul. 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 Istanbul for Zal Mahmut 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 Christian architects 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, though statically seen, this makes it more stable and easier to build. 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 Moslim world, accentuating the vertical posture of this mosque that already dominates the city.

Conclusion

At the start of his career as an architect, Sinan had to deal with an established, traditional domed architecture. His training as an army engineer led him to approach architecture rather from an empirical point of view, instead of a theoretical one. He started to experiment with the design and engineering of single-domed and multiple-domed structures. He tried to obtain a new geometrical purity, a rationality and a spatial integrity in his structures and designs of mosques. Through all this, he demonstrated his creativity and his wish to create a clear, unified space. He started to develop a series of variations on the domes, surrounding them in different ways with semi-domes, piers, screen walls and different sets of galleries. His domes and arches are curved, but he avoided curvilinear elements in the rest of his design, transforming the circle of the dome into an rectangular, hexagonal or octagonal system. He tried to obtain a rational harmony between the exterior pyramidal composition of semi-domes, culminating in a single drumless dome, and the interior space where this central dome vertically integrates the space into a unified whole. His genius lies in the organization of this space and in the resolution of the tensions created by the design. He was also an innovator in the use of decoration and motifs, merging them into the architectural forms as a whole. He accentuated the centre underneath the central dome by flooding it with light from the many windows. He incorporated his mosques in an efficient way into a complex (''külliye''), serving the needs of the community as an intellectual centre, a community centre and serving the social needs and the health problems of the faithful.
When Sinan died, the classical Ottoman architecture had reached its climax. No successor was gifted enough to better the design of the Selimiye mosque and to develop it any further. His students retreated to earlier models, such as the Şehzade mosque. Invention faded away and a decline set in.

Constructions

During his tenure during 50 years of the post of imperial architect, Sinan is said to have constructed or supervised 476 buildings (196 of which still survive), according to the official list of his works, the ''Tazkirat-al-Abniya''. He couldn't possibly have designed them all, but he relied on the skills of his office. He took credit and the responsibility for their work. For, as a janissary , and thus a slave of the sultan, his primary responsibility was to the sultan. In his spare time, he also designed buildings for the chief officials. He delegated to his assistants the construction of less important buildings in the provinces.
