Sinan, the Ottoman Empire’s Master Architect

Between the 13th and 16th centuries the Ottoman state grew from a small Turkish principality in Anatolia into a sprawling empire that controlled territory in eastern Europe, western Asia, and North Africa. This transformation was accompanied by the development of a distinctively Ottoman style of architecture. Across the diverse territories that had been gathered under Ottoman rule—and that had little in common in terms of language, religion, or culture—monumental buildings featuring massive domes and soaring pencil-thin minarets were instantly recognizable manifestations of Ottoman grandeur.

The individual most responsible for developing and refining the classical Ottoman architectural style was a builder named Sinan (1491–1588), who served as the empire’s chief architect from 1539 until his death in 1588. During that time he designed hundreds of buildings, including mosques, palaces, baths, tombs, and caravansaries, and oversaw the construction of hundreds more.

Sinan was born to a Christian family in southeast Anatolia. When he was 21 he was drafted into the Jannisary corps, an elite Ottoman infantry force who were recruited as adolescents or young men from the Christian territories of the empire and converted to Islam. He participated in the military campaigns of Suleyman the Magnificent, both as a combatant and as an engineer—the latter allowed him to develop the building expertise that he would put to use later in life.

When Sinan was 47, Suleyman appointed him as the chief architect in Istanbul. Sinan embarked on a series of increasingly impressive buildings. His first large mosque was the Sehzade Mosque in Istanbul, dedicated to the memory of Suleyman’s son and heir who died at the age of 22.

Another of Sinan’s most important works is the Süleymaniye Mosque complex, which remains an essential feature of Istanbul’s skyline. It is almost as large as the Hagia Sophia, a Byzantine church that was converted into a mosque in Ottoman times. The core of the building is a vast dome flanked by two semidomes, which combine to form an awe-inspiring interior space. The ground on which the Süleymaniye complex was constructed slopes toward the Bosporus strait; one of Sinan’s architectural talents was his ability to build on challenging terrain.

The Selimiye Mosque, built in Edirne between 1569 and 1575, is considered Sinan’s masterpiece. In this building, Sinan managed to build a dome roughly as large as the dome of the Hagia Sophia, both having a diameter of about 31 meters. The dome sits on eight piers in an octagon, rather than the usual four larger piers, giving the central space a feeling of openness and weightlessness that is enhanced by the light that filters in from hundreds of small windows.

After completing the Selimiye Mosque, Sinan continued to design smaller buildings until his death in 1588.



Isaac Newton’s List of the 57 Sins he Committed by the Age of 19

Sir Isaac Newton was a mathematician and physicist during the late 17th and early 18th centuries.  He developed the principles of modern physics, especially about motion and gravity, and was considered instrumental in the Scientific Revolution of the 17th century, according to Biography.

Newton is a very multifaceted figure.  He was undeniably a brilliant scientific mind, and a very pious man.  He was also prone to fits of rage, insecurity, and social withdrawal, where he would do no work and isolate himself from everyone.

He had a longtime interest in the study of alchemy, and was searching for the recipe to create the Philosopher’s Stone, which was reputed to turn base metals into gold, and have the power to confer eternal life.

Unlike with his interests in math and physics, his alchemical research was a very private pursuit, and was not driven by money so much as it was inspired by a desire for power over nature, according to Nova.

All of these things taken together build a picture of a man who struggled with mental illness, probably bipolar disorder, according to Futurism.

When he was around 19 or 20, Newton maintained a diary in which he cataloged a list of his sins.  Examining his list, it’s clear that he had problems with anger from a young age.

He identifies, among his sins, “peevishness” with his mother, his sister, and at “Master Clarks, for a piece of bread and butter”.  He lists “falling out with the servants”, as well.

You could say that bad temper and grouchiness are par for the course for a boy of his years, and that would certainly be true, but he also specifies, as number 13, “threatening my father and mother Smith to burn them, and the house over them”.

He also cites multiple examples of physical aggression, punching his sister, beating people, and putting a pin in someone’s hat, so that it will scratch them. He comes across as anxious, egotistical, and dominating.

Newton was not a people person.  He didn’t make friends.  In his personal life, he only had close emotional relation relationships with two people, his niece Catherine Barton, who became his housekeeper in London, and a mathematician named Fatio de Duillier, who was only 25 when he and Newton met.

Their relationship was very emotionally intense, and neither man ever married, which makes some of Newton’s biographers speculate that the men were romantically involved, although there is no proof.

In his professional life, he was very touchy and insecure about his work, and would fly into fits of rage over its criticism, resulting in his withdrawing and refusing to continue his work.  These episodes of withdrawal could last for months.  He shied away from fame, and requested that his papers be published anonymously.

He had sincere religious beliefs, and was a nominal Anglican, but seemed to have a Puritan view of morality and religious observance, as can be seen from his list of sins.

Multiple items reflect his notions of what he owed to God, and his remorse at not always living up to that standard. He had a keen interest in mysticism that was tied firmly to his study of alchemy.

He believed that he had been chosen by God.  In fact, the pseudonym he took to communicate with fellow alchemists was Jehovah Sanctus Unus, which translates to “Holy God”, according to the New York Post.

Despite all of these issues, Sir Isaac Newton was brilliant, and prolific in his work.  His intellectual curiosity was not hampered by what was clearly a difficult personality, and despite his struggles and mood swings he still made a large and incredibly significant contribution to the world of science.
