Today in the Middle Ages: April 15, 1489

Ottoman architect Koca Mi’mar Sinan Aga , usually referred to as Sinan, was born on April 15, 1489. His innovative approach was to transform the Ottoman civic and religious architecture of the Ottoman classical period.

Sinan, like his contemporary Michelangelo in the West, came to architecture from a military background and began with a pragmatic approach. However, he transformed the architecture design of his day from an assemblage of parts to a unified structure. The Selimiye mosque in Edirne, Turkey, generally considered his masterpiece, was completed when the architect was more than 80 years old.
