After reading your article, I understand that there is no doubt that the architect Sinan left an indelible mark in the Ottoman Turkey of the 16th century. Prior to it, the Turkic architecture was already distinguished by its significant works of architecture, i.e. strong and solid buildings, various knowledge, but this master of his work went even further, i.e. perfected and developed what was before him. In his creations, he used not only the accumulated experience, but also improved the previously existing system of statics, the strength is the mosque Şehzade Bayezid, where he in the middle installed a dome consisting of 4 semi-cupolas, before this variant he experienced in the mosque Mihrimah Sultan in Üsküdar , located near the bridge, the dome of which consisted of three half-cupolas.
The cathedral mosque Şehzade from the point of view of mobilization of external facades is considered one of the most important creations of the architecture of the master of Sinan, in particular it concerns minarets with its relief convexities and therefore in the Ottoman architecture this mosque is considered the very first, and maybe the last beautiful mosque - a sample of architectural art.
