Books, such as the Coran, were brought back to be integrated in Royal libraries, such as the Bibliothèque Royale de Fontainebleau, to create a foundation for the Collège des lecteurs royaux, future Collège de France.[1] French novels and tragedies were written with the Ottoman Empire as a theme or background.[25] In 1561, Gabriel Bounin published La Soltane, a tragedy highlighting the role of Roxelane in the 1553 execution of Mustapha, the elder son of Suleiman.[25][27] This tragedy marks the first time the Ottomans were introduced on stage in France.[28]
