The frontispiece to a book, “The Epistles of the Sincere Brethren,” dated 1287, demonstrates that the main stylistic elements of the Baghdad school survived to the last. This illustration, in the Mosque of Süleyman in Istanbul, again shows realism in detail while maintaining an overall decorative quality. The authors of the book are depicted with their scribes, and attention is drawn to the faces. By the early 1300s, the school had died out, and painting in the area began to take on many characteristics of the Mongol schools.
