The Baghdad School, also known as the Arab school, was a relatively short-lived yet influential school of Islamic art developed during the late 12th century in the capital Baghdad of the ruling Abbasid Caliphate.
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.
Early examples of Baghdad-school miniatures are illustrations from an Arabic translation of Dioscorides’ medical treatise, De materia medica, dated 1224
