Between 1556 and 1565, while he was governing Mashad, Prince Sultan Ibrahim Mirza, nephew and son-in-law of Shah Tahmasp I, commissioned his own atelier of painters and calligraphers to create a sumptuous illustrated version of the Haft Awrang, producing one of the undoubted, and last, masterpieces of the Persian miniature, now in the Freer Gallery of Art, and known as the Freer Jami.
