The thirteen articles in this volume were originally given as presentations at the symposium of the same name organized in June 2018 by the Musée du Louvre and the Musée du Louvre-Lens in conjunction with the exhibition The Empire of Roses: Masterpieces of 19th Century Persian Art. The exhibition explored the art of Iran in the nineteenth and early twentieth centuries, while the nation was under the rule of the Qajar dynasty. The symposium set out to present research on previously unknown and unpublished objects from this rich period of art history. This volume, published with the Louvre Museum in France, is divided into four sections. The first, "Transitions and Transmissions," is dedicated to the arts of painting, illumination, and lithography. The focus of the second section, entitled "The Image Revealed," also considers works on paper, looking at new themes and techniques. "The Material World" examines the use of materials such as textiles, carpets, and armor. The articles in the final section discuss the history of two groups of artifacts acquired by their respective museums.
