more brilliant period in a long series. Again architecture was clothed in sumptuous color such as has never been surpassed, and the arts of the book attained supreme perfection. With the coming of the Safavids ( 1501-1734), the last of the great artistic phases, the inexhaustible vitality of the Iranian artistic tradition was once more demon- strated. Shah Ismael ( 1501-1524), Shah Tahmasp ( 1524- 1576), and Shah Abbas I ( 1589-1627) presided over courts in which artists ranked with ambassadors, one more epoch in which art was held the attribute of kings and the most worthy expression of the state's power. Misfortunes thereafter afflicted Persia. A series of weak and incompetent rulers, a cruel and bloody inva- sion from Afghanistan ( 1722), a temporarily successful but violent and exhausting imperialistic revival under Nadir Shah ( 1729-1747), left the country in no condi- tion to adjust successfully to a developing Europe with its industrial productivity and new lines of commerce which by-passed Iran, so that she was condemned to frustration and perilously declining power under the uncouth Kajars in the nineteenth century. But the significant feature of Iranian history is its power of survival and revival. She has so often responded to catastrophe and depression with a new and creative burst of vigor that her ability to recover has become something of an historical mystery. The restoration of the country under Riza Shah Pahlavi ( 1925-42) dem- onstrated that the nation still had reservoirs of energy and adaptability. Despite the crippling loss of intelligent patronage of the arts for nearly two centuries, the disintegration of their essential economic support, the temporary weaken- ing of the national tradition, the imposition through the prestige of European power of tasteless styles of the industrial era, the corruption of native taste incidental to poverty and the demoralization of standards in educa- tion, religion, and social life, -- despite all this the artistic spirit of Iran is not dead. There are still draftsmen of superb capacity. Work in some of the ceramic techniques is as good as ever, and the best of the contemporary carpets, as yet not seen in the West, in color and weav- ing-skill hold their own with their famous prototypes. A revival of design, the foundation and soul of Iranian art, awaits discipline and a deepening of the national life, the slowly returning prestige of the artist, and the inspiration of a serious and informed clientele, indis- pensable to high achievement.
