The great leaders in periods preceding the T'ang dynasty paved the way to the culmination which took place in the Sung period, and thus the fruit of that prolonged activity is seen ripening between the tenth and the thirteenth centuries. Through the gropings of the primitive period, the heterodox philosophies and the mystic stirrings of Buddhism, Eastern thought had arrived at an unquestionably noble comprehension of existence. The impersonal mystery of the universe, its mighty principle, its manifold manifestations and the secret which unveils itself in the innermost soul of things are the conceptions which form the inspiration of Chinese painting. These lofty thoughts are the source of that spirituality which declares itself therein with such nobility. The religion to which they are due will seem perhaps, to certain people, to be broader and less trammeled than our own. There is no doubt that the entire Far East was under the spell of its grandeur. Up to this point art had sounded every depth and attained the highest summits of human achievement. Thenceforward it concerned itself with varying manifestations which were only the different modes of a formula that was still flexible, until the time when--the great inspirations of the past forgotten--there appear signs of a spirit on the quest for realism, emerging from the ancient tradition. This is the distinctive note in the evolution of Chinese painting under the last two dynasties. It would seem as if, even in this guise, a universal need of the mind is being satisfied, a need which we, too, have known after experiencing a chilling academicism, and when modern culture had overthrown the ancient idols. Chinese painters have thus completed a round analogous to that traveled by our own artists. [Illustration: PLATE XXV. TIGER IN A PINE FOREST Eighteenth to Nineteenth Centuries. Collection of V.
