As before stated, a special philosophy was associated with this tree and its flowers. The white petals scattered on vigorous branches had long typified an inner soul, whose purity was the very likeness of virtue and of tenderness. Chung Jen, who in the eleventh century wrote a treatise on the painting of the plum tree, explains in his chapter on "the derivation of forms" that it is a symbol, a concentrated form, a likeness of the universe. The great fundamental principles mingle harmoniously within it; they express themselves in its shape and reveal themselves through its beauty. Similar to this was the philosophy associated with the bamboo, which endured up to the fifteenth century. The subtle monochromes of Lu Fu show branches of flowering plum swaying in the breeze. In the great works of Wang Yüan-chang trunks of old trees, still bearing hardy blossoms, stand proudly in the magical radiance of the moon. Vibration and power, grandeur and majesty, such are the qualities which were still sought amidst the severe conditions imposed by the use of black and white. Here we feel that the creative force is not yet spent. We find it equally fresh and vigorous in the ink bamboos of Wên Chêng-ming in the sixteenth century. In landscape, however, new elements appear which mark a decline. I have already laid stress on the overladen composition which developed in the Yüan epoch. This was still more noticeable in the Ming period. When pictorial art has had a long series of masters, a certain eclecticism is infallibly produced. This leads to the rejection of the direct study of nature, in favor of viewing it only through the eyes of the old masters. This phenomenon appeared in China as well as in Europe. The landscape painters of the Ming period studied the technique of the T'ang and the Sung epochs and codified their system of lines, arranging them in series according to types and schools; in short, they drew from these a ready-made technique by which they were controlled. Turning from nature they yielded to imagination. They delighted in painting fanciful landscapes and were inclined toward images that were more external and less inspired than in the past. Their works, however, were invested with great charm, and the impossible disposition of their clustering peaks and oddly cleft rocks cannot but appeal to the imagination. In these overladen compositions the unity of the picture is lost. We are no longer in the presence of a simple and forceful idea, but behold a thousand incidents, a thousand little details, exquisite in themselves, but which require a search. It is a new conception of landscape. We may possibly prefer the gripping formula of Sung and Yüan art, but we are forced to acknowledge that this later work has great charm and extreme refinement.
