"As Christianity transformed Mediterranean culture and art in the third and fourth centuries after Christ, so Buddhism, in the same centuries, effected a theological and esthetic revolution in the life of China. While Confucianism retained its political power, Buddhism, mingling with Taoism, became the dominating force in art, and brought to the Chinese a stimulating contact with Hindu motives, symbols, methods and forms. The greatest genius of the Chinese Buddhist school of painting was Ku K’ai-chih, a man of such unique and positive personality that a web of anecdote or legend has meshed him in."
