A comprehensive comparison is made in this paper for the aesthetic of nature between Shijing(Book of Poetry),an anthology of Chinese ancient poetry and Chuci(The Songs of South),a masterpiece of QU Yuan. It points out that the background materials for analogy in Shijing are the scenic hills and waters,which are described as they are in simple language,while in Chuci,the materials are much richer with imaginary scenery and flowery language.In the former,water is used to symbolize the lingering sorrow and elaborate the emotion and atmophere,with the poet's feelings and the nature greatly separated from each other. In the latter,QU Yuan describes the natural scenery in a sentimental tone and he always combines the nature's danger and treacherousness and the hardship of human life harmoniously into one. In the former,the sense of aesthetic for nature goes through the changs from awing the deity of nature to regarding the hils and waters as analogical materials and pleasant company. But in Chuci,from the very beginning,the poet shows his love and closeness to the deity of nature. Moreover,compared with Shijing,the sense of aesthetic in Chuci is stronger,the poet's self-consciousness has been improved,and the artistic horizon has been broadened. And it offers an abundant and precious creative experience for the coming of the new epoch of landscape poems.
