Western pastorals can be traced back to Roman times while Chinese ＂Tian Yuan Shi＂ （田园诗）, which may serve the best similarities, appeared as early as in East-Jin Dynasty （316-420 A.D.）. Poets in both cultures praised country life and wanted to have a rest in the nature. Despite these similarities or ＂parallel＂, there are also some differences in two kinds of literature which have been widely discussed. Among all the differences, nature＇s function-spirit purification and consolation or a refuge-in fact varies in Chinese and western pastoral poetries. This means what the authors of these literary works expected from nature by panegyrizing nature highly and indulging themselves in nature differ significantly in two cultures. This phenomenon has been under thoughtful investigation. Different cultural, religious and historical backgrounds in Chinese and western cultures are exploited to explain these differences. However, these explanations are all phenomena themselves and lack the definitiveness and inevitability. The different western history opposite to the absence of subjective rights in China, which can find further resource in cultural geography, is examined in this paper to provide a more desirable answer.展开更多
