中国古代墓葬的图像系统中,佛、道、儒共存的现象比较突出。通过对历代墓葬天界图像的分析,发现佛、道天界图像系统的出现远远晚于“天圆地方”和“天象方位”的宇宙图式。宇宙图式贯穿历代墓葬,而佛、道图像体系呈现阶段性特点。“天”之信仰的宇宙图像系统是佛、道、儒三教得以共存的根本前提。佛、道的天界图像系统是在宇宙图式的基础上延伸出来的,因此,不能把关于天界的图像简单定论为佛教天国或者道教仙界。 In ancient Chinese tombs’ image system, Buddhism, Taoism and Confucianism coexist more prominently. Through the analysis of the celestial celestial tombs of ancient tombs, it is found that the appearance of the image system of Buddhism and Taoism is far behind the cosmic patterns of “heavenly and round place ” and “heavenly azimuth ”. The cosmic pattern runs through the tombs of all ages, while the image system of Buddhism and Taoism shows stage characteristics. “Sky ” belief in the universe image system is the fundamental premise that Buddhism, Taoism and Confucianism can coexist. Buddha, Tao’s celestial body image system is extended on the basis of the cosmic schema, therefore, the image of the celestial world can not be conclusively defined as the Buddhist heaven or the Taoist celestial world.
