Abstract:Shiwugong, first seen in the Changling Tomb of the Ming Emperor Chengzu, Zhu Di, is one of the most notable symbolic stone ritual objects with mimetic and ceremonial features in the imperial mausoleums of the Ming and Qing Dynasties. Composed of “Shi Gong An” (stone offering table)and “Shi Gong Qi”(stone offering vessels), Shiwugong bears a close relationship with the“San Gu Zu”(three sacra) used in Buddhist rituals. This study focuses on the censers within the thirteen Ming Dynasty tombs, employing close-range photogrammetric surveying to record three-dimensional data of the censer’s forms. By arranging the imperial tombs chronologically, a comparative analysis was conducted on each censer in terms of shape, dimensions, themes, and carving techniques. This research traces the historical origins of the censers within the Shiwugong of the thirteen Ming tombs, summarizing the patterns of evolution in their morphological characteristics.
