Of the archaistic ritual vessels excavated from Yuan tombs, those recovered from the tomb of Sai-yin Ch'in-ta-hu at Loyang, Honan, represent, in both number and diversity, the most significant discovery to date. The scholarly community has categorized these earthenwares, crafted in imitation of ancient bronze ritual vessels, as the result of direct influence form the Hsuan-ho po-ku-t'u. while this major epigraphic catalogue, produced by the late Northern Sung court of Hui-tsung, is certainly of great benefit to the identification of ancient vessels, it is difficult to believe that local ritual objects were directly copied from the illustrations of this massive text. Moreover, there are clear differences between the tomb's vessels and those illustrated in the Po-ku-t'u. therefore, it seems likely that an intermediary existed between local ritual objects and the Po-ku-t'u. Close scrutiny of surviving historical texts shows that the ritual items illustrated in the Shao-his chou-hsien shih-tien i-t'u, edited by Chu-his on the basis of the Po-ku-t'u, are both typologically and formally closer (than those of the Po-ku-t'u) to the ritual vessels recovered from yuan archeological sites. There is also evidence that local officials of the Yuan dynasty, in casting ritual vessels, used Chu His's ritual illustrations as models. The combination of vessel types found in the tomb of Sai-yin Ch'ih-ta-hu closely matches that of the illustrations featured in the Shao-hsi chou-hsien shih-tien i-t'u. Thus, it is clear that the Po-ku-t'u, in addition to being reprinted and used by epigraphers and collectors as a direct model for archaistic copies of ancient vessels, also exerted an indirect influence, via ritual illustrations, on the production of ritual vessels for use by popular, non-elite segments of society.
