Ritual artifacts have been central to archaeological studies. Taiwanese archaeologists have long considered the small pots which belong to the late Metal archaeological materials of Taiwan’s East Coast, as analogous to the sacrificial pot diwas recorded in Amis ethnographies, marking the pots as a diwas type of sacrificial pot from a typological perspective. This type of sacrificial pot has become an ethnic symbol to correlate Jingpu culture (Amis culture) and the Amis people in the eyes of the archaeologists. However, the direct analogy between the archaeological materials and the material culture in Amis ethnographies is flawed in its interpretation of buried objects and classification of archaeological materials, as the meanings and information on both sides are complex and incomplete. This article examines and analyzes the sacrificial pots of Jingpu culture and Amis people on the basis of the above observation. The article starts from a literature review of how Taiwanese archaeologists have analogized Amis earthenware with sacrificial pot diwas through archaeological materials to construct and interpret Jingpu culture. In the second stage, the article gives a review on past ethnographies and elaborates on the incomplete state of information and meanings borne by Amis sacrificial pots in ethnologists’ records. Finally, the article proposes an “ethnoarchaeological study on the social life of sacrificial pots in Amis Dongchang village” as a potential approach for subsequent research on this topic. This approach deals with Amis people’s classification practices, daily practice, and the buried formation processes of sacrificial pot.
