The study of materiality may reveal social and economic aspects related to the archeology of ethnicity when situated in its historical context. In this sense, the technological choices and plastic decorations applied to utilitarian ceramics, “monkey jars” containers, and the interpretation of other material categories show a context related to the flow of materials in the Santarem (Para) region during the 18th and 19th centuries. These flows demonstrated, besides the presence of indigenous people, the enslaved Africans in the Colonial Amazon. The objective of this paper is to discuss the context of the African Diaspora with data on catch zones, boarding and reloading rates and elements of the material culture capable of revealing the agency of these people subject to the colonial difference. © 2019, Sociedade de Arqueologia Brasileira.
