Early urban societies feature specialized processes that integrate disparate populations as part of their social construction. One such process is commensalism and the associated display of exotica from interregional interaction. Hosts of a feast between 400 and 300 bce at the early urban centre of Etlatongo, in the Mixteca Alta of Oaxaca, Mexico, displayed pottery that manifested relationships with urban elites at Monte Albán and other regions of Oaxaca, but also expressed connections with something fundamentally different. The hosts sacrificed a greenstone sculpture in the Mezcala style from Guerrero state, located to the west and previously unknown in Oaxaca aesthetics. The discovery of this figure contributes to reassessing the extent of interaction during a time often marked by regionalism in Oaxaca as well as providing information on the little-known Mezcala civilization. A relational ontology explores how the discovery of this agentive object and the alterity of its aesthetics facilitates understanding perceptions of distant others or imaginaries, and how such entanglements facilitated processes of status differentiation for nascent urban elites, particularly their role as mediators.
