Koro anthropomorphic libation vessel (figure-cup)
A wooden ritual drinking vessel of the Koro of central Nigeria in which a human figure and a functional hollowed cup are structurally fused into a single carved object.
The anthropomorphic libation vessel is the primary sculptural type associated with the Koro of the Nasarawa-Plateau borderlands of central Nigeria. Its defining formal logic is the integration of human anatomy with vessel function: the carved figure does not merely support a bowl but is the bowl, with the torso serving as pedestal, the arms projecting laterally as handles at sharp right angles, and the crown or chest providing the hollowed cup. This figure-as-container construction subordinates organic anatomy to structural and ritual purpose, producing a form of compressed, load-bearing geometry that the limited documentation records as broadly consistent across the corpus.
In ritual use, the vessel was filled with palm wine or millet beer for communal libation at funerals, secondary burial ceremonies, and agricultural festivals. The anthropomorphic design embeds the idea that the ancestors participate in the drinking act, receiving their share of the harvest through the medium of the sculpted body. Successive libations build the characteristic dense, blackened patina -- thickest inside the bowl and at the base -- that is the primary physical indicator of authentic ritual history. Berns, Fardon and Kasfir's Central Nigeria Unmasked (2011) provides the essential comparative framework for situating Koro vessel figures within the broader Middle Belt artistic sphere, though the specific Koro corpus remains among the less fully documented traditions within that region.
