Cup with Four Faces, 600-1000. Central Andes, Wari people. Stone with shell inlay; overall: 9.5 x 9.2 cm (3 3/4 x 3 5/8 in.). The identity of the four, wide-eyed faces on this cup is unknown. Equally mysterious is the cups function. It seems too small to be used for drinking beer at the feasts the Wari sponsored to put others in their debt. The size may suggest the cup was used in more intimate circumstances, perhaps to make libations to sacred forces that animated the ancient landscape.
