A powerful reconstruction of a rare Tiwanaku / Wari-style Kero (ceremonial drinking vessel), circa 600–1000 CE. Carved from a single piece of hardwood, this beaker features a striking supernatural face in high relief — likely representing a deity or ancestral being with fanged mouth, powerful eyes, and elaborate headdress. The body is covered in deeply carved geometric motifs typical of the Tiwanaku-Wari artistic tradition: stepped frets, meanders, and abstract symbols that encode cosmological and political meaning. These vessels were central to Andean ritual life. Used in pairs during feasts, they held chicha (maize beer) and served to seal political alliances, marriages, and sacred pacts. Drinking together created a binding social and spiritual contract.
