The offering bowl shows a figurative representation of a libation ceremony. Four men stand on a platform, holding a large bowl with their arms stretched out upwards. The men wear headgear that resembles a pointed cap. In the centre of the scene is a large vessel from which a small person takes a liquid. Next to it stands a large man. One interpretation of the bowl would be that it was filled with water so that the stars could be reflected in it. Or they filled it with corn beer, which was very often sacrificed. Such libation ceremonies are also known from earlier cultures like the Nasca culture from the Peruvian south coast.
