The vessel on display is a hemispherical bowl manually fashioned in clay. The external surface was polished and covered with incisions forming a rich geometrical pattern. It was probably used for food consumption rather than preparation. The vessel was decorated with precision and skill. It may suggest it was an element of a decorative ‘table set’. Geometrical patterns decorating vessels from that period may have been their makers’ trademarks. One may suppose that they used similar ornaments to decorate their bodies, dwellings, and objects of daily use. The described vessel originates from the Kraków-Częstochowa Upland. It was found in Kobylany, in the Pod Słupami Cave in 1879. It is the oldest vessel of this type in the Polish territories.
