Bellied, thin-walled jug with a deep rim and domed base. The object has a strongly retracting wall. Its neck is completely fragmented. The ceramic was smoothed and slurried on both sides. Its exterior is primed, painted and lightly polished. The paint and primer are slightly eroded. The object has a red-brown base colour, which is painted black-brown on the outside of the vessel. On the wall there is a high, circumferential frieze showing two intertwined wavy bands (guilloche motif). The frieze is bordered by several circumferential lines and bands. The interior of the object remains undecorated. Symbolic meaning: the guilloche motif is often interpreted as two snakes intertwined (Ferrero 1975: 405). According to Lothrop 1926: Nicoya black line ware. Cultural significance: the type has been documented in burials. The guilloche motif is considered a diagnostic indicator for the late phase of the Policromo Medio (1350-800d.C.). It occurs above all in the groups Gillén Negro sobre Café Claro, Papagayo Policromo (1350-800d.C.), Jicote Policromo (1350-1000d.C.) and Mora Policromo, variedad Guabal (1200-800d.C.). (Künne 2004)
