The function and use of such depot vessels with relief decoration are still largely unknown. All are decorated with images of gods. The lower depiction shows essential features of the so-called water lily god; the upper one shows a deity with a triangular decorative plate and a knotted ribbon hanging from his nose. The iconography of the vessel appears to be a kind of cosmogram, as the water lily god belongs to the uppermost layer of the underworld, which was thought of as a watery surface, while the god with the nose ornament resides in heaven.
