Many of the vessels from Dežman pile-dwelling sites are decorated with incised geometric designs composed of lozenges, triangles, zigzag and wavy lines, but most of all cross-shaped or circular motifs, frequently set next to or inside one another (cf. Fig. 175). Croatian archaeologist Aleksandar Durman has suggested that these richly decorated vessels were intended for religious rituals and represented the circular celestial sphere. According to him, the decorative motifs stand for celestial bodies, from the sun and possibly moon (circular motifs) to certain constellations of significance in the mythological and religious beliefs of the pile-dwellers in the 3rd millennium BC. Hourglass-shaped figures (Figs. 161, 163, 164) may thus have represented the Orion constellation, wavy lines that of Cassiopeia, while crosses stood for the Cygnus constellation or the Northern Cross.
