Abstract
European prehistoric decorative art abounds in motifs that are not humble decorative elements but seem to be significant signs. Circles, concentric circles with or without a dot in the centre, circles divided into four, six or eight equal segments (sun/star-crosses) and often round decoration complexes filled with different spiral motifs are generally considered sun symbols by archaeologists. It is predominantly accepted that sun cults dominated the belief system of the European Bronze Age. These symbols can be found as a single sign on many artifacts, especially luxury ones like weapons, jewels and fine pottery. Although they were widespread in Europe in the Bronze Age the Carpathian Basin has an outstanding collection of such archaeological material. A detailed comparative study of atmospheric optic phenomena and Bronze Age symbols revealed similarities between many abstract symbols and manifestations of atmospheric phenomena in the sky. The investigation resulted in the assumption of the significance of such symbols in Bronze Age visual culture. The study attempts to identify, present and reveal the role of simple as well as the more complex celestial symbols in the relationship between prehistoric people and their environment based on this argument.
