Abstract: Symmetry patterns attributed to some of the G20 (rosettes) or G21 (friezes) symmetry groups are decribed on both gold and “silver-like” (graphite) decorated pottery from the Late Chalcolithic (middle-end of the 5th millennium BC) Varna I Chalcolithic necropolis (Varna culture) and from sites of the Kodžadermen-Gumelniţa-Karanovo VI culture (KGK VI) in Eastern Bulgaria.
Keywords: symmetry, pottery, gold, graphite, Chalcolithic, Bulgaria.
