One of the first modular elements: black and white square. There is no neolithic or any later ornamental art without it (see, D.K.Washburn, D.W.Crowe: Symmetries of Culture, University of Washington Press, Seattle and London, 1988; S.V.Jablan: Theory of Symmetry and Ornament, Mathematical Institute, Belgrade, 1995); a possible origin of the swastika symbol. Ornaments (right) are obtained by overlaping of the basic ornaments (left).

Curvilinear form of the same modular element and ornaments derived from it.
