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.
