One basic version of a "wheeled" form of a Triskelion or Triple Spiral symbol, containing three double spirals which branch out into partial circular arcs which enclose the whole figure. Inspired by various Celtic decorative motifs, but this version is constructed from mathematical Archimedean spirals. For a more ornate "wheeled" triskelion, with an enclosing spiral instead of a partially enclosing circle, see Image:Triskelion-spiral-threespoked-inspiral.svg . For other versions, see Image:Roissy triskelion iron ring signet.png or Image:Triple-spiral-wheeled-simple.svg .

For other, non-wheel versions of the triskelion or triple-spiral symbols, see Image:Triskele-Symbol-spiral-five-thirds-turns.svg , Image:Triple-Spiral-Symbol-filled.svg , Image:Triple-Spiral-Symbol-4turns-filled.svg , Image:Triskele-Symbol-spiral.svg , or Image:Triple-Spiral-Symbol.svg . For a spiral triskelion with a hollow triangle in the center, see Image:Triskele-hollow-triangle.svg . For versions of a triple-spiral labyrinth, see Image:Triple-Spiral-labyrinth.svg and Image:Triple-Spiral-labyrinth-variant.svg .

% PostScript program to display an Archimedean spiral by approximating
% it with Bezier curves.  Can display a double spiral (two spirals
% rotated by 180 degrees with respect to each other).
%%%  Parameters:
                 % centerx = horizontal coordinate of center of spiral
                 % centery = vertical coordinate of center of spiral
                 % rotf = degrees to rotate
/sepwid 110 def  % width separating successive turnings of spiral
                 % (half this if double spiral is selected)
/incrm 15 def    % insert a curve point after this number of degrees
                 % CHANGED TO 30 FOR INNER SPIRALS
/double 1 def    % change to 0 to display single spiral
/quadruple 1 def % change to 0 to display single/double spiral only
