BeschrijvingTriple-Spiral-Symbol.svg	The Triple Spiral symbol, based on motifs found at the prehistoric site at Newgrange, Ireland, and used as a neo-pagan or Triple Goddess symbol. This version is made up of mathematical Archimedean spirals. For a version with thicker lines, see Image:Triple-Spiral-Symbol-heavystroked.svg . For spiral triskelions, see also Image:Triple-Spiral-Symbol-filled.svg , Image:Triple-Spiral-Symbol-4turns-filled.svg , and Image:Triskele-Symbol-spiral.svg . For "wheeled" forms of the spiral triskelion/triple spiral symbol, see Image:Wheeled-Triskelion-basic.svg , Image:Roissy triskelion iron ring signet.svg , Image:Triple-spiral-wheeled-simple.svg , or Image:Triskelion-spiral-threespoked-inspiral.svg . For a spiral triskelion with a hollow triangle in the center, see Image:Triskele-hollow-triangle.svg .
