Summary
[edit]DescriptionTriskele-Symbol-spiral-five-thirds-turns.svg |
A spiral Triskelion symbol, constructed from mathematical Archimedean spirals. A less wound version of Image:Triskele-Symbol-spiral.svg , with one and two thirds turns in each spiral, instead of two. For a more elaborate spiral triskelion symbol (with three turns), see Image:Triple-Spiral-Symbol-filled.svg, and for the most elaborate version, see Image:Triple-Spiral-Symbol-4turns-filled.svg. For a basic triple-spiral, see Image:Triple-Spiral-Symbol.svg, and for "wheeled" forms of the spiral triskelion/triple spiral symbol, see Image:Wheeled-Triskelion-basic.svg , Image:Roissy triskelion iron ring signet.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 .
