A triskelion, or triskeles, is an ancient motif consisting either of a triple spiral exhibiting rotational symmetry or of other patterns in triplicate that emanate from a common center. The spiral design can be based on interlocking Archimedean spirals, or represent three bent human limbs. It occurs in artefacts of the European Neolithic and Bronze Ages with continuation into the Iron Age, especially in the context of the La Tène culture and of related Celtic traditions. The actual triskeles symbol of three human legs is found especially in Greek antiquity, beginning in archaic pottery and continued in coinage of Classical Greece.
