A triskelion or triskele is a motif consisting of three interlocked spirals, or three bent human legs, or any similar symbol with three protrusions and a threefold rotational symmetry. Both words are from Greek "τρισκέλιον" (triskelion) or "τρισκελής" (triskeles), "three-legged", from prefix "τρι-" (tri-), "three times" + "σκέλος" (skelos), "leg". Although it appears in many places and periods, it is especially characteristic of the Celtic art of the La Tène culture of the European Iron Age.
A triskelion is the symbol of Sicily, where it is called trinacria, as well as of the Isle of Man, Brittany and the town of Füssen in Germany.
