The triskelion or triskele (from rotational symmetry) is an artistic motif consisting of three joined spirals, three bent human legs or three lines extending or bending from the centre of the symbol. The word comes from the Greek triskelés τρισκελής meaning three legs, from the prefix τρι- (tri-) three times and σκέλος (skelos) leg. Although it appears in several places (Galician necklaces) and periods including 3200 BC at Newgrange, it is an essential characteristic part of Celtic art of the La Tène culture of the Iron Age. It is included on the coat of arms of the Isle of Man, and with a central Medusa face on that of the Italian island of Sicily.

According to Celtic culture, the triskelion represents evolution and growth, the balance between body, mind and spirit. It manifests the beginning and the end, eternal evolution and perpetual learning. Among the Druids, it symbolized learning and the trinity of Past, Present and Future.
