The triskele, or triple spiral, is a tripartite symbol made up of three interwoven spirals that is closely connected to the triquetra.
The triple helix is an ancient Celtic sign associated with the sun, reincarnation, and the afterlife. The figure above is from the Neolithic “tomb” at Newgrange, which is thought by some to be a sign of pregnancy (the sun moves in a spiral every three months; a triple spiral equals nine months), a concept strengthened by the structure’s womb-like appearance. The symbol also implies reincarnation because it is drawn in a single continuous line, implying a continuous passage of time.
Triskeles are one of the most prevalent Celtic art components, appearing in a range of styles in both ancient and modern Celtic art, particularly in portrayals of the Mother Goddess. They also allude to the Celtic concept of the material realms of earth, water, and sky, as well as their interrelationships.
