The Triskele sign, also known as the Triskelion, is a trilateral symbol made up of three spirals that are interwoven. It appears on the Newgrange kerbstones, which date from around 3200 BC, and is often recognized as one of the oldest Irish emblems in existence. Triskeles appear frequently in both ancient and modern Celtic art, evoking the Celtic understanding of the three domains of material existence: earth, water, and sky (and all their interconnections). The three worlds (spiritual, physical, and celestial) are also said to be represented by the symbol.
Life-death-rebirth, past-present-future, earth-water-sky, and creation-protection-destruction are some of the Trinity connections linked with the triskele. Each one focuses on a different area of personal development, human evolution, and spiritual improvement. According to one belief, the triskele depicts rebirth since it is made up of a single continuous line that can be compared to the unbroken passage of time. It reflects the process of always progressing toward a state of awareness and enlightenment in this setting. Another idea claims that the triskele at Newgrange is designed to represent pregnancy.
This Neolithic edifice has a womb-like look, and the sun spirals every three months in its travels, with the symbol’s three spirals indicating a total of nine months. With so many interpretations and meanings, it’s no surprise that different civilizations and cultures have borrowed the triskele over the millennia. It appears on the Füssen coat of arms (Germany), as well as the national flags of Sicily, the Isle of Man, and Brittany, and is incorporated into the current Irish Air Corps insignia and the United States Department of Transportation logo.
