Triquetra means “triangle” or “three” (tri-) “cornered” (Quetrus). It is made up of three intersecting vesica Pisces. The Vesica Pisces is the shape created by the intersection of two congruent circles. A triquetra symbol is sometimes interlaced with a circle.
An ancient Celtic symbol, the triquetra is considered one of the oldest; dating back to as early as 500 BC when it was used to symbolize the triple goddess (maiden-mother-crone). Over the centuries it has become the symbol for the Holy Trinity among Christians in Ireland. The symbol is often used to represent the 3 fundamental elements – air, water, and earth or the infinite cycle of life. It is also known as a rune of protection.
