The Trinity knot is also called the Triquetra and is known to be mainly Celtic, but it was also found in Japanese culture as, Musubi Mitsugashiwa, also in Chinese, Korean and Pagan German cultures, etc.
Of course each one of them attached their own significance and meaning to this magnificent design element, such as, symbol of threefold nature of the Goddess as mother, maiden and crone, creation and complexity of life, earth, fire and water, and even was used and somehow associated with lunar and solar phases.
The Trinity Symbol comes from ancient times.
It was and is part of Wiccan and Neopagen, Christian/Modern era and will never loose its attractiveness and esthetic value and will always be used in many forms of art and design.
The Celtic Christian church used it to represent the Holy Trinity, intertwined unity and today it is a perfect symbol for marriage, togetherness and family.
Its form and design greatly signifies the complexity, and yet at the same time, simplicity of family unity and the forever union, happily ever after...
