The simplest of Celtic Knots symbolizing a triune God. The Celts were very familiar with the idea of the trinity, everything came in threes; the three stages of womanhood:maid, mother, crone, and the three elements: earth, fire, water and Christianity embraced this knot to symbolize the Father, Son, and Holy Ghost in many of the early Christian illuminated manuscripts such as the Book of Kells. The combination of the trinity knot into rings, linens, jewelry, and other bridal designs is associated with eternity and eternal love. The trinity predates the crucifix by hundreds of years.
