Trinity Knot (Triquetra)

The Triquetra, more commonly known as the Trinity Knot, is a Celtic symbol of ancient origin and one of the earliest symbols of Christianity, predating the crucifix by hundreds of years.  The triquetra is most simply represented by three interlocking circles.  Often the triquetra is found illustrated with three fish in a similar shape.  This three in one concept could have symbolized earth, air, and water, or mind, body, and soul.  When Christianity was introduced to Ireland, the Triquetra became known as the Trinity Knot, which symbolized the persons in one God: the Father, the Son, and the Holy Spirit.  It is used in this manner in many of the early Christian illuminated manuscripts such as the Book of Kells.  The combination of the trinity knot into rings, linens, or other bridal designs is associated with eternity and eternal love.
