The trinity knot is one of the most enduring symbols of Irish and celtic art. It is also commonly called by its Latin name, triquetra, which literally translates as "three cornered symbol". The trinity knot is used throughout Irish metalwork and literature, as a decoration in the margins of ancient manuscripts, and etched in stone on Ireland's high crosses. For the pagan celts, the triquetra symbolized eternity, or the unity of Mind, Body and Spirit. The symbol can also be worn to represent the Holy Trinity of Father, Son and Holy Spirit.
