What Is the Symbolic Meaning of the Triquetra?

The triquetra, or trinity knot, holds several meanings, but most refer to the interconnectedness of three separate entities. Christians believe that the three points represent the Holy Trinity, and pagans believe that the points represent earth, air and water. The design can also represent life, death and rebirth.

A circle signifying eternity sometimes accompanies the traditional triquetra symbol. To Christians, the circle signifies God's eternal love, while non-Christians may interpret it as the eternal circle of life. Personal beliefs typically determine the meaning people ascribe to this symbol. The exact origins of the trinity knot are unknown, but it probably stems from Christian monks or ancient Celtic culture.
