Triquetra – the Trinity Knot
Also known as The Trinity Knot. Like all Celtic knots the triquetra is constructed of one continuous line interweaving around itself symbolizing no beginning or end, an eternal spiritual life.
The Celts favored the idea that everything important in the world came in threes; three stages of life, three elements, three domains; earth, sea and sky, past, present and future. The triquetra is sometimes drawn weaving around a circle, symbolizingthe unity of the three parts.
Christians adopted the knot
The Christians adopted this knot because it fitted in so well with their belief system. To them it came to represent The Son, Father and Holy Spirit.
Runestone from Uppsala, Sweden
It also closely resembles three interlocking fish, the fish being an ancient Christian symbol which predates the crucifix by hundreds of years. Variations of this symbol have been found around the globe. Pictures of interlocking fish can be found on Egyptian and Roman artifacts, and Scandinavian runestones have been found displaying the three-cornered geometric shape.
Although it is thought that this symbol was around before Christianity, The triquetra and similar Celtic knots were prevalent in Christian art work all over Britain and Ireland.
Intricate Celtic knots can be found on stone monuments and throughout the beautiful illuminated manuscripts created by the Celtic monks.
