The Trinity Knot is a classic Celtic symmetrical design of three arcs interlaced to form a triangular shape. Did you know that the Trinity Knot is also called the Triquetra, meaning Triangle in Latin? And, it is often thought to be related to the Triskele, a triple spiral motif from ancient Celtic times.
Some say it is a symbol that came from the Christian Monks who converted the Celts, while others say it is originally a Celtic design. While these theories are still debated, we do know that the symbol appeared in the West in the 7th or 8th century in Norse Viking and Celtic cultures. In the 9th century it appeared as decoration in the Book of Kells. The Book of Kells is the world’s most famous medieval manuscript, containing the four Gospels of the life of Jesus Christ written in Latin. This beautifully decorated book is proudly homed in Trinity College Dublin, Ireland.
The Trinity Knot is a religious symbol, which has been used for years in both Christian and Pagan heritages. The three arcs believed to represent many things, as many cultures use it and each culture have chosen their own meanings. For example, Christians believe the Trinity Knot represents the Father, Son and Holy Spirit. Others have interpreted it to be a symbol for Earth, Sea and Sky, or Earth, Fire and Water. And, some cultures say it represents eternal love, and is often referred to as the Irish Love Knot. Archaeologists have found the Celtic Knot near lunar and solar symbols on Celtic sites, so the Celts must have believed it to represent something of the lunar and solar phases.
You’ll often see the Celtic Knot with a circle looping through the three arcs, emphasising the unity of the three (debated) forces. Historically, the Trinity Knot is commonly found on metalwork and stone crosses, but in modern day culture it can be found on jewellery, clothing, accessories, interior décor, etc. People will often gift another with the Trinity Knot, usually at weddings, engagements and anniversaries, as it shows a wish of longevity.
