What is the Celtic Shield Knot?
Four versions of the shield knot
There are many variations to the Celtic shield knot, with modern stylized versions also available. However, the defining feature of the shield knot is its four clear corners. This symbol is usually just a looped square, but sometimes it may contain a circle in the center.
Like all Celtic knots, this knot also has no beginning or end, and is formed with a single thread weaving and interlacing upon itself. There are no loose ends to the pattern, which gives it a continuous, endless appearance.

- Celts – The shield knot became popular in Celtic culture during the period of Insular art, where interlacing patterns, such as spirals and knots, began to flourish.
- Christianity – The Christians took over the symbol of the shield knot and called it St. Hannes cross or St. John’s Arms.
