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.

History of the Celtic Shield Knot
