Summary

[edit]
Description A quasi-celtic cross made of large symmetrical knot with a circle interlaced through its center. The knot is made up of straight lines which are vertical, horizontal, or at 45° angles, and of circular arcs all of the same radius. If the large circle were to be removed, then the over-under interlacing of the crossings of the horizontal and vertical lines at the center would have to be reversed to preserve the alternation of the knot interlace pattern (see Celtic-knot-cross no circle.svg).
