Bowen Knot - Wikipedia

An angular Bowen knot is such a knot with no rounded sides, so that it appears to be made of five squares. A lozenge-shaped Bowen knot is called a bendwise Bowen knot or a Bowen cross.

The Bowen knot (also known as the heraldic knot in symbolism) is not a true knot, but is rather a heraldic knot, sometimes used as a heraldic charge. It is named after the Welshman James Bowen (died 1629)[1] and is also called true lover's knot.[1] It consists of a rope in the form of a continuous loop laid out as an upright square shape with loops

In Norwegian heraldry a Bowen knot is called a valknute (valknut) and the municipal coat of arms of Lødingen from 1984 has a femsløyfet valknute which means a Bowen knot with five loops.[3]
