Bowen knot

Heraldic knot

The Bowen knot 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 and is also called true lover's knot. It consists of a rope in the form of a continuous loop laid out as an upright square shape with loops at each of the four corners. Since the rope is not actually knotted, it would in topological terms be considered an unknot.
