Bowen cross (Accepted)

The “Bowen cross” is a Bowen knot turned crosswise, with its loops made angular.  Its name is a Society invention, and the cross itself was originally thought to be unique to the Society; but angular Bowen knots are a valid artistic variant, dating from 1530 [Woodcock & Robinson 149], so the Bowen cross is likewise valid.

Adler des Berges bears as a badge:  Per saltire sable and argent, a Bowen cross counterchanged.

Talan of Skye bears:  Purpure, a Bowen cross and a chief argent.
