Potency of imagery in SS brotherhood was not lost on its leader, Heinrich Himmler, and was clearly in his mind when early in life of organization he instituted Ring der SS (April 1934). Totenkopf ring prominently featured runes and mystical symbols of SS, symbols that played a significant role in magnifying the veil of obscurity and mystique that covered organization.
