Since writing the previous article http://armanen.blogspot.co.uk/2017/03/the-trollskors-possible-origin.html I found reference to a strikingly similar symbol in Walther Blachetta's Das Buch der Deutschen Sinnzeichen which Blachetta refers to as Die Bauge:
"Die Bauge is the symbol for the- desire for a quick return- . It is a variation of the symbol of Die Brille, only that both spheres of life are still open here. Closely related to it is the Blitzbündel and the double spiral. - Baugen were laid by the Teutons in the grave of good friends and loyal followers." (pages 38-39)
(WOTANS KRIEGER's translation-please note that I have retained the German 'Die Brille', which means 'spectacles' for stylistic reasons. 'Die Bauge' has no English equivalent and thus remains untranslated but there may be an etymological link with 'Der Bogen' which means 'bow' , 'arc' and 'arch' and it certainly resembles the arch in form.)
Die Bauge very closely resembles the trollkors and this may very well be an esoteric interpretation of this enigmatic symbol. Unfortunately Blachetta does not mention a source for his entry and does not clarify what material Die Bauge as an amulet was constructed from but my guess would be that it may have been iron which was a relatively cheap metal and had special protective properties.:
Die Bauge was a symbol for the Wiederkehr, the return to life of the dead friend or follower. The two spiral ends of the symbol represent the 'spheres' of life. Blachetta compares this symbol with Die Brille:
"Die Brille is the symbol-of the return and of the resurrection-. It is an amendment of the dumbbell. There (WOTANS KRIEGER's note-'there' referring back to the dumbbell-Die Hantel) only opposition, here the continuation of life, and indeed out of death through the Origin (WOTANS KRIEGER's note-Armanen term translated from Das Ur) to a new existence. - Die Brille is a much beloved symbol in folk art and frequently found on farmhouse door arches in Westphalia. Related to it is the symbol with the rams horn, the cradle and the Jar rune." (pages 36-37)
Die Brille resembles a pair of round spectacles, joined together by an arch or a bow. Again as with Die Bauge we have the concept of resurrection or returning to life. This is also reflected in the Listian concept of Arising-Becoming-Passing Away-New Arising. Energy cannot be destroyed, only transformed and the life force is of course a form of energy.
My readers will note Blachetta's comparison with the Blitzbündel and more information on this symbol may be found on http://armanen.blogspot.co.uk/2015/05/an-esoteric-interpretation-of-das.html and http://armanen.blogspot.co.uk/2015/12/the-trisula-and-its-associations-with.html . As I commented in the earliest of the aforementioned articles the Blitzbündel is a symbol of both birth and rebirth. The astute observer will notice that the symbol appears to be composed of 2 Perthro runes. It is beyond doubt that one interpretation of this rune is the 'womb'. So again we have this recurring theme of rebirth, a concept that well known to our pre-xtian Germanic and Celtic ancestors.
Blachetta refers to Die Doppelspirale or the double spirals as being a comparable symbol:
"The double spirals is the image-of the eternal dying and becoming-. The Ringhorn rolling itself up changes here immediately into a unrolling spiral. This symbol was very widely diffused in early cultures, especially in the Germanic Bronze Age. The often heard meaning, the double spirals portray the two courses of the sun before and after the winter solstice, is naturally only one in the great circle of events of dying and becoming." (page 62)
Just as our ancestors realised that the sun 'dies' and then is 'reborn' so it is the case with the Ich-heit (the 'self') which transcends the individual bodily incarnations which we continually experience.
