Swastika as nazi symbol was different to ancient swastika or wheel, constated in India, Mesopotamia, Egypt... This last was disposed from left to wright, meaning the eternal mouvement, the seasons cycles and renovation of life, so a powerful and sacred symbol.
Nazi's one was inverted(from right to left). This sign inverted means the rupture of cycles, the destruction and of course the bad luck. any inverted swastica was seen before if not in black practises. It would be interesting to see which swastika Alix was devoted. Any dessign or paper exists belonging to her?
