The Black Sun-Wheel

The Black Sun (Schwarze Sonnenrad) literally means  'Black Sun-wheel' 

Is an ancient Aryan symbol that dates back to before the Iron Age in Europe and has been found etched on archaeological artefacts across both Germanic and Celtic countries.

The Black Sun symbolise the energy of the universe, a powerful balance between light and darkness, the turning of the Sun and the seasons of the year.

It is a form of Sun-wheel which incorporates 12 radial 'Sig' runes.

They are run rays it it a reversed whirling sun its meaning is thus: "to roll back the advance of corrupt influence and slavery of human soul from lies and deceit and a return to the oldways"
The number twelve also has relevance within Norse mythology. There are twelve Aesir gods, for example. Important groups of twelve can be found in other cultures as well, such as the Twelve Olympian Gods in Greek Mythology.

The Black Sun it is also an ancient European esoteric sign of the Norse Runes. The runes are an ancient alphabet that originated in Germanic and Scandinavian countries. Today, they are used in divination by many Pagans. According to the Norse Mythology, God Odin was the one responsible for the runes becoming available to mankind.

The true origin of the Black Sun symbol, in the archaeological record, is likely to be some time before the Migration Age (1st millennium BCE) in Eurasia, as we know that the Alamanni, Goths and other Germanic tribes with both a western and and eastern presence at the time, made bronze brooches with a similar sunwheel design. These ornamental disks, or Ziercheiben, were found in Alemannic women's graves in Germany. The significance of these symbols in women's graves of the period is not lost on people who understand one of the Sonnenrad's major meanings: the Black Sun is in one sense a womb, the mother of all things, the darkness from which creation emerges. In a theosophical sense, the Black Sun symbolizes the gigantic Black Hole at our Galaxy's center, which is indeed the mother of the galaxy, for by its gravity waves and magnetic waves spinning the gas into a spiral, it triggers eddies of star formation, literally birthing entire systems. Yet there is also a chaotic and destructive side to the Black Sun, as getting too close (literally, too oft attached) can result in being torn apart. This understanding of the primal feminine energy was integral to the Cult of Nerthus, for much as this primal Goddess of the Depths gives, she also takes away.

This however was not the only meaning of the Black Sun, nor perhaps even the foremost. Nor was it considered a symbol of femininity in an overt sense, as lunar symbols sometimes were in the Nordic-Slavic centers in Kievan Rus, but in this aspect, more of a primal energy of the creative mother which is a sort of supernatural archetype of vitality for women to seek out. Yet because it is also a solar symbol, and thus a manifestation of primal fire (Fa), it also has a strong masculine creative aspect of which the female wearers of these brooches were also aware. For it is Odin's fire-whisk and Thor's thunder-cross manifested threefold. A man embodying both the Odinic (commanding and beguiling) and Thoric (purely dominant) essences was their ideal man, the ideal singularity of strength around which the Black Sun can rotate. This is a fundamental truth of traditional societies, and of genetics.

The sun-wheel itself has been represented in many different forms throughout the Indo-European experience. One thing that can be agreed on, is that many ancient cultures began as solar cultures before later incorporating lunar and planetary symbols into their lore. The Sonnenrad can therefore be seen as a primal manifestation of solar symbols stretching back into the prehistory of the Aryan mind.
