The Vegvísir, ("The Guide Post" in Icelandic) called “Wegweiser” in German language, which literally translates into Direction-Guide, is often also known as Runic Compass. This symbol is originally from the 17th Century, taken out of an Icelandic Grimoire, called the GALDRABÒK, according to some Germanic Scripts, it has been drawn on peoples foreheads, so that they will not get lost during Journeys and, most importantly, rough and heavy weather. A page in the original HULD Manuscript says that once the person wears that magical Sigil, the person will never get lost during storms and weather.
Some people argue that one can see the directional markings of N, NE, E, SE, S, SW, W, NW.
Today, we have two known navigational Sun Compass used by the Vikings. The first known archaeological Compass has 32 marks and was discovered in Greenland in 1947. And the other one in Poland in 2000. Both date around 1000, the Viking Age was between 800 and 1300.
In Hrafn’s Saga, it has been said that the Vikings navigated by the use of a Sun stone, that was perhaps optical calcite with its polarizing effects even during bad weather.
The Vegvisir is basically a magical Sigil, used for protection and navigation through Storms, bad weather and can be also seen as a protection Sigil against negative forces and powers. Not much is known today about Galdr and Seidr, so I will refuse to make any speculations and projections… as this hurts the bits of knowledge more than anything else.
The known Ægishjálmur is another Symbol with Icelandic Heritage and the spiritual practice of Galdr.
Here a short insight into the Manuscript.
