Vegvisir is most commonly known as the Viking Compass , Runic Compass is a symbol of protection and direction believed to have been used by Vikings as a compass. In Icelandic, vegvisir means "wayfinder" and "sign post." It is made of eight staves.
Two sources mention the Vegvisir: the Huld Manuscript by Geir Vigfusson and The Galdrabok, a textbook for magic (grimoire)
In the Huld Manuscript, the Vegvisir is a symbol of guidance and protection “the wearer of this symbol will not lose his way during storms and bad weather, even if he does not know his destination”.
The other historical reference to Vegvisir is the Galdrabok, a spell book which provides knowledge of magic, cosmology, astrology and the Germanic religion and gods.
In this grimoire it says that the Vegvisir symbol would help its wearer not to be lost and to find their way back. It says that the Vegvisir must be drawn in fresh blood on a Viking's forehead. This is similar to how the Aegishjalmur (known as the Helm of Awe) would be used.
While Vegvisir and Aegishjalmr, the helm of awe are superficially similar, they are very different Viking symbols.
It is believed by some that Vegvisir Viking Compass was used for navigation across the seas.
If so the eight Icelandic rune lines would correspond to the main directions (North, South, West, East) and middle directions (Northwest, Northeast, Southwest, Southeast).
In fact archaeologists have shown that the Vikings used a "sunstone" which was a sun compass of sorts on their voyages.
There are also historical mentions of Vegvisir Viking compass being drawn, etched or burned onto the side of Viking ships to give them protection and bring them home safely.
Today many people of Nordic origin and beyond find inspiration from the Viking symbol as a sign of protection and a guide to find one's way through life.
The Viking Compass (Vegvisir) is probably the most "differently" or maybe mis-spelled Viking symbol. Variations we have seen include Vegisvir, Vigvisir, Vegisir, Vegvisor, Vegwisir, Vegvesir, Vegvisit and Vegvisr.
