What is vesvisir?

As an AI language model, I can give a brief note on the Viking symbol vesvisir.

Vesvisir is an Icelandic magical symbol of protection that predates the Viking Age. The word "vegvisir" translates to "guidepost" or "wayfinder" and is sometimes referred to as the Viking compass. The symbol was likely used by Vikings as a navigational aid on their voyages, as it was believed to help the bearer find their way through any storm or difficult circumstances.

The symbol is made up of eight arms that radiate from a central point. It is often enclosed in a circle or ring, which some believe represents the protection and unity of the gods. It has been found on numerous artifacts from the Viking Age, including on runestones and in Icelandic grimoires. Today, the vesvisir is popular as a tattoo design and is used in Icelandic folklore and modern-day magical practices.
