This is the Norse protection symbol called Vegvísir. Icelandic word: ‘guidepost’;‘direction sign’. In modern popular culture often called Runic Compass or See the Way. This symbol is from the 17th century Icelandic grimoire called Galdrabók (‘magic book’). The origin of this type of witchcraft is difficult to ascertain: to some extent it derives from medieval mysticism and renaissance occultism. Vegvísir was drawn on one’s forehead with blood to prevent a person from getting lost.
