The Vegvísir is a magical symbol that guides people during a day of bad weather. It is related to an artifact (solar compass) used by Viking navigators, similar to the compass rose. This symbol appears in an Icelandic book of magic, or grimoire known as Galdrabók, published around 1600. The Aegishjalmur or ægishjálmur (Old Norse: ægishjálmr) meaning "Ægir's helmet", is a magical symbol of protection used by the Vikings. Of Icelandic origin, it is also known as a spell of terror or fear. These types of symbols were commonly used by Viking warriors as a protective sign painted on the front before battle, known as herkumbl (“sign of war”). Drawn between the eyes, it was given the ability to make the wearer invincible and terrify their enemies. He appears in several Norse sagas, where he is referred to by various names as a semblance of terror or a dominant character.
