Part of Viking mythology is that Odin, the most revered of all the Gods. Sacrificed himself by hanging upside down for nine days and nights impaled by his own spear from the legendary yggdrasil or world tree to gain spiritual knowledge. He returned with the secrets of the runes.
The runic symbols were used for writing and magic by priests and shaman to guide the Norsemen on their travels and into battle. Both the Saxons and the Celts are known to have used runes for shamanistic purposes and they are used today as a tool for prophecy and guidance. Crystal balls have a long history and reputation for mystical power Celtic Druids are reputed to have used crystals in divination many seers, wizards, gypsies, fortune tellers, and all other types of diviners also used crystals to "see" into the past, present, or future also known as "scrying," images are seen in crystals, and interpreted by the seer.
