Thor's Hammer : MJOLNIR - video
The Thor's Hammer or Hammer of Thor is an ancient Norse symbol. In Norse mythology, Thor is the god of thunder and his hammer (called Mjölnir) has the power of lightning.
During the era of Viking ascendancy, miniature Thor's Hammers were often used as religious amulets. Today, the Hammer is a major symbol for those who follow neo-Norse religions such as Asatru.
