Chances are good that you have seen the name Thor in a comic book. Or maybe you have seen one of the movies that also bear this famous name. Without a doubt the Norse god of thunder has experienced a surge in popularity in recent years. But he is actually much older than either the men who have played him or the people who have drawn him. Norse mythology became known throughout Europe thanks to a group of brutal warriors called the Vikings. As they traveled from Scandinavia through Europe, the Vikings shared their stories—the basis for their religion—with others. And along with his father Odin and his rival Loki, Thor became known throughout the rest of the world as well.
