Norse mythology contains many symbols. It is virtually impossible to understand the Nordic faith without a proper understanding of the Nordic symbols and their meanings. Hulinhjalmur is one of the most famous symbols of the Vikings, protecting them from enemies by making them invisible. As a result, this magic cane contributed to the tall, muscular, courageous and widespread fear character of the Vikings, especially in battles. It is a mark that was painted on the forehead to make it invisible.
