Dragons are viewed as representing the primal forces in nature and the universe. They can alternately breathe fire, poison, or ice. These abilities demonstrate that they are both creators and destroyers and symbolize chaos and order.
The Mjolnir (Thor’s hammer) one of the most iconic and powerful symbols was certainly a weapon but It also occupied a central role in rituals of consecration and hallowing. The hammer was used in formal ceremonies to bless marriages, births, and funerals as well.
