To the Vikings, shields were more than just a piece of equipment used in battle. They were also an important part of their spiritual beliefs. In Norse mythology, shields were associated with the god Tyr, who was the patron deity of warriors.
Tyr was said to have sacrificed his right hand in order to bind the Fenris Wolf, and his symbol was often carved onto Viking shields. In addition to being a symbol of courage and strength, shields also represented protection from harm.
They were believed to possess magical properties that could deflect enemy weapons and safeguard the bearer from harm. As such, shields played a vital role in the spiritual beliefs of the Vikings.
