Although the runes are Anglo-Saxon in origin, the serpent motif can be interpreted as a representation of the Norse Midgard Serpent (also called Jörmungandr or World Serpent), a central figure in Germanic mythology, which makes the shield be suitable as a Viking shield. Along with Hel and the wolf Fenrir, the Serpent is one of the three torturers in the world.
All three are children of the malicious god Loki and the giant Angrboda. Jormungand lives in the depths of the great sea that surrounds Midgard. Its body is so exceptionally large that it encircles the entire earth and grabs the end of its tail in its jaws. When he wakes up and churns up the ocean, great floods sweep through the mortal world. At the same time, the snake biting its own tail is a fruitful symbol of the unity and eternal return of all things. In the third meeting between Thor and Jörmungand at Ragnarök, Thor manages to kill the Midgard Serpent with his hammer Mjölnir.
