 Before the historical significance of runestones and picture stones was understood, they were often reused as materials in the construction of roads, bridges, walls, and buildings.The image on the stone illustrates a legend recorded in the "Hymiskviða" of the "Poetic Edda", in which the Norse god Thor fishes for Jörmungandr, the Midgard serpent.Thor goes fishing with the jötunn Hymir using an ox head for bait, and catches Jörmungandr, who then either breaks loose or, as told in the "Gylfaginning" of the "Prose Edda", the line is cut loose by Hymir.
