The stones are dated as being carved after 934 C.E. as the historian Widukind of Corvey recorded that King Gnupa, who is mentioned in both inscriptions, was forced to pay a tribute to the German king in that year.[2]
DR 2
DR 2 was found at Haddeby in Schleswig-Holstein in 1797. At one time, scholars considered the word and rune selection on this runestone, when compared with the inscription on DR 4, along with other inscriptions as evidence of Swedish influence in Denmark during the 10th century.[2] For example, although both DR 2 and DR 4 use the Younger Futhark, DR 2 uses "short twig" style runes for the n- and a-runes.[3] However, in recent years this has been downplayed after it was shown that part of the evidence was actually due to a misdating of another runestone and the possible misspellings of some words in the inscriptions.[2]
DR 4 was discovered in 1887 on the ramparts of Gottorf Castle.[2] Prior to the recognition of the historical significance of runestones, they were often used as construction materials for roads, walls, and buildings.
