The best known of these, Tängelgårda I, includes scenes that have been interpreted in terms of the cult of Odin.
The stones were found together at a site in Lärbro parish, and are believed to have been re-used to enclose a grave.
The four stones were discovered in the 1860s at Fånggården, near the farm of Tängelgårda, in Lärbro parish on Gotland, and removed to the Swedish History Museum.
[3][4] The largest and best known of the group, Tängelgårda I is a five-panel tall stone variously dated to 400–550 CE,[5] the 8th century,[6] or the Viking Age, between 800 and 1100.
[6] This fourth panel has been interpreted as a hero and his followers being welcomed into Valhalla, and related specifically to the legend of Sigurd.
