Engraved stele of Viking age (about 800-1000 A.D.) located at Källby, South-western Sweden. The image shows a stout figure, with a big belt around the waist and a head which seems to recall therianthropic features. One possible interpretation is that it was a representation of a bear-man, a berserk warrior, term signifying literally “bear shirt” and which alluded to an animal-skin costume. As in the case of the representations on the Torslunda plates, such a picture is associated with the tradition of Germanic warriors, who wore animal costumes or masks, meaning a ritual transformation in animals during warrior ceremonies with an ecstatic character.
