Three vast areas in northern Europe during the Roman Period are known for their people’s development of a distinctive viewpoint regarding the riding horse that was reflected in sacrificial rites (north Germany; the Jutland Peninsula; Zealand, Funen, other Baltic Sea islands, as well as southern Scandinavia) and burial rites (Dollkeim-Kovrovo, Sudovian, West Lithuanian Stone Circle Grave cultures, and, in part, the Lower Nemunas and Bogaczewo cultures). The custom at the end of the second century and in the third century to bury a riding horse (usually only the horse’s head, head and legs, or individual teeth) with armed men was especially distinct in the West Lithuanian Stone Circle Grave Culture area. This burial rite feature distinguishes the mentioned cultural unit (Aistians) area from the communities of other Balts who lived in current Lithuanian territory. The burial rite features that had developed in the West Lithuanian Stone Circle Grave Culture area illustrate the warriors’ hierarchy and the military’s dependency on the society’s nobility that already existed in the Roman Period. These social structure features link the West Balt communities with the northern Germanic peoples. West Lithuanian Stone Circle Grave Culture was the northernmost barbaricum territory in which riding horses were so often buried with people.
