Leaping ritual dancers?
In Swedish rock carvings we see the shields being used in religious rites. Although shields are normally regarded as part of weaponry, there is no doubt that the rock carvings show that shields are being used in a ritual context. On the ship in the rock carving in Hede, for example, we see two men holding a shield and almost dancing with it. Alongside the shield-bearers we see acrobatic dancers. Perhaps the shields were used as sun symbols?
