Reliquaries often imaged the objects that they contained.  The head of St. Oswold (605-42) was acquired by the cathedral of Hildesheim, Germany.  A reliquary (1170-90) was created to image the head of the first Christian King of Northumbria (Northern England). Just below the head, on the eight sides of the reliquary are the four evangelists and the four rivers of paradise.  On the lowest level are plaques showing Oswald and other sainted rulers.
