The wounded boar is being attacked by a lion and a leopard which are being followed by rows of lions and leopards. A battle scene is portrayed on another ornamented belt, where men with lances are fighting with rapier carriers. A high-ranking captive is being escorted by a garrison. The next scene in the centre is a “feast.” The king is portrayed sitting on the throne and drinking. A servant with “hoof-like legs” is standing between the tables in front of the king and serving him. Next to the king musicians are seen.
