The lower scene, in which the figures are less readily identifiable, depicts the erection of a "tropaion". In some interpretations of the scene, all the lower figures are by design anonymous. Other interpretations attribute definite real or mythological persons to the figures. At left, the seated male and female figures (combined in #11) are either Celts or Germans, as is apparent from their clothing and hair styles, including the man's beard, and represent prisoners of war, symbolizing the Roman victory. The man is bound with his hands behind his back, and both are apparently about to be tied to the base of the as yet half-erected "tropaion" (figure #19), a trophy of war displayed upon winning a battle, usually fixed into the ground at the position of the "turning-point" of the battle in favour of the victors. The trophy consists of a wooden cross, designed to support human clothing. A helmet is placed on top, and the breastplate and weaponry of the enemy is placed upon it. In the scene, four young men are raising the trophy into a vertical position. Figure #18 is the least identifiable, but his helmet has led some to believe that he may be a Macedonian soldier of King Rhoemetalces I, who helped Tiberius in Pannonia.
