The still legible iconographic programme deals with military themes brought to light thanks to
recent restorations
.
On the plaster of the pillars flanking the side entrances are large rectangular paintings, two to the east and two to the west, which show traces of life-size figures. Among them are four narrower rectangular surfaces, in each of which a signum is painted, a military element carried by the centuriae in battle. The best preserved is the one located to the east, next to the right-hand
fornix
, and is distinguished by the presence of imagines, portraits inserted in a round frame, used for political or imperial propaganda.
The military theme is repeated on the frescoes that decorate the eastern wall of the square, animated by the residual colours of a procession of trotting knights, heading towards the figures at the entrance.
