I’m mostly interested in how the plaques can help us better understand the material world of the late republic, so the themes below are architecture, statues, rituals, spectacles, etc… But also a little of the iconography of gods that appear on coins.
Parade Scene Plaque ; very similar; fragment of similar
Circus scene: two facing quadriga, monument in middle
Hunt scene set in circus or forum ; similar depiction of spectators but details different; another full scene but almost mirror image of first ;
Theatre scene: 3 actors ; fragmentary version
armor metopes: curaiss, cross oval and square shields; another but with Macedonian shield
Colonade: two herms, two urns, boxer statue; another very similar; colonade and pediment: four athlete statues flanking a statue of Hercules; colonade: two urns and hercules statue; colonade with pediment: three athletes, one or two herms, vessel and basin on pedestal
Gallic trophy and prisoner(s?) (signed)
fragment of a scene with statue (Athena?) on column and building (round shrine?) in background
round shrine (tholos with spiral columns and metope frieze; a more complete version but with less detail in execution of architecture; similar to last; nilotic scene with spiral columns, spiral column fragment; another spiral column; and another; and another; and another; still another;
fragment of architectural detail containing volute capital

On the “Triumphal Arch, perhaps Augustus”, the animals pulling the quadriga in the middle look like sheep! Is this possible? On coins, we see chariots pulled by snakes and lions,
so why not sheep?
