[1] It depicts three soldiers in high relief in the foreground, while two others in the background, accompanied by a standard bearer, are made in bas-relief.

The soldiers have been identified as Praetorians due to the richness of the apparel, particularly the helmets, the ceremonial dress and oval shields.

[4] The Praetorians Relief was once part of the Arch of Claudius, erected in AD 51 to commemorate the conquest of Britain.

The head of the standard-bearer is depicted in Album by Jacques d'Angoulême [fr] of Reims, on the page dated to 1577.
