Imaginifer
Imaginifer (Latin: Imaginifer) was a type of standard-bearer in the Roman army who carried the likeness of the emperor into battle. This served as a constant reminder of the soldiers' loyalty to the emperor. This variety of standard-bearer emerged in the legions after the cult of the emperor was established during the reign of Octavian Augustus. The "imago" was a three-dimensional portrait made of colored metal, which was carried alongside the aquila exclusively in the first cohort.

Bust of an imago found in Avenshae. AD 161-180The distinctive feature of the imaginifer was the bear or wolf skin worn over the helmet, with the paws tied around the neck. Their armament consisted of a gladius (sword) and pugio (dagger). As protective equipment, imaginifers used either lorica hamata (chainmail) or lorica squamata (scale armor), as well as a small round shield called a parma, which they carried on a strap at their side.
