Roman legionaries on a pedestal relief in the ancient Mogontiacum (now Mainz, Germany). The legionary in the foreground was shown in a fighting position: shield in readiness, protects the body; gladius ready to push; legs apart to maintain balance and the left foot without crossing the lower edge of the shield in case the legionary had to lower it to defend himself.
The object dates to the 1st century CE; is in the Romano-Germanic Central Museum.
