Segmental armor of the "Alba Julia" type in Dacia of the 3rd century. In this scene, the legionnaires resist the attack of the Goths in front of the praetorium gate of the fortress of Apulum, in order to give the returning patrol time to get to safety. They are commanded by the highest centurion Primus Pilus, who wears muscular armor in recognition of his newly acquired status as a Roman Knight (-here in the sense of social class).
