A parazonium is a long triangular dagger, wide at the hilt end and coming to a point. In Roman iconography, it is frequently carried by Virtus, particularly in early representations of the deity, Mars, and Dea Roma, as well as the emperor, military tribunes and other senior officers, giving them the aura of courage.
