Virtus was a specific virtue in ancient Rome. It carried connotations of valor, manliness, excellence, courage, character, and worth, perceived as masculine strengths (from Latin vir, "man"). Virtus applied exclusively to a man's behavior in the public sphere, that is to the application of duty to the res publica in the cursus honorum. Private business was no place to earn virtus, even when it involved courage or feats of arms or other good qualities. There could be no virtue in exploiting one's manliness in the pursuit of personal wealth, for example. It was thus a frequently stated virtue of Roman emperors and was personified as the deity Virtus. Virtus is depicted as a helmeted soldier, often a female, in armor holding a spear, parazonium, victory or a shield. Virtus and Mars can be distinguished since Mars is usually shown nude and Virtus is always shown clothed.
