Historically, the concept of a virago reaches back into antiquity where Hellenistic philosophy asserted that elite and exceptionally heroic men had virtus. Virtus (once again linked to vir, the brave man abiding by society's highest values and ethics as opposed to homo, human being) defined the traits of excellence for a man in ancient Rome (and Greece), including valor and heroism, but also morality and physical strength. Women and non-elite or unheroic men (slaves, servants, craftsmen, merchants) were considered a lesser category, and believed to be less excellent in Roman morality.
