'Virtue' ( virtus) was seen as an active quality through which a man ( vir) defined himself. Roman society was patriarchal, and the freeborn male citizen possessed political liberty ( libertas) and the right to rule both himself and his household ( familia). The primary dichotomy of ancient Roman sexuality was active/ dominant/masculine and passive/submissive/feminine. Latin lacks words that would precisely translate ' homosexual' and ' heterosexual'. Homosexuality in ancient Rome often differs markedly from the contemporary West. Roman mosaic from Susa, Libya, depicting the myth of Zeus in the form of an eagle abducting the boy Ganymede
