Disapproval of acting and the theatre was a distinguishing Roman characteristic, in the eyes of many ancient authors. The significance Romans attached to the different ways actors were viewed in Greece and in Rome is indicated by Cornelius Nepos, in the preface to his Lives, where he sets out some of the principal contrasts between Greek and Roman culture:

While Greeks admired actors, according to Nepos, to display oneself on stage, to make a spectacle of oneself, was considered by Romans to be shameful. Other writers, too, saw differing attitudes to the theatre as a significant indicator of the contrast between Greek and Roman culture.
