But sexuality was not excluded as a concern of the "mos maiorum", the traditional social norms that affected public, private, and military life. "Pudor", "shame, modesty", was a regulating factor in behavior, as were legal strictures on certain sexual transgressions in both the Republican and Imperial periods. The censors—public officials who determined the social rank of individuals—had the power to remove citizens from the senatorial or equestrian order for sexual misconduct, and on occasion did so. The mid-20th-century sexuality theorist Michel Foucault regarded sex throughout the Greco-Roman world as governed by restraint and the art of managing sexual pleasure.
