Like everyone else, I was brought up to repeat that regnauit populorum is a ‘Greek genitive = ’ If one shrinks from depriving examinationpapers of this interesting idiom, he may be consoled by remembering that abstineto irarum and desine querelarum are still left. Why should not populorum depend in a normal manner upon potens (cf. diua potens Cypri) ? Surely the sense is improved by the antithesis pauper aquae, potens agrestium populorum. ‘Where Daunus, scant of water, ruled rustic peoples’ contains a somewhat cold pedantry, which is at least partially relieved by the fuller description. I find it difficult to understand why so many scholars prefer to make ex humili potens refer to Horace himself.
