In this noblest of Epistles Horace has been warning Quinctius to trust his own judgement about his happiness—is he sapiens bonusque? (20). The plaudits of the people are fickle and can be withdrawn overnight. Only a man who is flawed and in need of treatment is delighted by false honour or upset by untrue defamation: the philosophic man is impervious to both. Horace, prompted by the words ‘pone, meum est’, illustrates the idea of defamation by reference to a very ancient and traditional form of Italian popular justice—flagitatio ordefamatory dunning.The three charges made in the Horatian passage—thieving, homosexuality, and unfilial behaviour—also appear in the classic Plautine catalogue of flagitatio at Pseud. 360 ff., where the pimp Ballio is abused: ‘fur’ (365), ‘impudice’ (360), ‘parricida’ (362).
