The Dialogus de oratoribus is a short work attributed to Tacitus, in dialogue form, on the art of rhetoric.
Maternus thinks that great oratory was possible with the freedom from any power, more precisely in the anarchy, that characterized the Roman Republic during the civil wars.
The peace, warranted by the Empire, should be accepted without regret for a previous age that was more favorable to the wide spread of literacy and the growth of great personality.
Nevertheless, Tacitus does not accept the imperial government apathetically, and he shows, as in the Agricola the remaining possibility of making choices that are dignified and useful to the state.
The way of speaking in the Dialogus seems closer to the model of Cicero, refined but not prolix, which inspired the teaching of Quintilian; it lacks the incongruities that are typical of Tacitus's major historical works.
