Dialogus de ōrātōribus (‘dialogue on orators’), dialogue attributed to Tacitus and now generally accepted as by him, in spite of differences in style from his later work, which may be the result of its belonging to a different literary genre. It is no longer thought to be an early work; since it is dedicated to Lucius Fabius Justus, consul in AD 102, it was probably published in that year or soon after. The claims of oratory against other branches of literature are discussed, and the reasons why oratory has declined since Cicero's day. The scene is set in the house of Curiātius Māternus, a poet. The other interlocutors are two distinguished orators, Marcus Aper, an advocate, and Julius Secundus, both of Gallic birth and both teachers of Tacitus; and Vipstanus Messalla, a man of distinguished birth. The date is supposed to be c.AD 75. The first twenty-seven chapters are introductory. Aper, a practical, utilitarian lawyer, maintains the superiority of oratory over poetry, for the rewards it brings. Maternus, a meditative idealist, disdains wealth and power and prefers a quiet life and the companionship of the Muses. Aper admits no decline in oratory. Messalla, a champion of former times, criticizes the modern speakers. At the request of Maternus he passes to the causes of the alleged decline (ch. 28), which for the purposes of the discussion is to be assumed. These causes Messalla finds in the lax education of the young, contrasted with the careful methods of former days; and in the defective training given to orators in the schools of rhetoric. After this there is a gap of several pages in the manuscript. When the text resumes someone else (probably Maternus) is speaking. He argues that the decline in oratory is due to the changed conditions of public life. Oratory flourished under the republic in times of disorder and revolution, when orators were inspired by political enthusiasm. The calmness of political life under the emperors has removed these incentives, but has brought compensations.
Oratory was seen by Tacitus to be in an inevitable decline, linked as it was to political institutions themselves in decline. It is interesting to compare this work with the near-contemporary Education of an Orator (published in the 90s) by Quintilian, whose concern is rather with the technical and literary aspects of oratory.
