The chapter endeavours to extend the search for politeness rituals in non-literary sources where some dialogue interaction is represented. Significant dialogic interaction is preserved in Roman juridical texts, a source hitherto neglected in studies of ancient politeness. Transcripts of political meetings, of magistrates’ and emperors’ hearings and, above all, of court sessions have been preserved both in papyrus documents and in medieval manuscripts; they enable scholars to widen their knowledge of the forms of linguistic interaction in court debate beyond the little that is known anecdotically about Roman advocacy, and also to observe the evolution of politeness formulae across time.
