Institutio Oratoria

Antithesis may also be effected by employing that figure, known as ἀντιμεταβολή by which words are repeated in different cases, tenses, moods, etc., as for instance when we say, non ut edam, vivo, sed ut vivam, edo (I do not live to eat, but eat to live). There is an instance of this in Cicero, [*](pro Cluent. ii. 5. That though there is no prejudice, guilt is punished, and if there is no guilt, prejudice is laid aside. ) where he has managed, while changing the case, to secure similarity of termination: ut et sine inridia culpa plectatur et sine culpa invidia ponatur.

Again the clauses may end with the same word, as when Cicero says of Sextus Roscius: etenim cum artifex eiusmodi est ut solus videatur dignus qui in scena spectetur, turn vir eiusmodi est ut solus dignus esse videatur qui eo non accedat. [*](pro Quintio xxv. 78. For while he is an artist of such talent as to seem the only actor on the stage worth looking at, he is also a man of such character as to seem the only man worthy of being exempted from appearing on the stage. ) There is also a special elegance which may be secured by placing names in antithesis, as in the following instance, Si consul Antonius, Brutus hostis; si conservator rei publicae Brutus, hostis Antonius. [*](Phil. iv. iii. 8. "If Antony is consul, Brutus is an enemy: if Brutus is the saviour of the state, Antony is an enemy. )
