Institutio Oratoria

such as arrangement, distinction by headings, and circumscription, whether this latter term be intended to signify the concise expression of thought or definition, which is actually regarded by Cornificius and Rutilius as a figure of speech. With regard to the elegant transposition of words, that is, hyperbaton, which Caecilius also thinks is a figure, I have included it among tropes. As for mutation [*](Immutatio in Cicero (IX. i. 35) seems to mean metonymy or ὑπαλλαγή (see Orator, xxvii. 92): The ἀλλοίωσις of Rutilius (i. 2) is however differentiation. )

of the kind which Rutilius calls ἀλλοίωσις its function is to point out the differences between men, things and deeds: if it is used on an extended scale, it is not a figure, if on a narrower scale, it is mere antithesis, while if it is intended to mean hypallage, enough has already been said on the subject.
