Quintilian Institutio Oratoria 8.6.65

[65] When, however, the transposition is confined to two words only, it is called anastrophe, that is, a reversal of order. This occurs in everyday speech in mecum and secure, while in orators and historians we meet with it in the phrase quibus de rebus. It is the transposition of a word to some distance from its original place, in order to secure an ornamental effect, that is strictly called hyperbaton: the following passage will provide an example: animadverti, indices, omnem accusatoris orationenm in duas divisam esse partes. ¹ ( ) In this case the strictly correct order would be in duas partes divisam esse, but this would have been harsh and ugly.
