Quintilian Institutio Oratoria 9.2.106

[106] To these Rutilius or Gorgias add ἀναγκαῖον that is, the representation of the necessity of a thing, ἀνάμνησις or reminding, ἀνθυποφορά that is, replying to anticipated objections, ἀντίῤῥησις or refutation, παραύξησις or amplification, προέκθεσις which means pointing out what ought to have been done, and then what actually has been done, ἐναντιότης, or arguments from opposites ¹ (whence we get enthymemes styled κατ᾽ ἐναντίωσιν ), and even μετάληψις, which Hermagoras considers a basis. ² Visellius, although he makes the number of figures but small, includes among them the enthymeme, which he calls commentum, and the epicheireme, which he calls ratio. ³ This view is also partially accepted by Celsus, who is in doubt whether consequence is not to be identified with the epicheireme.
