There is another threefold division, whereby, it is held, we may differentiate three styles of speaking, all of them correct. The first is termed the plain [*](subtilis ( lit. = finely woven) applied to style has three meanings: (a) refined, (b) precise, (c) plain. See Sandys on Cic. Or. vi. 20. ) (or ἰσχνόν ), the second grand and forcible (or ἁδρόν ), and the third either intermediate or florid, the latter being a translation of ἀνθηρόν.
The nature of these three styles is, broadly speaking, as follows. The first would seem best adapted for instructing, the second for moving, and the third (by whichever name we call it) for charming or, as others would have it, conciliating the audience; for instruction the quality most
The intermediate style will have more frequent recourse to metaphor and will make a more attractive use of figures, while it will introduce alluring digressions, will be neat in rhythm and pleasing in its reflexions: its flow, however, will be gentle, like that of a river whose waters are clear, but overshadowed by the green banks on either side.
But he whose eloquence is like to some great torrent that rolls down rocks and
disdains a bridge[*]( Verg. Aen. viii. 728. ) and carves out its own banks for itself, will sweep the judge from his feet, struggle as he may, and force him to go whither he bears him. This is the orator that will call the dead to life (as, for example, Cicero calls upon Appius Caecus [*]( See III. viii. 54. Cicero in the pro Caclio makes both Appius Caecus and her brother Clodius address Clodia the former rebuking her for her immorality, the latter exhorting her thereto. ) ); it is in his pages that his native land itself will cry aloud and at times address the orator himself, as it addresses Cicero in the speech delivered against Catiline in the senate.
