auxesis

Figures of auxesis and repetition—often pulling together words or themes from earlier in the speech—commonly proliferate in the peroration, and many orators will crank it up a little in the direction of the grand style.

Pertaining to, or containing, auxesis; amplifying.

Auxesis, awk-sē′sis, n. gradual deepening in force of meaning: hyperbole.

And as to Horace, that Nil molitur inepte, in one Place, and——Quandoque bonus dormitat Homerus, in another, must be regarded as Hyperboles; the one as an Auxesis, the other as a Mei�sis.
