Institutio Oratoria

Again in legal cases of minor importance a similar simplicity will be found to be most becoming, a simplicity, that is to say, that does not dispense with rhythm altogether, but uses rhythms of a different kind, conceals them and employs a certain secrecy in their construction.

But the more closely welded style is composed of three elements: the comma, or as we call it incisum, the colon, or in Latin menbrum, and the period, [*]( See § 122; comma, colon, period, now applied to stops, originally referred to varying lengths of clauses or sentences. ) which Roman writers call ambitus, circumductum, continuatio or conclusio. Further, in all artistic structure there are three necessary qualities, order, connexion and rhythm.
