The body of the history is only a long narrative, and as such it must go on with a soft and even motion, alike in every part, so that nothing should stand too forward, or retreat too far behind.
ἅπαν γὰρ ἀτεχνῶς τὸ λοιπὸν σῶμα τῆς ἱστορίας διήγησις μακρά ἐστιν. ὥστε ταῖς τῆς διηγήσεως ἀρεταῖς κατακεκοσμήσθω, λείως τε καὶ ὁμαλῶς προϊοῦσα καὶ αὑτῇ ὁμοίως ὥστε μὴ προὔχειν μήτε κοιλαίνεσθαι.
