Epimone

Epimone is a stylistic or rhetorical device that is particularly used in ancient Greek or Latin texts.

It describes lingering on a certain topic for longer than actually necessary by repeating the thought in another, synonymous formulation, as for example Marcus Tullius Cicero in the 1st speech against Catiline:

“Quousque tandem abutere, Catiline, patientia nostra? Quamdiu nos etiam furor iste tuus eludet? Quem ad finem sese effrenata iactabit audacia? "

“How long do you want to abuse our patience, Catilina? How much longer will this madness of yours mock us? To what point will the rampant cheek venture? "

In contrast, tautology is a repetition of thoughts without any new aspect.
