on Belisarius's wife

Let's pick up on the occasional Greek project, as begun here. The next clause of Procopius is:

αὕτη τὰ πρότερα μάχλον τινὰ βιώσασα βίον καὶ τὸν τρόπον ἐξερρωγυῖα

I might make that:

( She, formerly... )

Dewing translates it as:

( This woman... )

Literally, in the Greek she broke the path or destroyed the standard way of acting. Does anyone have a better English idiom for translation?
