“The immortal gods are wont to allow those persons whom they wish to punish for their guilt sometimes a greater prosperity and longer impunity, in order that they may suffer the more severely from a reverse of circumstances.”
Consuesse enim deos immortales, quo gravius homines ex commutatione rerum doleant, quos pro scelere eorum ulcisci velint, his secundiores interdum res et diuturniorem impunitatem concedere.
