Livy, Ab Urbe Condita, Praefatio 9
“But these tales and those like them—whether to ponder them or how to weigh them—I don’t emphasize greatly. Let anyone who reads these instead pay attention to what life was like, what the customs were, through which men and by which skills the empire was born and increased. And, when discipline bit by bit deteriorated, how at first customs degraded with desire, then they collapsed more and more, then they began to fall headlong until we came to our own time when we can endure neither our sins nor their remedies.”
ad haec tempora quibus nec vitia nostra nec remedia pati possumus. Sed haec et his similia utcumque animaduersa aut existimata erunt haud in magno equidem ponam discrimine: ad illa mihi pro se quisque acriter intendat animum, quae vita, qui mores fuerint, per quos viros quibusque artibus domi militiaeque et partum et auctum imperium sit; labente deinde paulatim disciplina velut desidentes primo mores sequatur animo, deinde ut magis magisque lapsi sint, tum ire coeperint praecipites, donec ad haec tempora quibus nec vitia nostra nec remedia pati possumus perventum est.
