Lucian Pseudologista 13

[13] The custom was introduced among different peoples in different ways; either they were defeated in great battles and subsequently established that those days on which they had undergone such misfortunes should be useless and invalid for their customary transactions, or, indeed—but it is inopportune, perhaps, and by now unseasonable to try to alter an old man’s education and reinstruct him in such matters when he does not know even what precedes them. ¹ It can hardly be that this is all that remains, and that if you learn it, we shall have you fully informed! Nonsense, man! Not to know those other expressions which are off the beaten path and obscure to ordinary folk is pardonable; but even if you wished, you could not say nefandous in any other way, for that is everyone’s sole and only word for it.
