Petrarch, Epistulae Familiares 4.15:
“It is difficult to say how much re-reading your letter two or three times soothed my ears, which were so worn down by the noise of the rabble. Even if this letter seemed verbose to you (as I learned from its ending), I find nothing to accuse you of but terseness. And so, I looked on the final threat, in which you claimed that you would write more briefly in the future, with unwilling eyes. I would have you be more prolix. As you will – you’re the father. It is right for me to accommodate my ways to you, and not the other way around. But will the whole business not be in your hands? Or do you not know that quite often the actual event differs from the plan? Perhaps you will hear what forces even one who is eager for silence to talk. You want me to fulfill the threats which I seem to be making now?
I stand as a witness, in the first place, that I have the same opinion of you which Macrobius had of Aristotle (whether it be love or the truth which gave rise to it). That is, I hardly think that you could not know something. If something has slipped your lips which seems to be contrary to the truth, I suspect that you either have not thought it out far enough, or just as Macrobius says of Aristotle, I suspect that you are playing around.”
Dictu difficile est quantum aures meas, vulgari fessas strepitu, epystola tua bis terque relecta permulserit; que quanquam tibi verbosa videretur, ut ex fine cognovi, ego tamen in ea nil preter breviloquium accusavi. Itaque comminationem illam ultimam, quod deinceps compendiosior sis futurus, invitus aspexi; mallem prolixior. Ut libet tamen; tu pater; non te michi, sed me tibi morem gerere dignum est. Sed ita ne totum in tua manu positum erit? an ignoras quod sepe consilio dissimilis est eventus? Audies forte quod vel silentii avidum loqui cogat. Vis quod minitari videor, iam nunc rebus impleam?
Testor in primis eandem me de te opinionem gerere, quam de Aristotile Macrobius, seu illam amor, seu veritas genuerit: vix te aliquid “ignorare posse” arbitror; siquid autem vero adversum tibi excidit, aut minus providisse aut, quod de eodem ait idem, lusisse te suspicor.
