In parentibus vero quam plurimum esse eruditionis optaverim, nec de patribus tantum loquor. nam Gracchorum eloquentiae multum contulisse accepimus Corneliam matrem, cuius doctissimus sermo in posteros quoque est epistulis traditus: et Laelia C. filia reddidisse in loquendo paternam elegantiam dicitur, et Hortensiae Q. filiae oratio apud triumviros habita legitur non tantum in sexus honorem. nec tamen ii, quibus discere ipsis non contigit, minorem curam docendi liberos habeant; sed sint propter hoc ipsum ad cetera magis diligentes.
(Quintilian, Inst. Or. 1.1.6-7)
As regards parents, I should like to see them as highly educated as possible, and I do not restrict this remark to fathers alone. We are told that the eloquence of the Gracchi owed much to their mother Cornelia, whose letters even to-day testify to the cultivation of her style. Laelia, the daughter of Gaius Laelius, is said to have reproduced the elegance of her father’s language in her own speech, while the oration delivered before the triumvirs by Hortensia, the daughter of Quintus Hortensius, is still read and not merely as a compliment to her sex. And even those who have not had the fortune to receive a good education should not for that reason devote less care to their son’s education; but should on the contrary show all the greater diligence in other matters where they can be of service to their children.
