Marcus Aurelius seems to have been about eighteen years of age when the correspondence begins, Fronto being some thirty years older.[[16]] The systematic education of the young prince seems to have been finisht, and Pronto now acts more as his adviser than his tutor. He recommends the prince to use simplicity in his public speeches, and to avoid affectation.[[17]] Marcus devotes his attention to the old authors who then had a great vogue at Rome: Ennius, Plautus, Nævius, and such orators as Cato and Gracchus.[[18]] Pronto urges on him the study of Cicero, whose letters, he says, are all worth reading.

[16] From internal evidence: the letters are not arranged in order of time. See Naher's Prolegomena, p. xx. foll.

When he wishes to compliment Marcus he declares one or other of his letters has the true Tullian ring. Marcus gives his nights to reading when he ought to be sleeping. He exercises himself in verse composition and on rhetorical themes.

'It is very nice of you,' he writes to Fronto,[[19]] 'to ask for my hexameters; I would have sent them at once if I had them by me. The fact is my secretary, Anicetus-you know who I mean-did not pack up any of my compositions for me to take away with me. He knows my weakness; he was afraid that if I got hold of them I might, as usual, make smoke of them. However, there was no fear for the hexameters. I must confess the truth to my master: I love them. I study at night, since the day is taken up with the theatre. I am weary of an evening, and sleepy in the daylight, and so I don't do much. Yet I have made extracts from sixty books, five volumes of them, in these latter days. But when you read remember that the "sixty" includes plays of Novius, and farces, and some little speeches of Scipio; don't be too much startled at the number. You remember your Polemon; but I pray you do not remember Horace, who has died with Pollio as far as I am concerned.[[20]] Farewell, my dearest and most affectionate friend, most distinguished consul and my beloved master, whom I have not seen these two years. Those who say two months, count the days. Shall I ever see you again?'

[19] Ad M. Caes., ii. 10.

[20] He implies, as in i. 6, that he has ceased to study Horace.

Sometimes Fronto sends him a theme to work up, as thus: 'M. Lucilius tribune of the people violently throws into prison a free Roman citizen, against the opinion of his colleagues who demand his release. For this act he is branded by the censor. Analyse the case, and then take both sides in turn, attacking and defending.'[[21]] Or again: 'A Roman consul, doffing his state robe, dons the gauntlet and kills a lion amongst the young men at the Quinquatrus in full view of the people of Rome. Denunciation before the censors.'[[22]] The prince has a fair knowledge of Greek, and quotes from Homer, Plato, Euripides, but for some reason Fronto dissuaded him from this study.[[23]] His Meditations are written in Greek. He continued his literary studies throughout his life, and after he became emperor we still find him asking his adviser for copies of Cicero's Letters, by which he hopes to improve his vocabulary.[[24]] Pronto helps him with a supply of similes, which, it seems, he did not think of readily. It is to be feared that the fount of Marcus's eloquence was pumped up by artificial means.

[21] Pollio was a grammarian, who taught Marcus.
