We now possess parts of his correspondence with Antoninus Pius, with M. Aurelius, with L. Verus, and with certain of his friends, and also several rhetorical and historical fragments. Though none of the more ambitious works of Fronto have survived, there are enough to give proof of his powers. Never was a great literary reputation less deserved. It would be hard to conceive of anything more vapid than the style and conception of these letters; clearly the man was a pedant without imagination or taste. Such indeed was the age he lived in, and it is no marvel that he was like to his age. But there must have been more in him than mere pedantry; there was indeed a heart in the man, which Marcus found, and he found also a tongue which could speak the truth. Fronto's letters are by no means free from exaggeration and laudation, but they do not show that loathsome flattery which filled the Roman court. He really admires what he praises, and his way of saying so is not unlike what often passes for criticism at the present day. He is not afraid to reprove what he thinks amiss; and the astonishment of Marcus at this will prove, if proof were needed, that he was not used to plain dealing. "How happy I am," he writes, "that my friend Marcus Cornelius, so distinguished as an orator and so noble as a man, thinks me worth praising and blaming."[3] In another place he deems himself blest because Pronto had taught him to speak the truth[4] although the context shows him to be speaking of expression, it is still a point in favour of Pronto. A sincere heart is better than literary taste; and if Fronto had not done his duty by the young prince, it is not easy to understand the friendship which remained between them up to the last.
