Cicero (2.3-2.4)

And although he showed himself, as Plato[*] thought a nature should do which was fond of learning and fond of wisdom, capable of welcoming all knowledge and incapable of slighting any kind of literature or training, he lent himself with somewhat greater ardour to the art of poetry. And a little poem which he wrote when a boy is still extant, called Pontius Glaucus, and composed in tetrameter verse. Moreover, as he grew older and applied himself with greater versatility to such accomplishments, he got the name of being not only the best orator, but also the best poet among the Romans.

His fame for oratory abides to this day, although there have been great innovations in style; but his poetry, since many gifted poets have followed him, has altogether fallen into neglect and disrepute.
