Quintilian, Inst. Orat. 10.1
“Atacinus Varro acquired his name as a translator of other’s work—he certainly shouldn’t be dismissed, but in truth he has little to commend for improving an ability in speaking. Ennius, we should adore as we would groves sacred with age whose ancient trees have less beauty than they have religious awe. Others are closer to this time and are more useful for our subject. Ovid is certainly indulgent in his epic verse and too in love with his own genius, but still should be praised for some things. Cornelius Severus, moreover, even if he was a better metrician than a poet, still would have claimed second place for himself if he had finished his Sicilian War to the standard of his first book.
An early death kept Serranus from reaching his potential, yet his youthful works demonstrate special ability and a desire for correct form that is especially admirable in one so young. We recently lost a lot in Valerius Flaccus. Saleius Bassus had a forceful poetic ability—it did not improve with age. Rabirius and Pedo are worth a read, if you have extra time. Lucan is forceful, intense, and famous for his quotability, but, if I may say what I really think, a model more for orators than poets.
I am listing these authors because care for the lands of the earth has distracted Germanicus Augustus [Domitian] from the pursuits he began—it seemed insufficient to the gods that he be the greatest of poets. But, still, what could appear more sublime, more learned, and more outstanding by every account than the works of this young man who put the empire aside? Who could sing of wars better than the one who wages them in this way? Whom would the deities of these arts heed more closely? To whom would Minerva more easily unveil her own arts? Future generations will explain these things more fully, for now this praise is constrained by the glare of his other virtues.”
Atacinus Varro in iis per quae nomen est adsecutus interpres operis alieni, non spernendus quidem, verum ad augendam facultatem dicendi parum locuples. Ennium sicut sacros vetustate lucos adoremus, in quibus grandia et antiqua robora iam non tantam habent speciem quantam religionem. Propiores alii atque ad hoc de quo loquimur magis utiles. Lascivus quidem in herois quoque Ovidius et nimium amator ingenii sui, laudandus tamen partibus. Cornelius autem Severus, etiam si sit versificator quam poeta melior, si tamen (ut est dictum) ad exemplar primi libri bellum Siculum perscripsisset, vindicaret sibi iure secundum locum. Serranum consummari mors inmatura non passa est, puerilia tamen eius opera et maximam indolem ostendunt et admirabilem praecipue in aetate illa recti generis voluntatem. Multum in Valerio Flacco nuper amisimus. Vehemens et poeticum ingenium Salei Bassi fuit, nec ipsum senectute maturuit. Rabirius ac Pedo non indigni cognitione, si vacet. Lucanus ardens et concitatus et sententiis clarissimus et, ut dicam quod sentio, magis oratoribus quam poetis imitandus. Hos nominamus quia Germanicum Augustum ab institutis studiis deflexit cura terrarum, parumque dis visum est esse eum maximum poetarum. Quid tamen his ipsis eius operibus in quae donato imperio iuvenis secesserat sublimius, doctius, omnibus denique numeris praestantius? Quis enim caneret bella melius quam qui sic gerit? Quem praesidentes studiis deae propius audirent? Cui magis suas artis aperiret familiare numen Minerva? Dicent haec plenius futura saecula, nunc enim ceterarum fulgore virtutum laus ista praestringitur. Nos tamen sacra litterarum colentis feres, Caesar, si non tacitum hoc praeterimus et Vergiliano certe versu testamur
