[Footnote 6: Horace had doubtless seen not only the Culex but several of the other minor works that Vergil never deigned to put into general circulation.]
The influences that made for classicism were many. Apollodorus, the teacher of Octavian, must have been a strong factor, but since his work has been lost, the weight of it cannot now be estimated. Horace imbibed his love for severe ideals in Athens, of course. There his teachers were Stoic rhetoricians who trained him in an uncompromising respect for stylistic rules.[7] He read the Hellenistic poets, to be sure, and reveals in his poems a ready memory of them, but it was the great epoch of Greek poetry that formed his style. Such are the foreign influences. But the native Roman factors must not be forgotten. In point of fact it was the classicistic Catullus and Calvus, of the simple, limpid lyrics, written in pure unalloyed every-day Latin, that taught the new generation to reject the later Hellenistic style of Catullus and Calvus as illustrated in the verse romances. Varus, Pollio, and Varius were old enough to know Catullus and Calvus personally, to remember the days when poems like Dianae sumus in fide were just issued, and they were poets who could value the perfect art of such work even after the authors of them had been enticed by ambition into dangerous by-paths. In a word, it was Catullus and Calvus, the lyric poets, who made it possible for the next generation to reject Catullus and Calvus the neoteric romancers.
