"Monitus multumque monendus Privatas ut quaerat opes, et tangere vitet Scripta Palatinus quaecunque recepit Apollo." [83] The last of these friends we shall notice is JULUS ANTONIUS [84] a son of the triumvir, who, according to Acron, [85] wrote twelve excellent books in epic metre on the legends of Diomed, a work obviously modelled on those of Euphorion, whose fourteen books of _Heracleia_ were extremely popular; in a later age Statius attempted a similar task in essaying the history of Achilles. The ode addressed to him by Horace seems to hint at a foolish ambition to imitate Pindar. Besides these lesser known authors Horace knew, though he does not mention, the poets Ovid and Domitius Marsus; probably also Propertius. With Tibullus he was long on terms of friendship, and one epistle and one ode [86] are addressed to him. His gentle nature endeared him to Horace, as his graceful poetry drew forth his commendation. CHAPTER IV. THE ELEGIAC POETS--GRATIUS--MANILIUS. The short artificial elegy of Callimachus and Philetas had, as we have seen, found an imitator in Catullus. But that poet, when he addressed to Lesbia the language of true passion, wrote for the most part in lyric verse. The Augustan age furnishes a series of brilliant poets who united the artificial elegiac with the expression of real feeling; and one of them, Ovid, has by his exquisite formal polish raised the Latin elegiac couplet to a popularity unparalleled in imitative literature. The metre had at first been adapted to short epigrams modelled on the Greek, _e.g._, triumphal inscriptions, epitaphs, _jeux d'esprit_, &c., several examples of which have been quoted in these pages. Catullus and his contemporaries first treated it at greater length, and paved the way for the highly specialised form in which it appears in Tibullus, the earliest Augustan author that has come down to us.
