Yet this long period, in which poetry, with so much difficulty and such scanty resources, struggled into existence at Rome, is connected with the age of Cicero by an unbroken line of literary continuity. Naevius, the younger contemporary of Livius, and the first native poet, was actively engaged in the composition of his poems till the time of his death; about which period his greater successor first appeared at Rome. For about thirty years, Ennius shone alone in epic and tragic poetry. The poetic successor of Ennius was his nephew, Pacuvius. He, in the later years of his life, lived in friendly intercourse with his younger rival Accius, who, again, in his old age, had frequently conversed with Cicero[4]. The torch, which was first lighted by Livius Andronicus from the decaying fires of Greece, was thus handed down by these few men, through this long period, until it was extinguished during the stormy times which fell in the youth of the great orator and prose writer of the Republic. The forms of serious poetry, prevailing during this period, were the tragic drama, the annalistic epic, and satire. Tragedy was earliest introduced, was received with most favour, and was cultivated by all the poets of the period, with the exception of Lucilius and the comic writers. The epic poetry of the age was the work of Naevius and Ennius. It has greater claims to originality and national spirit, both in form and substance, and it exercised a more powerful influence on the later poetry of Rome, than either the tragedy or comedy of the time. The invention of satire, the most purely original of the three, is generally attributed to Lucilius; but the satiric spirit was shown earlier in some of the dramas of Naevius; and the first modification of the primitive satura to a literary shape was the work of Ennius, who was followed in the same style by his nephew Pacuvius.
