The rhythm is pleasing; the style simple and flowing; and if we did not possess the model we might admire the copy. The tone of exaggeration which characterises all the poetry of Nero's time mars the reality of these pastoral scenes. The author professes great reverence for Virgil, but does not despair of being coupled with him (vi. 64):
"Magna petis Corydon, si Tityrus esse laboras."
And he begs his wealthy friend Meliboeus (perhaps Seneca) to introduce his poems to the emperor (Ecl. iv. 157), and so fulfil for him the office that he who led Tityrus to Rome did for the Mantuan bard. If his vanity is somewhat excessive we must allow him the merits of a correct and pretty versifier.
The didactic poem on Aetna is now generally attributed to LUCILIUS JUNIOR, the friend and correspondent of Seneca. Scaliger printed it with Virgil's works, and others have assigned Cornelius Severus as the author, but several considerations tend to fix our choice on Lucilius. First, the poem is beyond doubt much later than the Augustan age; the constant reproduction, often unconscious, of Virgil's form of expression, implies an interval of at least a generation; allusions to Manilius [77] may be detected, and perhaps to Petronius Arbiter, [78] but at the same time it seems to have been written before the great eruption of Vesuvius (69 A.D.), in which Pliny lost his life, since no mention is made of that event. All these conditions are fulfilled by Lucilius. Moreover, he is described by Seneca as a man who by severe and conscientious study had raised his position in life (which is quite what we should imagine from reading the poem), and whose literary attainments were greatly due to Seneca's advice and care. "Assero te mihi: meum opus es," he says in one of his epistles, [79] and in another he asks him for the long promised account of a voyage round Sicily which Lucilius had made. He goes on to say, "I hope you will describe Aetna, the theme of so many poets' song. Ovid was not deterred from attempting it though Virgil had occupied the ground, nor did the success of both of these deter Cornel. Severus. If I know you Aetna excites in you the desire to write; you wish to try some great work which shall equal the fame of your predecessors." [80] As the poem further shows some resemblances to an essay on Aetna, published by Seneca himself, the conclusion is almost irresistible that Lucilius is its author.
Though by no means equal to the reputation it once had, the poem is not without merit. The diction is much less stilted than Seneca's or Persius's; the thoughts mostly correct, though rather tame; and the descriptions accurate even to tediousness. The arrangement of his subject betrays a somewhat weak hand, though in this he is superior to Gratius Faliscus; but he has an earnest desire to make truth known, and a warm interest in his theme. The opening invocation is addressed to Apollo and the Muses, asking their aid along an unwonted road.
He denies that eruptions are the work of gods or Cyclopes, and laments over the errors that the genius of poetry has spread (74-92)—
"Plurima pars scaenae fallacia."
The scenes that poets paint are rarely true, and often very hurtful, but he is moved only with the desire to discover and communicate truth. He then begins to discuss the power of confined air when striving to force a passage, and the porous nature of the interior of the earth; and (after a fine digression on the thirst for knowledge), he examines the properties of fire, and specially its effect on the different minerals composing the soil of Aetna. A disproportionate amount (nearly 150 lines) is given to describing lava, after which his theory is thus concisely summarised—
"Haec operis forma est: sic nobilis uritur Aetna:
Terra foraminibus vires trahit, urget in artum,
Spiritus incendit: vivit per maxima saxa."
The poem concludes with an account of a former eruption, signalised by the miraculous preservation of two pious youths who ventured into the burning shower to carry their parents into a place of safety. The poem is throughout a model of propriety, but deficient in poetic inspiration; the technical parts, elaborate as they are, impress the reader less favourably than the digressions, where subjects of human interest are treated, and the Roman character comes out. Lucilius called himself an Epicurean, and is so far consistent as to condemn the "fallacia vatum" and the superstition that will not recognise the sufficiency of physical causes; but he (v. 537) accepts Heraclitus's doctrine about the universality of fire, and in other places shows Stoic leanings. He imitates Lucretius's transitions, and his appeals to the reader, e.g. 160: Falleris et nondum certo tibi lumine res est, and inserts many archaisms as ulli for ullius, opus governing an accus., cremant for cremantur, auras (gen. sing.) iubar (masc.) aureus. [81] His rhythm resembles Virgil, but even more that of Manilius.
