It was the dramatic productions of the Greeks which were first studied and copied at Rome. Livius Andronicus, Nævius, Ennius, Plautus, and Terence, all of whom wrote under the republic, are the most noted of the Roman dramatists. Most of their plays were simply adaptations or translations of Greek masterpieces. Lucilius (born 148 B.C.) was one of the greatest of Roman satirists. The later satirists of the corrupt imperial era were his imitators. Besides Lucilius, there appeared during the later republican era only two other poets of distinguished merit, Lucretius and Catullus. Lucretius (95-51 B.C.) was an evolutionist, and in his great poem, _On the Nature of Things_, we find anticipated many of the conclusions of modern scientists. POETS OF THE AUGUSTAN AGE.--We have in another place (see p. 307) spoken of the effects of the fall of the republic upon the development of Latin literature. Many, who if the republican institutions had continued would have been absorbed in the affairs of state, were led, by the change of government, to seek solace for their disappointed hopes, and employment for their enforced leisure, in the graceful labors of elegant composition. Four names have cast an unfading lustre over the period covered by the reign of Augustus, Virgil, Horace, Ovid, and Livy. So distinguished have these writers rendered the age in which they lived, that any period in a people's literature marked by unusual literary taste and refinement is called, in allusion to the Roman era, an _Augustan Age_. Of the three poets, Virgil, Horace, and Ovid, a word has already been said; of Livy we shall find place to say something a little later, under the head of the Roman historians. SATIRE AND SATIRISTS.--Satire thrives best in the reeking soil and tainted atmosphere of an age of selfishness, immorality, and vice. Such an age was that which followed the Augustan era at Rome. The throne was held by such imperial monsters as Caligula, Nero, and Domitian. The profligacy of fashionable life at the capital and the various watering-places of the empire, and the degradation of the court gave venom and point to the shafts of those who were goaded by the spectacle into attacking the immoralities and vices which were silently yet rapidly sapping the foundations of both society and state. Hence arose a succession of writers whose mastery of sharp and stinging satire has caused their productions to become the models of all subsequent attempts in the same species of literature. Two names stand out in special prominence--Persius and Juvenal, who lived and wrote during the last half of the first and the beginning of the second century of our era.
