and judging from their own feelings, they attached a high degree of influence to the charms of poetry. Impressed with these sentiments, it became an object of importance, in their opinion, to engage the Muses in the service of the imperial authority; on which account, we find Mecaenas tampering with Propertius, and we may presume, likewise with every other rising genius in poetry, to undertake an heroic poem, of which Augustus should be the hero. As the application to Propertius cannot have taken place until after Augustus had been amply celebrated by the superior abilities of Virgil and Horace, there seems to be some reason for ascribing Mecaenas’s request to a political motive. Caius and Lucius, the emperor’s grandsons by his daughter Julia, were still living, and both young. As one of them, doubtless, was intended to succeed to the government of the empire, prudence justified the adoption of every expedient that might tend to secure a quiet succession to the heir, upon the demise of Augustus. As a subsidiary resource, therefore, the expedient above mentioned was judged highly plausible; and the Roman cabinet indulged the idea of endeavouring to confirm imperial authority by the support of poetical renown. Lampoons against the government were not uncommon even in the time of Augustus; and elegant panegyric on the emperor served to counteract their influence upon the minds of the people. The idea was, perhaps, novel in the time of Augustus; but the history of later ages affords examples of its having been adopted, under different forms of government, with success.
The Roman empire, in the time of Augustus, had attained to a prodigious magnitude; and, in his testament, he recommended to his successors never to exceed the limits which he had prescribed to its extent. On the East it stretched to the Euphrates; on the South to the cataracts of the Nile, the deserts
