Passage: Odes 1-3 were the next focus for his artistic creativity. He adapted their forms and themes from Greek lyric poetry of the seventh and sixth centuries BC. The fragmented nature of the Greek world had enabled his literary heroes to express themselves freely and his semi-retirement from the Treasury in Rome to Horaces Villa in the Sabine hills perhaps empowered him to some extent also yet even when his lyrics touched on public affairs they reinforced the importance of private life. Nevertheless, his work in the period 30-27 BC began to show his closeness to the regime and his sensitivity to its developing ideology. In Odes 1.2, for example, he eulogized Octavian in hyperboles that echo Hellenistic court poetry. The name Augustus, which Octavian assumed in January 27 BC, is first attested in Odes 3.3 and 3.5. In the period 27-24 BC, political allusions in the Odes concentrated on foreign wars in Britain (1.35), Arabia (1.29) Spain (3.8) and Parthia (2.2). He greeted Augustus on his return to Rome in 24 BC as a beloved ruler upon whose good health he depended for his own happiness (3.14).
How many years was the period where his work showed his closeness to the regime and sensitivity to its developing ideology?
