 This book shows greater poetic confidence after the public performance of his "Carmen saeculare" or "Century hymn" at a public festival orchestrated by Augustus.In it, Horace addresses the emperor Augustus directly with more confidence and proclaims his power to grant poetic immortality to those he praises.It is the least philosophical collection of his verses, excepting the twelfth ode, addressed to the dead Virgil as if he were living.
