In the fourth book Jupiter, who appears rather as contemplating the future course of affairs than as actively influencing it, speaks of Aeneas in these words:—

In the famous passage in the sixth book the mission of Rome is summed up, in contrast to the artistic glories of Greece, in the lines—
Tu regere imperio populos, Romane, memento
(Hae tibi erunt artes), pacisque inponere morem,
Parcere subiectis et debellare superbos[500].
