With the landing in Italy the narrative assumes greater independence. The various localities introduced and the traditions connected with them, the usages or ceremonies peculiar to Italy which admit of being referred to an immemorial past, the mere Italian names of Latinus and Turnus, Mezentius and Camilla, are able to evoke national and sometimes modern associations. Thus the introduction of the Cumaean Sibyl into the narrative affords the opportunity of reminding the Romans of the importance assigned to the Sibylline prophecies in their national counsels; and the impressive ceremony of the opening of the gates of war enables the poet to appeal to the patriotic impulses of his own age, in the lines--
Sive Getis inferre manu lacrimabile bellum Hyrcanisve Arabisve parant, seu tendere ad Indos Auroramque sequi Parthosque reposcere signa(491).
But many of the warlike incidents in the later books--as for instance the night foray of Nisus and Euryalus, the treacherous wounding of Aeneas, the withdrawal by supernatural agency of Turnus from the battle, the death of Pallas and the effect which that event has on Aeneas, and the final conflict between Turnus and Aeneas--show that Virgil was still following in the footsteps of his original guide. The passages, however, which bring out most clearly both this relation of Virgil to Homer and his point of departure from him are those which give an account of the descent into hell and describe the shield of Aeneas. The sixth book of the Aeneid owes its existence to the eleventh book of the Odyssey: but the shadowy conceptions of the Homeric 'Inferno,' suggested by the impulses of natural curiosity and the yearnings of human affection, are enlarged and made more definite, on the one hand, by thoughts derived from Plato, and, on the other, by the proudest memories of Roman history, from the legends of the Alban kings to the warlike and peaceful triumphs of the Augustan Age. The shield of Achilles presents to the imagination the varied spectacle of human life--sowing and reaping, a city besieged, a marriage festival, etc.; the shield of Aeneas presents the spectacle of the most momentous crises in the annals of Rome, culminating in the great triumph of Augustus. We note too in the latter passage the enhancement of patriotic sentiment by the use of the language and representation of Ennius, as at lines 630-634, and the lesson taught of the dependence of national welfare on the observance of religious traditions and of the duties of life sanctioned by religion, in the lines which describe the processions of the Salii and Luperci, and which indicate the punishment awarded to the sin of rebellion and disloyalty in the person of Catiline, and the recognition of civic virtue, even when exercised in defence of a losing cause, in the position assigned to Cato in the nether world--
