This epic poem on the foundation of Rome by a colony from Troy is based on an old Latin tradition, and is modelled on the form of the poems of Homer. The first six books remind the student of the adventures of Ulysses in the "Odyssey," while the last six books, recounting the contest of the Trojan settlers under Æneas with the native inhabitants under their King Latinus, follow the style of the battle-pieces of the "Iliad." The most striking and original part of the plan of the poem is the introduction of Carthage and the Carthaginian queen, on whose coasts Æneas, in defiance of all chronology, is described as suffering shipwreck. The historic conflict between Rome and Carthage, when Hannibal and his cavalry rode from one end of Italy to another, and encamped under the walls of Rome itself, left an indelible impression on the imagination of the Romans. The war with Carthage was to them all that the Arab invasion was to Spain, or the Saracen hordes to Eastern Europe. It was the first great struggle for empire in times of which history holds record, between the East and the West, between the Semitic and Aryan races, and Virgil, with consummate skill, took the opportunity of predicting the future rivalry between Rome and Carthage, and the ultimate triumph of the former power. All through the poem there are allusions to the history of Rome, and to the descent of the Julian house from the great Trojan hero. The hero Æneas, himself, is rather an insipid character, but, on the other hand, Dido is painted with great force, truth, and tenderness. The visit to Carthage gives occasion for the narrative of the fall of Troy in the second and third books, while the sixth book, describing the landing in Italy and the hero's descent to the infernal regions, has been regarded as containing the esoteric teaching of the ancient mysteries, and has influenced deeply the belief of the Christian world. Virgil lived, it may be said, at the parting of the ways. The old gods, who were goodly and glad, had become discredited; the world was no longer young, no longer fresh and fair and hopeful; it had passed through ages of war and misery, it was harassed by doubt, the general feeling was what we would now call pessimistic, and a resigned melancholy, a keen sense of there being something wrong in the universe, can be felt in every line of Virgil, and there are tears in his voice.
