"O fortunati quorum jam moenia surgunt," he cries as he looks on the rising walls of Carthage. His gloom has been lightened indeed by the assurance of his fame which he gathers from the pictures of the great Defence graven on the walls of the Tyrian temple. But the loneliness and longing still press heavily on him when the cloud which has wrapt him from sight parts suddenly asunder, and Dido and Æneas stand face to face. Few situations in poetry are more artistic than this meeting of Æneas and the Queen in its suddenness and picturesqueness. A love born of pity speaks in the first words of the hero,[6] and the reply of Dido strikes the same sympathetic note.[7] But the fervour of passion is soon to supersede this compassionate regard. Love himself in the most exquisite episode of the Æneid takes the place of Ascanius; while the Trojan boy lies sleeping on Ida, lapped on Earth's bosom beneath the cool mountain shade, his divine "double" lies clasped to Dido's breast, and pours his fiery longings into her heart. Slowly, unconsciously, the lovers draw together. The gratitude of Æneas is still at first subordinate to his quest. "Thy name and praise shall live," he says to Dido, "whatever lands call me." In the same way, though the Queen's generosity has shown itself in her first offer to the sailors ("urbem quam statuo vestra est"), it is still generosity and not passion. Passion is born in the long night through which, with Eros still folded in her arms, Dido listens to the "Tale of Troy." The very verse quickens with the new pulse of love. The preface of the Æneid, the stately introduction that fortells the destinies of Rome and the divine end to which the fates were guiding Æneas, closes in fact with the appearance of Dido. The poem takes a gayer and lighter tone. The disguise and recognition of Venus as she appears to her son, the busy scene of city-building, the sudden revelation of Æneas to the Queen, have the note of exquisite romance. The honey-sweet of the lover's tale, to use the poet's own simile,[8] steals subtly on the graver epic. Step by step Vergil leads us on through every stage of pity, of fancy, of reverie, of restlessness, of passion, to the fatal close. None before him had painted the thousand delicate shades of love's advance; none has painted them more tenderly, more exquisitely since. As the Queen listens to the tale of her lover's escape she showers her questions as one that could never know enough. "Multa super Priamo rogitans, super Hectore multa."
