A grove stood in the city, rich in shade, / where storm-tost Tyrians, past the perilous brine, / dug from the ground, by royal Juno's aid, / a war-steed's head, to far-off days a sign / that wealth and prowess should adorn the line.

Lashed into foam, behind them roars the brine; / now, gliding onward to the beach, ere long / they gain the fields, and rolling bloodshot eyne / that blaze with fire, the monsters move along, / and lick their hissing jaws, and dart a flickering tongue.

Scarce now the summer had begun, when straight / my father, old Anchises, gave command / to spread our canvas and to trust to Fate. / Weeping, I leave my native port, the land, / the fields where once the Trojan towers did stand, / and, homeless, launch upon the boundless brine, / heart-broken outcast, with an exiled band, / comrades, and son, and household gods divine, / and the great Gods of Troy, the guardians of our line.
