When thus the prophet Helenus I hail, / "Troy-born interpreter of Heaven! whose art / the signs of Phoebus' pleasure can impart; / thou know'st the tripod and the Clarian bay, / the stars, the voices of the birds, that dart / on wings with omens laden, speak and say, / (since fate and all the gods foretell a prosperous way / and point to far Italia)."

"O Goddess-born, high auspices are thine, / and heaven's plain omens guide thee o'er the main. / Thus Jove, by lot unfolding his design, / assorts the chances, and the Fates ordain. / This much may I of many things explain, / how best o'er foreign seas to urge thy keel / in safety, and Ausonian ports attain, / the rest from Helenus the Fates conceal, / and Juno's envious power forbids me to reveal."
