"Would that your king AEneas here could stand, / driven by the gale that drove you to this strand! / Natheless, to scour the country, will I send / some trusty messengers, with strict command / to search through Libya to the furthest end, / lest, cast ashore, through town or lonely wood he wend."

"Then, but for folly or Fate's adverse power, / his word had made us with our trusty glaive / lay bare the Argive ambush, and this hour / should Ilion stand, and thou, O Priam's lofty tower!"
