"We who have followed o'er the billowy brine / thee and thine arms, since Ilion sank in flame, / will raise thy children to the stars, and name / thy walls imperial. Thou build them meet / for heroes. Shrink not from thy journey's aim, / though long the way."

Far off is seen, above the billowy mere, / Trinacrian AEtna, and the distant roar / of ocean and the beaten rocks we hear, / and the loud burst of breakers on the shore; / high from the shallows leap the surges hoar, / and surf and sand mix eddying.
