Hercules
in
The Iliad by Homer - (translated by: Pope)

The hero, when to manly years he grew, Alcides' uncle, old Licymnius, slew; For this, constrain'd to quit his native place, And shun the vengeance of the Herculean race, A fleet he built, and with a numerous train Of willing exiles wander'd o'er the main; Where, many seas and many sufferings past, On happy Rhodes the chief arrived at last: There in three tribes divides his native band, And rules them peaceful in a foreign land; Increased and prosper'd in their new abodes By mighty Jove, the sire of men and gods; With joy they saw the growing empire rise, And showers of wealth descending from the skies.†
Book 2

Tlepolemus, the sun of Hercules, Led nine swift vessels through the foamy seas, From Rhodes, with everlasting sunshine bright, Jalyssus, Lindus, and Camirus white.†
Book 2

For godlike Hercules these deeds were done, Nor seem'd the vengeance worthy such a son: When, by thy wiles induced, fierce Boreas toss'd The shipwreck'd hero on the Coan coast, Him through a thousand forms of death I bore, And sent to Argos, and his native shore.†
Book 15

Try, if the grave can hold the wanderer; If earth, at length this active prince can seize, Earth, whose strong grasp has held down Hercules.†
Book 21
