From Alfred, Lord Tennyson's "Ulysses"

 

There lies the port; the vessel puffs her sail;
There gloom the dark, broad seas. My mariners,
Souls that have toiled, and wrought, and thought with me---
That ever with a frolic welcome took

The thunder and the sunshine, and opposed
Free hearts, free foreheads---you and I are old;
Old age hath yet his honor and his toil.
Death closes all; but something ere the end,
Some work of noble note, may yet be done,
Not unbecoming men that strove with gods.
The lights begin to twinkle from the rocks;
The long day wanes; the slow moon climbs; the deep
Moans round with many voices. Come, my friends.
'Tis not too late to seek a newer world.
Push off, and sitting well in order smite
the sounding furrows; for my purpose holds
To sail beyond the sunset, and the baths
Of all the western stars, until I die.
It may be that the gulfs will wash us down;
It may be that we shall touch the Happy Isles,
And see the great Achilles, whom we knew.
Though much is taken, much abides; and though
We are not now that strength which in old days
Moved earth and heaven, that which we are,

we are--One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.
