The Seafarer, Ezra Pound (based upon the Anglo-Saxon poem of the same title).

May I for my own self song's truth reckon,

Journey's jargon, how I in harsh days

Hardship endured oft.

Bitter breast-cares have I abided,

Known on my keel many a care's hold,

And dire sea-surge, and there I oft spent

Narrow nightwatch nigh the ship's head

While she tossed close to cliffs. Coldly afflicted,

My feet were by frost benumbed.

Chill its chains are; chafing sighs

Hew my heart round and hunger begot

Mere-weary mood. Lest man know not

That he on dry land loveliest liveth,

List how I, care-wretched, on ice-cold sea,

Weathered the winter, wretched outcast

Deprived of my kinsmen;

Hung with hard ice-flakes, where hail-scur flew,

There I heard naught save the harsh sea

And ice-cold wave, at whiles the swan cries,

Did for my games the gannet's clamour,

Sea-fowls, loudness was for me laughter,

The mews' singing all my mead-drink.

Storms, on the stone-cliffs beaten, fell on the stern

In icy feathers; full oft the eagle screamed

With spray on his pinion.

Not any protector

May make merry man faring needy.

This he little believes, who aye in winsome life

Abides 'mid burghers some heavy business,

Wealthy and wine-flushed, how I weary oft

Must bide above brine.

Neareth nightshade, snoweth from north,

Frost froze the land, hail fell on earth then

Corn of the coldest. Nathless there knocketh now

The heart's thought that I on high streams

The salt-wavy tumult traverse alone.

Moaneth alway my mind's lust

That I fare forth, that I afar hence

Seek out a foreign fastness.

For this there's no mood-lofty man over earth's midst,

Not though he be given his good, but will have in his youth greed;

Nor his deed to the daring, nor his king to the faithful

But shall have his sorrow for sea-fare

Whatever his lord will.

He hath not heart for harping, nor in ring-having

Nor winsomeness to wife, nor world's delight

Nor any whit else save the wave's slash,

Yet longing comes upon him to fare forth on the water.

Bosque taketh blossom, cometh beauty of berries,

Fields to fairness, land fares brisker,

All this admonisheth man eager of mood,

The heart turns to travel so that he then thinks

On flood-ways to be far departing.

Cuckoo calleth with gloomy crying,

He singeth summerward, bodeth sorrow,

The bitter heart's blood. Burgher knows not --

He the prosperous man -- what some perform

Where wandering them widest draweth.

So that but now my heart burst from my breast-lock,

My mood 'mid the mere-flood,

Over the whale's acre, would wander wide.

On earth's shelter cometh oft to me,

Eager and ready, the crying lone-flyer,

Whets for the whale-path the heart irresistibly,

O'er tracks of ocean; seeing that anyhow

My lord deems to me this dead life

On loan and on land, I believe not

That any earth-weal eternal standeth

Save there be somewhat calamitous

That, ere a man's tide go, turn it to twain.

Disease or oldness or sword-hate

Beats out the breath from doom-gripped body.

And for this, every earl whatever, for those speaking after --

Laud of the living, boasteth some last word,

That he will work ere he pass onward,

Frame on the fair earth 'gainst foes his malice,

Daring ado, ...

So that all men shall honour him after

And his laud beyond them remain 'mid the English,

Aye, for ever, a lasting life's-blast,

Delight mid the doughty.

Days little durable,

And all arrogance of earthen riches,

There come now no kings nor Cæsars

Nor gold-giving lords like those gone.

Howe'er in mirth most magnified,

Whoe'er lived in life most lordliest,

Drear all this excellence, delights undurable!

Waneth the watch, but the world holdeth.

Tomb hideth trouble. The blade is layed low.

Earthly glory ageth and seareth.

No man at all going the earth's gait,

But age fares against him, his face paleth,

Grey-haired he groaneth, knows gone companions,

Lordly men are to earth o'ergiven,

Nor may he then the flesh-cover, whose life ceaseth,

Nor eat the sweet nor feel the sorry,

Nor stir hand nor think in mid heart,

And though he strew the grave with gold,

His born brothers, their buried bodies

Be an unlikely treasure hoard. 

The Seafarer, Ezra Pound, 1911, based upon the Anglo-Saxon poem of the same title, which gives a first-person account of a man alone on the sea. Recorded only in the Exeter Book, the Old English poem is one of the four surviving manuscripts of Old English poetry.

Short extract on the nature of heroes from J.R.R. Tolkien's Beowulf: The Monsters and the Critics, 1936.

The significance of a myth is not easily to be pinned on paper by analytical reasoning. It is at its best when it is presented by a poet who feels rather than makes explicit what his theme portends; who presents it incarnate in the world of history and geography, as our poet has done [referring to anonymous author of Beowulf]. Its defender is thus at a disadvantage: unless he is careful, and speaks in parables, he will kill what he is studying by vivisection, and he will be left with a formal or mechanical allegory, and what is more, probably with one that will not work. For myth is alive at once and in all its parts, and dies before it can be dissected. It is possible, I think, to be moved by the power of myth and yet to misunderstand the sensation, to ascribe it wholly to something else ( that is also present: to metrical art, style, or verbal skill. Correct and sober taste my refuse to admit that there can be an interest for usthe proud we that includes all intelligent living people-in ogres and dragons; We then perceive its puzzlement in face of the odd fact that it has derived great pleasure from a poem that is actually about these unfashionable creatures. Even though it attributes 'genius',

It does not seem plain that ancient taste supports the modern as much as it has been represented to do. I have the author of Beowulf, at any rate, on my side: a greater man than most of us. And I cannot myself perceive a period in the North when one kind alone was esteemed: there was room for myth and heroic legend, and for blends of these. As for the dragon: as far as we know anything about these old poets, we know this: the prince of the heroes of the North, supremely memorable - hans nafn mun uppi, meðan veröldin stendr* - was a dragon-slayer. And his most renowned deed, from which in Norse he derived his title Fafnisbani, was the slaying of the prince of legendary worms. Although there is plainly considerable difference between the later Norse and the ancient English form of the story alluded to in Beowulf, already there it had these two primary features: the dragon, and the slaying of him as the chief deed of the greatest of heroes - he wres wreccena wide mrerost**. A dragon is no idle fancy. Whatever may be his origins, in fact or invention, the dragon in legend is a potent creation of men's imagination, richer in significance than his barrow is in gold.
...

Beowulf's dragon, if one wishes really to criticize, is not to be blamed for being a dragon, but rather for not being dragon enough, plain pure fairy-story dragon. There are in the poem some vivid touches of the right kind - as Pa se wynn onwoc, wroht wees geniwad stone refter stane*** - in which this dragon is real worm, with a bestial life and thought of his own, but the conception, none the less, approaches draconitas rather than draco: a personification of malice, greed, destruction (the evil side of heroic life), and of the l undiscriminating cruelty of fortune that distinguishes not good or , bad (the evil aspect of all life). But for Beowulf, the poem, that is as it should be. In this poem the balance is nice, but it is preserved. The large sybolism is near the surface but it does not break through, nor become allegory. Something more significant than a standard hero, a man faced with a foe more evil than any human enemy of house or realm, is before us, and yet incarnate in time, walking in heroic history, and treading the named lands of the North. And this, we are told, is the radical defect of Beowulf, that its author, coming in a time rich in the legends of heroic men, has used them afresh in an original fashion, giving us not just one more, but something akin yet different: a measure and interpretation of them all. We do not deny the worth of the hero by accepting Grendel and the dragon. Let us by all means esteem the old heroes: men caught in the chains of circumstance or of their own character, torn between duties equally sacred, dying with their backs to the wall. But Beowulf, I fancy, plays a larger part than is recognized in helping us to esteem them.

...

When we have read his poem, as a poem, rather than as a collection of episodes, we perceive that he who wrote hafað under heofonum may have meant in dictionary terms 'heroes under heaven', or 'mighty men upon earth', but he and his hearers were thinking of the eormengrund, the great earth, ringed with garsecg, the shoreless sea, beneath the sky's inaccessible roof; whereon, as in a little circle of light about their halls, men with courage as their stay went forward to that battle with the hostile world and the offspring of the dark which ends for all, even the kings and champions, in defeat. That even this 'geography', once held as a material fact, could now be classed as a mere folk-tale affects its value very little. It transcends astronomy.
