Lucretius, De Rerum Natura
William Ellery Leonard, Ed.

     And to whate'er pursuit
A man most clings absorbed, or what the affairs
On which we theretofore have tarried much,
And mind hath strained upon the more, we seem
In sleep not rarely to go at the same.
The lawyers seem to plead and cite decrees,
Commanders they to fight and go at frays,
Sailors to live in combat with the winds,
And we ourselves indeed to make this book,
And still to seek the nature of the world
And set it down, when once discovered, here
In these my country's leaves. Thus all pursuits,
All arts in general seem in sleeps to mock
And master the minds of men. And whosoever
Day after day for long to games have given
Attention undivided, still they keep
(As oft we note), even when they've ceased to grasp
Those games with their own senses, open paths
Within the mind wherethrough the idol-films
Of just those games can come. And thus it is
For many a day thereafter those appear
Floating before the eyes, that even awake
They think they view the dancers moving round
Their supple limbs, and catch with both the ears
The liquid song of harp and speaking chords,
And view the same assembly on the seats,
And manifold bright glories of the stage-
So great the influence of pursuit and zest,
And of the affairs wherein 'thas been the wont
Of men to be engaged-nor only men,
But soothly all the animals. Behold,
Thou'lt see the sturdy horses, though outstretched,
Yet sweating in their sleep, and panting ever,
And straining utmost strength, as if for prize,
As if, with barriers opened now...
And hounds of huntsmen oft in soft repose
Yet toss asudden all their legs about,
And growl and bark, and with their nostrils sniff
The winds again, again, as though indeed
They'd caught the scented foot-prints of wild beasts,
And, even when wakened, often they pursue
The phantom images of stags, as though
They did perceive them fleeing on before,
Until the illusion's shaken off and dogs
Come to themselves again. And fawning breed
Of house-bred whelps do feel the sudden urge
To shake their bodies and start from off the ground,
As if beholding stranger-visages.
And ever the fiercer be the stock, the more
In sleep the same is ever bound to rage.
But flee the divers tribes of birds and vex
With sudden wings by night the groves of gods,
When in their gentle slumbers they have dreamed
Of hawks in chase, aswooping on for fight.
Again, the minds of mortals which perform
With mighty motions mighty enterprises,
Often in sleep will do and dare the same
In manner like. Kings take the towns by storm,
Succumb to capture, battle on the field,
Raise a wild cry as if their throats were cut
Even then and there. And many wrestle on
And groan with pains, and fill all regions round
With mighty cries and wild, as if then gnawed
By fangs of panther or of lion fierce.
Many amid their slumbers talk about
Their mighty enterprises, and have often
Enough become the proof of their own crimes.
Many meet death; many, as if headlong
From lofty mountains tumbling down to earth
With all their frame, are frenzied in their fright;
And after sleep, as if still mad in mind,
They scarce come to, confounded as they are
By ferment of their frame. The thirsty man,
Likewise, he sits beside delightful spring
Or river and gulpeth down with gaping throat
Nigh the whole stream. And oft the innocent young,
By sleep o'ermastered, think they lift their dress
By pail or public jordan and then void
The water filtered down their frame entire
And drench the Babylonian coverlets,
Magnificently bright. Again, those males
Into the surging channels of whose years
Now first has passed the seed (engendered
Within their members by the ripened days)
Are in their sleep confronted from without
By idol-images of some fair form-
Tidings of glorious face and lovely bloom,
Which stir and goad the regions turgid now
With seed abundant; so that, as it were
With all the matter acted duly out,
They pour the billows of a potent stream
And stain their garment.
