Lucretius, De Rerum Natura
William Ellery Leonard, Ed.

     But nature 'twas
Urged men to utter various sounds of tongue
And need and use did mould the names of things,
About in same wise as the lack-speech years
Compel young children unto gesturings,
Making them point with finger here and there
At what's before them. For each creature feels
By instinct to what use to put his powers.
Ere yet the bull-calf's scarce begotten horns
Project above his brows, with them he 'gins
Enraged to butt and savagely to thrust.
But whelps of panthers and the lion's cubs
With claws and paws and bites are at the fray
Already, when their teeth and claws be scarce
As yet engendered. So again, we see
All breeds of winged creatures trust to wings
And from their fledgling pinions seek to get
A fluttering assistance. Thus, to think
That in those days some man apportioned round
To things their names, and that from him men learned
Their first nomenclature, is foolery.
For why could he mark everything by words
And utter the various sounds of tongue, what time
The rest may be supposed powerless
To do the same? And, if the rest had not
Already one with other used words,
Whence was implanted in the teacher, then,
Fore-knowledge of their use, and whence was given
To him alone primordial faculty
To know and see in mind what 'twas he willed?
Besides, one only man could scarce subdue
An overmastered multitude to choose
To get by heart his names of things. A task
Not easy 'tis in any wise to teach
And to persuade the deaf concerning what
'Tis needful for to do. For ne'er would they
Allow, nor ne'er in anywise endure
Perpetual vain dingdong in their ears
Of spoken sounds unheard before. And what,
At last, in this affair so wondrous is,
That human race (in whom a voice and tongue
Were now in vigour) should by divers words
Denote its objects, as each divers sense
Might prompt?- since even the speechless herds, aye, since
The very generations of wild beasts
Are wont dissimilar and divers sounds
To rouse from in them, when there's fear or pain,
And when they burst with joys. And this, forsooth,
'Tis thine to know from plainest facts: when first
Huge flabby jowls of mad Molossian hounds,
Baring their hard white teeth, begin to snarl,
They threaten, with infuriate lips peeled back,
In sounds far other than with which they bark
And fill with voices all the regions round.
And when with fondling tongue they start to lick
Their puppies, or do toss them round with paws,
Feigning with gentle bites to gape and snap,
They fawn with yelps of voice far other then
Than when, alone within the house, they bay,
Or whimpering slink with cringing sides from blows.
Again the neighing of the horse, is that
Not seen to differ likewise, when the stud
In buoyant flower of his young years raves,
Goaded by winged Love, amongst the mares,
And when with widening nostrils out he snorts
The call to battle, and when haply he
Whinnies at times with terror-quaking limbs?
Lastly, the flying race, the dappled birds,
Hawks, ospreys, sea-gulls, searching food and life
Amid the ocean billows in the brine,
Utter at other times far other cries
Than when they fight for food, or with their prey
Struggle and strain. And birds there are which change
With changing weather their own raucous songs-
As long-lived generations of the crows
Or flocks of rooks, when they be said to cry
For rain and water and to call at times
For winds and gales. Ergo, if divers moods
Compel the brutes, though speechless evermore,
To send forth divers sounds, O truly then
How much more likely 'twere that mortal men
In those days could with many a different sound
Denote each separate thing.
