And note, besides, that liquor of honey or milk
Yields in the mouth agreeable taste to tongue,
Whilst nauseous wormwood, pungent centaury,
With their foul flavour set the lips awry;
Thus simple 'tis to see that whatsoever
Can touch the senses pleasingly are made
Of smooth and rounded elements, whilst those
Which seem the bitter and the sharp, are held
Entwined by elements more crook'd, and so
Are wont to tear their ways into our senses,
And rend our body as they enter in.
In short all good to sense, all bad to touch,
Being up-built of figures so unlike,
Are mutually at strife--lest thou suppose
That the shrill rasping of a squeaking saw
Consists of elements as smooth as song
Which, waked by nimble fingers, on the strings
The sweet musicians fashion; or suppose
That same-shaped atoms through men's nostrils pierce
When foul cadavers burn, as when the stage
Is with Cilician saffron sprinkled fresh,
And the altar near exhales Panchaean scent;
Or hold as of like seed the goodly hues
Of things which feast our eyes, as those which sting
Against the smarting pupil and draw tears,
Or show, with gruesome aspect, grim and vile.
For never a shape which charms our sense was made
Without some elemental smoothness; whilst
Whate'er is harsh and irksome has been framed
Still with some roughness in its elements.
Some, too, there are which justly are supposed
To be nor smooth nor altogether hooked,
With bended barbs, but slightly angled-out,
To tickle rather than to wound the sense--
And of which sort is the salt tartar of wine
And flavours of the gummed elecampane.
Again, that glowing fire and icy rime
Are fanged with teeth unlike whereby to sting
Our body's sense, the touch of each gives proof.
For touch--by sacred majesties of Gods! --
Touch is indeed the body's only sense--
Be't that something in-from-outward works,
Be't that something in the body born
Wounds, or delighteth as it passes out
Along the procreant paths of Aphrodite;
Or be't the seeds by some collision whirl
Disordered in the body and confound
By tumult and confusion all the sense--
As thou mayst find, if haply with the hand
Thyself thou strike thy body's any part.
On which account, the elemental forms
Must differ widely, as enabled thus
To cause diverse sensations.

And, again,
What seems to us the hardened and condensed
Must be of atoms among themselves more hooked,
Be held compacted deep within, as 'twere
By branch-like atoms--of which sort the chief
Are diamond stones, despisers of all blows,
And stalwart flint and strength of solid iron,
And brazen bars, which, budging hard in locks,
Do grate and scream. But what are liquid, formed
Of fluid body, they indeed must be
Of elements more smooth and round--because
Their globules severally will not cohere:
To suck the poppy-seeds from palm of hand
Is quite as easy as drinking water down,
And they, once struck, roll like unto the same.
But that thou seest among the things that flow
Some bitter, as the brine of ocean is,
Is not the least a marvel. . .
For since 'tis fluid, smooth its atoms are
And round, with painful rough ones mixed therein;
Yet need not these be held together hooked:
In fact, though rough, they're globular besides,
Able at once to roll, and rasp the sense.
And that the more thou mayst believe me here,
That with smooth elements are mixed the rough
(Whence Neptune's salt astringent body comes),
There is a means to separate the twain,
And thereupon dividedly to see
How the sweet water, after filtering through
So often underground, flows freshened forth
Into some hollow; for it leaves above
The primal germs of nauseating brine,
Since cling the rough more readily in earth.
Lastly, whatso thou markest to disperse
Upon the instant--smoke, and cloud, and flame--
Must not (even though not all of smooth and round)
Be yet co-linked with atoms intertwined,
That thus they can, without together cleaving,
So pierce our body and so bore the rocks.
Whatever we see. . .
Given to senses, that thou must perceive
They're not from linked but pointed elements.

The which now having taught, I will go on
To bind thereto a fact to this allied
And drawing from this its proof: these primal germs
Vary, yet only with finite tale of shapes.
For were these shapes quite infinite, some seeds
Would have a body of infinite increase.
For in one seed, in one small frame of any,
The shapes can't vary from one another much.
Assume, we'll say, that of three minim parts
Consist the primal bodies, or add a few:
When, now, by placing all these parts of one
At top and bottom, changing lefts and rights,
Thou hast with every kind of shift found out
What the aspect of shape of its whole body
Each new arrangement gives, for what remains,
If thou percase wouldst vary its old shapes,
New parts must then be added; follows next,
If thou percase wouldst vary still its shapes,
That by like logic each arrangement still
Requires its increment of other parts.
Ergo, an augmentation of its frame
Follows upon each novelty of forms.
Wherefore, it cannot be thou'lt undertake
That seeds have infinite differences in form,
Lest thus thou forcest some indeed to be
Of an immeasurable immensity--
Which I have taught above cannot be proved.

And now for thee barbaric robes, and gleam
Of Meliboean purple, touched with dye
Of the Thessalian shell. . .
The peacock's golden generations, stained
With spotted gaieties, would lie o'erthrown
By some new colour of new things more bright;
The odour of myrrh and savours of honey despised;
The swan's old lyric, and Apollo's hymns,
Once modulated on the many chords,
Would likewise sink o'ermastered and be mute:
For, lo, a somewhat, finer than the rest,
Would be arising evermore. So, too,
Into some baser part might all retire,
Even as we said to better might they come:
For, lo, a somewhat, loathlier than the rest
To nostrils, ears, and eyes, and taste of tongue,
Would then, by reasoning reversed, be there.
