De Rerum Natura

For the light breeze that hovers yet can blow

High heaps of poppy-seed away for thee

Downward from off the top; but, contrariwise,

A pile of stones or spiny ears of wheat

It can't at all. Thus, in so far as bodies

Are small and smooth, is their mobility;

But, contrariwise, the heavier and more rough,

The more immovable they prove. Now, then,

Since nature of mind is movable so much,

Consist it must of seeds exceeding small

And smooth and round. Which fact once known to thee,

Good friend, will serve thee opportune in else.

This also shows the nature of the same,

How nice its texture, in how small a space

'Twould go, if once compacted as a pellet:

When death's unvexed repose gets hold on man

And mind and soul retire, thou markest there

From the whole body nothing ta'en in form,

Nothing in weight. Death grants ye everything,

But vital sense and exhalation hot.

Thus soul entire must be of smallmost seeds,

Twined through the veins, the vitals, and the thews,

Seeing that, when 'tis from whole body gone,

The outward figuration of the limbs

Is unimpaired and weight fails not a whit.

Just so, when vanished the bouquet of wine,

Or when an unguent's perfume delicate

Into the winds away departs, or when

From any body savour's gone, yet still

The thing itself seems minished naught to eyes,

Thereby, nor aught abstracted from its weight-

No marvel, because seeds many and minute

Produce the savours and the redolence

In the whole body of the things.

And so,

Again, again, nature of mind and soul

'Tis thine to know created is of seeds

The tiniest ever, since at flying-forth

It beareth nothing of the weight away.

Yet fancy not its nature simple so.

For an impalpable aura, mixed with heat,

Deserts the dying, and heat draws off the air;

And heat there's none, unless commixed with air:

For, since the nature of all heat is rare,

Athrough it many seeds of air must move.

Thus nature of mind is triple; yet those all

Suffice not for creating sense- since mind

Accepteth not that aught of these can cause

Sense-bearing motions, and much less the thoughts

A man revolves in mind. So unto these

Must added be a somewhat, and a fourth;

That somewhat's altogether void of name;

Than which existeth naught more mobile, naught

More an impalpable, of elements

More small and smooth and round. That first transmits

Sense-bearing motions through the frame, for that

Is roused the first, composed of little shapes;

Thence heat and viewless force of wind take up

The motions, and thence air, and thence all things

Are put in motion; the blood is strook, and then

The vitals all begin to feel, and last

To bones and marrow the sensation comes-

Pleasure or torment. Nor will pain for naught

Enter so far, nor a sharp ill seep through,

But all things be perturbed to that degree

That room for life will fail, and parts of soul

Will scatter through the body's every pore.

Yet as a rule, almost upon the skin

These motion aIl are stopped, and this is why

We have the power to retain our life.

Now in my eagerness to tell thee how

They are commixed, through what unions fit

They function so, my country's pauper-speech

Constrains me sadly. As I can, however,

I'll touch some points and pass.

In such a wise

Course these primordials 'mongst one another

With inter-motions that no one can be

From other sundered, nor its agency

Perform, if once divided by a space;

Like many powers in one body they work.

As in the flesh of any creature still

Is odour and savour and a certain warmth,

And yet from all of these one bulk of body

Is made complete, so, viewless force of wind

And warmth and air, commingled, do create

One nature, by that mobile energy

Assisted which from out itself to them

Imparts initial motion, whereby first

Sense-bearing motion along the vitals springs.

For lurks this essence far and deep and under,

Nor in our body is aught more shut from view,

And 'tis the very soul of all the soul.

And as within our members and whole frame

The energy of mind and power of soul

Is mixed and latent, since create it is

Of bodies small and few, so lurks this fourth,

This essence void of name, composed of small,

And seems the very soul of all the soul,

And holds dominion o'er the body all.
