Lucretius, De Rerum Natura
William Ellery Leonard, Ed.

     Now will I seek again to bring to mind
How porous a body all things have- a fact
Made manifest in my first canto, too.
For, truly, though to know this doth import
For many things, yet for this very thing
On which straightway I'm going to discourse,
'Tis needful most of all to make it sure
That naught's at hand but body mixed with void.
A first ensample: in grottos, rocks o'erhead
Sweat moisture and distil the oozy drops;
Likewise, from all our body seeps the sweat;
There grows the beard, and along our members all
And along our frame the hairs. Through all our veins
Disseminates the foods, and gives increase
And aliment down to the extreme parts,
Even to the tiniest finger-nails. Likewise,
Through solid bronze the cold and fiery heat
We feel to pass; likewise, we feel them pass
Through gold, through silver, when we clasp in hand
The brimming goblets. And, again, there flit
Voices through houses' hedging walls of stone;
Odour seeps through, and cold, and heat of fire
That's wont to penetrate even strength of iron.
Again, where corselet of the sky girds round
     . . . . . .
And at same time, some Influence of bane,
When from Beyond 'thas stolen into [our world].
And tempests, gathering from the earth and sky,
Back to the sky and earth absorbed retire-
With reason, since there's naught that's fashioned not
With body porous.
