Lucretius, De Rerum Natura
William Ellery Leonard, Ed.

     Now, by what modes this sleep
Pours through our members waters of repose
And frees the breast from cares of mind, I'll tell
In verses sweeter than they many are;
Even as the swan's slight note is better far
Than that dispersed clamour of the cranes
Among the southwind's aery clouds. Do thou
Give me sharp ears and a sagacious mind,-
That thou mayst not deny the things to be
Whereof I'm speaking, nor depart away
With bosom scorning these the spoken truths,
Thyself at fault unable to perceive.
Sleep chiefly comes when energy of soul
Hath now been scattered through the frame, and part
Expelled abroad and gone away, and part
Crammed back and settling deep within the frame-
Whereafter then our loosened members droop.
For doubt is none that by the work of soul
Exist in us this sense, and when by slumber
That sense is thwarted, we are bound to think
The soul confounded and expelled abroad-
Yet not entirely, else the frame would lie
Drenched in the everlasting cold of death.
In sooth, where no one part of soul remained
Lurking among the members, even as fire
Lurks buried under many ashes, whence
Could sense amain rekindled be in members,
As flame can rise anew from unseen fire?
