any and huge, are moved and hoisted high
By enginery of pulley-blocks and wheels,
With but light strain.

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?

By what devices this strange state and new
May be occasioned, and by what the soul
Can be confounded and the frame grow faint,
I will untangle: see to it, thou, that I
Pour forth my words not unto empty winds.
In first place, body on its outer parts--
Since these are touched by neighbouring aery gusts--
Must there be thumped and strook by blows of air
Repeatedly. And therefore almost all
Are covered either with hides, or else with shells,
Or with the horny callus, or with bark.
Yet this same air lashes their inner parts,
When creatures draw a breath or blow it out.
Wherefore, since body thus is flogged alike
Upon the inside and the out, and blows
Come in upon us through the little pores
Even inward to our body's primal parts
And primal elements, there comes to pass
By slow degrees, along our members then,
A kind of overthrow; for then confounded
Are those arrangem
