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
