O vanity of sickness! fierce extremes
In their continuance will not feel themselves.
Death, having prey'd upon the outward parts,
Leaves them invisible, and his siege is now
Against the mind, the which he pricks and wounds
With many legions of strange fantasies,
Which, in their throng and press to that last hold,
Confound themselves. 'Tis strange that death
I am the cygnet to this pale faint swan,
Who chants a doleful hymn to his own death,
And from the organ-pipe of frailty sings
His soul and body to their lasting rest.
