A picture at Fano

Dear and great Angel, wouldst thou only leave
  That child, when thou hast done with him, for me!
Let me sit all the day here, that when eve
  Shall find performed thy special ministry,
And time come for departure, thou, suspending
Thy flight, mayst see another child for tending,
  Another still, to quiet and retrieve.

 ... 

If this was ever granted, I would rest
  My bead beneath thine, while thy healing hands
Close-covered both my eyes beside thy breast,
  Pressing the brain, which too much thought expands,
Back to its proper size again, and smoothing
Distortion down till every nerve had soothing,
  And all lay quiet, happy and suppressed.
