Mrs. Sutherland Orr writes that while Browning was one day strolling
through Dulwich Wood "the image flashed upon him of someone walking ...
alone through life; one apparently too obscure to leave a trace of his
or her passage, yet exercising a lasting though unconscious influence at
every step of it; and the image shaped itself into the little
silk-winder of Asolo, Felippa, or Pippa."
