I am trying to find the author and text of a poem quoted in A.S. Byatt's Posession....it is at the very beginning of the book, before the actual book even starts, it follows a quote from Hawthorne and I believe it is part of a poem by either Burns or Browning. I don't have my copy of the book here with me or I would have easy access to it, and I've tried everything I can think of to look it up online. If anyone could help me I would greatly appreciate it.
