Percy Shelley Buffs:

I start my Parent-Child Speech and Child Custody Speech Restrictions paper with the story of Percy Shelley, who lost custody of his children largely because he was an atheist. It would be really cool, I think, to get an epigraph from one of Shelley's poems that relates either (1) to a parent's love for his children, and pain at being parted from them, or (2) to Shelley's atheism. I assume there should be plenty of the latter, but I'm not sure about the former. I also need it to be terse, preferably a half dozen lines or less.

If any of you know your Shelley, or know people who know their Shelley, and can help out, I'd be much obliged. Please just post the answers, if any, in the comments. Many thanks!
