I should have known the source of the poem below. Dances with SandyBottom googled it and found that it was written by Sissy, wife of artist Walter Inglis Anderson. I must have come across it when I read "Fortune's Favorite Child: The Uneasy Life of Walter Anderson" by Christopher Maurer. It's one of my favorite biographies - don't know why I did not write down the source when I read it six years ago. The artist's life is a fascinating look at the tension between creativity and mania. Throw in a southern family, the Gulf Coast and a painter rowing to barrier islands to look for inspiration and you've got a great read.
Thanks for tracking that down Paul.
