A while ago I wrote about this Frank Godwin painting. I just got an email from a Frank Godwin collector that tells me it was published in a1921 edition of The Blue Fairy Book for "The Story of Prince Ahmed and the Fairy Paribanou." The caption is, "He came to some steep craggy rocks, which were bounds to his journey and were situated in a barren country."He also mentioned that the colors in the book are a bit different than what is seen here, pointing out the white at the top was more of a purple.

Thank you, Mr. Sawyer, for taking the time to write in!
