Ron Miller has made a career of unveiling the cosmos. His gorgeous renderings of planets, stars and other heavenly objects have appeared in scores of books and magazines. With astronomer William K. Hartmann, he co-authored The Grand Tour, a classic pictorial guide to the solar system. He has also been a production illustrator for science fiction movies such as Dune and Total Recall. More recently he has turned to writing fantasy novels; his latest effort, Bradamant (Timberwolf Press, 2000), is based on the 16th-century epic poem Orlando Furioso. Here Miller discusses the nebulous boundary between science and art.
