Incredible painting by Arnold Bocklin,a Swiss painter. The title was not actually given to the piece by Bocklin who simply refered to it by the original request, for an 'image to dream by' There are actually five variations on the original composition. All have the same boat and tall figure heading towards or away from an imposing desolate isle. Also the title of an obscure science fiction story by Roger Zelazny. The main character is a terraformer who shapes worlds. One of his worlds is in part inspired by the painting.
