In âThe Domain of Arnheimâ Poe combines an explication of his aesthetic theory and a physical description of a landscape-garden, Arnheim. The builder of Arnheim, Ellison, is described by a narrator as a fabulously wealthy man, interested âinstinctively . . . . in the creation of novel forms of Beautyâ . He is interested in shaping nature, in molding it into a âpurely physical loveliness.â
