“Almost without the first sign of moral principle, or of the concrete and its heroisms, or the simpler affections of the heart, Poe's verses illustrate an intense faculty for technical and abstract beauty, with the rhyming art to excess, an incorrigible propensity towards nocturnal themes, a demoniac undertone behind every page-and, by final judgment, belong among the electric lights of imaginative literature, brilliant and dazzling, but with no heat.”
