Gothic romance contains magic mirrors wherein one can see any person he wishes no matter how distant he may be, and watch his movements after the fashion of a private moving-picture show,--such as that used by Ambrosio.[22] There are enchanted wands with power to transform men to beasts or _vice versa_, as in _The Hunt of Eildon_. There are crystal balls that reveal not only what is going on in distant parts, but show the future as well.[23] The same volume describes magic swords that bear changing hieroglyphics to be read only by enchantment and other uncanny objects. These will serve to illustrate the preternatural powers possessed by inanimate objects in the terror literature. In some instances the motif is used with effectiveness, definitely heightening the impression of the weird in a way that human supernaturalism could not accomplish. We do not see here the mechanistic supernaturalism, which is to become important in later tales, and the effects here are crude, yet of interest in themselves and as suggesting later uses of the idea. [22] In _The Monk_. [23] As in _Vathek_. Dæmonology manifests itself in the supernatural science in the Gothic novels as well as in the characterization of the devil and his confreres. We have diabolical chemistry besides alchemy, astrology, hypnotism, ventriloquism, search for the philosopher's stone, infernal biology, and the other scientific twists of supernaturalism. In _Vathek_, where we have a regular array of ghostliness, we see a magic potion that instantly cures any disease however deadly,--the progenitor of the modern patent medicine. There is an Indian magician who writes his messages on the high heavens themselves. Vathek's mother is an industrious alchemist strangling an assembly of prominent citizens in order to use their cadavers in her laboratory, where she stews them up with serpent's oil, mummies, and skulls, concocting therefrom a powerful potion. Vathek has an uncurbed curiosity that leads him into various experiments, to peer into the secrets of astrology, alchemy, sorcery, and kindred sciences. He uses a magic drink that gives the semblance of death, like that used later in _The Monk_, as earlier, of course, in _Romeo and Juliet_, and elsewhere. The Moor in _Zofloya_ is well versed in dæmonic science. He tells of chemical experiments where he forces everyone to do his will or die. By his potions he can change hate into love or love into hate, and can give a drug which produces semi-insanity. Under the influence of this a man weds a dæmonic temptress thinking her the woman he loves, then commits suicide when he wakes to the truth. This reminds us of Sax Rohmer's Fu-Manchu stories of diabolic hypodermics that produce insanity.
