In attempting to make a regularly constructed narrative depend on supernatural agencies, Walpole undoubtedly succeeded as far as success was possible. But it may be said without hesitation that real success was unattainable. The very merits of "The Castle of Otranto" sustain this decision. The experiment had a fair trial. The narrative of Manfred's crimes and the punishments visited upon them, the characters and actions of subordinate personages are all managed with skill; while the supernatural agencies are introduced at the proper times and have the expected effects. But the real test of success in such an attempt must lie in the impression made on the reader's mind. And this impression may be of two kinds. Let us imagine a group of young people sitting about the dying embers of a fire on a winter's evening, listening to a ghost story. The black darkness, the sound of the wind howling without, accord with the low tones, the dim light, and the tale of horror within. The minds of the listeners insensibly cast off their ordinary trains of thought, and give themselves up to the unreal impressions of the moment. The incredible circumstances of the apparition are accepted without question or criticism; the impression of the supernatural occurrences is alone thought of and enjoyed. But now, let the same tale be read aloud after breakfast, from a newspaper, with the affidavits of the witnesses of the apparition duly attached, and only laughter can be the result. Now let us apply the same test to romance. We open the "Morte d'Arthur"; we find ourselves at once in an unreal, almost nameless land; we meet with knights whom we only know apart by their armor, and queens ambling through pathless forests on white palfreys; we attend brilliant tournaments and witness superhuman deeds of arms. Our minds, untroubled by scepticism and thoughtless of unreality, yield themselves to the poetical illusion. Who stops to think of the incredible when Sir Bedivere hurls into the lake the dying Arthur's sword Excalibur? Then Sir Bedivere departed, and went to the sword, and lightly took it up, and went to the water side, and there he bound the girdle about the hilts, and then he threw the sword as far into the water as he might, and there came an arm and an hand above the water, and met it, and caught it, and so shook it thrice and brandished, and then vanished away the hand with the sword in the water. But when we are introduced to the castle of Otranto, when we know its dimensions and appearance, when we have become acquainted with its inmates, and have been made to realize that they are flesh and blood like ourselves, we cannot receive without a shock the account of the supernatural occurrences by which they are affected. It is as if we listened to a ghost story in the glare of daylight, and in the full activity of our critical faculties.
