In his tales, Mr. Poe has chosen to exhibit his power chiefly in that dim region which stretches from the very utmost limits of the probable into the weird confines of superstition and unreality. He combines in a very remarkable manner two faculties which are seldom found united; a power of influencing the mind of the reader by the impalpable shadows of mystery, and a minuteness of detail which does not leave a pin or a button unnoticed. Both are, in truth, the natural results of the predominating quality of his mind, to which we have before alluded, analysis. It is this which distinguishes the artist. His mind at once reaches forward to the effect to be produced. Having resolved to bring about certain emotions in the reader, he makes all subordinate parts tend strictly to the common centre. Even his mystery is mathematical to his own mind. To him X is a known quantity all along. In any picture that he paints he understands the chemical properties of all his colors. However vague some of his figures may seem, however formless the shadows, to him the outline is as clear and distinct as that of a geometrical diagram. For this reason Mr. Poe has no sympathy with Mysticism. The Mystic dwells in the mystery, is enveloped with it; it colors all his thoughts; it affects his optic nerve especially, and the commonest things get a rainbow edging from it. Mr. Poe, on the other hand, is a spectator _ab extra_. He analyzes, he dissects, he watches “with an eye serene, The very pulse of the machine,” for such it practically is to him, with wheels and cogs and piston-rods, all working to produce a certain end. This analyzing tendency of his mind balances the poetical, and by giving him the patience to be minute, enables him to throw a wonderful reality into his most unreal fancies. A monomania he paints with great power. He loves to dissect one of these cancers of the mind, and to trace all the subtle ramifications of its roots. In raising images of horror, also, he has strange success, conveying to us sometimes by a dusky hint some terrible _doubt_ which is the secret of all horror. He leaves to imagination the task of finishing the picture, a task to which only she is competent. “For much imaginary work was there; Conceit deceitful, so compact, so kind, That for Achilles’ image stood his spear Grasped in an armed hand; himself behind Was left unseen, save to the eye of mind.” Besides the merit of conception, Mr. Poe’s writings have also that of form.
