_B._ May not the reverie of the reader be dissipated or disturbed by disagreeable images being presented to his imagination, as well as by improbable or incongruous ones? _P_. Certainly; he will endeavour to rouse himself from a disagreeable reverie, as from the night-mare. And from this may be discovered the line of boundary between the Tragic and the Horrid: which line, however, will veer a little this way or that, according to the prevailing manners of the age or country, and the peculiar associations of ideas, or idiosyncracy of mind, of individuals. For instance, if an artist should represent the death of an officer in battle, by shewing a little blood on the bosom of his shirt, as if a bullet had there penetrated, the dying figure would affect the beholder with pity; and if fortitude was at the same time expressed in his countenance, admiration would be added to our pity. On the contrary, if the artist should chuse to represent his thigh as shot away by a cannon ball, and should exhibit the bleeding flesh and shattered bone of the stump, the picture would introduce into our minds ideas from a butcher's shop, or a surgeon's operation-room, and we should turn from it with disgust. So if characters were brought upon the stage with their limbs disjointed by torturing instruments, and the floor covered with clotted blood and scattered brains, our theatric reverie would be destroyed by disgust, and we should leave the play-house with detestation. The Painters have been more guilty in this respect than the Poets; the cruelty of Apollo in flaying Marcias alive is a favourite subject with the antient artists: and the tortures of expiring martyrs have disgraced the modern ones. It requires little genius to exhibit the muscles in convulsive action either by the pencil or the chissel, because the interstices are deep, and the lines strongly defined: but those tender gradations of muscular action, which constitute the graceful attitudes of the body, are difficult to conceive or to execute, except by a master of nice discernment and cultivated taste. _B._ By what definition would you distinguish the Horrid from the Tragic? _P._ I suppose the latter consists of Distress attended with Pity, which is said to be allied to Love, the most agreeable of all our passions; and the former in Distress, accompanied with Disgust, which is allied to Hate, and is one of our most disagreeable sensations. Hence, when horrid scenes of cruelty are represented in pictures, we wish to disbelieve their existence, and voluntarily exert ourselves to escape from the deception: whereas the bitter cup of true Tragedy is mingled with some sweet consolatory drops, which endear our tears, and we continue to contemplate the interesting delusion with a delight which it is not easy to explain.
