Here is a very noble picture; and in what does this poetical picture consist? In images of a tower, an archangel, the sun rising through mists, or in an eclipse, the ruin of monarchs and the revolutions of kingdoms. The mind is hurried out of itself, by a crowd of great and confused images; which affect because they are crowded and confused. For separate them, and you lose much of the greatness; and join them, and you infallibly lose the clearness. The images raised by poetry are always of this obscure kind; though in general the effects of poetry are by no means to be attributed to the images it raises; which point we shall examine more at large hereafter.[14] But painting, when we have allowed for the pleasure of imitation, can only affect simply by the images it presents; and even in painting, a judicious obscurity in some things contributes to the effect of the picture; because the images in painting are exactly similar to those in nature; and in nature, dark, confused, uncertain images have a greater power on the fancy to form the grander passions, than those have which are more clear and determinate. But where and when this observation may be applied to practice, and how far it shall be extended, will be better deduced from the nature of the subject, and from the occasion, than from any rules that can be given. I am sensible that this idea has met with opposition, and is likely still to be rejected by several. But let it be considered that hardly anything can strike the mind with its greatness, which does not make some sort of approach towards infinity; which nothing can do whilst we are able to perceive its bounds; but to see an object distinctly, and to perceive its bounds, is one and the same thing. A clear idea is therefore another name for a little idea. There is a passage in the book of Job amazingly sublime, and this sublimity is principally due to the terrible uncertainty of the thing described: _In thoughts from the visions of the night, when deep sleep falleth upon men, fear came upon me and trembling, which made all my bones to shake. Then a spirit passed before my face. The hair of my flesh stood up. It stood still_, but I could not discern the form thereof; _an image was before mine eyes; there was silence; and I heard a voice,--Shall mortal man be more just than God?_ We are first prepared with the utmost solemnity for the vision; we are first terrified, before we are let even into the obscure cause of our emotion: but when this grand cause of terror makes its appearance, what is it? Is it not wrapt up in the shades of its own incomprehensible darkness, more awful, more striking, more terrible, than the liveliest description, than the clearest painting, could possibly represent it? When painters have attempted to give us clear representations of these very fanciful and terrible ideas, they have, I think, almost always failed; insomuch that I have been at a loss, in all
