The question, professedly that of the _province_, slides away into what is the _nature_ of poetry. The object of poetry is, we think, to show the infinite through the finite--to reveal the ideal in the real--it seeks, by clustering analogies and associations around objects, to give them a beautiful, or sublime, or interesting, or terrible aspect which is not entirely their own. Now, as all objects in comparison with the infinite are finite, and all realities in comparison with the ideal are little, it follows that between artificial and natural objects, as fitted for poetic purposes, there is no immense disparity, and that both are capable of poetic treatment. Both, accordingly, have become subservient to high poetic effect; and even the preponderance, whatever it be on the part of natural objects, has sometimes been equalised by the power of genius, and artificial things have often been made to wring the heart or awaken the fancy, as much or more than the other class. Think, for instance, of the words in Lear,

"Prithee, undo this button. Thank you, sir."

What more contemptibly artificial than a button? And yet, beating in the wind of the hysterical passion which is tearing the heart of the poor dying king, what a powerful index of misery it becomes, and its "undoing," as the sign of the end of the tragedy, and the letting forth of the great injured soul, has melted many to tears! When Lady Macbeth exclaims, in that terrible crisis,

"Give me the daggers!"'

who feels not, that, although a dagger be only an artificial thing, no natural or supernatural thing, not the flaming sword of the Cherubim itself, could seem, in the circumstances, more fearfully sublime. What action more artificial than dancing, and yet how grand it seems, in Ford's heroine, who continues to dance on till the ball is finished, while the news of "death, and death, and death" of friend, brother, husband, are successively recounted to her--and then herself expires! There seems no comparison between a diamond and a star, and yet a Shakspeare or a Schiller could so describe the trembling of a diamond on the brow say of Belshazzar when the apparition of the writing on the wall disturbed his impious feast, that it would seem more ideal and more magnificent than a star "trembling on the hand of God" when newly created, or trembling on the verge of everlasting darkness, when its hour had come. A slipper seems a very commonplace object; but how interesting the veritable slipper of Empedocles, who flung himself into Etna, whose slipper was disgorged by the volcano, and as a link, connecting the seen with the unseen, the grassy earth with the burning entrails of the eternal furnace, became intensely imaginative! A feather in a cap (even though it were an eagle's) seems, from its position, an object sufficiently artificial; but how affecting the black plume of Ravenswood floating on the waves which had engulphed the proud head that once bore it, and which old Caleb took up, dried, and placed in his bosom!
