Whoever will study those inimitable productions, even when standing to gaze at the engravings from them in a print-shop window, will have no difficulty in feeling the justice of Cicero's remark, that all the arts which relate to humanity have a certain common bond, a species of consanguinity between them. The emotion produced by the highest excellence in them all is the same. So intense is this emotion, so burning the delight which it occasions, that it cannot be borne for any length of time: the mind's eye is averted from it as the eyeball is from the line of "insufferable brightness," as Gray calls it, which often precedes the setting of the sun. It is difficult to say in which this burning charm consists. Like genius or beauty, its presence is felt by all, but can be described by none. It would seem to be an emanation of Heaven--a chink, as it were, opened, which lets us feel for a few seconds the ethereal joys of a superior state of existence. But it is needless to seek to define what, all who have felt it must acknowledge, passes all understanding. It is a common saying, even among persons of cultivated taste, that it is hopeless to attempt to advance any thing new on the beauties of ancient authors; that every thing that can be said on the subject has already been exhausted, and that it is in the more recent fields of modern literature that it is alone possible to avoid repetition. We are decidedly of opinion that this idea is erroneous, and that its diffusion has done more than any thing else to degrade criticism to the low station which, with some honourable exceptions, it has so long held in the world of letters. But when ancient excellence is contemplated with a generous eye, even when the mind that sees is but slenderly gifted, who will say that nothing new will occur? When it meets kindred genius, when it is elevated by a congenial spirit, what a noble art does criticism become? What has it proved in the hands of Dryden and Pope, of Wilson and Macaulay? It is in the contemplation of ancient greatness, and its comparison with the parallel efforts of modern genius, that the highest flights of these gifted spirits have been attained, and the native generosity of real intellectual power most strikingly evinced. Criticism of words will soon come to an end; the notes of scholiasts and annotators are easily made, as apothecaries make drugs by pouring from one phial into another. But criticism of things, of ideas, of characters, of conceptions, can never come to an end; for every successive age is bringing forth fresh comparisons to make, and fresh combinations to exhibit. It is the outpouring of a heart overburdened with admiration which must be delivered, and will ever discover a new mode of deliverance.
