the objects of creation, and the same in its constituent elements, whether it be sought in the clefts and folds of shaggy hair, or in the chasms and rents of rocks, or in the hanging of thickets or hill sides, or in the alternations of gaiety and gloom in the variegation of the shell, the plume, or the cloud. XVI. Now, to return to our immediate subject, it so happens that, in architecture, the superinduced and accidental beauty is most commonly inconsistent with the preservation of original character, and the picturesque is therefore sought in ruin, and supposed to consist in decay. Whereas, even when so sought, it consists in the mere sublimity of the rents, or fractures, or stains, or vegetation, which assimilate the architecture with the work of Nature, and bestow upon it those circumstances of color and form which are universally beloved by the eye of man. So far as this is done, to the extinction of the true characters of the architecture, it is picturesque, and the artist who looks to the stem of the ivy instead of the shaft of the pillar, is carrying out in more daring freedom the debased sculptor's choice of the hair instead of the countenance. But so far as it can be rendered consistent with the inherent character, the picturesque or extraneous sublimity of architecture has just this of nobler function in it than that of any other object whatsoever, that it is an exponent of age, of that in which, as has been said, the greatest glory of a building consists; and, therefore, the external signs of this glory, having power and purpose greater than any belonging to their mere sensible beauty, may be considered as taking rank among pure and essential character; so essential to my mind, that I think a building cannot be considered as in its prime until four or five centuries have passed over it; and that the entire choice and arrangement of its details should have reference to their appearance after that period, so that none should be admitted which would suffer material injury either by the weather-staining, or the mechanical degradation which the lapse of such a period would necessitate.
