to be frequent, we may assume it to be beautiful; and assume that which is most frequent to be most beautiful: I mean, of course, _visibly_ frequent; for the forms of things which are hidden in caverns of the earth, or in the anatomy of animal frames, are evidently not intended by their Maker to bear the habitual gaze of man. And, again, by frequency I mean that limited and isolated frequency which is characteristic of all perfection; not mere multitude: as a rose is a common flower, but yet there are not so many roses on the tree as there are leaves. In this respect Nature is sparing of her highest, and lavish of her less, beauty; but I call the flower as frequent as the leaf, because, each in its allotted quantity, where the one is, there will ordinarily be the other. IV. The first so-called ornament, then, which I would attack is that Greek fret, now, I believe, usually known by the Italian name Guilloche, which is exactly a case in point. It so happens that in crystals of bismuth formed by the unagitated cooling of the melted metal, there occurs a natural resemblance of it almost perfect. But crystals of bismuth not only are of unusual occurrence in every-day life, but their form is, as far as I know, unique among minerals; and not only unique, but only attainable by an artificial process, the metal itself never being found pure. I do not remember any other substance or arrangement which presents a resemblance to this Greek ornament; and I think that I may trust my remembrance as including most of the arrangements which occur in the outward forms of common and familiar things. On this ground, then, I allege that ornament to be ugly; or, in the literal sense of the word, monstrous; different from anything which it is the nature of man to admire: and I think an uncarved fillet or plinth infinitely preferable to one covered with this vile concatenation of straight lines: unless indeed it be employed as a foil to a true ornament, which it may, perhaps, sometimes with advantage; or excessively small, as it occurs on coins, the harshness of its arrangement being less perceived.
