§ XIX. I have not in this chapter spoken at all of the profiles which are given in Northern architecture to the projections of the lower members of the base, _b_ and _c_ in Fig. II., nor of the methods in which both these, and the rolls of the mouldings in Plate X., are decorated, especially in Roman architecture, with superadded chain work or chasing of various patterns. Of the first I have not spoken, because I shall have no occasion to allude to them in the following essay; nor of the second, because I consider them barbarisms. Decorated rolls and decorated ogee profiles, such, for instance, as the base of the Arc de l'Etoile at Paris, are among the richest and farthest refinements of decorative appliances; and they ought always to be reserved for jambs, cornices, and archivolts: if you begin with them in the base, you have no power of refining your decorations as you ascend, and, which is still worse, you put your most delicate work on the jutting portions of the foundation,--the very portions which are most exposed to abrasion. The best expression of a base is that of stern endurance,--the look of being able to bear roughing; or, if the whole building is so delicate that no one can be expected to treat even its base with unkindness,[80] then at least the expression of quiet, prefatory simplicity. The angle spur may receive such decoration as we have seen, because it is one of the most important features in the whole building; and the eye is always so attracted to it that it cannot be in rich architecture left altogether blank; the eye is stayed upon it by its position, but glides, and ought to glide, along the basic rolls to take measurement of their length: and even with all this added fitness, the ornament of the basic spur is best, in the long run, when it is boldest and simplest. The base above described, § XVIII., as the most beautiful I ever saw, was not for that reason the best I ever saw: beautiful in its place, in a quiet corner of a Baptistery sheeted with jasper and alabaster, it would have been utterly wrong, nay, even offensive, if used in sterner work, or repeated along a whole colonnade. The base No. 10 of Plate XII. is the richest with which I was ever perfectly satisfied for general service; and the basic spurs of the building which I have named as the best Gothic monument in the world (p. 141), have no ornament upon them whatever. The adaptation, therefore, of rich cornice and roll mouldings to the level and ordinary lines of bases, whether of walls or shafts, I hold to be one of the worst barbarisms which the Roman and Renaissance architects ever committed; and that nothing can afterwards redeem the effeminacy and vulgarity of the buildings in which it prominently takes place.
