When used in the cornice or in the capping of pedestals its under face is generally recessed, this recess being equal to the height of the top fillet of supporting moulding. Only occasionally the Facia is furnished with an upper fillet (for instance, when it occurs immediately below the Cyma Recta) to which it is reconciled by a Cavetto curve. The Facia is a divisional feature between the mouldings of curved profile to which it is in valuable contrast. _Decoration of Mouldings_ Mouldings may be plain or decorated, usually by carving, the details probably being derived from the painted decoration of an early period. When thus enriched the moulding is formed as to its profile, and the details carved back from the face, leaving the highest parts in the original surface. The carving being deeper and more sharply defined in the case of mouldings that are in shadow. Such, for example, as the Ovolo, and in lighter relief on those more exposed to direct light. The decoration of mouldings ordinarily consists of the repetition of a unit, composed on a central axis, in which curves are contrasted with vertical features. [Illustration: ENRICHMENT OF THE CYMA RECTA ENRICHMENT OF THE FACIA ENRICHMENT OF THE OVOLO ENRICHMENT OF THE CYMA REVERSA ENRICHMENT OF THE TORUS No. 135.] The principle involved is to base the detail on the sectional curvature or profile line. _Orthodox Details_ Thus the orthodox detail of the Ovolo, technically known as the “Egg and Tongue,” consists of a framing curve, which is obtained by repeating the profile on a centre line enclosing an ovoid shape. The angles between the outer curves being occupied by a tongue or dart. As previously stated, this moulding is deeply carved, the ovoid being bold and well-rounded; the edges of the framing curves (in some instances grooved or channelled) being left sharp and precise. Frequently the “Bead and Reel” enrichment occurs at the base of the Ovolo instead of the Fillet, this being the characteristic detail of the Bead or Astragal. The treatment of the Cyma Reversa is identical and results in the detail known as the “Leaf and Dart”; but the carving is not so deep and the relief, in consequence, comparatively slight. _Angle Leaf_ When mouldings meet at mitral angles it is customary to employ a covering leaf the midrib of which forms the angle. The same principle is applicable to the Cyma Recta and the Cavetto, though these mouldings are more often left plain; when decorated the relief is comparatively slight. The Scotia needs no decoration, the cast shadow resulting from its form being sufficiently effective. The Torus, though frequently left plain, can be decorated in various ways. The Guilloche is perhaps the most characteristic, but as suggestive of its function, the Torus is at times carved in the form of a rope or cable. Leaves suggestive of a wreath are used, also a reed band crossed at intervals with ribbons, quite in keeping with the suggestion of binding.
