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.
The Facia is generally plain, but the decoration, if used should, following the principle, be rectilinear in character; such as vertical flutings, or the key detail, both of which are used.
