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.
