The Ionic Capital And Entablature

Plate 19 shows the setting out of the entablature in detail, and depicts the four-sided capital. Details of this and the alternative, directional capital are given in the succeeding plates.

It is difficult to decide whether the Ionic architrave should be of two faces or three. There is no consensus among the Renaissance authorities. Greek prototypes more often than not employ a triple division, but both Gibbs and Chambers reserve this more elaborate subdivision for the Corinthian, as the most decorative of the orders. I have followed this practice in the plate. It should be noted that the lower face of the architrave is considerably narrower than the upper - an equal division looks dull and is to be avoided.

The frieze may be either flat, as shown, or pulvinated, as in Palladio's Ionic in plate 6. The pulvinated frieze has a convex face, the centre of the curve lying on the column centre. If flat, the frieze may be enriched with bas-reliefs. All the principal mouldings are enriched with ornament - the extent to which this is applied depends on the scale and purpose of the particular design - except for the large crowning cyma and its terminal fillet, which are plain, certainly where an external order is proposed. The soffit of the corona is generally plain, though in external orders it may be weathered, with a drip moulding formed along its outer edge. At the corners, where the march of the dentils is necessarily interrupted, it is common for a circular ornament, often in the form of a pineapple or an acorn, to be suspended from the soffit.
