Corinthian Entablature
The division of the entablature is the same as that of the Ionic. The total height is divided into ten. Three of these parts form the architrave, three the frieze and four the cornice.
An angle of 45 degrees set off from the top of the frieze will determine the general contour and projection of the cornice.
The cornice is more complex than in the other styles, but a division of eleven will help to determine, three being the height to underside of bead moulding and seven that of the main facia. The lowest moulding of the cornice is a cyma reversa supporting a dentil course with a bead moulding above it. Above the bead there is an ovolo, which forms the bed of a series of brackets known as modillions. The height of the modillions is about one-fifth including the reversa moulding, which, besides completing the modillions, is carried round between them as a support for the upper facia.
The modillions have a profile of ogee form. They are about a sixth of a diameter in width and project about twice their width, and are so spaced as to leave squares between them on the soffit or underside of the corona. The frieze, which may or may not be decorated, is in vertical alignment with the lowest member of the architrave.
The architrave is made up of three facias with intervening mouldings. If the height be divided into two, the upper half is devoted to the first facia and reversa moulding, which latter occupies rather more than one-third; the remaining half is taken up by the other two facias in a diminishing ratio.
