The Composite Order - Decorative Column



Composite Columns The composite entablature uses the same common proportions as the Corinthian entablature. The elements of the cornice are delineated by five equal divisions. There is a cymatium (cyma recta) sitting at the top of the cornice and then the corona with its cyma reversa and smooth fascia. The most distinctive feature of the entablature is a dentil band placed below the cyma reversa. There is an ovolo below the dentils. A conge angles down into the higher moldings of the architrave. Below the moldings, there are two separate bands. The Composite order base uses one bead to separate the two scotias, while the Corinthian uses two beads. The lower scotia is also a little larger than the upper scotia.

There are common traits in both the Composite and the Corinthian capitals. The Composite capital contains an echinus and astragal set below the abacus. The abacus is made up of an ovolo, fillet, conge, and fascia. There is a cylindrical bell below the abacus. The lower part of the capital is adorned with two rows of acanthus leaves, similar to the Corinthian. Each pair of caulicoli located at the leaves’ second tier ends in a single bud or flower facing each other. Between the bud and the abacus, the astragal and echinus (with egg-and-dart motif) are placed. From the base of the abacus, the volutes continue down to sit on the second tier of leaves. Sprigs of honeysuckle are used to spring from the fillet of the volute, filling in the space next to the egg-and-dart. Above the echinus, each volute contains a fleuron which is usually leafier than the Corinthian version.
