ENTABLATURE, in architecture, the assemblage of hori zontal mouldings and bands, supported by, and immediately above, the columns of classic buildings, or similar forms in any other style (see ORDER). It is usually divided into three main portions; the lowest, called the architrave (q.v.), originally the beam run ning from support to support; the central one called a frieze (q.v.), consisting of an unmoulded band with or without orna ment ; and the topmost, called the cornice (q.v.), formed of a series of mouldings that project from the face of the frieze. Oc casionally, in Greek and Renais sance, work, the frieze is omitted, as in the caryatid porch of the Erectheum at Athens. In Geor gian and American colonial work, the architrave is sometimes omitted, as in many of the designs of Robert Adam.
