Superstructure which lies horizontally upon the columns in classic architecture
Entablature. —A superstructure which lies horizontally upon the columns in classic architecture. It is divided into three parts: the architrave (the supporting member carried from column to column); the frieze (the decorative portion); and the cornice (the crowning and projecting member). Each of the orders has its appropriate entablature, of which both the general height and the subdivisions are regulated by a scale of proportion derived from the diameter of the column. It is occasionally used to complete, architecturally, the upper portion of a wall, even when there are no columns, and in the case of pilasters or detached or engaged columns is sometimes profiled round them.
