Entablature

Entablature is a term in classic architecture applied to the ornamented portion of a building which rests in horizontal position upon
supporting columns. It is a lintel used in classical buildings. Such lintels found in classical architecture are horizontal and continuous or uninterrupted. It is supported either by columns or a wall that is comprised of the architrave, frieze, and cornice.

In fact, Entablature is subdivided into three parts, the lower portion being called the architrave, the middle portion the frieze, and the uppermost the cornice. The depth assigned to these parts varies in the different schools, but the whole entablature generally measures twice the diameter of the column.
