Step-by-step explanation:
The horizontal section of a classical order that rests on the columns, typically composed of a cornice, frieze, and architrave, is called the entablature.
In the Doric order, the entablature includes a frieze composed of triglyphs and metopes. The triglyphs are vertical plaques with three divisions, while the metopes are square spaces for either painted or sculpted decoration.
The entablature serves as an important architectural element above the columns, supporting the roof of a structure and providing visual interest and decorative details
