A pediment is a classical architectural element consisting of the triangular section found above the horizontal structure, typically supported by columns. The gable end of the pediment is surrounded by the cornice moulding. The tympanum, or triangular area within the pediment, was often decorated with sculptures and reliefs demonstrating scenes of Greek and Roman mythology or allegorical figures it also consisted of many bright colours suitable to the nature of the building being adorned.
History
The pediment is found in classical Greek temples, renaissance, and neo-classical architecture. A prominent example is the Parthenon, where it served as a palette for beautiful, intricate sculptural detail, in the Roman Pantheon no such sculpture was intended.

History
The pediment is found in classical Greek temples, renaissance, and neo-classical architecture. A prominent example is the Parthenon, where it served as a palette for beautiful, intricate sculptural detail, in the Roman Pantheon no such sculpture was intended. This was developed in the architecture of ancient Greece. In Ancient Rome, the Renaissance, and later architectural revivals, the pediment was used as a non-structural element over windows, doors and aedicules.
A variant is the "segmental" pediment, where the normal angular slope of the raking cornice is replaced by one in the form of a segment of a circle, in the manner of a depressed arch. Both traditional and segmental pediments have "broken" and "open" forms. In the broken pediment the raking cornice is left open at the apex. The open pediment is open along the base – often used in Georgian style architecture. A further variant is the "Swan-necked" pediment, where the raking cornice is in the form of two S-shaped brackets. The decorations in the tympanum can extend through these openings, enriched with "Alto-relievo" sculpture, "tondo" paintings, mirrors or windows. These forms were adopted in Mannerist architecture, and applied to furniture designed, or inspired, by Thomas Chippendale.

In geologyIn geology, a pediment is rock which slightly slopes upward along graded surfaces of rocks of various resistance. Gilbert (1877) first described pediments on the upturned edges of tilted beds of Henry Mountains in Utah. They slightly relate to the profile of graded streams.
