Pedimental sculpture

Pedimental sculpture is a form of architectural sculpture designed for installation in the tympanum, the space enclosed by the architectural element called the pediment. Originally a feature of Ancient Greek architecture, pedimental sculpture started as a means to decorate a pediment in its simplest form: a low triangle, like a gable, above an horizontal base or entablature.[2] However, as classical architecture developed from the basis of Ancient Greek and Roman architecture, the varieties of pedimental sculpture also developed. The sculpture can be either freestanding or relief sculpture, in which case it is attached to the back wall of the pediment. Harris in The Illustrated Dictionary of Historic Architecture defines pediment as "In classical architecture, the triangular gable end of the roof above the horizontal cornice, often filled with sculpture." Pediments can also be used to crown doors or windows.[3]

In Romanesque architecture, and very often in Gothic architecture, the tympanum is usually semi-circular at the top, and the sculptural groups, usually with religious subjects, adapted to fit the new spaces. In the Renaissance triangular pediments returned, as gradually did sculptural groups within them, becoming very popular for important buildings in the 19th century.
