Anotations

Scope note:

Semi-circular or triangular recessed spaces within a pediment comprising stone or masonry enclosed by an arch, usually supported by a lintel. Tympana are normally set above doors, but also occur in windows and wall arcades. They may be ornamented with sculptural or painted decoration. The term more commonly refers to the Medieval-era arch areas over a doorway decorated with Christian iconography, rather than the ancient Roman or Greek examples from which they evolved, which are most often triangular.
