Parapet
A parapet (from the Italian parapetto and/or the French parapet, from Italian para, imperative of Italian parare (to cover, defend) and petto (breast), ultimately from the Latin pectus (breast); the Germans use the term Brustwehr (breast-defence)) consists of a dwarf wall along the edge of a roof, or round a lead flat, terrace walk, etc., to prevent persons from falling over, and as a protection to the defenders in case of a siege.
Parapets are either plain, embattled, perforated or panelled. The last two are found in all styles except the Romanesque.
- Plain parapets are simply portions of the wall generally overhanging a little, with a coping at the top and corbel table below.
- Embattled parapets are sometimes panelled, but oftener pierced for the discharge of arrows, etc.
- Perforated parapets are pierced in various devices as circles, trefoils, quatrefoils and other designs so that the light is seen through.
- Panelled parapets are those ornamented by a series of panels, either oblong or square, and more or less enriched, but not perforated. These are common in the Decorated and Perpendicular periods.
Compare breastwork.
Original text from the 1911 Encyclopaedia Britannica
Many people believe every house should have a parapet: "When you build a new house, make a parapet around your roof so that you may not bring the guilt of bloodshed on your house if someone falls from the roof." -- Deuteronomy 22:8 (NIV)
