A corbel is an architectural feature that projects from a wall and supports a structure above it. It is typically made of stone, wood, or brick and can be used to support a balcony, roof, or other structure. The term 'corbel' is derived from the French word 'corbeau, ' which means 'RAVEN.' An ORIEL is a type of corbel, usually found in Gothic architecture, that projects from a wall and is supported by brackets or columns. ORIEL windows are often found in churches and other historic buildings.
