USA HISTORY

Detailed explanation-1: -The earliest ones date to the 16th century BC. Some similarities are found between the Hittite and Mycenaean construction techniques. Yet the Hittite corbelled vaults are earlier by about 300 years.

Detailed explanation-2: -The Mayans used corbelling techniques for walkways, entryways, and vaults. Another great example of a corbel arch is The Treasury of Atreus in Greece, which was built in the 13th century B.C. A little later on from the ancient Greeks and Mayans, the Vikings and then the Normans widely used corbelled arches.

Detailed explanation-3: -corbel, in architecture, bracket or weight-carrying member, built deeply into the wall so that the pressure on its embedded portion counteracts any tendency to overturn or fall outward. The name derives from a French word meaning crow, because of the corbel’s beaklike shape.

Detailed explanation-4: -“The corbel arch and corbel vault use the technique [of corbelling] to make openings in walls and to form ceilings”. A corbelled (false) roof or vault and a corbelled arch are prototypes of their structural counterparts in the history of architecture.
