Definition

1. Noun:
   • (Architecture) An arch constructed of masonry courses that are corbelled until they meet: A "corbel arch" is a structural element in architecture. It is not a true arch with wedge-shaped voussoirs. Instead, it is formed by building up horizontal layers of stone or brick, with each layer projecting slightly inward beyond the one below it. This corbelling continues from both sides until the two sides meet at the top, often capped by a single stone.

Examples of Usage

• Noun:
  • The ancient Mycenaean tombs feature impressive corbel arches.
  • Unlike a Roman arch, a corbel arch relies on the principle of corbelling for its support.

Advanced Usage

• Structural Principle: The term describes a specific, ancient construction technique. It is often discussed in contrast to a "true arch" or "voussoir arch."
  • The stability of a corbel arch depends on the weight and the careful overlapping of each course.
