What is the architectural ornament consisting of an assembly of straight lines intersecting at right angles, also known as a key pattern?

• A. Fretwork
• B. Pulpitum
• C. Polychromy
• D. Expressionism

Answer: (A)

Fretwork is an architectural ornament consisting of straight lines intersecting at right angles to form a decorative lattice, often described as a key pattern. This precise arrangement—openwork created by interlaced linear elements—is what defines fretwork, typically cut in wood, plaster, or metal for screens, panels, or window grilles. It emphasizes geometric precision and the play of light and shadow rather than color or figural form. The other terms don’t fit: pulpitum refers to a stage front in ancient theatre, polychromy means using multiple colors, and expressionism denotes a modern style focused on emotional expression rather than a specific ornamental pattern.
