What is the Renaissance technique of forming stonework with roughened surfaces and recessed joints called?

• A. Rustication
• B. Ashlar
• C. Tracery
• D. Polychrome

Answer: (A)

Rustication creates a bold, textured stone surface by leaving the faces roughened and setting the blocks with deep, recessed joints. In Renaissance architecture this effect emphasizes mass and solidity, often used on the ground floors of palazzi to give a strong base and a contrast with smoother upper stories. The rough faces catch light differently and the deep grooves between blocks produce pronounced shadow lines, enhancing the sense of weight and hierarchy. This technique is distinct from ashlar, which uses smooth, finely dressed blocks; tracery, which refers to decorative stonework in windows; and polychrome, which describes multi-colored stone or painting. So rustication is the term that fits the description.
